Efficacy, safety and tolerability of salbutamol + guaiphenesin + bromhexine (Ascoril) expectorant versus expectorants containing salbutamol and either guaiphenesin or bromhexine in productive cough: a randomised controlled comparative study.

Patients with acute bronchitis, acute exacerbations of chronic bronchitis and asthmatic bronchitis suffer from cough with tenacious bronchial secretions requiring expectorants in addition to bronchodilating therapy. The present one-week, multicentric, prospective, randomised, double-blind study compared the efficacy and tolerability of three expectorant formulations in 426 patients with productive cough associated with varied aetiology after approval by the institutional review boards. Selected patients received 7 days' treatment with either fixed dose combination (FDC) of salbutamol 2 mg + bromhexine HCI 8 mg + guaiphenesin 100 mg (group A) or salbutamol 2 mg+ guaiphenesin 100 mg expectorant (group B) or salbutamol 2 mg + bromhexine 8 mg (group C) thrice daily after obtaining their informed consent. In group A, there was improvement of symptoms in a larger number of patients and earlier onset of action in reducing cough frequency and severity and improving sputum characteristics as compared to the other two groups. More patients in group A reported excellent efficacy (44.4%) as compared to only 14.6% in Group B and 13% in Group C. Cough expectorant containing salbutamol + bromhexine +guaiphenesin could be the expectorant of choice in alleviating productive cough since it scored in terms of efficacy as well as tolerability over salbutamol with either bromhexine or guaiphenesin alone.

Efficacy, safety, and tolerability of microsphere adapalene vs. conventional adapalene for acne vulgaris.

BACKGROUND: The present study was undertaken to compare the efficacy, safety and tolerability of a new microsphere adapalene formulation and conventional adapalene in adult patients with mild to moderate acne vulgaris. MATERIALS AND METHODS: This prospective, randomized, assessor-blind, multi-centric (3 centres) comparative, post-marketing phase IV study was undertaken in 175 patients with mild to moderate acne after approval by respective Institutional review boards. Patients fulfilling selection criteria were randomly assigned to either microsphere adapalene gel or conventional adapalene gel both once daily in the evening for 12 weeks after obtaining their informed consent. Efficacy variables included success rate and percent lesion reduction from baseline. Safety and tolerability was assessed on the basis of physical examination and monitoring of treatment-emergent adverse events. RESULTS: Of the 175 patients (88 in microsphere and 87 in conventional) 21 were lost to follow-up and considered drop-outs. There was a significant decrease (P < 0.05) in mean inflammatory and non-inflammatory lesion and total lesion counts from 1st week onwards in both groups. A significantly lower number of microsphere treated patients (50%) reported a side effect (P < 0.05) as compared to 71.3% in conventional users. A highly significant decrease was observed in dryness and erythema (P < 0.01) in microsphere group compared to conventional. Eight patients in conventional group discontinued therapy due to severe irritation as compared to none in microsphere adapalene group. COMMENT: Therapy with microsphere adapalene provided a better tolerability with minimal irritation compared to conventional adapalene, without compromising efficacy and could be a better therapeutic option for acne.

Comparative assessment of the effectiveness and tolerability of lornoxicam 8 mg BID and diclofenac 50 mg TID in adult indian patients with osteoarthritis of the hip or knee: A 4-week, double-blind, randomized, comparative, multicenter study.

BACKGROUND: Reports of cardiovascular adverse events (AEs) associated with the use of cyclooxygenase-2 inhibitors for the treatment of osteoarthritis (OA) have prompted the quest for a better-tolerated NSAID. OBJECTIVE: The aim of this study was to compare the effectiveness and tolerability of lornoxicam 8 mg BID and diclofenac 50 mg TID in adult Indian patients with OA of the hip or knee. METHODS: This 4-week, double-blind, randomized, comparative, multicenter study was undertaken to compare oral lornoxicam and diclofenac in patients with OA. Patients who met the selection criteria were enrolled consecutively from the outpatient clinics of each of the participating hospitals in India. Participants completed the Western Ontario and McMasters Individual Osteoarthritis Index (WOMAC-OA), WOMAC Composite Index (WOMAC-CI) (for pain, stiffness, and physical function), and a 10-cm visual analog scale (VAS) (0-10 where 0 = no pain and 10 = worst possible pain or severe or excruciating pain) at each study visit (weeks 0 [baseline], 2, and 4 [or at early termination]). Patients' and physicians' global assessments of arthritis control were measured at each study visit when laboratory and clinical AEs were also monitored. The primary end points were the WOMAC-OA, the WOMAC-CI, and VAS scores for pain among the patients who completed the study. RESULTS: Of the 273 patients (159 men, 114 women; mean [SD] age, 44.73 [10.72] years; range, 28-68 years) enrolled in the study, 13 (7 in the lornoxicam group and 6 in the diclofenac group) were lost to follow-up and their effectiveness and tolerability results were not included in the study analysis. Over the 4-week study period, both drugs provided significant (P < 0.05) sustained relief of OA symptoms compared with baseline. Compared with baseline, the mean pain score (WOMAC-CI) decreased 90.6% (13.88 [4.47] vs 1.30 [1.49]; P < 0.05) in the lornoxicam group and 88.9% (14.15 [4.56] vs 1.57 [1.49]; P < 0.05) in the diclofenac group after 4 weeks of treatment. After 4 weeks of treatment, the VAS pain score decreased from baseline 83.1% (8.04 [2.70] vs 1.36 [1.43]; P < 0.05) in the lornoxicam group and 79.3% (7.98 [2.98] vs 1.65 [1.47]; P < 0.05) in the diclofenac group. Compared with baseline, the improvement rated at 2 weeks was not significantly different between the 2 groups. Lornoxicam and diclofenac were well tolerated. The rate of mild to moderate adverse gastrointestinal events was not significantly different in the lornoxicam group compared with the diclofenac group (14.6% vs 18.4%). Similarly, overall tolerability between the 2 groups was not significantly different. None of the patients experienced cardiovascular AEs (eg, edema or increased blood pressure). CONCLUSION: The results of the present study suggest that lornoxicam was comparable to diclofenac in effectiveness and tolerability after 4 weeks of treatment in these adult Indian patients with OA of the hip or knee who completed the study.

Assessment of the efficacy and tolerability of a fixed dose combination of atorvastatin 10 mg + metformin SR 500 mg in diabetic dyslipidaemia in adult Indian patients.

Type 2 diabetes mellitus is associated with a marked increase in the risk of coronary heart disease (CHD) or stroke (by a factor of two to three compared with non-diabetic patients), and cardiovascular disease (CVD) accounts for the majority of deaths among patients with diabetes. A new fixed dose combination containing atorvastatin 10 mg + metformin SR 500 mg is being introduced in the Indian market for the treatment of dyslipidaemia in diabetic patients. The present study was therefore undertaken to assess efficacy, safety and tolerability of a fixed dose combination of atorvastatin 10mg + metformin SR 500mg in adult Indian patients with diabetic dyslipidaemia. The final protocol was approved by relevant ethics committee before the initiation of study. Informed consent was obtained from all the patients prior to enrollment in study. The total duration of study was 14 weeks including two weeks dietary run in period. Patients fulfilling the selection criteria received a single oral tablet of fixed dose combination of atorvastatin 10mg + metformin SR 500mg once daily for 12 weeks. The primary efficacy parameters were assessed by evaluating reduction in fasting and postprandial plasma glucose concentration levels at baseline and thereafter at each follow up visit at 2, 4, 8 and 12 weeks and plasma lipid profile and glycosylated Hb levels at baseline and end of study. The secondary efficacy parameters were assessed by evaluating percentage change from baseline at the end of the study (week 12) in the plasma concentration of the various lipid parameters such as total, HDL-, LDL- and very low density (VLDL)-cholesterol, triglycerides, Apo B, Apo A1, TC/LDL ratio, LDL/ HDL ratio, and percentage of patients achieving LDL-cholesterol goals as per NCEP ATP III guidelines. A total of 213 patients were enrolled in the study. Of these seven patients were lost to follow-up and considered as drop-outs. Therapy with the fixed dose combination of atorvastatin 10 mg + metformin SR 500 mg resulted in a significant reduction in the mean plasma fasting and postprandial glucose levels (35 and 38.8% respectively). There was a steep fall in the HbA1c levels from baseline levels of 8.76% to 6.74% (23.1%). There was also a significant (p < 0.05) reduction in mean total cholesterol (31.2%), LDL cholesterol (35.4%), VLDL-cholesterol (19.6%) and a significant increase HDL-cholesterol (9.5%). Thus there appeared to be trend towards reducing atherosclerosis following therapy with the fixed dose combination of atorvastatin 10 mg + metformin SR 500 mg. Mean body mass index was significantly reduced in the patients in the present study following therapy with the study drugs. The fixed dose combination of atorvastatin with metformin was well tolerated with mostly gastro-intestinal adverse events being reported in the current study. Moreover, most of the adverse events were mild to moderate in intensity and disappeared with continued treatment. In conclusion, the results of the present study suggest that, the fixed dose combination of atorvastatin 10 mg + metformin SR 500 mg is efficacious and well tolerated therapeutic modality in patients with diabetic dyslipidaemia. Furthermore this combination offers dosage convenience to the patient and by virtue of its dual mode of action is a useful addition to the therapeutic armamentarium for patients with diabetic dyslipidaemia.

Evaluation of fixed dose combination (FDC) of telmisartan+ramipril usage in patients with micro-albuminuria and persistent hypertension: A TRIUMPH study.

Micro-albuminuria is a marker for declining kidney function and predicts increasing cardiovascular risk especially in diabetic hypertensives. Angiotensin receptor blockers and angiotensin-converting enzyme inhibitors may slow the progression of proteinuric kidney disease and thus would be valuable in these high risk patients. The present study was undertaken to assess the efficacy and tolerability of a fixed dose combination (FDC) of telmisartan and ramipril in adult Indian patients with sustained stage 2 hypertension, comorbidities and micro-albuminuria. A total 382 patients were enrolled in this multicentric, prospective open, non-comparative phase IV postmarketing surveillance study by 40 physicians in India and treated with FDC of telmisartan 40 mg+ ramipril 5 mg once daily for 12 weeks. A total 370 patients completed the study but 12 patients were lost to follow-up and considered as drop-outs. There was a significant (p<0.05) reduction in the systolic blood pressure (SBP) from 170.89 at baseline to 132. 77 mm Hg at week 12 and diastolic blood pressure (DBP) from 104.47 to 83.30 mm Hg at the end of 12 weeks therapy as well as urine albumin levels from 186.25 mg/24-hour to 62.42 mg/24-hour (66.49%) at the end of 12 weeks. Overall assessment of treatment was rated as good to excellent in 87.3% and fair in 11.4% patients. The most common adverse event reported was cough (5.2%). Results of the present study indicate that the FDC of telmisartan+ramipril brings about significant reductions in the systolic and diastolic blood pressure as well as urine albumin excretion.

An open prospective study on postmarketing evaluation of the efficacy and tolerability of diacerein in osteo-arthritis of the knee (DOK).

According to World Health Organisation osteo-arthritis is the second commonest musculoskeletal problem in the world. Diacerein has been recently introduced in India for the treatment of osteo-arthritis. In view of the ulcerogenic potential of NSAIDs and the cardiotoxicity problems associated with COX-2 inhibitors, diacerein has the potential of being a non-ulcerogenic and non-cardiotoxic alternative respectively to NSAIDs and of COX-2 inhibitors in the treatment of osteo-arthritis. The present study was, therefore, undertaken to evaluate the efficacy and tolerability of diacerein in the treatment of osteo-arthritis. A total 7923 patients with osteo-arthritis of the knee fulfilling the selection criteria were enrolled in this open-label, multicentric postmarketing surveillance study. After a wash-out period of one week, patients were treated with 50mg diacerein tablets administered twice daily for 12 weeks. The primary efficacy variable of the present study was to assess the improvement in the visual analogue scale (VAS) scores for pain. The secondary variable was improvement in patients' and physicians' global assessment of efficacy of therapy. Results indicated that over the 12-week study period, diacerein 50mg tablets provided significant and sustained reduction the VAS pain scores. At baseline, VAS scores were 6.70 +/- 1.78. By the end of the 4th week, there was a significant reduction in the mean VAS scores by 21.8% and by the end of the study the mean VAS scores were further significantly reduced by 59.9%. As per the patients global assessment of treatment, 82.3% of the patients reported good to very good improvement at the end of 12 weeks therapy with diacerein. Similar responses were also recorded by the treating patients. Thus by the end of 12 weeks therapy, according to the physicians 85.5% of the total cases treated with diacerein were rated as having good to very good improvement. Therapy with diacerein was well tolerated and only 5.44% of the patients had an adverse event after treatment with diacerein. The most common adverse events were diarrhoea (2.3%), gastritis (0.99%), nausea (0.61%), abdominal pain or discomfort (0.44%) and vomiting (0.3%). The severity of the adverse events was mild in all the cases and disappeared with continued treatment. None of the patients dropped out of the study on account of adverse events or lack of efficacy. Thus, in conclusion, the results of the present study in a large population of Indian patients indicates that diacerein constitutes a novel approach to the treatment for the short- and long-term symptomatic management in Indian patients with osteo-arthritis of the knee.

Lornoxicam efficacy in acute pain (LEAP) trial.

Parenteral non-steroidal anti-inflammatory drugs (NSAIDs) are useful agents in the treatment of postoperative pain and other acute traumatic painful conditions such as fractures. Clinical trials with lornoxicam, an oxicam derivative, document its efficacy as a potent analgesic with excellent anti-inflammatory properties in painful and or/inflammatory conditions including postoperative pain and arthritic conditions. However, there is no documentation of the efficacy and tolerability of intravenous lornoxicam in Indian patients with acute painful conditions such painful traumatic conditions requiring hospitalisation and parenteral analgesics. The present study was undertaken to evaluate the efficacy and tolerability of intravenous lornoxicam in Indian patients with postoperative pain or other acute painful traumatic conditions requiring hospitalisation and parenteral analgesia in in-office practice conditions. In this multicentric, prospective, open, non-comparative phase IV, postmarketing surveillance study patients admitted in the nursing home for either postoperative pain or painful conditions requiring hospitalisation and parenteral analgesia were enrolled in the study after obtaining their informed consent. Of the 161 patients fulfilling the selection criteria, 148 met the selection criteria and were included in the efficacy analysis. Patients were treated with intravenous lornoxicam 8 mg twice or three times daily as required for up to 3 days. Efficacy variables included changes in severity of pain scores compared to baseline values, onset of pain relief and overall global efficacy. Tolerability was assessed through monitoring of treatment-emergent adverse events, physical examination, assessments of vital signs, and overall global assessment of tolerability. Results indicated that within 1 hour of administration of intravenous lornoxicam, the mean scores of pain severity were reduced by 39.46% and by 6 hours, there was a further 52% reduction in the mean scores. Therapy with intravenous lornoxicam was associated with a faster onset of action with 15.4% patients reporting pain relief within 10 minutes and 55.9% patients within 10 to 30 minutes. Overall, global assessment of efficacy was rated as good to excellent in 95.3% of the patients. Therapy with intravenous lornoxicam was well tolerated with only 5 patients reporting adverse events such as headache (n=3) and gastritis (n=1) of mild to moderate intensity but transient. Overall, global tolerability was rated as good to excellent in 98.4% of the total cases and fair in only 1.6% of the cases. In conclusion, the results of the present study indicate that intravenous lornoxicam is a potent NSAID with an optimal efficacy/toxicity ratio and thus could be a suitable therapeutic option in the management of patients with painful traumatic conditions requiring parenteral NSAIDs and hospitalisation.

Results of a comparative, phase III, 12-week, multicenter, prospective, randomized, double-blind assessment of the efficacy and tolerability of a fixed-dose combination of telmisartan and amlodipine versus amlodipine monotherapy in Indian adults with stage II hypertension.

OBJECTIVE: The aim of this study was to evaluate the efficacy and tolerability of a new fixed-dose combination (FDC) of telmisartan 40 mg + amlodipine 5 mg (T+A) compared with amlodipine 5-mg monotherapy (A) in adult Indian patients with stage II hypertension. METHODS: This comparative, Phase III, 12-week, multicenter, prospective, randomized, double-blind study was conducted in Indian patients aged 18 to 65 years with established stage II hypertension. Patients were treated with oral FDC of T+A or A QD before breakfast for 12 weeks; blood pressure (BP) and heart rate were measured in the sitting position. Primary efficacy end points were reduction in clinical systolic BP (SBP)/ diastolic BP (DBP) from baseline to study end and number of responders (ie, patients who achieved target SBP/ DBP <130/<80 mm Hg) at end of study. Tolerability was assessed by treatment-emergent adverse events, identified using physical examination, laboratory analysis, and electrocardiography. RESULTS: A total of 210 patients were enrolled in the study; 203 patients (143 men, 60 women) completed the study while 7 were lost to follow-up (4 patients in the T+A group and 3 in the A group) and considered with-drawn. At study end, statistically significant percentage reductions from baseline within groups and between groups were observed in SBP (T+A [-27.4%]; A [-16.6%]) and DBP (T+A [-20.1%]; A [-13.3%]) (all, P < 0.05). Response rates were 87.3% (89/102) in the T+A group and 69.3% (70/101) in the A group (P < 0.05). The prevalences of adverse events were not significantly different between the 2 treatment groups (T+A, 16.0% [17/106]; A, 15.4% [16/104]). Peripheral edema was reported in 8.5% patients (9/106) in the T+A group compared with 13.5% (14/104) in the A group, and cough was reported in 3.8% patients (4/106) in the T+A group and 1.0% (1/104) patients in the A group; these differences did not reach statistical significance. The incidences of headache, dizziness, and diarrhea were similar between the 2 groups. CONCLUSIONS: Among these Indian patients with stage II hypertension, the FDC of T+A was found to be significantly more effective, with regard to BP reductions, than A, and both treatments were well tolerated.

Evaluation of the efficacy, safety and tolerability of miglitol in adult Indian patients with uncomplicated type 2 diabetes mellitus.

Postprandial hyperglycaemia and spikes have deleterious effects on Insulin secretion and sensitivity. The present study was undertaken to evaluate the efficacy, safety and tolerability of miglitol 50 mg three times daily for 12 weeks in 129 patients with type 2 diabetes mellitus, inadequately managed with diet and exercise therapy alone for 3 months after obtaining their written informed consent. The primary efficacy variables were per cent change from baseline at week 12 in fasting and postprandial plasma glucose concentrations and glycosylated haemoglobin (HbA(1C)) levels. After treatment at the end of 12 weeks mean reduction in fasting plasma glucose levels was 35.7% and 44.33% in postprandial plasma glucose levels while the mean HbA(1C) was significantly reduced by 0.88% (p<0.05). Total cholesterol, HDL, LDL and TC/HDL ratio did not showed any significant change but a non-significant reduction in triglyceride levels was observed in some patients. The mean body mass index was reduced non-significantly by 8% from baseline values. A total 19.5% patients treated with miglitol reported adverse events like flatulence, abdominal pain, nausea/vomiting, diarrhoea and dyspepsia. Only one patient reported hypoglycaemia. The results of the present study indicate that miglitol reduces fasting and postprandial plasma glucose levels, Improving glycaemic control, which is reflected in a reduced HbA(1C) level in patients with type 2 diabetes mellitus. It could be a useful first-line therapy in patients with type 2 diabetes mellitus inadequately controlled by diet alone and as adjuvant therapy in patients who are inadequately controlled with diet and sulfonylureas.

Levofloxacin in enteric fever--a study.

Typhoid fever is an important cause of morbidity and mortality in patients especially in developing country. Therapy with conventional drugs is associated with increasing resistance, non-compliance to therapy and toxicity. Oral fluoroquinolones have been shown to be effective compared to parenteral broad-spectrum cephalosporins in the treatment of uncomplicated typhoid. However, there is no data available regarding the use of levofloxacin in the treatment of typhoid fever in spite of the susceptibility of Salmonella species to levofloxacin. The present study was undertaken to evaluate the efficacy, safety and tolerability of oral levofloxacin 750 mg once daily in the treatment of typhoid fever. Results indicated that levofloxacin 750 mg administered orally once daily was an effective, safe, well-tolerated and cost-effective option in the treatment of typhoid fever in adult Indian males and non-pregnant females.

Comparative assessment of the bioavailability, efficacy and safety of a modified-release (MR) carbonyl iron tablet and oral conventional iron preparation in adult Indian patients with nutritional iron deficiency anaemia.

The objective of the study is to evaluate the bioavailability, efficacy and safety of a new modified-release (MR) formulation of carbonyl iron (45 mg) relative to a commercially available conventional formulation of ferrous fumarate (300 mg) in adult Indian patients with clinical and laboratory diagnosis of nutritional iron deficiency anaemia. This prospective, comparative, randomised, double-blind study was carried out among 60 patients received a single daily dose of either MR carbonyl iron or ferrous fumarate for 12 weeks. The effect of therapy on haematological parameters and iron status and estimation of bioavailability were the main efficacy outcomes. There was a significant (p<0.05) increase in mean haemoglobin levels, reticulocyte counts, haematocrit and mean corpuscular volume in MR carbonyl iron group compared to ferrous fumarate group. There was also an increase in mean serum iron and ferritin levels and a corresponding decrease in total iron binding capacity in MR carbonyl iron group compared to ferrous fumarate group at the end of 12 weeks therapy. The estimated overall bioavailability of MR carbonyl iron was about 147% that of ferrous fumarate. Both the formulations were equally well-tolerated and adverse events were mainly gastrointestinal in nature. The prevalence of adverse events was slightly more in the ferrous fumarate group. It can be concluded that the MR formulation of carbonyl iron was more efficacious than ferrous fumarate in correcting haematologic abnormalities and improving iron status in patients with nutritional iron deficiency anaemia. In conditions where efficacy is an important consideration, the higher bioavailability of MR carbonyl iron may make it the treatment of choice for nutritional iron deficiency anaemia.

A pilot study for evaluation of the efficacy and safety of telmisartan in reducing microalbuminuria in hypertensive patients with type 2 diabetes mellitus.

To evaluate efficacy and tolerability of telmisartan, an angiotensim II receptor blocker, in reducing microalbuminuria in adult Indian hypertensive patients with type 2 diabetes mellitus, a prospective, open-label, non-comparative, assessor-blind, multicentric, pilot study was conducted in 60 eligible hypertensive patients with type 2 diabetes mellitus and microalbuminuria after obtaining their informed consent. The study was approved by the respective institutional review boards. Each patient received telmisartan 40 mg initially once daily for first 4 weeks which was titrated upwards to 80 mg once daily for the next 8 weeks. Blood pressure was assessed at the end of every 2 weeks and urinary albumin excretion and creatinine clearance were measured at baseline and after 12 weeks of therapy. Safety outcome measures included monitoring of physical examination, laboratory parameters and monitoring treatment-emergent adverse events. Fifty-five patients completed the study while 5 cases were lost to follow-up. The mean age of the patients was 48.27 years. Of the total patients 63.6% were males and 46.4% were females. At baseline the mean urinary albumin excretion rate was 131.81 +/- 38.82 mg/minute. A statistically significant (p < 0.05) reduction (32.96%) in urinary albumin excretion rate occurred after 12 weeks of therapy (118.36 +/- 37.22). The mean pre-study systolic blood pressure was 165.05 +/- 15.24 mmHg which was significantly (p < 0.05) reduced to 123.72 +/- 5.88 mmHg at the end of 12 weeks. At baseline the mean diastolic blood pressure was 103.55 +/- 9.84 mmHg which was significantly (p < 0.05) reduced to 84.71 +/- 8.54 mmHg. The JNC-VII goal of blood pressure below 130/80 was achieved in 34 (61.8%)of the 55 patients at the end of 12 weeks. Both fasting and postprandial blood sugar levels were well-controlled at the end of the study. Telmisartan was well tolerated with only 9.09% of the patients reported mild and transient adverse events like fatigue, dizziness, nausea and diarrhoea. No abnormalities were detected in the laboratory parameters. The results of this pilot study indicate that telmisartan is effective, safe and well tolerated while reducing microalbuminuria in adult Indian hypertensive patients with type 2 diabetes mellitus.

Effects of oral fixed-dose combinations of telmisartan plus ramipril and losartan plus ramipril in hypertension: A multicenter, prospective, randomized, double-blind, phase iii trial in adult indian patients.

BACKGROUND: A new oral fixed-dose combination (FDC) of telmisartan plus ramipril is being introduced in India for the treatment of patients with stage 2 hypertension. OBJECTIVE: The aim of this study was to compare the effectiveness and tolerability of an oral FDC of telmisartan plus ramipril with those of an oral FDC of losartan plus ramipril in adult Indian patients with stage 2 hypertension. METHODS: This multicenter, prospective, randomized, double-blind, Phase III study was conducted at 5 centers in India. Indian patients aged 18 to 65 years with uncomplicated stage 2 essential hypertension (systolic/diastolic blood pressure [SBP/DBP], >160/>100 mm Hg) were enrolled. After a 2-week placebo run-in period, patients were randomly assigned to receive telmisartan 40 mg plus ramipril 5 mg (T + R) or losartan 50 mg plus ramipril 5 mg (L + R), PO (tablet) QD (before the morning meal) for 8 weeks. Supine blood pressure (BP) was measured at 0 (baseline) and 8 weeks of treatment. The primary end point was the mean reduction from baseline in BP. Responders were classified as patients who had a DBP <90 mm Hg at the end of 8 weeks of therapy. Tolerability was assessed using spontaneous reports of adverse events (AEs) during the follow-up visits and laboratory analyses performed at week 8. RESULTS: A total of 289 patients were enrolled (155 men, 134 women; mean age, 50.74 years). Of these, 8 patients in the T + R group and 7 in the L + R group were lost to follow-up and considered withdrawals. At the end of week 8, the mean percentage reduction in SBP was significantly greater in the T + R group compared with that in the L + R group (24.1% vs 19.4%; P < 0.05). The mean percentage reduction in DBP was also significantly greater in the T + R group compared with that in the L + R group (17.3% vs 12.5%; P < 0.05). The response rates in the T + R and L + R groups were statistically similar (79.1% vs 68.7%). The most common AEs in the T + R and L + R groups were cough (9 [6.1%] and 11 [7.8%] patients, respectively) and headache (7 [4.7%] and 8 [5.7%] patients, respectively). CONCLUSIONS: The results in this study in Indian patients with stage 2 essential hypertension suggest that the FDC of T + R controlled BP more effectively compared with the FDC of L + R over 8 weeks. The response rates were similar between the 2 groups. Both treatments were well tolerated.

Comparison of the effects of parecoxib and diclofenac in preemptive analgesia: A prospective, randomized, assessor-blind, single-dose, parallel-group study in patients undergoing elective general surgery.

BACKGROUND: Preoperative administration of analgesics may prevent or reducehyperalgesia, inhibit inflammation, and reduce pain by reducing the synthesis of prostaglandins in response to tissue damage caused by surgery. Nonsteroidal anti-inflammatory drugs (NSAIDs) are a potent, widely used class of analgesic agents; however, they may not be as effective as selective cyclooxygenase (COX)-2 inhibitors. OBJECTIVE: The aim of this study was to compare the efficacy and tolerabilityof the COX-2 inhibitor parecoxib sodium and the NSAID diclofenac sodium as preemptive analgesics in patients undergoing elective general surgery. METHODS: This was a prospective, randomized, assessor-blind, single-dose,parallel-group, comparative trial. Patients aged 18 to 65 years undergoing elective general surgery were enrolled. A single IM injection of parecoxib 40 mg or diclofenac 75 mg was administered 30 to 45 minutes before the induction of anesthesia. Surgery was performed as per standard protocol. The primary measures of efficacy were pain intensity score (measured on a visual analog scale [VAS]), pain relief score, duration of analgesia, and platelet aggregation response to adenosine diphosphate. Tolerability assessment included monitoring of treatment-emergent adverse events (AEs), physical examination, laboratory analysis, electrocardiography, and chest radiography. RESULTS: Eighty patients (56 men, 24 women; mean [SD] age, 45.96 [12.83] years) were enrolled in the study (40 patients per treatment group). All patients completed the trial. No pain was reported by any patient in the parecoxib group up to 12 hours; in the diclofenac group, no pain was reported up to 6 hours. At 12 hours, the mean (SD) VAS score was 2.33 (1.39) (moderate pain) in the diclofenac group and 0 (no pain) in the parecoxib group (P < 0.05). At 12 hours, total pain relief was reported by all 40 patients (100.0%) in the parecoxib group but by none (0.0%) in the diclofenac group, and 2 patients in the diclofenac group (5.0%) reported good pain relief (between-group difference for total + good pain relief, P < 0.05). Mean (SD) duration of analgesia was significantly longer in the parecoxib group than in the diclofenac group (19.48 [5.61] hours vs 8.32 [4.11 ] hours; P < 0.05). Platelet aggregation was significantly inhibited in the diclofenac group (change from baseline, 64.0%) but not in the parecoxib group (change from baseline, 12.0%) (P < 0.05). Both regimens were well tolerated, and no AEs were reported. CONCLUSIONS: In this study of patients undergoing elective general surgery,patients treated with the COX-2 specific inhibitor parecoxib experienced no pain at 12 hours, and the treatment was well tolerated. The results of this study suggest that good postoperative analgesia and minimal interference with platelet function may make parecoxib an alternative to the nonselective NSAID diclofenac in providing preemptive analgesia in patients undergoing general surgery.
