RESUMO
Background: Asthma is a chronic disease that affects approximately 300 million people worldwide. Tectona grandis Linn. bark, also known as Teak (English), is traditionally used to treat asthma. However, the scientific data on anti-asthmatic and anti-cholinergic of this plant has got little attention. An attempt has been based on ethanolic extract of bark of Tectona grandis Linn. shown a tremendous effect on asthma when comparative study was done with normal and treated group.Methods: The anti-asthmatic activity of a 95% ethanol and 5% distilled water extract of dried and fresh Tectona grandis Linn. bark, was evaluated against histamine and acetylcholine-induced preconvulsive dyspnea (PCD) in guinea pigs fasted for 24 h were exposed to an atomized fine mist of 2% histamine dihydrochloride and acetylcholine aerosol (dissolved in normal saline) using nebulizer at a pressure of 300 mmHg in the histamine chamber (24�� cm, made of perplex glass. They were divided in groups Mepyramin (8 mg/kg) intraperitonially, atropine aerosol and Tectona grandis bark formulation (2.5, 5, 10 gm/kg) were administered orally 30 min prior to exposure. Animals, which did not develop typical asthma within 6 minutes, were taken as protected.Results: Ethanolic extract of Tectona grandis Linn. bark at 5 and 10 gm/kg significantly reduce bronchoconstriction as compared to control group along with significant mast cell stabilization activity.Conclusions: In conclusion, the present study shows that the ethanolic bark extract of Tectona grandis Linn. has potential antiasthamatic and antichlolinergic action in histamine and acetylcholine broncocontraction in guinea pigs.
RESUMO
Background: The overall prevalence for hypertension in India was estimated to be 29.8%. Patient’s optimal adherence with antihypertensive drug therapy is essential for preventing serious complications with hypertension over the long term. Therefore, the present study was undertaken to evaluate the prescription pattern of the drugs prescribed to hypertensive patients.Methods: Present study was a prospective cross sectional observational study carried out in the outpatient of department of general medicine of MGM Hospital, a tertiary care teaching hospital, in Aurangabad. Prescriptions of 120 diagnosed hypertensive patients were analysed. Data was recorded as mean±standard deviation.Results: The mean age of the patients was 57.13±10.94 years with range 18-80 years. 82.5 % (99) of patients were male and 17.5% (21) of patients were female. Mean duration of hypertension was 3.97±2.55. Most of the patients 57 (47.5%) were on Mono therapy significantly higher than dual therapy, triple therapy and poly therapy, 39 (32.5%), 15 (12.5%), 9 (7.5%) respectively. Calcium channel blocker was the frequently used class of drug for monotherapy (20%). Polytherapy was seen in 7.5% patient. Among 120 patients’ only 37 patients were reported ADR. Maximum no of ADRs were reported from patients receiving ACE inhibitor.Conclusions: This type of studies gives the base line idea of prescription pattern and ADRs of antihypertensive drugs. These help to design policy for rational use of drugs and motivation of physician for rational use of drugs.
RESUMO
Background: Hypertension with dislipidemia is becoming a common morbidity, since ACE inhibitors are the first line of antihypertensive drugs so present study was undertaken with the aim to evaluate the possible effects of ACE inhibitor on lipid profile in albino rabbits.Methods: The study was conducted in the Department of Pharmacology and Therapeutics, GSVM Medical College, Kanpur. Rabbits were divided into 2 groups with 6 in each group. Rabbits of Group I was given Lisinopril in dose of 0.25mg/kg and of group II was given Perindopril in dose of 0.20mg/kg for a period of 6 weeks. Lipid profile estimation (Serum Total cholesterol, serum HDL, serum LDL, serum Triglycerides and serum VLDL) was done at day 0, 7, 21 and 45 respectively.Results: After analysis Rabbits of group-I (Lisinopril) showed 3.1% decrease in serum cholesterol level at 45th day (P<0.001). Serum HDL level increased by 6.4% and 14.3% at day 21 and 45 respectively (P<0.05). Increase in serum Triglyceride level was 2.6% at day 45 (P>0.05). Serum LDL level decreases by 4.4% and 8.6% at day 21 and 45 respectively (P<0.001). There was no significant change in Serum VLDL level. Rabbits of group- II (Perindopril) showed decreased total cholesterol levels by 2.6% (P<0.05). There was an increase in HDL level by 6.8 % at day 45(P<.05). Triglycerides and VLDL levels were not significantly altered while serum LDL level decreases by 6.7% at day 45 (P<0.01).Conclusions: From our study it was concluded that Lisinopril had a favourable effect on serum lipid profile by decreasing total cholesterol, increasing serum HDL level. It may increase triglycerides, decrease LDL. Perindopril increase serum HDL and decreases LDL, there is no significant change in cholesterol, TG and VLDL levels.
RESUMO
Background: Management of pain is a primary clinical concern for any pathology in medical field. Addiction liability of opioids and troublesome gastrointestinal side effects of NSAIDs leads to intensive research for compound with lesser side effects.The aim of the study to evaluate the anti-nociceptive activity of Acacia Tortilis Seed Extract (ATE) in experimental animals.Methods: First of all, animals were randomly allocated into four groups of six animals each. In acetic acid induced writhing test model, Group I (NC) served as vehicle control received saline/Tween 80 0.1%, 10ml/kg BW orally, group II (ATE-100) and III (ATE-200) received ATE in dose of 100 and 200mg/kg BW orally respectively and group IV received the standard drug diclofenac sodium in dose of 50 mg/kg BW orally. Group I to IV were same in rest of three experimental models. One additional group of standard drugs (group V) morphine sulfate in dose of 5 mg/kg BW subcutaneously (SC) was allocated for screening method hot plate and tail flick tests. In Formalin induced paw licking test, three additional groups (group V) morphine sulfate in dose of 5mg/kg BW SC, group VI- morphine+naloxone (5mg/kg SC +2mg/kg intra-peritoneally (IP) and group VII - ATE+ naloxone (200mg/kg BW orally +2mg/kg BW IP) were also made.Results: The ATE when administered orally in dose of 100 and 200mg/ kg body weight (BW), produced significant analgesic activity (P <0.01) in acetic acid induced writhing syndrome and late phase of formalin test. In the hot plate test in mice and tail flick test in rats, ATE in same doses also showed significant analgesic activity (P <0.05) which is almost equally efficacious to standard drug diclofenac sodium (50mg/kg BW orally) but far less efficacious than morphine sulfate (5mg/kg BW subcutaneous).ATE (200mg/Kg BW orally) activity did not blocked by naloxone (2mg/kg intra-peritoneal).Conclusions: ATE possesss significant anti-nociceptive activity as evidenced in all the animal models of nociception. It might exert its effect through the peripheral mechanism of analgesic action possibly by interference in biosynthesis, release and/or action of prostaglandins and leukotrienes.
RESUMO
Background: Drug utilization studies (DUS) are used as potential tool in the evaluation of healthcare system. DUS are conducted to facilitate the rational use of drugs in populations. The indicators of prescription in practice measure the performance of health care provider in several key dimensions related to appropriate use of drug. Therefore, the present study was undertaken to analyze the prescription written by doctors in a Tertiary Care Hospital in rural area.Methods: Present study is a cross sectional, prospective and observational study. The study was conducted in a rural tertiary, teaching hospital at JIIU’s Indian Institute of Medical Science and Research, Warudi, Taluka Badnapur from January 2017 to September 2017 for duration of 9 months. Data was obtained from 300 prescriptions. Data was analysed as per WHO prescribing indicators.Results: Average number of drugs in the present study was found to be 2.85. Percentage of drugs prescribed by generic name is 13.48%. Percentage of encounters with an antibiotic prescribed 60%. Percentage of encounters with an injection prescribed 4.33%. Percentage of drugs prescribed from essential drugs list 72.91%.Conclusions: These types of studies help to design policy for rational use of drugs and motivation of physician for rational use of drugs.
