ABSTRACT

Free radicals are partially reduced form of metabolites of Nitrogen and Oxygen. These are highly reactive and potentially toxic compounds which are contributing factors in different chronic disease. The present study was aimed to determine antioxidant capability and reducing ability of coded polyherbal capsules [Arthitec 1 and Arthitec 2]. DPPH [2,2'-diphenyl-1-picryl hydrazyl] assay is most commonly used method for gauging antioxidant capability of natural compounds. In this assay DPPH act as stable free radical which react with an antioxidant. For measuring reducing ability suspected antioxidant react with ferric tripyridyltriazine [Fe3 +/- TPTZ] complex and convert ferric into ferrous. Results are evident that both capsule formulations Arthitec 1 and Arthitec 2 have promising antioxidant activity and reducing potential. Antioxidant potential of both coded capsules with varied concentrations [10, 50 and 100 microg/ml] were compared and in both cases scavenging activity and as well as reducing ability raised in a dose dependent manner just like standard Butylated hydroxyanisole [BHA]

ABSTRACT

The contemporary work describes a rapid and cost effective reversed phase High Performance Liquid Chromatography [RP-HPLC] method for the quantification of Captopril, Lisinopril and Dexibuprofen [DXP] simultaneously in dosage formulations, active pharmaceutical ingredients and human serum. The chromatographic system included LC-20A pump, Sil-20A auto sampler and SPD-20A UV/visible detector. The estimation was carried out by using a C[18] [5micro m, 250 ×4.6 mm] column with mobile phase methanol: water [80:20 v/v, pH 3.0] at 230 nm with a flow rate of 1.0 ml·min[-1]. The retention time of Dexibuprofen was 5.4 min while that of Captopril and Lisinopril were found to be 3.2 and 1.8 minutes respectively. There was no considerable variation exists in between the tested drug spiked in serum and the extent recovered, without interference of serum in concurrent approximation. The method developed was found to be precise, selective and validated for precision, linearity, specificity, accuracy, limit of detection and limit of quantitation. There is no such method reported earlier for the determination of ACE Inhibitors and DXP simultaneously. The present study helps in assessing the co-administration of both drugs in treatment and can be employed for quality control analysis and drug-drug interaction studies

ABSTRACT

Antioxidants are used as an influential counteractive measure in opposing the generation of reactive oxygen species. The current study was carried out to investigate antioxidant potential and reducing capability of developed weight reducing tablet formulation. When tablets were evaluated at concentrations of 50, 100 and 500 micro g/ml, antioxidant activity improved in a dose depending way just similar to standard Butylated hydroxyl anisol [BHA]. For evaluation of reducing ability the formulation under test evaluated at concentrations of 50, 100 and 500micro g/ml and it was observed that formulation contain good reducing capability and possess considerable activity to scavenge super oxide radicals. In-vitro analysis of weight reducing tablets formulation showed considerable antioxidant and reducing capacity that will be supportive in averting the development of a variety of oxidative stress-related diseases

ABSTRACT

The current randomized clinical trial was conducted to assess the safety and effectiveness of Entoban for treating patients of chronic diarrhea. The study enrolled 150 patients fulfilling the inclusion criteria, among them 95 were males and 55 were females. Written informed consent was obtained from all study participants. Metronidazole tablets [400 mg] were used in a control group for 7-10 days. The test group received Entoban capsule 400mg every 8 hours for five days. Primary outcome of the study was daily bowel frequency evaluation; the secondary outcome was evaluation of clinical symptoms including abdominal pain, distention, stool consistency and sensation of incomplete evacuation. The study is registered at [https://register.clinicaltrials.gov] having registration number NCT02642250. In an intention-to treat [ITT] analysis, it has been observed that 39[84.78%] in test group and 37[78.72%] in control group showed complete improvement. Participants in the test group exhibited a marked reduction in symptoms; the symptom score was decreased from 3 [maximum] to 1 [minimum] or 0 [absent] in most of participants. Major difference was observed regarding side effects reported between two treatment groups [p value <0.0001]. Entoban possesses considerable therapeutic efficacy for the treatment of chronic diarrhea analogous with the conventional Metronidazole therapy

ABSTRACT

In this study, occurrence of adverse drug reactions in female patients receiving chemotherapy were analyzed. Various drugs prescribed for cancer patients for compensation of these adverse reactions were also noted. Study was conducted on 83 female cancer patients selected randomly from a recent record of six months in KIRAN [Karachi Institute of Radiology and Nuclear Medicine] hospital, Karachi, Pakistan. Only those cases were selected in which patients received at least three cycles of cancer chemotherapy. The collected reports were analyzed for patients' data, drug details, causality, preventability and severity of adverse effects. Causality was assessed by the World Health Organization [WHO] causality assessment scale. Preventability and severity of ADRs were assessed by Naranjo's Algorithm and modified Hartwig's and Siegel scale. Out of n=83 females, n=55 [66.26%] females were married. Majority belonged to lower socioeconomic class [n=64, 77.10%]. In the 40-49 years age group 30.12% [n=25] adverse drug reactions [ADRs] were seen whereas 26.50% [n=22] ADRs in 50-59 years of age and 25.30% [n=21] ADRs in 30-39 years of age group were observed. The cases observed were of breast cancer [n=52, 62.65%], ovarian cancer [n=l4, 16.86%], Gl Cancer [n=8, 9.63%], and others that include head and neck cancer [n=3, 3.61%], lymphomas [n=3, 3.61%], sarcomas [n=2, 2.40%] and mass on chest wall [n=l, 1.20%]. In general, the common adverse effects observed were neutropenia/pancytopenia/anemia [n=64, 77.10%], alopecia [n=51, 61.44%], nausea and vomiting [n=39, 46.98%], fatigue/anorexia [n=26, 31.32%], mouth sores [n=21, 25.30%], fever and chills [n=20, 24.09%] and diarrhea [n=12, 14.45%]. According to the three scales employed for ADRs assessment i.e. [WHO] causality assessment scale, Naranjo's Algorithm and modified Hartwig's and Siegel scale for preventability and severity of ADRs, the results are in close agreement with each other with respect to occurrence and severity of the ADRs. A number of ADRs are observed in various cancer patients receiving chemotherapy indicating high need of ADR monitoring and reporting. The problem of under-reporting of ADRs is a big issue and must not be overlooked
