RESUMO

National diseases burden of Cardiovascular diseases is the top leading cause of death in Pakistan. In this study, Pakistani has been assessed for Atherosclerotic Cardiovascular Disease (ASCVD) on the basis of American Herat Association (AHA) guidelines. The aim of the study is to assess and inform about 10-year risk and life time risk in people residing in the largest metropolis city Karachi and aware about the use of statins as per revised Pooled Cohort Equation guidelines. The study sample size was 1760 with the age of 39 to >80 years with non-atherosclerotic diseases. Both genders without language barrier with or without elevated lipid were included. Clinical investigations including HDL, B.P and serum TG were included for calculating the ten year and life time risks on the basis of <5%, 5-7% and >7.5%. Results shows that the Odd ratio >1 found between age and TC however significant relationship (p<0.05) between gender, diabetes, hypertension and smokers were established. >50% study population required moderate and high intensity statin however <30% needed life style modification for reducing cardiac on risk. It is concluded that current recommendations are not for South Asians and may under or overlook the risks of individuals living in this continent. This study estimates the cardiovascular risk burden in the population of Karachi, Pakistan who were non-atherosclerotic undiagnosed and un-treated. This risk assessment may modify the algorithm and successfully identify the risk burden in present study groups.

RESUMO

Cough is the common disease condition which affects patients of every age. Numerous OTC medications available in community pharmacies however no antiviral treatment and even antibiotics has been shown to be effective without pre-existing lung infection. The treatment approach of medicinal herbs has been recognized for many decades and even longer for the treatment and prevention of cough. The aim of this study was to evaluate the safety and efficacy of Mukalbion poly herbal chewable tablets for the treatment of cough with improved palatability against a marketed brand (Poly herbal). For the formulation development of test group, the herbs were supplied by the Procurement department of Herbion Pakistan Pvt. Ltd. Althea officinalis (roots), Hedera helix (leaves) and Sisymbrium irio (seeds) were used for the manufacturing of Mukalbion (poly herbal, test group) chewable tablet. The comparative control clinical trial was carried out during a time frame of 07 months with sample size of 70 patients as per epidemiological software for sample size and each group contained 35 (±5) patients. Chewable tablets were administered and evaluated for effectiveness after 15 days of treatment. The data were collected by the patients through clinical trial questionnaire. The validated quality of life questionnaire (LCQ) was also used for assessment. The results were analyzed by applying paired sample T test by using IBM SPSS version 20.00. The p value was <0.005 at 95% confidence interval for cough variables including cough bouts, viscosity of sputum, chest congestion, sore throat and shortness of breath. The LCQ cough scale score was higher in test group as compared to control group. The test group also showed well tolerated in term of palatability. None of the patient claimed any of the side effects and no compliance were observed against the marketed brand.

RESUMO

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 C18 (5µm, 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.

RESUMO

To estimate the effects of using hormonal contraceptives on serum lipoprotein levels. Lipid profile was measured at baseline and afterward at 3, 6, 9 and 12 months. 1391 Pakistani females taking COCs, DMPA, or non hormonal (NH) contraceptives. The results were calculated by repeated measure ANOVA subsequent to tukey's post hoc test for the multiple comparisons. Statistical examination revealed that differences in lipid profile were significant (p <0.001) among all treated group in comparison with control. DMPA also caused significant rise in Castelli index-I and Castelli index-II as compared to COCs group and control group. This study demonstrated raise in total cholesterol (TC) and triglycerides (TG) as well as very low density lipoprotein (VLDL-C) and low density lipoprotein cholesterol (LDL-C). Whereas, an obvious decrease was observed in high density-lipoprotein cholesterol (HDL-C) in the DMPA-treated group. We concluded that, this inductive study specifies atherogenic cardiovascular risk in women using DMPA on long term basis.

RESUMO

Type 2 diabetes mellitus (T2D) is a chronic metabolic disease regarded as insulin resistance and progressive failure of ß cells. Beta cells secretagogues are useful to reach satisfactory glycemic control. Glimepiride is a second-generation sulfonylurea excites pancreatic beta cells to discharge insulin. Glimepiride may be safer to use in patients with cardiovascular disease due to lack of destructive effects on ischemic preconditioning. It is effective in dropping fasting plasma glucose (FPG), postprandial glucose and glycated hemoglobin levels and is a useful and cost-effective option treatment for the management of T2D. Total 40 patients were selected from OPD setting at RSNPMTS Endocrinology center Ministry of Health Republic of Uzbekistan, and corresponding to criteria for inclusion / exclusion. 10 patients with T2D switched from receiving other forms of Glimepiride (Amaryl) on an identical dose of GlucoNovax in combination with biguanides (Metformin) denoted as group 1. At the same time the dose of biguanides (Metformin) was not altered for the period of the study. 10 patients with T2D switched from receiving other forms of Glimepiride (Amaryl) on an identical dose of GlucoNovax denoted as group 2.10 patients with T2D switched to the drug GlucoNovax from the drug Glibenclamide denoted as group 3. The control group received monotherapy with Amaryl it consist of 10 patients with T2D denoted as group 4. The severity of diabetic complaints in patients receiving the combination drug GlucoNovax with metformin significantly decreased by the end of the observation period and had an inclination to reduction in the 2nd and 3rd groups, along with the control group. 30 patients, receiving the drug Gluco Novax, 7 achieved blood glucose level parameters that corresponding to the high effectiveness of the drug (4 of them from 1st group (GlucoNovax+ Metformin), 1 in the 2nd group, 2 in the 3rd group). 6 patients achieved blood glucose levels parameters, meeting the criteria of moderate effectiveness of the drug (4 of them from 1st group, 1 patient in the 2nd and 1 patient in the 3rd groups). The given result may be, associated with initially high levels of compensation of carbohydrate metabolism, as well as a more effective influence on combination treatment with Metformin. The drug GlucoNovax appears to be an effective hypoglycemic agent in the treatment of T2D with good tolerability.

RESUMO

Introduction: Cancer, particularly breast cancer, is a major contributor to mortality and a significant impediment to life expectancy. In 2020, breast cancer accounted for 11.7% of all cancer cases and caused approximately 685,000 deaths worldwide, surpassing lung cancer in prevalence. The study aims to evaluate the impact of an educational intervention on breast cancer awareness among pharmacy students by comparing their understanding before and after the program. Method: A pre-post quasi-experimental study was designed to assess knowledge and awareness of breast cancer, breast self-examination (BSE) practices, and attitudes toward breast cancer among female university students in Karachi, Pakistan. Participants completed a pre-session questionnaire, attended an awareness workshop and video tutorial, and then completed a post-session questionnaire 2 weeks later. Results: Of 1,200 participants, 1,015 of them completed both the pre- and post-intervention questionnaires. Key demographic features included 83.9% of the participants being in the 18-24 age group, 26.8% being married, and only 14.2% having a family history of breast cancer. Before the intervention, 60.7% of the participants were not involved in regular breast self-exams due to a lack of awareness. Post-intervention results showed a significant increase in awareness, with 35.9% rising to 94.9%. The use of screening methods increased from 46.7 to 94.8%. Knowledge of breast cancer improved from 51.2 to 96.7%, and the general perception rose from 48.2 to 93.4%. Attitudes toward self-examination also shifted positively, indicating a significant change in perception. Interpretation and conclusion: The study concludes the baseline knowledge of breast cancer among female students was inadequate but improved significantly from over 40% to over 90% following the educational intervention. The intervention positively influenced the general perception and attitudes toward breast cancer. These findings highlight the need for regular educational sessions to enhance awareness, improve healthcare outcomes, and reduce mortality rates, particularly in developing countries.

RESUMO

Barley scientifically known as Hordeum vulgare (HV) is a major grain crop. Over the course of time, great interest has been developed in the usage of barley, because of its various pharmacological activities. Current study is designed to determine the chemical constituents of Hordeum vulgare (HV) seed extract by GC-MS technique, and Invitro antioxidant assays i.e. 1,1-diphenyl-2-picryl-hydrazyl free radical (DPPH) and 2-azino-bis(3-ethyl benzthiazoline-6-sulfonic acid) (ABTS) methods. GC-MS identified 16 non-polar compounds in the hexane extract of HV plant, which includes carboxylic acid (6.25%), fatty acid (37.5%), carboxylic acid amide derivative of fatty acid (6.25%), triterpinoids (18.75%), fat soluble vitamin (6.25%), phytosterol (6.25%), stigmastanes (6.25%), beta diketones (6.25%), and cycloartenol (6.25%) respectively. The major compound includes Hexadecanoic acid, methyl ester (6.84%), n-Hexadecanoic acid (8.58%), 9,12-Octadecanoic acid (Z,Z)-, Methyl Ester (8.04%), 9,12-Octadecadienoic acid (Z,Z) (57.01%), Lup-20(29)-en-3-one (3.57%), γ-Sitosterol (3.31%). Some constituents such as Lup-20(29)-en-3-one, campesterol and squalene were observed and were not previously reported. Total phenolic and total flavonoid content were determined using spectrophotometric technique and calculated as gallic acid equivalents GAE/g dry weight and rutin equivalent RE/g of dry weight respectively.The highest phenolic content exhibited by the acetone extract of HV seedsi.e. 0.0597 mg GAE/g while the highest flavonoid content exhibited by dichloromethane extract i.e. 0.09 mg RE/g and 0.25 mg QE/g of dry weight respectively. All the extracts showed significant antioxidant activity in DPPH and ABTS cation decolorization assays. Methanol and dichloromethane extract showed the highest DPPH radical scavenging activity i.e. 52.41% and 42.07% at the concentration of 100 mg/ml respectively. Moreover, the IC50 has been determined by the acetone and methanol extract of HV seeds. The high antioxidant activity of its seed extracts has made this plant pharmacologically important. Conclusively, there is a vast scope to further explore the active principals of barley so that more of its pharmacological properties can be identified.

Current study has been planned to determine chemical constituents of basil leaves extracts and their in-vitro and ex-vivo antioxidant and in-vivo antihypertensive potential. GC-MS studies of non-polar extracts showed presence of 75 compounds including monoterpenes, hydrocarbons, sesquiterpenes, triterpenes, phyto-sterols and phthalates. Higher percentages of fatty acids were also identified. The major compounds include linalool (7.65%), terpineol (1.42%), tau-cadinol (13.55%), methyl palmitate (14.24%), palmitic acid (14.31%), linolenic acid (1.30%) and methyl linolenate (17.72%). Electron spray ionization mass spectrometry ESI-HRMS/MS of the polar extracts revealed the presence of alkaloids, phenolic acid, amino acid, coumarin, lignin, flavanoid and terpene derivative. Total phenolic content and total flavonoid content were determined using spectrophotometric technique and calculated as gallic acid equivalents GAE/g dry weight and rutin equivalent RE/g of dry weight respectively. The highest phenolic content and flavonoid content were found in ethyl acetate extract 9.40 mg GAE/g and 15.9 mg RE/g of dry weight. All the extracts showed significant antioxidant activity in DPPH and ABTS cation decolorization assays. Dichloromethane extract possess the highest DPPH scavenging activity, i.e., 64.12% ± 0.23 at concentration of 4 mg/ml. Moreover in ex-vivo studies all the extracts showed prominent effect by inhibiting AAPS induce oxidation in Human erythrocytes being 69.24% ± 0.18 in dichloromethane extract, 64.44% ± 0.04 in ethyl acetate and 53.33% ± 0.09 in acetone extract. The methanol extract of O. basilicum exhibited significant decrease in systolic blood pressure in l-Name induced hypertensive rats at the dose of 50 mg/kg for 28 days. Total phenolic content had a higher linear correlation (r = 0.678) with antihypertensive activity, with a level of significance 95% showing that phenolic compounds in the leaves of the plant has important role in inhibiting l -NAME induced hypertension while flavonoid compounds may play a key role in the antioxidant activities of the plant, through synergism. Conclusively, O. basilicum leaves with bioactive metabolites are a potential source for the development of antihypertensive drugs.

RESUMO

The objective of the present study was to determine the acute and subacute toxicity profile of a polyherbal formulation called "Goubion" in addition to the in vivo antihyperuricemic study using fructose-induced hyperuricemia. Goubion is a combination of Colchicum autumnale (tuber), Tribulus terresteris (fruit), Vitex negundo (leaves), Smilax chinensis (root), Glycyrrhiza glabra (root), and Curcuma amada (rhizome). The acute toxicity study revealed no signs of mortality and morbidity at a single dose of 2000 mg/kg. Similarly, the results of the subacute repeated dose toxicity study exhibited no signs of mortality at any of the doses. However, significant changes in hematological, biochemical, and renal parameters were recorded at the dose of 60 mg/kg. Antihyperuricemic activity was tested at the dose of 15 mg/kg and 20 mg/kg of Goubion, respectively against 5 mg/kg Allopurinol. Based on the antihyperuricemic study, we infer that the Goubion has a significant hypouricemic action, as it remarkably decreased the elevated uric acid levels. The results also suggest the potential inhibitory capability of Goubion on xanthine oxidase dehydrogenase might be the mechanism behind the hypouricemic effect.

RESUMO

Vivabon syrup is a balanced composition of dietary ingredients of phytopharmaceutical nature for maintaining the physique, vigor, vitality and balanced growth of children. The herbal ingredients of pediatric syrup are rich in bioflavonoid, proteins, vitamins, glycosides and trace elements. Vivabon is formulated with herbal drugs such as Phoenix sylvestris, Emblica officinalis, Withania somnifera, Centella asiatica, Amomum subulatum, Zingiber officinalis, Trigonella foenum-graecum, Centaurea behen and Piper longum Catechins are flavan-3-ols that are found widely in the medicinal herbs and are utilized for anti-inflammatory, cardio protective, hepato-protective, neural protection and other biological activities. In general, the dietary intake of flavonoids has been regarded traditionally as beneficial for body growth. Standardization of Vivabon syrup dosage form using HPLC/DAD has been developed for quantitative estimation of Catechin as a chemical marker. The method was validated as per ICH guidelines. Validation studies demonstrated that the developed HPLC method is quite distinct, reproducible as well as quick and fast. The relatively high recovery and low comparable standard deviation confirm the suitability of the developed method for the determination of Catechin in syrup.
