ETHNOPHARMACOLOGICAL SIGNIFICANCE Pistacia integerrima Stew ex. Brandis is an important component of commonly dispensed traditional dosage forms. We wished to determine whether polyphenolic constituents of this plant could be useful in oxidative stress and have potential to counter hyperuricemia. MATERIAL AND METHODS Radical scavenging activity was(More)
Artemether-lumefantrine is one of the most widely used anti-malarial drug combinations in the world with excellent tolerability and cure rates in adult and paediatric patients with uncomplicated falciparum malaria. The aim of this study was to evaluate the pharmacokinetics of artemether and its active metabolite, dihydroartemisinin, in healthy Pakistani(More)
Polymorphisms in cytochrome P450 (CYP) 2C9 (CYP2C9) gene result in interindividual variability in warfarin dose requirement. There is a need for characterization of genotype frequency distribution in different populations for construction of customized dosing algorithms to enhance the efficacy and reduce the toxicity of warfarin therapy. This study was(More)
Pharmacokinetics of flurbiprofen has been studied in different populations, especially in Caucasian. However, there are very few studies reported from Eastern part of world. Previous studies suggested that genetic and environmental factors may cause inter-individual differences in flurbiprofen disposition, so we investigated the pharmacokinetics of(More)
BACKGROUND This clinical study investigated the pharmacokinetics of standard doses of rifampicin (RMP; 450 and 600 mg) in pulmonary tuberculosis (TB) patients in the context of its high sterilizing potential and the increased frequency of multidrug-resistant TB in Pakistan. The objective of this study was to determine the sufficiency or inadequacy of peak(More)
OBJECTIVE To explore RNA dependent RNA polymerase of Chikungunya virus (CHIKV) and develop T cell based epitopes with high antigenicity and good binding affinity for the human leukocyte antigen (HLA) classes as targets for epitopes based CHIKV vaccine. METHODS In this study we downloaded 371 non-structural protein 4 protein sequences of CHIKV belonging to(More)
BACKGROUND The use of β-blockers is limited by adverse effects such as bronchospasm in asthmatics. Third generation β-blockers such as nebivolol may show better tolerability in asthmatic subjects because they lack β-blocker induced bronchoconstriction. Methods: Effects of nebivolol on the tracheal muscle strips prepared from ovalbumin-sensitised guinea pigs(More)
Pakistan has the second highest burden of hepatitis C (HCV) in the world. The major route of HCV transmission is contaminated blood or needle sharing. Seventy percent of people who inject drugs (PWIDs) shared needles at some time in their addiction history. The aim of the present study was to estimate the prevalence of HCV in PWIDs in cities of Pakistan. We(More)
Polymorphisms in vitamin K epoxide reductase complex subunit 1 (VKORC1) gene lead to interindividual variability in warfarin dose requirement. The characterization of genotype frequency distribution is required in different populations for construction of customized dosing algorithms to enhance the efficacy and reduce the toxicity of warfarin therapy. This(More)
Warfarin is a commonly prescribed anticoagulant existing in two enantiomeric forms S- and R-warfarin. Many techniques have been used to analyze warfarin in plasma but less frequently for enantiomeric analysis. One of the HPLC method employed was further simplified and made economical. Method was validated according to ICH guidelines and was found to be(More)
