Zamri obtained his BSc in Chemistry and MSc in pharmacology from the University of Malaya and later PhD in Clinical Pharmacology from the University of London (UK). He later joined the Department of pharmacology, University of Malaya as a senior lecturer and was promoted to Associate Professor in 2015. Currently he serves as head of Pharmacology Department and also Head of University of Malaya Bioequivalence Testing Centre (UBAT). His scope of research includes bioavailability and pharmacokinetic studies in human trials and also for in vivo pharmacokinetic studies using animal models. In animal models his research area further divided into conventional pharmacokinetic studies and also microdialysis which involve the measurement of drug in plasma as well as in the tissue such as brain, subcutaneous tissue, etc. His other research includes the development of transdermal and topical drug delivery system using semi solid base such as palm oil derivatives, studies on PLGA nanoparticles for the delivery of anticancer agents and bioavailability studies on other agents for anticancer. Apart from human clinical trials and preclinical studies in animals, his research also covers the screening and testing of natural product compounds derive from selected local plants. His laboratory also provides services and research in food contaminations, adulterated pharmaceutical products, xenobiotic studies on certain chemicals such as endocrine disruptors in food products, human bodies, etc. by the use of the equipments such as GCMS, HPLC, LCMSMS, etc. Apart from his research activities, he also actively provided consultation to local pharmaceutical companies to conduct testing on pharmaceutical formulations especially for bioequivalence studies, comparative dissolution, etc. His bioequivalence laboratory has conducted more than 40 bioequivalence studies for generic drug formulations and also conducting drug analysis in biological and pharmaceutical products by using state of the art chromatographic techniques such as gas chromatographic (GCMS) and liquid chromatographic mass spectrometric (LCMSMS), etc. His UBAT laboratory has two accreditations which are MS ISO 17025 for chemical testing and Ministry of Health compliance program to conduct bioequivalence studies.
