Abstract:
Studies have shown an increasing use of herbal medicines alongside conventional drugs by patients in their disease management especially for chronic diseases, with the attendant risks of herb-drug interactions. In order to forestall this, adequate information about the pharmacological and toxicological profile of herbal medicines and how these would in turn affect the bioavailability of the co-administered drug is required. To evaluate potential herb-drug interactions that could occur in diabetes management in Nigeria- (a) An assessment of available data on the pharmacological and toxicological effects of plants used in diabetes management was conducted as a means of mapping those with identified potential risks for herb-drug interactions; (b) A field work study was carried out in different localities in Nigeria to identify potential pharmacokinetic interactions based on the prescription drugs and herbal medicines co-administered by diabetic patients; and (c) Experimental analysis of plant samples collected during the field work was done to assess their effects on known cell detoxification mechanisms and pharmacokinetic parameters. The results of the research have confirmed the continued use of a wide range of medicinal plants in diabetes management, many of which have not been thoroughly investigated. In addition, 50% of diabetic patients visiting healthcare facilities in Nigeria routinely manage their diabetes or existing co-morbidities with herbal medicines alongside prescription drugs. Even more worrying is the frequent use of unlabeled herbal preparations which would constitute a huge challenge in the proper identification of herb-drug interactions when they occur. Based on previously available data and the experimental results of this research, a number of these herbal medicines have been identified as having overlapping interactions with prescription drugs. There is therefore a need for better regulation of herbal medicine use alongside pharmacovigilance monitoring in Nigeria in order to forestall the occurrence of clinically relevant untoward herb-drug interactions.
