Single Dose Pharmacokinetics of Metoclopramide Oral Tablets Utilizing HPLC-UV Method

Background: Metoclopramide is a potent dopaminergic antagonist utilized for treating gastrointestinal disorders. The aim of this study was to examine the pharmacokinetics of oral formulation of metoclopramide in the Pakistani volunteers. Methods: This open label, single dose, pharmacokinetic study was executed in non-smoking, 12 Pakistani healthy males, treated with a single 20 mg oral tablet dose of metoclopramide on test day. Maximum plasma concentration (Cmax), time to achieve Cmax (Tmax), and area under curve (AUC0-t) of metoclopramide were determined analyzing the serial blood samples using a validated HPLC-UV method. Results: The determined values of Cmax, Tmax, and AUC0-t of metoclopramide were 34.51 ± 4.91 ng/ml, 1.56 ± 0.18 and 273.88 ± 114.49 ng.h/ml, respectively. Conclusion: The results reveal that the findings of Pakistani individuals are slightly different when compared with the published data of other ethnic origins.
