The pharmacokinetics of oral ranitidine were studied in 24 Mexican male healthy volunteers. Subjects received a tablet containing 150 mg of ranitidine (Azantac TM, Glaxo de Mexico, Mexico, City) after an overnight fast and blood samples were drawn at several times for a period of 24 h. Ranitidine concentration in plasma was measured by high performance liquid chromatography and pharmacokinetic parameters were determined by non-compartmental analysis. Ranitide plasma concentration increased with time, reaching a maximum of (mean ñ SEM) 484 ñ 34 ng/ml in 2.7 ñ 0.2 h. Plasma levels then decayed with a terminal half-life of 4.8 ñ 0.3 h. The area under the plasma concentration against time curve was 2440 ñ 126 ngh/ml. Oral ranitidine pharmacokinetic parameters in mexicans appeared to be similar to those previously reported for caucasians
