Abstract

The antihistamines: Piriton, cypron, and Tavagyl are among the most common group of H1- antagonist used to manage cellular responses caused by histamine release in Nigeria and like any other drug, they have some side effects at therapeutic doses and toxic doses. The effects of the antihistamine piriton, Cypron, and Tavagyl on the activities of plasma Acid phosphatase (EC.3.1.3.2), and lactate dehydrogenase (EC.1.1.1.27) of rat were determined at an optimum Temperature of 370c pH 6.0, and 370c pH 8.0. Piriton, Cypron, and Tavagyl were found to increase Acid phosphatase activity. For instance, at maximum piriton, cypron, and Tavagyl dose of 0.04mg/ 300g body weight, and 30 days duration, ACP activity increased by 65.33±0.88% (P>0.05), 69.67±0.33% (P
