  A randomized, open-label, balanced, three-treatment, three-sequence, three-period single dose crossover pharma- cokinetic interaction study was conducted to evaluate the potential of interaction between Atorvastatin (AT) and Losartan (LS). Subjects were administered either 40 mg AT or 100 mg LS or combination of both in either of the periods. Blood samples were collected at regular intervals to measure the plasma concentrations of AT, O-hydroxy atorvastatin (O-HAT), LS and its carboxylic acid metabolite (LS-CA) for pharmacokinetic analysis. Co-administration of AT and LS was well tolerated without any significant change in area under the curve (AUC) of either of the drugs or their respective metabolites. There was an increase in C max (ng/mL) of AT, O-HAT, LS, and LS-CA by 29% (38.8(±20.9) to 47.8(±18.4)), 86% (15.7±(10.6) to 29.8(±19.1)), 51% (503.0(±246.0) t.. View More»
