Absorption
Absolute bioavailability following a single 300 mg oral dose of eprosartan is approximately 13%. Eprosartan plasma concentrations peak at 1-2 hours after an oral dose in the fasted state.
Plasma concentrations of eprosartan increase in a slightly less than dose-proportional manner over the 100-800 mg dose-range. The terminal elimination half-life of eprosartan following oral
administration is 5-9 hours. Eprosartan does not significantly accumulate with chronic use.
The bioavailability of eprosartan and hydrochlorothiazide is not influenced by food, but
absorption is delayed. Peak plasma concentrations occur at 4 hours after dosing for eprosartan
and 3 hours for hydrochlorothiazide.
