Pharmacokinetics, pharmacodynamics and bioavailability of the ACE inhibitor ramipril.

The pharmacokinetics and pharmacodynamics of the prodrug ramipril and its active ACE-inhibiting metabolite ramiprilat were investigated in an open, randomised, three-way cross-over study in 12 healthy male volunteers. Subjects received 2.5 mg ramipril orally, 2.5 mg ramipril intravenously and 2.5 mg ramiprilat intravenously.
