Pharmacokinetics of a fixed combination with propranolol, hydrochlorothiazide and triamterene

The blood levels of propranolol, hydrochlorothiazide and triamterene, three components of a new antihypertensive combination, Dociteren, were studied in patients with mild hypertension after single dosage. The blood levels of propranolol in the combination did not differ from the blood levels obtained after a single dose of propranolol given alone.
