Pharmacokinetic properties of isosorbide-5-mononitrate under fasting and fed conditions in healthy male subjects.

Objective: This study was performed to compare the pharmacokinetic properties and relative bioavailability of two isosorbide-5-mononitrate (5-ISMN) sustained-release drugs in healthy Korean subjects under fasting and fed conditions.

Methods: A total of 60 healthy volunteers (30 each in the fasting and fed arms of the study) were enrolled in the study and were randomized to treatment. After the administration of a single dose of one of the investigational products, blood samples were collected at specific time intervals from 0 to 36 hours.

Pharmacokinetic comparison study of a combination containing 500 mg of Naproxen and 20 mg of Esomeprazole: a randomized, single-dose, 2-way crossover, open-label study in healthy Korean men.

Purpose: Nonsteroidal anti-inflammatory drugs have been used for analgesic, anti-inflammatory, and antithrombotic effects, but they carry a risk of major gastrointestinal damage. This risk can be greatly reduced by the coadministration of inhibitors of gastric acid secretion, such as proton pump inhibitors. This study was performed for the subsequent marketing of a combination drug that contained 500 mg of naproxen and 20 mg of esomeprazole in Korea.

Pharmacokinetic properties and bioequivalence of olmesartan medoxomil/hydrochlorothiazide in healthy Korean male subjects.

Unlabelled: Olmesartan medoxomil inhibits the vasoconstrictor effects of angiotensin II. Hydrochlorothiazide (HCTZ) promotes sodium excretion, resulting in a reduction of plasma volume and peripheral resistance. A combination of these agents is known to have a greater effect for the treatment of hypertension than monotherapy with either one of these components.
