Lack of Interaction between Modified-Release Fluvastatin and Amlodipine in Healthy Subjects.

Objective: To investigate the potential for a pharmacokinetic interaction between fluvastatin modified-release 80mg tablet (Lescol((R)) XL; fluvastatin XL) and amlodipine 5mg tablet (Norvasc((R))) following multiple once-a-day doses for 2 weeks.

Design: This was a single-centre, six-sequence, three-period, randomised, crossover design study. Fluvastatin XL 80mg tablet and amlodipine 5mg tablet were administered once a day for 2 weeks either alone or in combination.

Pharmacokinetics of multiple doses of valsartan in patients with heart failure.

Angiotensin II has adverse actions in heart failure including vasoconstriction, aldosterone secretion, and activation of the sympathetic nervous system. Valsartan, a potent specific angiotensin II type 1 receptor blocker, may produce beneficial effects in heart failure. The purpose of this study was to evaluate the steady-state pharmacokinetics of valsartan 40, 80, and 160 mg each given every 12 h for 7 days in heart failure patients.
