Effects of lasofoxifene on the pharmacokinetics and pharmacodynamics of single-dose warfarin.

Aim: To investigate the effect of steady-state lasofoxifene on the pharmacokinetics and pharmacodynamics of warfarin.

Methods: Twelve healthy postmenopausal women received warfarin (single 20-mg dose) alone and during lasofoxifene. R- and S-warfarin concentrations, prothrombin time (PT) and international normalized ratio (INR) were determined with each treatment.

A single-dose pharmacokinetic study of lasofoxifene in healthy volunteers and subjects with mild and moderate hepatic impairment.

Lasofoxifene, a selective estrogen receptor modulator for osteoporosis management, is metabolized primarily by hepatic oxidation and conjugation. This study compared the pharmacokinetics of 0.25 mg lasofoxifene in subjects with mild (Child-Pugh grade A, n = 6) or moderate (Child-Pugh grade B, n = 6) hepatic impairment and healthy volunteers (n = 6).

Effect of lasofoxifene on the pharmacokinetics of digoxin in healthy postmenopausal women.

Lasofoxifene is in late-stage development for the prevention and treatment of osteoporosis. Digoxin is commonly prescribed for arrhythmias and congestive heart failure, has a narrow therapeutic index, and may be coadministered with lasofoxifene. This study was conducted to determine the effect of lasofoxifene (4-mg loading dose on day 11 followed by 0.

Pharmacokinetics of quinapril in children: assessment during substitution for chronic angiotensin-converting enzyme inhibitor treatment.

Quinapril pharmacokinetics were studied in infants and children using a novel study design that allowed substitution of quinapril for one dose of the current chronic angiotensin-converting enzyme (ACE) inhibitor treatment. A total of 24 patients ranging in age from 2.5 to 82 months who were receiving an ACE inhibitor held their usual treatment on the study day and received a 0.
