Filter by:The purpose of this study was to compare the pharmacokinetic profiles at steady state of the test product, 300 mg trazodone hydrochloride (HCl) extended-release caplets (containing Contramid®), when administered once daily, and the reference product, 100 mg trazodone HCl immediate-release tablets (Apotex Corp.), when administered three times daily, for one week. For this purpose, the rate and extent of absorption of trazodone and formation of m-chlorophenylpiperazine (mCPP) after administration of multiple doses of up to 300 mg of each of the two formulations was compared.
Previous studies have indicated that menaquinone-7 (MK-7) is the most effective form of vitamin K. The Japanese soya product natto is one of the richest food sources of MK-7, but its taste is not appreciated by the Western society. For this reason, the active biological compound has been manufactured as enriched oil or casein (≈80% of proteins in cow's milk)-enriched powder. However, cow's milk allergy is the most common cause of food allergy affecting a minimum of 2-3% of infants. The investigators will therefore compare this protein-delivery system to an alternative delivery system (Arabic gum; 98% polysaccharides). To compare the difference between powder and oil as MK-7 delivery vehicle, the investigators will also test the efficacy of enriched linseed oil.
The purpose of this study was to compare the pharmacokinetic profiles at steady-state of the test product, Tramadol HCl Once-A-Day (OAD) 200 mg tablets and the reference product, Tramadol HCl 50 mg (IR) tablets (Ortho-McNeil Ultram®). For this purpose, the extent of absorption of tramadol and formation of O-desmethyltramadol (measures of systemic exposure) after multiple administration of 50 mg 6-hourly at 07:30, 13:30, 19:30 and 01:30 (reference product) and 200 mg 24-hourly at 07:30 (test product), were compared.
The purpose of this study is to evaluate how much and how fast a single, oral, daily 25 mg dose of TMC278 is absorbed into the body when administered as a solution, suspension, granules, or a tablet. In addition, the effect of each formulation of TMC278 will be evaluated in patients in the fasted and fed states and the palatability (how the drug tastes) of each formulation will be assessed. Finally, the safety and tolerability of each formulation of TMC278 will be assessed throughout the study.
This study hypothesis is that anthocyanins from cranberry juice are bioavailable and can be measured in blood and urine after a single acute consumption of cranberry juice.
Compare the rate and extent of absorption of famotidine 40 mg tablets, administered as 1 x 40 mg tablet under fed conditions.
Compare the rate and extent of absorption of famotidine 40 mg tablets, administered as 1 x 40 mg tablet under fasting conditions.
The purpose of this study is to determine whether two oral formulations of Gemfibrozil Tablets are bioequivalent.
This is a randomized, open-label, multi-center, 4-treatment, 4-period crossover study. Approximately 72 healthy, surgically sterile or postmenopausal subjects will be enrolled and have urine collected over 72 hours following administration of risedronate for all 4 treatment periods).
1. To estimate the absorption of a single oral dose of a controlled release varenicline tablet under fed and fasted conditions. 2. To evaluate the pharmacokinetics, safety, and tolerability of a single dose of a varenicline controlled release tablet under fed and fasted conditions.
