Primary Outcome Measures

Name	Time	Method
The bioequivalence of vildagliptin/metformin 50 mg/1000 mg film-coated tablets (test product, Alpha Pharma, Kingdom of Saudi Arabia) and Galvusmet® 50 mg/1000 mg film-coated tablets (reference product, Novartis Pharma, Switzerland), in healthy adult subjects under fed conditions. A validated (liquid chromatography with tandem mass spectrometry [LC-MS/MS]) method of analysis is used to analyze vildagliptin and metformin in human plasma samples with a lower limit of quantification (LLOQ) of 0.50 ng/ml for vildagliptin and 20.00 ng/ml for metformin. A total of 19 blood samples were collected for this study in tubes containing lithium-heparin according to the following schedule: pre-dose (BK) 1 sample, 0.25, 0.50, 0.75, 1.00, 1.50, 2.00, 2.25, 2.50, 2.75, 3.00, 3.50, 4.00, 5.00, 6.00, 8.00, 10.00, 12.00, 24.00 hours post-dosing in each study period.<br>

Secondary Outcome Measures

Name	Time	Method
The safety and tolerability of a single dose administered in healthy human adult subjects under fed conditions, measured using:<br>1. Full vital signs (blood pressure, pulse rate, and body temperature) measured, in a sitting position, at pre-dosing and at the following times: 0.50, 1.00, 1.50, 2.00, 3.00, 4.00, 6.00, 8.00, 12.00, and 24.00 hours post-dosing in each study period<br>2. Glucose blood test performed at 1 h before dosing, every 30 minutes during the first 4 hours post-dosing, and 5 h, 6 h, 7 h, 8 h, 12 h, and 24 h post-dosing<br>3. A final examination at the end of period II including vital signs, physical examination, ECG, and clinical laboratory examinations (full blood count, clinical chemistry, and urinalysis)
