Water will not be allowed for 1.00-hour pre dose and 1.00-hour post dose on Day 28. Pre-dose blood sample (~4 mL) will be collected within 5 minutes before dosing on Day 26, 27 and 28 to confirm steady state. Day 28 :On the day of complete pharmacokinetic sampling the post dose venous blood samples (~4 mL) will be withdrawn at 1.00, 2.00, 3.00, 4.00, 5.00, 6.00, 7.00, 8.00, 9.00, 10.00, 11.00, 12.00, 14.00, 16.00, 20.00 and 24.00 hours post dose administration. End of Study assessments will be performed after the last sample is collected on day 29 in Period II and then patient will be discharged from the clinical facility.
