简要总结
| As per the randomized study code, patients will be instructed to take either test product or reference product (suspension) 600 mg/5 mL (three times daily at 8.00 hours interval i.e. morning, afternoon and evening dose) orally, for the first seven days (days: 1-7 for Period-I and 11-17 for Period-II) in each study period. |
During hospitalization, patients will be fasted for at least 10.00 hours prior to morning dose on day 8, day 9, day 10 in Period-I and day 18, day 19, day 20 in Period-II, respectively.
Patients will be administered stabilized treatment of Felbamate Oral suspension 600 mg/5 mL thrice a day (either test product or reference product) as per their randomization study code and stable down titrated dose of antiepileptic drug with 240 ±2 mL of water.
Drinking water will not be allowed 1.00 hour before and after morning drug administration on day 8, day 9, day 10 (Period-I) and on day 18, day 19, day 20 (Period-II) except for 240 ±2 mL of water administered during dosing. At all other times drinking water will be provided ad-libitum.
Patient will remain in sitting posture for 2 hrs post morning doses on day 8, day 9, day 10 during Period-I and day 18, day 19, day 20 during Period-II.
Drug administration will be ensured by the dosing personnel that the suspension is completely swallowed by the patient with a thorough check of the oral cavity using a flash light immediately after drug administration. Patients will be instructed to consume it whole with specified quantity of water. The dose will be administered in a staggered manner to maintain subsequent blood collection schedule. Record of drug administration for individual patient will be maintained in source document and Case Report Form.
Administration Procedure:
Subject will receive 600mg/ 5 mL of oral suspension with 60 mL of water (to assure complete consumption of dosage) on the day of dosing as per the randomization schedule and remaining volume 180mL (240-60=180mL) of water will be used for rinsing the syringe. After rinsing, subject will be instructed to drink remaining 180 mL of water with swirling.
Administration Procedure during Out-patient:
Subjects are instructed to consume 600mg/5ml of suspension with the help of graded cap provided with reference or test product. After consuming the specified quantity subjects are advised to rinse the graded cap with water and allowed to swallow to ensure total consumption of medication.
