Last Updated: 2024-02-20

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1
• Total Enrollment: 61 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-08-23
• Study Completion Date: 2021-09-08

Brief Summary

The objective of the study is to compare the bioequivalence of a New Paracetamol Oral Suspension 24 milligram/milliliter (mg/ml) with that of an already approved Paracetamol (24 mg/ml) Oral Suspension (Panadol Baby & Infant) when administered to healthy volunteers under fasting condition. Pharmacokinetic parameters will be calculated from plasma concentration data. The rate and extent of absorption of the formulations will be compared.

Detailed Description

This will be a 2-arm, single center, single dose, open-label, randomized, two-sequence, two period crossover, bioequivalence study in healthy adult participants. Participants will be screened for eligibility within 15 days prior to dosing. Participants will receive each of the two study treatments in fasted state during a 6-day (5-overnight stay) residential period at the study site. Participants will receive both treatment regimens in a randomized order with a 72-hour washout period between each dose. During each treatment period, a total of 21 blood samples will be collected which will include a pre-dose blood sample 1 hour before dosing and 20 post-dose blood samples at 5, 10, 20, 30, 40, 50, 60, 80, 90, 120, 150, 180 minutes, 4, 5, 6, 8, 10, 12, 14, 16 hours, for bioanalytical analyses of paracetamol.
