Comparative assessment of the absorption of a generic formulation of a combination N-(4-hydroxyphenyl)acetamide/(RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension against two innovator formulations administered simultaneously of N-(4-hydroxyphenyl)acetamide oral suspension and (RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension conducted under fasting conditions in healthy volunteers.

The combination test formulation of 1 x 10 ml of 250/100 mg N-(4-hydroxyphenyl)acetamide/(RS)-2-(4-(2-Methylpropyl)phenyl)propanoic acid oral suspension on one occasion. The intervention for this trial is the test oral suspension formulation. No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with each dose). Participants are required not to eat for 10 hours before dosing and to fast for approximately 4 hours after each dose. Bathroom visits will be supervised to ensure no unauthorized water or food intake and for personal safety. Participants will be confined at the Clinical Site for 12 hours prior to dosing to ensure compliance and for 14 hours after dosing. Participants will be monitored for adverse events throughout the study. Standard meals will be consumed at the Clinical Site with no additional food intake allowed. The standard meals will be consumed 4 hours and 9 hours after dosing (at approximately 12pm and 5pm). Alcohol breath testing and dipstick drugs of abuse tests will be performed upon each participant reporting to the clinical site 12 hours prior to dosing. Screening and study exit laboratory tests will be completed to assess the health of the participants along with HIV, Hepatitis and drugs of abuse testing. Each dose will be taken orally with 240 ml of water at ambient temperature. Medication must swallow the entire suspension and a mouth check will be conducted to ensure that the medication has been taken as directed.
