Conditions
Brief summary
The objective of this study is to evaluate the bioequivalence of the test (new) formulation of 1 x 20 mg against the reference formulation (innovator brand of 1 x 20 mg tadalafil tablet) following oral administration of a single dose of 20 mg in healthy male subjects under fed conditions.
Interventions
Single dose, crossover study design whereby each participant receives the test formulation of tadalafil (1 x 20 mg) on one occasion and the innovator formulation of tadalafil (1 x 20 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of tadalafil.
No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose).
Participants are required not to eat for 10 hours
Single dose, crossover study design whereby each participant receives the test formulation of tadalafil (1 x 20 mg) on one occasion and the innovator formulation of tadalafil (1 x 20 mg) on one occasion with each dose seperated by a one week washout period. The intervention for this trial is the test formulation of tadalafil. No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for the water consumed with the dose). Participants are required not to eat for 10 hours prior to receiving breakfast. Subjects will be provided with a standardised high fat breakfast which they must start eating 30 minutes prior to dosing. Subjects are required to fast for approximately 4 hours after receiving each dose. Bathroom visits will be supervised to ensure no unauthorised water or food intake and for personal safety. Participants will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored for 24 hours. Standard meals will be consumed at the Clinical Site with no additional food intake allowed. Alcohol breath testing will be performed upon each participant reporting to the Clinical Site 10 hours prior to dosing. Pre and post study laboratory tests will be completed to assess the health of 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 be swallowed whole and a mouth check will be conducted to ensure the medication has been taken as directed.
