Brief summary

The objective of this study is to evaluate the bioequivalence of the test formulation relative to the that of a reference formulation, following oral administration of a combination single dose of 0.4 mg tamsulosin tablet to healthy male and female subjects under fasting conditions.

Interventions

Single dose, crossover study design whereby each participant receives the test formulation of 0.4 mg tamsulosin tablet on one occasion and the innovator formulation of 0.4 mg tamsulosin tablet on one occasion with each dose separated by a one week washout period. The intervention for this trial is the test tablet formulation. No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for water consumed with the dose). Participants are required not to eat for 10 hours bef

Single dose, crossover study design whereby each participant receives the test formulation of 0.4 mg tamsulosin tablet on one occasion and the innovator formulation of 0.4 mg tamsulosin tablet on one occasion with each dose separated by a one week washout period. The intervention for this trial is the test tablet formulation. No water is allowed for 1 hour prior to dosing until 1 hour after dosing (except for water consumed with the dose). Participants are required not to eat for 10 hours before receiving each dose and to fast for approximately 4 hours after receiving each dose. Bathroom visits will be confined at the Clinical Site for 10 hours prior to dosing to ensure compliance and will be monitored for 24 hours after dosing. 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 ( 1 x. 0.4 mg) 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.
