Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study design is an Open-Label Randomized, Single-Dose, 2-way Crossover Bioequivalence Study with a washout period of 14 days. During each session, the subjects will be administered a single dose of 20 mg Paroxetine (one Paroxetine Hydrochloride Tablet 20mg or one Paxil® Tablet 20 mg) under Fasting and Fed conditions. Venous blood samples will be collected at pre-dose (0 h), and up to 96 h post dose.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.
