Doxycycline Monohydrate 25 mg (5mL) Oral Suspension Under Fed Conditions

August 15, 2024 updated by: Teva Pharmaceuticals USA

A Single-Dose, 2-Period, 2-Treatment, 2-Way Crossover Study of Doxycycline Monohydrate 25 mg as a 5mL Oral Suspension Under Fed Conditions

The objective of this study was to compare the rate of absorption and the oral bioavailability of a test formulation of doxycycline monohydrate 1 x 25 mg (5mL) oral suspension manufactured by IVAX Pharmaceuticals, Inc. and distributed by TEVA Pharmaceuticals USA to an equivalent oral dose of the commercially available reference product, Vibramycin Monohydrate® manufactured by Pfizer, Inc. Following an overnight fast of at least 10 hours, subjects consumed a standard high-calorie. high-fat breakfast meal. This standard breakfast meal began 30 minutes prior to each 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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers
