Comparison of Safety and Efficacy of Tizanidine Hydrochloride Capsules Versus Zanaflex® (Tizanidine Hydrochloride Tablets) Taken While in the Fed State (Just After a Meal) and in the Fasted State (Before a Meal) in Patients With Moderate to Severe Spasticity.

December 10, 2015 updated by: Elan Pharmaceuticals

A Multicenter, Open-Label, Randomized, 4-Way Crossover Trial of the Safety and Efficacy of Tizanidine Hydrochloride Capsules Versus Zanaflex (Tizanidine Hydrochloride) Tablets Taken Under Fed and Fasted Conditions in Patients With Moderate to Severe Spasticity

This study is being conducted to compare the impact of somnolence (sleepiness) on cognition (awareness) as well as the safety and effectiveness of tizanidine hydrochloride capsules versus Zanaflex® (tizanidine hydrochloride tablets) taken while in the fed state (just after a meal) and in the fasted state (before a meal) in patients with moderate to severe spasticity.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
