Comparative bioequivalence study of the Tizanidine Hydrochloride 4 mg tablet manufactured by Amin Pharmaceutical Company

Protocol summary

Study aim
Examining the bioequivalency of domestically produced Tizanidine Hydrochloride tablet with brand samples(Sirdalud®)
Design
A single-group, not blinded, not randomized, bioequivalence clinical trial on 24 healthy volunteers.
Settings and conduct
Study place: Drug Applied Research Center affiliated to Tabriz University of Medical Science. The number of 24 volunteer in the age range of 18-50 years and the Body Mass Index range of 18-30, who are voluntarily selected through public notification. a Tizanidine Hydrochloride 4 mg tablet is taken fasting and blood is taken at 13 times point. One week later, the process is repeated for the brand medicine.
Participants/Inclusion and exclusion criteria
The weight range of participating candidates should be between 60-100 kg. All candidates must be non-smokers. Candidates should be healthy in terms of physical examination, ECG and the following laboratory tests: Hemoglobin, Hematocrit, Red and White Blood Count, MCV (Mean Body Volume), MCH (Mean Body Hemoglobin), Routine Urinalysis, Total Cholesterol, Triglyceride, Total Proteins, albumin, uric acid, total bilirubin, alkaline phosphatase, Gamma Glutamyl transpeptidase (γ-GT), aspartate aminotransferase (AST), alanine aminotransferase (ALT), urea, creatinine and fasting blood glucose. Volunteers who have agreed to an informed consent form.
Intervention groups
After taking a Tizanidine Hydrochloride 4 mg tablet from domestic company, 3 milliliters of blood will be collected from the volunteer in 13 times intervals for 12 hours. One week later, the process is repeated for a brand sample tablet. The drug concentration is measured in plasma.
Main outcome variables
Studying the Drug pharmacokinetic parameters including measuring the plasma concentrations for brand and test products, determining the desired and important pharmacokinetic parameters in bioequivalence studies, AUCs, Tmax, Cmax, T1/2.

Description
Intervention group: This study examines the bioequivalence of the tizanidine tablet produced by a domestic company with a foreign brand sample. We have only one intervention group and there is no control group. The intervention group, which includes healthy, fasting volunteers, will receive a single dose, 4 mg tablet manufactured by the pharmaceutical company Amin and Sirdalud brand, in two 12-hour periods with an interval of one week, on the day of the study. And in 13 different time periods up to 12 hours after taking the medicine, blood samples will be taken from the volunteers in the amount of 3 ml each time, that is, a total of 39 ml within 12 hours. The training that will be given to the volunteers includes avoiding the consumption of drinks containing alcohol and xanthine and other interfering drugs in the prescription drug from 48 hours before the start of the study until the end of the study.
