Protocol summary
-
Study aim
-
Bioequivalence Study of ٰValsartan tablet 160mg manufactured by Sanamed company versus originator brand (Diovan 160mg) manufactured by Roche company
-
Design
-
Bioequivalence study, crossover, a blind, 24 healthy volunteers. Simple randomization was used for randomization
-
Settings and conduct
-
The study will be conducted in a single-blinded, cross-over and fasting, and on two series of healthy volunteers. The study will be conducted in two periods (48h). The interval between these two periods, which is called the wash-out time, is determined by the half-life of the drug plasma, which according to scientific sources at this time should be at least 5 to 7 half-life of the drug. Given that the biological half-life of the drug is in drug form, the time to clear the drug will be one week. Blood samples are taken by the doctor immediately before and after the drug is taken by the volunteers, and the steps for preparing the samples include plasma separation and drug extraction to analyze the amount of drug on them.

Participants/Inclusion and exclusion criteria
-
Inclusion Criteria: General Health (Liver, Heart, and Kidney), Body Mass Index (18-28), Informed consent, Age (18-45 years old) Exclusion criteria: Smoking, History of cardiovascular disease, History of liver and kidney disease, Pregnancy, Alcoholism and Narcoticism, History of allergy to ٰValsartan
-
Intervention groups
-
In this study, two groups of intervention and control are not applicable. Both groups will receive test-reference medicine and testing on two different occasions, and therefore the test results will be independent of individual differences and will only indicate differences in the formulation of the two drugs.
-
Main outcome variables
-
Maximum drug concentration, Time to reach to maximum drug concentration, Half life of drug

Randomization description
-
People in the mentioned age group are invited to participate through the advertisement. People are then checked for health and healthy volunteers are identified. Each candidate is assigned a number from 1 to 24. The numbers are written on a plastic ball and poured into a container and mixed. The balls are then removed randomly from the container. The first twelve are considered as (first sequence: Valsartan 160mg manufactured by Sanamed recipient) and the second twelve are considered as (second sequence: Diovan 160mg recipient). The volunteers don't have any information about taking the test drug or brand drug
