Summary

The purpose of the study is to determine whether Diltiazem Hydrochloride 2% Cream will cause irritation to skin on the back of healthy volunteers after repeated application over 21-days.

Clinical Details

Official title: A 21-Day, Randomized, Controlled Study to Evaluate the Irritation Potential of Diltiazem Hydrochloride 2% Cream in Healthy Subjects, Using a Cumulative Irritant Patch Test Design

Study design: Allocation: Randomized, Endpoint Classification: Safety Study, Intervention Model: Single Group Assignment, Masking: Double Blind (Subject, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Mean cumulative irritation score of Diltiazem Hydrochloride 2% Cream in healthy skin of humans.

Detailed description: The primary objective of this study will be to determine the potential of Diltiazem Hydrochloride 2% Cream to cause irritation after repeated topical application to the healthy skin of humans under controlled conditions. In addition, safety will be assessed by evaluation of any adverse events (AEs) reported during the study.
