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.
