Medical, Legal & Regulatory (MLR) Review Guide

Understand how pharmaceutical organizations audit, annotate, and approve promotional healthcare communications prior to commercial release.

Published: September 28, 2026•Last updated: October 7, 2026

MLR stands for Medical, Legal, and Regulatory review—the cross-functional audit process required within pharmaceutical companies and medical communication agencies before promotional materials can be distributed to healthcare professionals (HCPs) or patients.

Because healthcare promotional materials directly influence treatment decisions, health authorities (such as the US FDA OPDP, Health Canada, and European regulators) enforce strict standards regarding truthfulness, scientific substantiation, and risk disclosure. The MLR review serves as an internal safeguard to prevent misleading claims, protect patient safety, and maintain legal compliance.

Note on Industry Terminology: While widely known as MLR, individual organizations may refer to this process as PRC (Promotional Review Committee), LMR (Legal, Medical, Regulatory), or Copy Clearance. Workflows described on this page represent general industry educational principles rather than a single universal software implementation.
