Collegium Pharmaceutical's wisdom is in developing over-the-counter and prescription drugs for a variety of conditions affecting the skin and central nervous and respiratory systems. Typically the company starts with existing drugs and works to improve them through new delivery systems that modify their release, or prevent abuse. It is working with drugs to treat such conditions as fibromyalgia, pain, and sleep apnea. Through its subsidiary Onset Therapeutics, the company markets wound care and dermatology (acne, skin infections) drugs. Its topical aerosol product Exactacain is licensed and sold by Healthpoint while its approved allergy nasal spray AllerNaze is licensed to Lupin Ltd.
