This report describes the latest concepts of the role of nitric oxide (NO) in health and disease as a basis for therapeutics and development of new drugs. Major segments of the market for nitric oxide-based drugs are described as well as the companies involved in developing them.

Nitric oxide (NO) can generate free radicals as well as scavenge them. It also functions as a signaling molecule and has an important role in the pathogenesis of several diseases. A major focus is delivery of NO by various technologies. Another approach is modulation of nitric oxide synthase (NOS), which converts L-arginine to NO. NOS can be stimulated as well as inhibited by pharmacological and gene therapy approaches.

Important therapeutic areas for NO-based therapies are inflammatory disorders, cardiovascular diseases, erectile dysfunction, inflammation, pain and neuroprotection. The first therapeutic use of NO was by inhaltion for acute respiratory distress syndrome (ARDS). NO-donors, NO-mimics and NOS modulators are described and compared along with developmental status. NO-related mechanisms of action in existing drugs are identified.

Various pharmacological approaches are described READ MORE >
