Inhalation Devices. These devices use heat to vaporize a drug so that it can be inhaled into the lungs. Clinical trials are currently testing this device with procholorperazine (Compazine), a tranquilizer drug that is used to treat nausea and vomiting.
Nasal Devices. New types of nasal sprays and powders are being researched. Some of them use capsaicin, the chemical found in cayenne peppers, to help relieve pain.
Skin Patches. The Actyve transdermal patch uses a small battery-powered system to deliver a triptan drug through the skin.
Drugs. New drugs in development include tonabersat (gap junction blocker), trexima (combination triptan and non-steroidal anti-inflammatory drug), and GW274150 (nitric oxide synthase inhibitor).
