商品名：Nitrol, Nitro-bid, and Nitrostat
Nitrate. Nitrovasodilator. Like other nitrovasodilators, it relaxes vascular smooth muscle (especially venous) via generation of nitric oxide. Nitric oxide stimulates guanylate cyclase to produce cyclic guanosine monophosphate (GMP) in vascular smooth muscle and relax smooth muscle. Nitric oxide–generating compounds may also help decrease gastric adverse effects associated with nonsteroidal anti- inflammatory drugs (NSAIDs).
Nitroglycerin, like other nitrovasodilators, is used primarily in heart failure or pulmonary edema to reduce preload or decrease pulmonary hypertension. Use in animals has been primarily derived from empirical use and experience in humans. There are no well-controlled clinical studies or efficacy trials to document clinical effectiveness. In people, they are used to treat angina pectoris. In horses, nitroglycerin has been used to improve blood flow to the feet in the management of laminitis. However, in experiments, this treatment was not effective in horses and did not increase blood flow to the feet.
