Description
|
Amyl Nitrite is an antihypertensive medicine. Amyl nitrite is employed medically to treat heart diseases such as angina and to treat cyanide poisoning. Like other alkyl nitrites, amyl nitrite is bioactive in mammals, being a vasodilator which is the basis of its use as a prescription medicine. As an inhalant, it also has psychoactive effect which has led to illegal drug use. |
| Indication |
For the rapid relief of angina pectoris. |
| Pharmacology |
Amyl nitrite, in common with other alkyl nitrites, is a potent vasodilator. It expands blood vessels, resulting in lowering of the blood pressure. Alkyl nitrite functions as a source of nitric oxide, which signals for relaxation of the involuntary muscles. Physical effects include decrease in blood pressure, headache, flushing of the face, increased heart rate, dizziness, and relaxation of involuntary muscles, especially the blood vessel walls and the anal sphincter. There are no withdrawal symptoms. |
| Toxicity |
Overdose symptoms include nausea, emesis (vomiting), hypotension, hypoventilation, dyspnea (shortness of breath), and syncope (fainting) |
| Affected Organisms |
| • |
Humans and other mammals |
|
| Biotransformation |
Hepatic. The drug is metabolized rapidly, probably by hydrolytic denitration; approximately one-third of the inhaled amyl nitrite is excreted in the urine. |
| Absorption |
Amyl nitrite vapors are absorbed rapidly through the pulmonary alveoli, manifesting therapeutic effects within one minute after inhalation. |
