Aspiral

Aspiral - General Information

Aspiral 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.

 

Pharmacology of Aspiral

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.

 

Aspiral for patients

Amyl nitrite should be taken by the patient when seated or lying down.

 

Aspiral Interactions

Taking amyl nitrite after drinking alcohol may worsen side effects and may cause severe hypotension and cardiovascular collapse.

 

Aspiral Contraindications

Since it may increase intraocular and intracranial pressures, amyl nitrite is contraindicated or should be used with great caution in patients with glaucoma, recent head trauma or cerebral hemorrhage.

Amyl nitrite can cause harm to the fetus when it is administered to a pregnant woman because it significantly reduces systemic blood pressure and blood wflow on the maternal side of the placenta.

 

Additional information about Aspiral

Aspiral Indication: For the rapid relief of angina pectoris.
Mechanism Of Action: Amyl nitrite's antianginal action is thought to be the result of a reduction in systemic and pulmonary arterial pressure (afterload) and decreased cardiac output because of peripheral vasodilation, rather than coronary artery dilation. As an antidote (to cyanide poisoning), amyl nitrite promotes formation of methemoglobin, which combines with cyanide to form nontoxic cyanmethemoglobin.
