Artegodan

Artegodan - General Information

An alkaloid found in opium but not closely related to the other opium alkaloids in its structure or pharmacological actions. It is a direct-acting smooth muscle relaxant used in the treatment of impotence and as a vasodilator, especially for cerebral vasodilation. The mechanism of its pharmacological actions is not clear, but it apparently can inhibit phosphodiesterases and it may have direct actions on calcium channels.

 

Pharmacology of Artegodan

Artegodan is a nonxanthine phosphodiesterase inhibitor for the relief of cerebral and peripheral ischemia associated with arterial spasm and myocardial ischemia complicated by arrhythmias. The main actions of Artegodan are exerted on cardiac and smooth muscle. Like qathidine, Artegodan acts directly on the heart muscle to depress conduction and prolong the refractory period. Artegodan relaxes various smooth muscles. This relaxation may be prominent if spasm exists. The muscle cell is not paralyzed by Artegodan and still responds to drugs and other stimuli causing contraction. The antispasmodic effect is a direct one, and unrelated to muscle innervation. Artegodan is practically devoid of effects on the central nervous system. Artegodan relaxes the smooth musculature of the larger blood vessels, especially coronary, systemic peripheral, and pulmonary arteries.

Artegodan Contraindications

Intravenous injection of papaverine is contraindicated in the presence of complete atrioventricular heart block. When conduction is depressed, the drug may produce transient ectopic rhythms of ventricular origin, either premature beats or paroxysmal tachycardia.

Papaverine hydrochloride is not indicated for the treatment of impotence by intracorporeal injection. The intracorporeal injection of papaverine hydrochloride has been reported to have resulted in persistent priapism requiring medical and surgical intervention.

 

Additional information about Artegodan

Artegodan Indication: For the treatment of impotence
Mechanism Of Action: Perhaps by its direct vasodilating action on cerebral blood vessels, Artegodan increases cerebral blood flow and decreases cerebral vascular resistance in normal subjects; oxygen consumption is unaltered. These effects may explain the benefit reported from the drug in cerebral vascular encephalopathy.
