The pressor effect of ARAMINE (metaraminol) begins in 1 to 2 minutes after intravenous infusion, in about 10 minutes after intramuscular injection, and in 5 to 20 minutes after subcutaneous injection. The effect lasts from about 20 minutes to one hour. ARAMINE (metaraminol) has a positive inotropic effect on the heart and a peripheral vasoconstrictor action.
Renal, coronary, and cerebral blood flow are a function of perfusion pressure and regional resistance. In patients with insufficient or failing vasoconstriction, there is additional advantage to the peripheral action of ARAMINE (metaraminol) , but in most patients with shock, vasoconstriction is adequate and any further increase is unnecessary. Blood flow to vital organs may decrease with ARAMINE (metaraminol) if regional resistance increases excessively.
The pressor effect of ARAMINE (metaraminol) is decreased but not reversed by alpha-adrenergic blocking agents. Primary or secondary fall in blood pressure and tachyphylactic response to repeated use are uncommon.
