isoproterenol

 [i″so-pro-ter´ĕ-nol]
a synthetic adrenergic, used in the form of the hydrochloride and sulfate salts as a bronchodilator, and in the form of the hydrochloride salt as a cardiac stimulant.

i·so·pro·te·re·nol

(ī'sō-prō-ter'ĕ-nol),
A sympathomimetic β-receptor stimulant possessing the cardiac excitatory, but not the vasoconstrictor, actions of epinephrine. Chemically it differs from epinephrine in having an isopropyl group replacing the methyl group attached to the nitrogen atom; rarely used because of the availability of more specific agents.

isoproterenol

/iso·pro·te·re·nol/ (-pro-ter´ĕ-nol) a sympathomimetic used in the form of the hydrochloride and sulfate salts as a bronchodilator, and in the form of the hydrochloride salt as a cardiac stimulant.

i·so·pro·te·re·nol

(ī'sō-prō-ter'ĕ-nol)
Sympathomimetic β-receptor stimulant possessing cardiac excitatory, but not the vasoconstrictor, actions of epinephrine.

Es bien conocido que los adreno-receptores [beta]1 y [beta]2 coexisten en el tejido coronario humano y su estimulacion produce efectos inotropicos positivos en preparaciones auriculares (16) y ventriculares humanas (36,37), asi como en diversos animales de experimentacion incluyendo ratas y ratones (38), hecho confirmado en la presente investigacion, usando isoproterenol como agonista.

Hypotension can be treated with fluids and vasoconstrictors such as norepinephrine or phenylephrine, but because quetiapine is a potent a1 receptor antagonist, vasopressors with p2 activity such as epinephrine or isoproterenol may worsen the hypotension (13).

Care should be exercised when administering adrenergic agents, such as isoproterenol, to patients with an Amantadine overdose, since the dopaminergic activity of Amantadine has been reported to induce malignant arrhythmias.
Las pruebas con isoproterenol y atropina, bajo estricto monitoreo electrocardiografico, pueden tambien ser utiles a la hora de realizar el diagnostico; los estudios electrofisiologicos, por su parte, tienen baja sensibilidad y especificidad, y, por tanto, no se los recomienda de manera rutinaria dentro del estudio de esta patologia (8).
