METAPROTERENOL METARAMINOL METHYLPREDNISOLONE Name/Class: METAPROTERENOL (Alupent)/Sympathomimetic Bronchodilator Description: Metaproterenol is a synthetic sympathomimetic amine, similar to isoproterenol that causes smooth muscle relaxation of the bronchial tree, decreasing airway resistance, facilitating mucus drainage, and increasing vital capacity. Indications: Bronchospasm, as in asthma and COPD. Contraindications: Hypersensitivity to sympathomimetic agents, tachydysrhythmias, and hyperthyroidism. Precautions: Elderly, hypertension, coronary artery disease, and diabetes. Dosage/Route: 0.65 mg via metered dose inhaler (2 sprays); 0.2 to 0.3 mL in 2.5 to 3 mL NS via nebulizer. Ped: 0.1 to 0.2 mL/kg (5% solution) in 2.5 to 3 mL NS via nebulizer. Name/Class: METARAMINOL (Aramine)/Sympathomimetic Description: Metaraminol is a sympathomimetic similar to norepinephrine but less potent, with gradual onset and longer duration. It causes systemic vasoconstriction and increased cardiac contraction strength, increasing blood pressure and reducing flow to the kidneys. Indications: Hypotension in a normovolemic patient. Contraindications: Hypovolemia; MAO inhibitor therapy; peripheral or mesenteric thrombosis; pulmonary edema; cardiac arrest; untreated hypoxia, hypercapnia, and acidosis. Precautions: Digitalized patients, hypertension, thyroid disease, diabetes, hepatic impairment, malaria. Dosage/Route: 100 mg/500 mL D5W or NS, titrated to blood pressure: 5 to 10 mg IM. Name/Class: METHYLPREDNISOLONE (Solu-Medrol)/Corticosteroid, Antiinflammatoty Description: Methylprednisolone is a synthetic adrenal corticosteroid, effective as an antiinflammatory and used in the management of allergic reactions and in some cases of shock. It is sometimes used in the treatment of spinal cord injury. Indications: Spinal cord injury, asthma, severe anaphylaxis, COPD. Contraindications: No major contraindications in the emergency setting. Precautions: Only a single dose should be given in the prehospital setting. Dosage/Route: Asthma/COPD/anaphylaxis: 125 to 250 mg IV/IM. Ped: 1 to 2 mg/kg/dose IV/IM. Spinal cord injury: 30 mg/kg IV over 15 min, after 45 min an infusion of 5.4 mg/kg/hr.
