DESCRIPTION Dopamine Hydrochloride and 5% Dextrose Injection, USP is a sterile, nonpyrogenic solution of Dopamine Hydrochloride, USP and Dextrose, USP in Water for Injection.

Uses
INDICATIONS AND USAGE Dopamine hydrochloride is indicated for the correction of hemodynamic imbalances present in the shock syndrome due to myocardial infarctions, trauma, endotoxic septicemia, open heart surgery, renal failure and chronic cardiac decompensation as in congestive failure. Where appropriate, restoration of blood volume with a suitable plasma expander or whole blood should be instituted or completed prior to administration of dopamine hydrochloride. Patients most likely to respond adequately to dopamine hydrochloride are those in whom physiological parameters, such as urine flow, myocardial function and blood pressure have not undergone profound deterioration.
Dosage
DOSAGE AND ADMINISTRATION Rate of Administration Dopamine Hydrochloride and 5% Dextrose Injection, USP is administered intravenously through a suitable intravenous catheter or needle. An IV drip chamber or other suitable metering device is essential for controlling the rate of flow in drops/minute. Each patient must be individually titrated to the desired hemodynamic and/or renal response with dopamine hydrochloride. In titrating to the desired increase in systolic blood pressure, the optimum dosage rate for renal response may be exceeded, thus necessitating a reduction in rate after the hemodynamic condition is stabilized. Administration of dopamine hydrochloride at rates greater than 50 mcg/kg/min has safely been used in advanced circulatory decompensation states.
Side Effects
ADVERSE REACTIONS The following adverse reactions have been observed, but there are not enough data to support an estimate of their frequency. Cardiovascular System ventricular arrhythmia atrial fibrillation ectopic beats tachycardia anginal pain palpitation cardiac conduction abnormalities widened QRS complex bradycardia hypotension hypertension vasoconstriction Respiratory System dyspnea Gastrointestinal System nausea vomiting Metabolic/Nutritional System azotemia Central Nervous System headache anxiety Dermatological System piloerection Other Gangrene of the extremities has occurred when high doses were administered for prolonged periods or in patients with occlusive vascular disease receiving low doses of dopamine HCl.
Interactions
Drug Interactions Cyclopropane or halogenated hydrocarbon anesthetics increase cardiac autonomic irritability and may sensitize the myocardium to the action of certain intravenously administered catecholamines, such as dopamine. This interaction appears to be related both to pressor activity and to the beta-adrenergic stimulating properties of these catecholamines, and may produce ventricular arrhythmias. Therefore, EXTREME CAUTION should be exercised when administering dopamine HCl to patients receiving cyclopropane or halogenated hydrocarbon anesthetics. Results of studies in animals indicate that dopamine-induced ventricular arrhythmias during anesthesia can be reversed by propranolol.
Warnings
WARNINGS Patients who have been treated with monoamine oxidase (MAO) inhibitors prior to the administration of dopamine hydrochloride will require substantially reduced dosage. See Drug Interactions , below. Evidence is inadequate for fully defining proper dosage and limitations for use in children. Contains sodium bisulfite, a sulfite that may cause allergic-type reactions including anaphylactic symptoms and life-threatening or less severe asthmatic episodes in certain susceptible people. The overall prevalence of sulfite sensitivity in the general population is unknown and probably low. Sulfite sensitivity is seen more frequently in asthmatic than in nonasthmatic people. CONTRAINDICATIONS Dopamine hydrochloride should not be used in patients with pheochromocytoma. Dopamine hydrochloride should not be administered in the presence of uncorrected tachyarrhythmias or ventricular fibrillation. Solutions containing dextrose may be contraindicated in patients with known allergy to corn or corn products.
Pregnancy
Pregnancy Teratogenic Effects Teratogenicity studies in rats and rabbits at dopamine HCl dosages up to 6 mg/kg/day intravenously during organogenesis produced no detectable teratogenic or embryotoxic effects, although maternal toxicity consisting of mortalities, decreased body weight gain, and pharmacotoxic signs were observed in rats. In a published study, dopamine HCl administered at 10 mg/kg subcutaneously for 30 days, markedly prolonged metestrus and increased mean pituitary and ovary weights in female rats.
Storage
HOW SUPPLIED Size (mL) mcg/mL NDC 250 1600 84549-007-02 Exposure of pharmaceutical products to heat should be minimized. Avoid excessive heat. Protect from freezing. It is recommended the product be stored at room temperature (25°C); brief exposure up to 40°C does not adversely affect the product. Avoid contact with alkalies (including sodium bicarbonate), oxidizing agents or iron salts.
