Терапевтични показания:

Dopamine Hydrochloride, USP is indicated for the correction of hemodynamic imbalances present in the shock syndrome due to myocardial infarction, trauma, endotoxic septicemia, open-heart surgery, renal failure, and chronic cardiac decompensation as in congestive failure. Patients most likely to respond adequately to Dopamine Hydrochloride, USP are those in whom physiological parameters, such as urine flow, myocardial function, and blood pressure, have not undergone profound deterioration. Multiclinic trials indicate that the shorter the time interval between onset of signs and symptoms and initiation of therapy with blood volume correction and Dopamine Hydrochloride, USP, the better the prognosis. Where appropriate, blood volume restoration with a suitable plasma expander or whole blood should be accomplished prior to administration of Dopamine Hydrochloride, USP. Poor Perfusion of Vital Organs – Urine flow appears to be one of the better diagnostic signs by which adequacy of vital organ perfusion can be monitored. Nevertheless, the physician should also observe the patient for signs of reversal of confusion or reversal of comatose condition. Loss of pallor, increase in toe temperature, and/or adequacy of nail bed capillary filling may also be used as indices of adequate dosage. Clinical studies have shown that when Dopamine Hydrochloride, USP is administered before urine flow has diminished to levels of approximately 0.3 mL/minute, prognosis is more favorable. Nevertheless, in a number of oliguric or anuric patients, administration of Dopamine Hydrochloride, USP has resulted in an increase in urine flow, which in some cases reached normal levels. Dopamine Hydrochloride, USP may also increase urine flow in patients whose output is within normal limits and thus may be of value in reducing the degree of pre-existing fluid accumulation. It should be noted that at doses above those optimal for the individual patient, urine flow may decrease, necessitating reduction of dosage. Low Cardiac Output – Increased cardiac output is related to dopamine’s direct inotropic effect on the myocardium. Increased cardiac output at low or moderate doses appears to be related to a favorable prognosis. Increase in cardiac output has been associated with either static or decreased systemic vascular resistance (SVR). Static or decreased SVR associated with low or moderate movements in cardiac output is believed to be a reflection of differential effects on specific vascular beds with increased resistance in peripheral beds (e.g., femoral) and concomitant decreases in mesenteric and renal vascular beds. Redistribution of blood flow parallels these changes so that an increase in cardiac output is accompanied by an increase in mesenteric and renal blood flow. In many instances the renal fraction of the total cardiac output has been found to increase. Increase in cardiac output produced by dopamine is not associated with substantial decreases in systemic vascular resistance as may occur with isoproterenol. Hypotension – Hypotension due to inadequate cardiac output can be managed by administration of low to moderate doses of Dopamine Hydrochloride, USP which have little effect on SVR. At high therapeutic doses, dopamine’s alpha-adrenergic activity becomes more prominent and thus may correct hypotension due to diminished SVR. As in the case of other circulatory decompensation states, prognosis is better in patients whose blood pressure and urine flow have not undergone profound deterioration. Therefore, it is suggested that the physician administer Dopamine Hydrochloride, USP as soon as a definite trend toward decreased systolic and diastolic pressure becomes evident. Dopamine HCl should not be used in patients with pheochromocytoma. Dopamine HCl should not be administered to patients with uncorrected tachyarrhythmias or ventricular fibrillation.

----------
DOPAMINE HYDROCHLORIDE INJECTION, USP 200MG/5ML (40MG/ML)
DESCRIPTION
Dopamine Hydrochloride, USP a sympathomimetic amine vasopressor, is
the naturally occurring immediate
precursor of norepinephrine. Dopamine Hydrochloride, USP is a white to
off-white crystalline powder, which
may have a slight odor of hydrochloric acid. It is freely soluble in
water and soluble in alcohol. Dopamine
Hydrochloride, USP is sensitive to alkalies, iron salts, and oxidizing
agents. Chemically it is designated as 4-(2-
aminoethyl) pyrocatechol hydrochloride, and its molecular formula is
C8H11NO2 • HCl.
The structural formula is:
and the molecular weight is 189.64.
Dopamine Hydrochloride Injection, USP is a clear, practically
colorless, sterile, pyrogen-free, aqueous solution
of Dopamine Hydrochloride, USP for intravenous infusion after
dilution. Each milliliter of the 40 mg/mL
preparation contains 40 mg of Dopamine Hydrochloride, USP (equivalent
to 32.31 mg of dopamine base). Each
milliliter of the 80 mg/mL preparation contains 80 mg of Dopamine
Hydrochloride, USP (equivalent to 64.62
mg of dopamine base). Each milliliter of both preparations contains
the following: Sodium metabisulfite 9 mg
added as an antioxidant; citric acid, anhydrous 10 mg; and sodium
citrate, dihydrate 5 mg added as a buffer.
May contain additional citric acid and/or sodium citrate for pH
adjustment. pH is 3.3 (2.5 to 5.0).
Dopamine Hydrochloride Injection, USP must be diluted in an
appropriate sterile parenteral solution before
intravenous administration. (See DOSAGE AND ADMINISTRATION)
CLINICAL PHARMACOLOGY
Dopamine is a natural catecholamine formed by the decarboxylation of
3,4-dihydroxyphenylalanine (DOPA). It
is a precursor to norepinephrine in noradrenergic nerves and is also a
neurotransmitter in certain areas of the
central nervous system, especially in the nigrostriatal tract, and in
a few peripheral sympathetic nerves.
Dopamine produces positive
