Abstract

The invention discloses injecta containing milrinone and a preparation method of the injecta. The injecta contains the components of 1g / L of milrinone, 0.5-2g / L of amiodarone hydrochloride, 0.8-1.0% (w / v) of sodium chloride and 4-10% (v / v) of ethanol. The dosage of a pharmaceutically acceptable acidic material is that pH of the injecta is 3.0-5.0, and the balance is injection water. According to the injecta disclosed by the invention, the symptoms of hemorrhagic shock can be effectively improved; generation of anaerobic respiration lactic acid is restrained under an anaerobic condition; the injecta has a good function on protecting liver and kidney, and the survival time of a sufferer is obviously prolonged.

Description

technical field [0001] The invention belongs to the technical field of western medicine preparations, and in particular relates to an injection containing milrinone and a preparation method thereof. Background technique [0002] Milirinone is the general name of 1,6-dihydro-2-methyl-6-oxo-[3,4`-bispyridine]-5-carbonitrile, which is non-digitalis and non-catecholamine strong Heart medicine, an alternative to Amrinone. Experiments have shown that milrinone can increase myocardial contractility by selectively inhibiting phosphodiesterase III in cardiomyocytes, increasing intracellular cyclic adenosine monophosphate (C-AMP), and changing the transport of intracellular and extracellular calcium. Milrinone has a direct relaxing effect on vascular smooth muscle, which can reduce the preload and afterload of the heart. Milrinone can significantly reduce systemic vascular resistance, pulmonary vascular resistance, mean pulmonary arterial pressure and pulmonary capillary wedge press...
