Abstract

The invention discloses a procaine injection which is prepared from the following bulk pharmaceutical chemicals: procaine, xylitol, 30-70% ethanol and polyethylene glycol 400. The preparation method of the procaine injection comprises: taking procaine of a prescription amount; dissolving the procaine with ethanol; adjusting pH value; adding the xylitol; then, adding the polyethylene glycol 400 and propylene glycol; diluting to reach the whole amount; stirring; adjusting the pH value; filtering; splitting; and sterilizing by circulated steam. The injection has stable quality and high bioavailability and is especially suitable for patients with diabetes.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, specifically, a procaine injection and a preparation method thereof. Background technique [0002] Procaine is an amide local anesthetic that can interact with the axoplasmic medial receptors of the sodium channel on the nerve cell membrane, block the influx of sodium ions, and reversibly block the impulse conduction of nerve fibers. It has the characteristics of fast action, wide diffusion, strong penetrating power, and no obvious expansion of blood vessels. Menthol is a saturated cyclic alcohol extracted from the traditional Chinese medicine Peppermint, which can interact with nerve cell membrane lipids, causing changes in the membrane lipid structure, swelling the membrane, narrowing the sodium channel of the cell membrane, reducing the influx of sodium ions, and nerve cells cannot Generate a spreading action potential, resulting in local nerve blockade. Pharmacokinetics:...
