Abstract

The invention discloses gel for treating herpes zoster. The gel is prepared from the following raw materials in percentage by weight: 2-4 percent of acyclovir, 1-3 percent of lidocaine hydrochloride, 0.05-0.15 percent of tacrolimus, 0.04-0.06 percent of vitamin B12, 0.5-1.5 percent of a gel substrate, 1-1.5 percent of a neutralizer, 4-6 percent of a moisturizer, 25-35 percent of a solvent, 1-3 percent of a solubilizer, 0.5-1.5 percent of an absorption enhancer and the balance of water. The gel substrate is any one or more of carbopol 940, hydroxypropyl methyl cellulose, alginate, gelatin or starch; the neutralizer is triethanolamine or sodium hydroxide; the moisturizer is glycerin; the solvent is ethyl alcohol; the solubilizer is tween-80; the absorption enhancer is laurocapram. The invention also discloses a preparation method of the gel. All medicine components in the gel have a synergistic effect, the dosage of the medicines can be reduced, and the adverse reaction of the medicines is reduced.

Description

technical field [0001] The invention relates to a gel for treating herpes zoster and a preparation method thereof, belonging to the technical field of pharmaceutical preparations. Background technique [0002] Shingles is a skin disease caused by a virus that can occur anywhere on the body. It is more likely to occur in the distribution areas of the trigeminal nerve, vertebral nerve, intercostal nerve and lumbosacral nerve. Because it invades the nerve, the patient suffers from unbearable pain, so timely treatment is particularly important. [0003] Clinically, antiviral drugs for the treatment of herpes zoster mainly include ribavirin, acyclovir, valaciclovir, valacyclovir, and penciclovir. In the process of treating herpes zoster, the above-mentioned drugs exert their medicinal effects by directly acting on the virus, and exhibit antiviral activity by inhibiting the replication of viral DNA or acting on enzymes related to DNA replication. [0004] However, viruses have s...
