Repair and desensitization injection and preparation method thereof

Abstract

The invention relates to a repair and desensitization injection and a preparation method thereof. The repair and desensitization injection is prepared from the following raw materials in parts by weight: 98-100 parts of water for injection, 0.15-0.25 part of lecithin for injection, 0.25-0.35 part of glycerol for injection, 0.75-0.85 part of methylene blue, 0.03-0.04 part of paeonol and 0.25-0.35 part of phenoxyethanol. The repair and desensitization injection mainly reduces and delays pleasant sensation of a frenum, a urethra and a glans penis at the same time, and also can play a good repairing role on chronic trauma caused by frequent and excessive stretching of a penis. The preparation method is simple and easy to control, and facilitates large-scale production.

Description

technical field [0001] The invention belongs to the field of medicines, and in particular relates to a repairing hyposensitivity injection and a preparation method thereof. Background technique [0002] Premature ejaculation (PE) is one of the most important problems in men's health. According to statistics, 20-40% of adult men worldwide suffer from different degrees of PE. Because the disease involves personal privacy, many patients avoid medical treatment. The true incidence may be higher. The pathogenesis of PE has not yet been fully elucidated, and its occurrence may be related to psychological factors and sexual organ factors. At present, the clinical treatment is mostly oral serotonin reuptake inhibitors, adrenergic α receptor antagonists, and phosphodiesterase type 5. Drugs or traditional Chinese medicines are the main ones, but most of them have obvious side effects, are relatively expensive, and have poor curative effects.

Problems solved by technology

The theory of penile dorsal neurotomy originates from the "penile hypersensitivity theory", which believes that blocking the conduction of some nerve fibers can reduce the sensitivity of the glans, thereby prolonging the intravaginalejaculatory latency time (IELT) and improving the clinical symptoms of PE , but it has been confirmed by a large number of clinical studies that the total effective rate of dorsal penis neurotomy is only 73.2%, which is not suitable for all PE patients. The treatment method has high limitations, and there are many postoperative adverse reactions. 8.1% of total PE patients undergoing dorsal penile neurotomy (References: Tullii RE, Guillaux CH, Vaccari R, et al.

[0004] Based on the above theoretical basis and the possible adverse consequences of surgery, new research is still needed
