Problems solved by technology

[0003] Photosensitizers (photochemotherapeutic agents) in the prior art are not always very satisfactory for photochemotherapy, the probability of relapse is extremely high in a short period of time, and the stability of photochemotherapeutic agents is not very good during storage before use. Therefore need improved photochemotherapeutic agent, improve the effect of adjuvant therapy, the present invention aims at solving this technical problem, provides a kind of ointment for photochemical adjuvant therapy and its preparation method and application

Abstract

The invention relates to a medical ointment, in particular to an ointment for photochemical adjuvant therapy and a preparation method and application thereof. The ointment is prepared from, by weight, 5-8 parts of Carbomer, 4-8 parts of glycerol, 12-16 parts of ethyl p-hydroxybenzoate, 1-10 parts of 5-methyl aminolevulinate, 1-3 parts of medical essence and 20-40 parts of ointment matrix. The ointment has the advantages that when the ointment is used for photochemical adjuvant therapy, the treatment effect is good; after patients suffering from acne or condyloma acuminate use the ointment for adjuvant therapy, the relapse rate is extremely low. By means of the preparation method of the ointment, processing efficiency is high, product quality is stable, controllability is good, and cost is low.

Description

technical field [0001] The invention relates to a medical ointment, in particular to an ointment for photochemical auxiliary therapy and its preparation method and application. Background technique [0002] Photochemotherapy, or photodynamic therapy, is a technique used to treat various skin or other epithelial or mucosal abnormalities, especially cancerous or precancerous lesions and certain non-malignant lesions such as acne, genital warts. Photochemotherapy involves the application of a photosensitizer to an affected part of the body followed by light exposure to activate the photosensitizer and convert it into a cytotoxic form that kills the affected cells or reduces their proliferative potential. [0003] Photosensitizers (photochemotherapeutic agents) in the prior art are not always very satisfactory for photochemotherapy, the probability of relapse is extremely high in a short period of time, and the stability of photochemotherapeutic agents is not very good during st...
