Abstract

The present invention provides a kind of new penciclovir preparation form, penciclovir gel. The penciclovir gel consists of penciclovir, matrix, pH regulator and water. The preparation process of the penciclovir gel includes dissolving penciclovir and pH regulator in water through heating and stirring to obtain penciclovir solution; mixing with the hydrophilic matrix; adding pure water to required amount; and vacuumizing to eliminate bubble, filling and sealing to obtain penciclovir gel product. Compared with available cream, the penciclovir gel is comfortable and has no greasy feeling.

Description

technical field [0001] The invention relates to a gel preparation, in particular to a pharmaceutical preparation containing penciclovir and a preparation method thereof. Background technique [0002] Penciclovir is a fully synthetic acyclovir antiviral drug. Penciclovir has inhibitory activity against HSV-1, HSV-2, VZV and E-B viruses, but is weak against cytomegalovirus (CMV). In cells infected with HSV-1, HSV-2 and VZV, penciclovir generates monophosphate under the action of viral thymidine kinase, which is further phosphorylated by cellular enzymes to generate the active metabolite penciclovir triphosphate Esters (PCV-TP). When PCV-TP in cells reaches a high concentration, it interacts with viral DNA polymerase, thereby inhibiting DNA synthesis. Penciclovir is a highly effective, safe and selective antiviral drug. [0003] Herpes virus infection is a common and frequently-occurring disease, and the recurrence rate of cold sores is relatively high. According to reports...
