Abstract

The invention discloses valganciclovir combined tablets and a preparation method thereof, and belongs to the technical field of pharmacy. The valganciclovir combined tablets comprise the following components in parts by mass: 10-15 parts of valganciclovir hydrochloride, 15-25 parts of resveratrol, 5-8 parts of propolis powder, 30-40 parts of corn starch, 20-25 parts of filler and 0.3-0.5 part of alubricant. The preparation method of the valganciclovir combined tablets comprises the steps of firstly, mixing, crushing and sieving the valganciclovir hydrochloride and the resveratrol to prepare main medicine powder, and crushing and sieving the other components respectively for use; adding the main medicine powder, the propolis powder, the corn starch and the filler into deionized water in sequence to prepare a soft material, then conducting extrusion granulation, drying and granule straightening, and conducting mixing and tabletting on granules and the lubricant to prepare the valganciclovir combined tablets. The anti-CMV efficacy of the combined tablets is improved, and the pharmacy cost is low; and the uniform degree of specifications of the medicines prepared according to the preparation method is high, and the preparation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of pharmacy, in particular to a valganciclovir combination tablet and a preparation method thereof. Background technique [0002] Cytomegalovirus (CMV) belongs to the herpes virus family. The virus is in a resting state in individuals with normal immune function, but when the immune function is impaired (such as AIDS patients, organ transplantation and bone marrow transplantation, receiving immunosuppressive patients, etc.), the virus can cause serious illness. CMV infection occurs through direct contact with infected tissue or bodily fluids (such as saliva, blood, or urine). The routes of transmission are very extensive, and the most common ones are intrauterine, cervical secretion or breast milk transmission, close contact with young children in the intensive care unit, and sexual contact. The most common condition of CMV in AIDS patients is CMV retinitis, an eye infection that can lead to blindness. ...
