Abstract

The invention provides a sulfadiazine rapid release tablet. The sulfadiazine rapid release tablet comprises a sulfadiazine active ingredient as well as one or more of a filler, a disintegrating agent, a binding agent, a lubricating agent, a flow aid, a flavouring agent, a smell reducing agent and a colouring agent and further comprises a release accelerator which can promote release of the active ingredient. The release accelerator can be selected from the following substances: lauryl sodium sulphate, poloxamer, Twain, cetyltriethyl ammonium bromide, sodium laurylsulfate, sodium stearyl sulfonate, polyoxyethylene higher aliphatic alcohol, sucrose ester, sorbitol fatty ester, soybean phospholipil, alginic acid, sodium alga acid and aluminium-magnesium silicate colloid, and usage amount of the release accelerator accounts for 0.1-5% of the total weight of the sulfadiazine rapid release tablet.

Description

technical field [0001] The invention relates to a solid oral preparation for the treatment of cardiovascular diseases, such as myocarditis, cardiomyopathy, ischemic encephalopathy and other diseases, in particular to a rapid-release sulfadiazine tablet, and the invention also relates to a sulfadiazine tablet of the tablet. Preparation. Background technique [0002] Sulfadiazine immediate-release tablets belong to the middle-acting sulfonamides, which are effective against non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Klebsiella, Salmonella, Shigella and other intestinal bacteria. Bacteriaceae, Neisseria gonorrhoeae, Neisseria meningitidis, Haemophilus influenzae have antibacterial activity, and also have antimicrobial activity in vitro against Chlamydia trachomatis, Nocardia asteroidis, Plasmodium and Toxoplasma gondii. Sulfonamides are broad-spectrum antibacterial drugs, but because many common clinical path...
