Stavudine sustained release tablet

The present invention relates to a nucleoside reverse transcriptase inhibitors, particularly to sustained-release tablet and preparation method Division stavudine. Wherein the outer component in the sustained release film coat is stavudine and as a gel matrix core composition pharmaceutical excipients contained therein stavudine gel matrix core weight ratio of the pharmaceutical excipients as 1:0.68-2.32. The preparation method comprises a core production, coating and the like; object of the present invention is to solve the conventional release dosage forms of stavudine manufacturing equipment, process complexity, etc. Usually the preparation plant is difficult problems. The tablet production method is well known in the art hydrogel matrix sustained release film coating technology and techniques are combined, using a single time to avoid the drawbacks of their presence, the drug improved patient safety.
