Abstract
The invention discloses a pidotimod orally disintegrating tablet which includes, by mass, 50-90% of pidotimod main drug, 5-10% of a disintegrating agent, 5-30% of a filling agent, 1-5% of a corrigent and 0.05-2% of a lubricant. The invention also discloses a preparation method of the pidotimod orally disintegrating tablet. The method includes the steps of: 1) sieving a pidotimod raw material through a 60-mesh sieve; 2) uniformly mixing the sieved raw material with the filling agent, the disintegrating agent and the corrigent in a manner of increment by equal quantity; 3) adding the lubricant to the mixture, uniformly mixing the components, and tabletting the mixture, wherien each tablet is 500-600 mg in weight and is 20-40 N in hardness. The pidotimod orally disintegrating tablet is free of water for taking and can be disintegrated and dissolved in saliva. Through preparation technology, bad smell of medicine can be covered effectively. The tablet can be packaged by common aluminum plastic package and is convenient to use. The tablet improves compliance during long-time use of patients and is especially suitable for the elders and children.
