Preparation of Controlled-Release Tablets of Sasanquasaponin
Abstract:
he controlled-release tablets of sasanquasaponin (SQS) were prepared by using SQS, hydroxypropyl methyl cellulose, ethylcellulose and lactose as the main drug, skeleton material and fillers, respectively. The effects of the dosage of hydroxypropyl methyl cellulose and ethylcellulose on release rate were studied. The release rate curve of the data of the prescription of the controlled-release tablets of SQS were fitted as zero order, one order and Higuchi equation. The release rate of the controlled-release tablets of SQS were controlled by controlling the dosage of hydroxypropyl methyl cellulose and ethylcellulose. The influence of the dosage of hydroxypropyl methyl cellulose on release rate of the controlled-release tablets of SQS was the biggest factor. The prescription of the controlled-release tablets of SQS contains in each piece: SQS 200mg, hydroxypropyl methyl cellulose 40mg, ethylcellulose 30mg, lactose 30mg. The controlled-release tablets of SQS release SQS by slowness and constant in 12h.
