Abstract
A tablet for oral adminstration of a sustained-release medication is formed by compressing microcapsules of the active principle. The microcapsules are of a size range between about 5 and 300 microns and comprise particles of active principle coated with a thin, flexible layer of sustained release material. The sustained-release material contains about 15-30% by weight thereof of plasticizer and is coated in an amount corresponding to 10-25% of the weight of the active material. Excipients causing disintegration of the tablet after administration can be uniformly mixed with the microcapsules prior to compression.
