Abstract

The present invention is a process to produce an oral sustained release pharmaceutical composition of felodipine. The process includes mixing the felodipine with ionic surfactant or water-soluble polymer as solubilizers, sustained-effect excipient and diluents. If necessary, granulate the mixture with solvent, and dry to a specified moisture content, the granules are lubricated with lubricants. Compress the mixture or granules to pharmaceutical tablets, or fill in the hard capsules. If necessary, one layer of light-resistant film coating is applied to the tablet. This procedure could increase the dissolved rate of the insoluble drug of felodipine, maintain the sustained release rate and high activity of bioavailability.

The rotation speed was measured at 5 rpm, and the elution rate versus time was measured. The results are shown in Table 1, Figure 1 and Figure 2. From Table 1, it is known that the pharmaceutical preparations of the first embodiment to the fifth embodiment are commercially available with an equal amount of the sustained release tablet of felopimine, in the case of hydrochloric acid solution 0.1% oleic acid sorbitol vinegar, It has a sustained release effect, and its dissolution rate is above 75% at 2 hours. In the control group, the six drug-containing products have a dissolution rate of only 6% at 20 days, indicating that the product of the present invention can be improved (4) Bathing rate and the effect of sustained release.
