<p>A process for producing sustained-release tablets which comprises tableting a mixture of water-insoluble cellulose or a derivative thereof, a drug and a wax and heat-treating the obtained tablets; and a process for producing sustained-release tablets and enteric tablets which comprises heat-treating a mixture of water-insoluble cellulose or a derivative thereof, a drug and a wax and tableting the mixture thus treated. The above processes can provide sustained-release tablets from which the drug is sustainedly released at a nearly constant of arbitrary rate and which can retain the drug activity for long and enteric tablets from which the drug is released not in the stomach but in the intestine.</p> |
