A solid pharmaceutical composition in which the carrier consists essentially of hydroxypropylmethylcellulose, or hydroxypropylmethylcellulose admixed with up to about 20% ethylcellulose, is prepared by compressing a mixture comprising one therapeutic agent and the hydroxypropylmethylcellulose powder which has been humidified to a moisture content of from about 5 to about 25% by weight at a low compression pressure. The solid pharmaceutical composition obtained will release the active ingredient contained therein evenly over a prolonged period, e.g. from about 1 to 8 hours.
