Abstract

A dry sustained release oral dosage formulation of theophylline and a method of orally administering theophylline is disclosed. The oral formulation is comprised of a capsule which includes upper and lower parts which are connectible and easily separable from each other, and a plurality of micropellets present in the capsule. The micropellets provide sustained release of theophylline when taken by a patient and are comprised of inner seeds coated with a mixture of theophylline and polyvinylpyrrolidone which is further coated with a mixture of ethylcellulose and hydroxypropylcellulose. The oral dosage formulation is administered by separating the upper and lower parts of the capsule and placing the micropellets on a food which is preferably soft to the extent of not requiring chewing and then eating the food with the micropellets thereon. The micropellets have sufficient size so that they can be seen, but are sufficiently small so that they are not easily detected in the mouth in combination with the food and can be swallowed without difficulty.
