The retention of oral drug dosage forms in the stomach is improved by using swellable dosage forms that are shaped in a manner that will prevent them from inadvertently passing through the pylorus as a result of being in a particular orientation. The planar projection of the shape is one that has two orthogonal axes of different lengths, the longer being short enough to permit easy swallowing prior to swelling while the shorter is long enough within one-half hour of swelling to prevent passage through the pylorus.
