Abstract: Solid pharmaceutical compositions suitable for the oral delivery of pharmacologically active agents, e.g. peptides, comprising a therapeutically-effective amount of a pharmacologically active agent; a crospovidone or povidone; and a delivery agent for said pharmacologically active agent are disclosed. The compositions provide excellent oral bioavailability of pharmacologically active agents, particularly calcitonin.
