摘要

Stable pharmaceutical compositions containing 8-chloro-6,11-dihydro-11-(4-piperidylidene)-5H-benzo[5,6]cyclohepta[1,2-b]pyridine ("DCL") and a DCL protective amount of a pharmaceutically acceptable basic salt such as calcium dibasic phosphate and an amount of at least one disintegrant, preferably two disintegrants such as microcrystalline cellulose and starch sufficient to provide dissolution of at least about 80% by weight of the pharmaceutical composition in about 45 minutes and suitable for oral administration to treat allergic redactions in mammals such as man are disclosed.
