摘要 |
The present invention is an improved pharmaceutical composition useful in the treatment of colds, sinus and allergies comprising an unstable antihistamine such as phenindamine that is stabilized in a non-aqueous, inert carrier system. More specifically, the phenindamine is stabilized in a mineral oil/fumed silica particle matrix which so stabilizes the compound that additional, otherwise reactive drugs such as analgesics, decongestants and expectorants can be incorporated for a more effective, multi-system formula. |
