Abstract
Solid unit dosage medicaments which are suitable for use in animals and humans are prepared with hydroxypropyl cellulose as the primary formulating excipient. These medicaments are particularly suitable for ophthalmic use since they are slowly but completely water soluble when they are inserted in the cul-de-sac of the eye and thus provide for a convenient means of prolonged treatment of the eye with concomitant reduced dosing frequency.
