Hypromellose (INN), short for hydroxypropyl methylcellulose (HPMC), is a semisynthetic, inert, viscoelastic polymer used as eye drops, as well as an excipient. Hydroxypropyl methylcellulose (HPMC) or hypromellose refers to soluble methylcellulose ethers. Hypromellose, also commonly known as hydroxypropyl methycellulose (HPMC) is a coating agent and film-former used as an inactive. Such is the case for HPMC hard capsules. It can be used as the binder of tablets, the thickener for eye drops, and as topical preparations such as the protective colloid for gels or ointments,.
