Hypromellose is a versatile semi-synthetic polymer used as a film-former, binder, thickener, and controlled-release matrix in pharmaceutical and nutraceutical dosage forms.
In tablets and capsules, HPMC provides robust film coatings, sustained or controlled-release matrices, and improved mechanical strength and stability.
It is the primary material for many hard and soft vegetarian capsules, offering excellent compatibility and pH-independent solubility.
In ophthalmic and topical preparations, HPMC enhances viscosity, mucoadhesion, and residence time, improving patient comfort and drug performance.
Its non-ionic nature, wide viscosity grades, and strong regulatory acceptance make HPMC one of the most important modern excipients.
