Hydroxypropyl methyl cellulose (HPMC) is a common ingredient in eye drops used to treat various eye conditions. HPMC is a type of polymer that is derived from cellulose and is used as a thickening agent, viscosity modifier, and lubricant in eye drops.
In eye drops, HPMC helps to improve the viscosity and retention time of the eye drops on the eye’s surface, which enhances the drug’s effectiveness. It also acts as a lubricant, which can help to relieve dry eye symptoms and reduce discomfort.
HPMC eye drops are typically used to treat conditions such as dry eye syndrome, allergic conjunctivitis, and other eye irritations. They are also commonly used as a lubricant during eye surgery.
HPMC eye drops are generally safe for use, but as with any medication, there can be potential side effects. These can include temporary blurred vision, eye irritation, and stinging or burning sensations in the eyes.
It is important to follow the instructions on the eye drop package carefully and to consult with a healthcare professional if you experience any unusual symptoms or discomfort after using the drops.
