Metipranolol hydrochloride is primarily used in ophthalmology as a non-selective beta-adrenergic blocker to manage intraocular pressure. It is commonly prescribed in the form of eye drops to treat conditions such as glaucoma and ocular hypertension. By reducing the production of aqueous humor in the eye, it helps to lower pressure within the eyeball, thereby preventing damage to the optic nerve and preserving vision. This medication is often administered once or twice daily, depending on the severity of the condition and the patient's response to treatment. It is generally well-tolerated but may cause mild side effects such as eye irritation or blurred vision in some individuals. Patients with certain systemic conditions, such as asthma or heart problems, should use it with caution due to its potential systemic absorption.
