How is Carteolol classified in terms of pharmacological action?

Carteolol is classified as a non-selective topical beta-blocker. This means that it blocks both beta-1 and beta-2 adrenergic receptors, which is characteristic of non-selective beta-blockers. Its non-selectivity affects various tissues throughout the body, including the heart and the lungs. In the context of ocular pharmacology, carteolol is used in the treatment of elevated intraocular pressure in conditions like glaucoma.

The "topical" aspect refers to its application in the eye, highlighting its localized effect in ophthalmic treatments. By lowering intraocular pressure, carteolol helps manage conditions related to glaucoma without the systemic effects that might occur with oral beta-blockers.

Given its mechanism and application, classifying carteolol as a non-selective topical beta-blocker accurately reflects both its pharmacological action and therapeutic use.
