Carteolol is an active substance belonging to the group of hydrophilic, non-selective beta-blockers, used in the form of eye drops for the treatment of elevated intraocular pressure and glaucoma. It is believed to lower pressure by reducing aqueous humour secretion. During treatment, it must be noted that the active substance can be absorbed into the systemic circulation. Therefore, adverse effects may occur, affecting, among others, the respiratory tract and the cardiovascular system.
Carteolol (ATC S01ED05) lowers intraocular pressure presumably by reducing aqueous humour secretion. The exact mechanism of action is, however, not fully known. Carteolol is a hydrophilic, non-selective beta-blocker with intrinsic sympathomimetic activity. As such, it has the potential, among other effects, to cause bronchoconstriction and to lower heart rate and blood pressure. Carteolol has minimal local anaesthetic activity compared to other agents in this class.
