Acetazolamide (ACZ), a carbonic anhydrase inhibitor (CAI), and other oral CAIs have been an integral part of antiglaucoma therapy for > 40 years. ACZ is used orally for the reduction of intraocular pressure in patients suffering from glaucoma. However, this treatment leads to unpleasant systemic side effects. The answer to the undesirable effects of ACZ is the topical delivery of this drug into the eye, where it could elicit its physiological action. However, the development of a topical formulation of ACZ is limited by its poor ocular bioavailability, which can be largely attributed to its poor penetration coefficient and poor biphasic solubility.This review offers an overview of different approaches to delivering ACZ to the eye, highlighting the potential of the ternary system ACZ:HP-beta-CD:TEA as a tool for formulating aqueous ACZ eye drop solutions.A critical analysis is provided to highlight the key issues to design formulations containing hydrophilic cyclodextrins.The ACZ:HP-beta-CD:TEA complex is an important new approach to improve the ocular bioavailability of this drug. This approach may be applied to other CAIs in the future.
