Two new sulfonamides incorporating arylsulfonylureido moieties were complexed with gamma cyclodextrin (gamma-CD), hydroxypropyl-gamma cyclodextrin (HP gamma-CD), hydroxypropyl-beta cyclodextrin (HP beta-CD) and hydroxyethyl-beta cyclodextrin (HE beta-CD) in order to obtain drug formulations with effective topical intraocular pressure (IOP) lowering effects, in an animal model of glaucoma. The HP gamma-CD was the best solubilizing agent for the two sulfonamides and its complexes were characterized in detail and administered to rabbits with eye hypertension of 45-50 mm Hg. The peak IOP lowering was observed after 1 h post-administration and was of 36-37 mm Hg. A low IOP pressure (of around-35 mm Hg) was then maintained for the next 24 h post-administration, which has not been observed before with any IOP lowering drug. (c) 2015 Elsevier Ltd.
