Hypotensive lipid and timolol compositions and methods of using same
New compositions for and methods of treating ocular hypertension provide for effective treatment of ocular hypertension often using reduced concentrations of active components. Such compositions include a timolol component and a hypotensive lipid component. The present compositions and methods are relatively straightforward, can be easily produced, for example, using conventional manufacturing techniques, and can be easily and conveniently practiced, for example, using application or administration techniques or methodologies which are substantially similar to those employed with prior compositions used to treat ocular hypertension.
1. An aqueous composition suitable for ocular administration, the composition comprising 0.68% (w/v) timolol maleate, 0.03% (w/v) bimatoprost, and benzalkonium chloride in a single composition, wherein the composition is effective in reducing intraocular pressure when applied to an eye.
2. The composition of claim 1 , wherein administration of the composition reduces one or more side effects as compared to the administration of another composition comprising 0.03% (w/v) bimatoprost without timolol maleate.
3. The composition of claim 2 , wherein the reduced side effect is conjunctival hyperemia.
4. The composition of claim 1 , wherein the composition further comprises a citrate buffer, a phosphate buffer, and has a pH of about 7.3.
