Ophthalmic compositions containing a nitric oxide donor
View Patent ↗The present invention relates to compositions comprising a 4-nitrooxybutan-1-ol alkyl ester as nitric oxide donor. More specifically, the invention relates to compositions comprising 4-nitrooxybutan-1-ol alkyl ester as a nitric oxide donor and an ophthalmic drug, useful in controlling elevated intraocular pressure associated with glaucoma or ocular hypertension associated with other diseases or conditions. The invention is also directed to methods of controlling intraocular pressure utilizing said compositions.

4. A composition according to claim 1 wherein the carbonic anhydrase inhibitor is selected from dorzolamide, brinzolamide.
5. A composition according to claim 1 wherein the beta blocker selected from timolol, carteolol, betaxolol, levobunolol or metipranolol.
6. A composition according to claim 1 wherein the alpha-adrenergic agonist is selected from brimonidine, apraclonidine, epinephrine or dipivefrin.
7. A composition according to claim 1 wherein the prostaglandin analogue is selected from bimatoprost, latanoprost, travoprost, unoprostone isopropyl or tafluprost.
8. A composition according to claim 1 wherein the cholinergic agonist selected from pilocarpin, carbacol or echothiophate.
9. A composition according to claim 1 wherein the non-steroidal anti-inflammatory drug is selected from bromfenac, flurbiprofen, naproxen or ketoprofen.
10. A composition according to claim 1 wherein the steroidal anti-inflammatory drug is selected from dexamethsone, fluocinolone acetonide, triamcinolone acetonide, budesonide or prednisolone.
11. Pharmaceutical formulation comprising a composition according to claim 1 and at least an ophthalmically acceptable excipient.
12. A pharmaceutical formulation comprising a nitric oxide donor of formula (I) or stereoisomers thereof:
RC(O)O—(CH 2 ) 4 —ONO 2 (I)
