Methods and compositions for treatment of presbyopia, mydriasis, and other ocular disorders
The invention provides methods, compositions, and kits containing an alpha-adrenergic antagonist, such as phentolamine, for use in monotherapy or as part of a combination therapy to treat patients suffering from presbyopia, mydriasis, and/or other ocular disorders.
1. A method of treating mydriasis in a human patient due to said patient having received one or more of tropicamide, phenylephrine, or a pharmaceutically acceptable salt thereof, comprising administering to an eye of the human patient in need thereof a dosage of phentolamine mesylate to thereby treat the mydriasis, wherein the dosage is topically administered to the patient's eye as an eye drop, the dosage contains from about 0.4 mg to about 0.6 mg of phentolamine mesylate, and at two hours after the dosage of phentolamine mesylate is administered to the patient's eye there is at least a 30% reduction in pupil diameter in said eye of the patient measured under photopic conditions.
2. The method of claim 1 , wherein the mydriasis is due to the patient having received, phenylephrine or a pharmaceutically acceptable salt thereof.
3. The method of claim 1 , wherein the mydriasis is due to the patient having received (a) tropicamide or a pharmaceutically acceptable salt thereof and (b) phenylephrine or a pharmaceutically acceptable salt thereof.
4. The method of claim 1 , wherein the patient experiences at least a 1 mm reduction in pupil diameter when measured under photopic conditions relative to the diameter of the patient's pupil under the same photopic conditions but not having received said dosage.
5. The method of claim 2 , wherein the patient experiences at least a 1 mm reduction in pupil diameter when measured under photopic conditions relative to the diameter of the patient's pupil under the same photopic conditions but not having received said dosage.
6. The method of claim 1 , wherein the patient experiences at least a 2 mm reduction in pupil diameter when measured under photopic conditions relative to the diameter of the patient's pupil under the same photopic conditions but not having received said dosage.
7. The method of claim 2 , wherein the patient experiences at least a 2 mm reduction in pupil diameter when measured under photopic conditions relative to the diameter of the patient's pupil under the same photopic conditions but not having received said dosage.
8. The method of claim 1 , wherein at two hours after the dosage of phentolamine mesylate is administered to the patient's eye, the patient experiences at least a 2 mm reduction in pupil diameter when measured under photopic conditions relative to the diameter of the patient's pupil under the same photopic conditions but not having received said dosage.
9. The method of claim 2 , wherein at two hours after the dosage of phentolamine mesylate is administered to the patient's eye, the patient experiences at least a 2 mm reduction in pupil diameter when measured under photopic conditions relative to the diameter of the patient's pupil under the same photopic conditions but not having received said dosage.
10. The method of claim 1 , wherein the patient experiences an increase in eye redness of no more than two grades measured using the CCLRU Redness Grading Scale compared to the patient's level of eye redness without receiving said dosage of phentolamine mesylate.
11. The method of claim 7 , wherein the patient experiences an increase in eye redness of no more than two grades measured using the CCLRU Redness Grading Scale compared to the patient's level of eye redness without receiving said dosage of phentolamine mesylate.
12. The method of claim 1 , wherein the patient experiences no burning sensation due to the dosage of phentolamine mesylate.
13. The method of claim 7 , wherein the patient experiences no burning sensation due to the dosage of phentolamine mesylate.
14. The method of claim 1 , wherein at two hours after the dosage of phentolamine mesylate is administered to the patient's eye, change in accommodation in the patient's eye is ≥−1 diopters relative to baseline.
15. The method of claim 7 , wherein at two hours after the dosage of phentolamine mesylate is administered to the patient's eye, change in accommodation in the patient's eye is ≥−1 diopters relative to baseline.
16. The method of claim 1 , wherein a therapeutic benefit is observed within 1 hour after administering the dosage of phentolamine mesylate.
17. The method of claim 7 , wherein a therapeutic benefit is observed within 1 hour after administering the dosage of phentolamine mesylate.
18. The method of claim 1 , wherein the dosage contains about 0.5 mg of phentolamine mesylate.
19. The method of claim 2 , wherein the dosage contains about 0.5 mg of phentolamine mesylate.
20. The method of claim 7 , wherein the dosage contains about 0.5 mg of phentolamine mesylate.
21. The method of claim 1 , wherein the eye drop is a liquid aqueous ophthalmic formulation containing about 0.5 mg of phentolamine mesylate.
22. The method of claim 7 , wherein the eye drop is a liquid aqueous ophthalmic formulation containing about 0.5 mg of phentolamine mesylate.
23. The method of claim 1 , wherein dosage is an ophthalmic solution containing water, mannitol, sodium acetate, and about 0.5 mg phentolamine mesylate.
24. The method of claim 1 , wherein all phentolamine mesylate is administered to the eye of the patient once the patient has completed an eye examination in which the one or more of tropicamide, phenylephrine, or a pharmaceutically acceptable salt thereof was administered to the patient's eye.
