Abstract
Background: Glaucomas are a group of optic neuropathies characterized by progressive degeneration of retinal ganglion cells. Degeneration of these nerves results in cupping, a characteristic appearance of the optic disc and visual loss. Glaucoma can remain asymptomatic until it is severe, resulting in a high likelihood that the number of affected individuals is much higher than the number known to have it. Without adequate treatment glaucoma can progress to visual disability and eventual blindness which is irreversible. Many types of glaucoma are usually controlled with daily medical treatment consisting of eye drops lowering IOP. Some do this by reducing the amount of aqueous fluid the eye makes. Others reduce pressure by helping aqueous fluid flow better through the drainage angle. A generic medicine is defined as a product having the same qualitative and quantitative composition in active ingredients, as well as the same pharmaceutical form, as the reference medicine and whose bioequivalence has been shown by adequate bioavailability studies, also its low price makes it more affordable.
Aim of the Work: To evaluate intra ocular pressure control and compliance of the patient using a generic prostaglandins eye drops in comparison to a brand one in the management of glaucoma patients and its safety profile, to determine the value of the generic drug in glaucoma management.
Patients and Methods: This is a prospective interventional cross over study was done on 30 patients recruited from Glaucoma Clinic of National Eye Center, Rod El Farag from January 2019 to July 2019.
Results : The mean baseline IOP of both main groups on day 0 was 23.9 ± 3.3 mmHg at 9 AM , 23.6 ± 2.7 mmHg at 1 PM , 23.6 ± 2.3 mmHg at 6 PM before treatment with original or generic latanoprost (P = 1). Both treatments reduced the IOP from baseline (day 0 of each drug) at each time-point, and for the three diurnal IOP measurements at 3 months. Original latanoprost had a greater efficacy than generic latanoprost after 3 months, Original Latanoprost reduced the IOP after 3 months of treatment by -8.6 ± 0.84 mmHg at 9.00 AM , -
7.4 ± 1.2 mmHg at 1.00 PM hours and -6.4 ± 1.8 mmHg at 6.00 PM, While Generic latanoprost reduced IOP after 3 months by -7.03 ± 0.95, -5.8 ± 1.1 and -4.9 ± 1.8 mmHg, respectively.
Conclusion: Original latanoprost has a tendency of better efficacy and tolerability with low incidence of conjunctival hyperaemia and ocular irritation compared with the generic latanoprost in management of open angle glaucoma patient.
