[Progress of anti-glaucoma fixed combination formulation].

ABSTRACT

Glaucoma is a common cause of visual impairment and irreversible blindness. Medication is important in the management of glaucoma, especially in primary open-angle glaucoma. Combination drug therapy is needed because single drug therapy can not always control the intraocular pressure effectively to a safe level in glaucoma patients with higher baseline intraocular pressure. Traditional unfixed combination therapy of glaucoma may disturb daily life because the frequency of admitting eye-drops is increased, it is less persistence or compliance, and results in the increase of local concentration of preservatives in the eye. The new fixed combination formulations for glaucoma have been developed to be safer, more effect and more compliable. This article reviews the comparative studies of therapeutic effects of anti-glaucoma fixed combination formulation and summarizes features of each formulation, and then prospects the new developing tendency of anti-glaucoma medication.
