Xalatan 0.005 % is a prescription eye drop formulated as a prostaglandin analog for ophthalmic use. It is prescribed to reduce intraocular pressure in patients with open-angle glaucoma or ocular hypertension. The active ingredient latanoprost mimics endogenous prostaglandin f2a and activates specific receptor subtypes. Activation stimulates the uveoscleral outflow pathway enhancing the drainage of aqueous humor. Increased outflow leads to a measurable decrease in intraocular pressure over several hours. The drug is applied once daily in the evening allowing sustained pharmacological effect throughout the night. Systemic absorption is minimal resulting in limited exposure outside ocular tissues. This localized action provides therapeutic benefit without requiring systemic medications.

Xalatan 0.005 % is a prostaglandin analog medication formulated as an ocular solution for lowering intraocular pressure. Its therapeutic role is to reduce intraocular pressure in patients with open-angle glaucoma or ocular hypertension. The drug works by mimicking the action of endogenous prostaglandin f2 alpha, which binds to receptors in the trabecular meshwork. Activation of these receptors enhances the outflow of aqueous humor through the uveoscleral pathway. By increasing drainage, Xalatan 0.005 % lowers intraocular pressure, thereby decreasing the risk of optic nerve damage. The medication's effect is sustained over time, requiring once-daily administration to maintain consistent pressure control.

Xalatan eye drops can cause mild eye irritation or burning sensation. Some users may experience itching or redness of the eyelid. Blurred vision may occur temporarily after application. Rarely, changes in eye color or increased pigmentation can develop. Sensitivity to light or a feeling of dryness may be observed. In some cases, increased intraocular pressure can happen even with proper use. These effects are generally infrequent and often resolve as treatment continues.

Xalatan 0.005 % may cause eye irritation or itching in some patients. It can lead to gradual pigmentation of the iris but this effect is usually reversible. Some users may experience blurred vision after application. Rarely it can cause ocular inflammation or allergic reactions. Elevated intraocular pressure can occur if the medication is not used as prescribed. Long term use may result in changes to eyelash growth around the treated eye.
