What effect does Tafluprost have on aqueous outflow?

Tafluprost is a prostaglandin analog that is primarily used in the treatment of glaucoma and ocular hypertension. Its main mechanism of action is to increase the outflow of aqueous humor from the eye. This enhanced outflow occurs primarily through the uveoscleral pathway, which is one of the two main drainage pathways for aqueous humor. By facilitating the movement of aqueous fluid out of the eye, Tafluprost helps to lower intraocular pressure, which is crucial in managing conditions like glaucoma.

The other potential choices represent mechanisms that do not align with Tafluprost's pharmacologic effects. For instance, a decrease in outflow would exacerbate intraocular pressure instead of relieving it, while having no effect would fail to address the need for pressure reduction in glaucoma patients. Similarly, blocking outflow would be counterproductive, as it would lead to an increase in intraocular pressure rather than a decrease. Thus, the correct answer clearly illustrates the drug's beneficial role in promoting aqueous outflow.
