Comparing two prostate medications' effects on eye structures
Treatments studied
Part of Eyes & vision, Kidney & urinary clinical trials.
This study compares two medications for an enlarged prostate to see how they affect the size of the pupil and the thickness of a layer in the back of the eye. It may help you understand potential eye-related side effects of these treatments.

This study compares two prostate medications (tamsulosin and silodosin) to see how they might affect the iris — the colored part of your eye. It may help doctors choose the best option for men who also have concerns about their eyes.
This trial compares two medications, silodosin and tamsulosin, to see which one works better for men with frequent or difficult urination caused by an enlarged prostate. All participants will try both medicines at different times to find the best option.
This study tests whether taking tadalafil (at 2.5 mg or 5 mg) along with tamsulosin is better for treating urinary symptoms caused by an enlarged prostate than taking tamsulosin alone. It aims to find the best dose combination to improve your quality of life.
This trial tests a new, once-daily tablet (H077) compared to the standard medicine silodosin for treating symptoms of an enlarged prostate. It aims to see if the new medicine works as well and is safe.
This trial tests how a medication called silodosin (8 mg once daily) affects symptoms and ejaculatory function in men with an enlarged prostate causing urinary problems. It aims to understand both the benefits and side effects of this treatment.
This trial tests whether increasing your prostate medication (tamsulosin) or switching to a different medication (silodosin) helps you urinate normally again after a sudden blockage caused by an enlarged prostate. The goal is to help you avoid long-term catheter use.
