What is the duration of action for latanoprost?

• A. 2 hours
• B. 8 hours
• C. 12 hours
• D. 24 hours

Answer: (D)

Latanoprost is a prostaglandin analog commonly used in the treatment of glaucoma and ocular hypertension. Its primary action is to lower intraocular pressure by increasing the outflow of aqueous humor from the eye.

The duration of action for latanoprost is approximately 24 hours, making it a convenient once-daily treatment option for patients. This extended duration allows for stable intraocular pressure control and helps improve adherence to the medication regimen since patients only need to administer it once a day.

Other options representing shorter durations of action are not suitable, as they do not align with the pharmacokinetic properties of latanoprost. In summary, the 24-hour action reflects its effectiveness in maintaining intraocular pressure reduction over an entire day.
