When teaching about timolol for glaucoma, what pharmacodynamics information should the nurse include?

The correct answer emphasizes that it may take a few weeks for timolol to achieve its full therapeutic effect in managing glaucoma. This is an important pharmacodynamic property because timolol is a non-selective beta-adrenergic antagonist that reduces intraocular pressure by decreasing the production of aqueous humor. While some initial effect may be noticeable, the full effect may take time as the body adjusts to the medication and consistent intraocular pressure reduction occurs.

This aspect is crucial for patient education, as individuals may become frustrated if they do not notice immediate improvements. Understanding the time frame for effectiveness can help ensure adherence to the treatment plan and manage expectations regarding the medication's impact on their condition.
