Summary

On this episode, I discuss timolol pharmacology, adverse effects, drug interactions, and much more.



Timolol is a non-selective beta-blocker so it blocks both beta-1 and beta-2 receptors.



Since timolol blocks beta-2 receptors, it can blunt the effect of respiratory medications that have beta-agonist action.



Beta-blockers are notorious for causing bradycardia and pulse is an important monitoring parameter for timolol.

used in the oral dosage form, but I certainly will talk about that a great deal. But I also

1:03.6

wanted to mention there is an eyedrop formulation or maybe a couple formulations as well.

1:09.9

So as you could imagine uses for this medication,

1:15.7

so if it's a beta blocker taking orally for systemic circulation,

1:38.3

There's generally other agents that are preferred, but in rare cases, maybe you will see this. So beta blockers,

just a quick reminder, they block beta receptors, adrenergic beta receptors. And ultimately,

this can lead to a reduction in blood pressure and sympathetic outflow,
