Any know off the top of their head, what caffeine is an inhibitor of?

 

[annawhisky]

aldosterone?

 

[DieselD]

Inhibits the reabsorption of Na? (so aldosterone?)


Edit: Wiki says it inhibits adenosine.

Inhibits reabsorption of Na+ ions, causing urination.

 

[vicinihil]

yes i think it inhibits reabsorption of Na+ ions, causing loss of water (urination)

not adh?

 

[studliness]

yep, caffeine is a diuretic

 

[limpkitty]

I think caffeine inhibits aldosterone and alcohol inhibits adh, one of the reasons you get more hungover from booze than coffee

 

[vicinihil]

damn if coffee gives you a hangover I don't know where I'd be by now

I feel the same🙂

sleep?

 

[niranjan162]

coffee is a diuretic so i think it would inhibit adh, also its effect on keeping you awake is thought to function by competively inhibiting adenosine

 

[supernareg]

it inhibits ADH, so collecting duct isnt as permeable to water, thus increasing water output.

ADH. Thats easy......

 

[UCDavisdude]

sleep?

lol

Got a good one, a patient comes in and is hyperglycemic, what abnormalities would you expect in relation to endocrinology

 

[freelove]

camp phosphodiesterase on the cellular level. it prolongs the effects of the catecholines (epinephrine and norepinephrine). I don't know what everyone else is talking about.

yep, caffeine is a diuretic

In one week in my med school's fluids / electrolytes / renal block, we had two different lecturers, one who said "We all know caffeine is a diuretic, so..." and another one said, "If you believe the hype that caffiene is a diuretic..."

Ahh, sweet nectar of bean.

 

[littlealex]

Yes caffeine is a diuretic, but that is not what the question is asking. What does caffeine inhibit, meaning why does caffeine make you more alert.

Freelove is right. Caffeine is a cAMP phosphodiesterase inhibitor, which causes a build up of cAMP in your cells, much like adrenaline would.

[amar21]

its ADH

alcohol and caffeine inhibit ADH.

ADH, so it makes you pee a lot. 🙂
