QUESTION
Betal blockersl pharmacodynamics
Answer:
-HRl andl strokel volume
-occupyl betal receptorl sitesl andl competitievlyl preventingl occupancyl ofl thesel sitedl byl
catacholeaminesl andl otherl betal agonists
cardsl effect:l blockagel ofl betal 1l receptorsl decreasel heartl rate,l decreasel contractility,l
conductionl velocityl andl slowsl conductionl atl thel AVl junctionl
renall effects:l reducesl releasel ofl reninl (Betal 1l receptors)
respiratory:l blocksl Betal 2l receptors,l resultingl inl bronchoconstrictionl (l usel cautionl inl
reactivel airwayl disorders)
ocular:l decreasel intraocularl pressure
