specific antidotes Flashcards
antidote for acetaminophen poisoning?
N-acetylcysteine (replenishes glutathione)
antidote for Salicylates
NaHCO3 (alkilinize the urine), dialyze
antidote for amphetimines
NH4Cl (acidify the urine bc amphetamines = basic)
antidote for Acetylcholinesterase inhibs/organophosphates
atropine (direct Ach inhib) + pralidoxime (regens AchE)
antidote for antimuscarinic, antichoinergic agents
physostigmine salicylate (anti-AChE and crosses BBB) + control hyperthermia
antidote for B-blockers
glucagon
antidote for Digitalis
LAMP Lidocaine Anti-dig Fab fragments Mg2+ K+
antidote for Iron
Deferoxamine, Deferasrox
antidote for Lead (4 options)
CaEDTA, dimercaprol, succimer, penicillamine
antidote for Mercury, arsenic, gold (2)
Dimercaprol (BAL), succimer

antidote for Heparin
protamine
antidote for Warfarin
FFP, vit k
antidote for tpa, streptokinase, urokinase
Aminocaproic acid
antidote for Theophylline
B-blocker
Affects of NE on BP and HR
NE = mainly alpha agonist
- Increased SVR (both diastolic and systolic) bc alpha ag —> increase BP
- Reflex bradycardia —> decrease BP
Affects of Isoproterenol on HR and BP
B affects > alpha affects:
- B2 vasodilation —> decrease SVR
- Reflex tach + B1 stim —> increase HR
Effects of Epi BEFORE and AFTER an ALPHA BLOCKER!
EPI = EVERY thing stim (alpha and beta)
1. BEFORE alpha blocker: increase alpha —> increase SVR!! —> net presser effect!
- AFTER alpha blocker —> only beta stim —> B2 = decrease SVR —-> reflex tach: decrease BP/increase HR
Effects of phenylephrine on BP before and after alpha blocker
Phenylephrine = alpha agonist
- BEFORE alpha blocker —> alpha ag —> presser —> Increase SVR
- After alpha blocker —> no effect at all
