Alcohols
Agent that is metabolized to acetaldehyde by alcohol dehydrogenase and microsomal ethanol-oxidizing system (MEOS)
Ethanol
Agent with zero-order kinetics
Ethanol
Rate limiting step of alcohol metabolism
Aldehyde dehydrogenase
System that increases in activity with chronic ethanol exposure and may contribute to tolerance
MEOS
Enzyme that metabolizes acetaldehyde to acetate
Aldehyde dehydrogenase
Agents that inhibit aldehyde dehydrogenase (4)
Disulfiram, metronidazole, certain sulfonylureas and cephalosporins
Agent used in the treatment of alcoholism, if alcohol is consumed concurrently, acetaldehyde builds up and results in nausea, headache, flushing, and hypotension
Disulfiram
The most common neurologic abnormality in chronic alcoholics
Peripheral neuropathy (also excessive alcohol use is associated with HTN, anemia, and MI)
Agent that is teratogen and causes a fetal syndrome
Ethanol
Agent that is the antidote for methanol overdose (2)
Ethanol, fomepizole
Drug that inhibits alcohol dehydrogenase and is used in ethylene glycol exposure
Fomepizole
Anti seizure Drugs
Most frequent route of metabolism of seizure drugs
Hepatic enzymes
Mechanisms of action for Phenytoin, Carbamazepine, Lamotrigine
Sodium channel blockade
MOA for benzodiazepines and barbiturates
GABA-related targets
MOA for Ethosuximide
Calcium channels
MOA for Valproic acid at high doses
Affect calcium, potassium, and sodium channels
Drugs of choice for generalized tonic-clonic and partial seizures
Valproic acid and Phenytoin

Val-partial, Pheny-tonic
DOC for febrile seizures
Phenobarbital
Drugs of choice for absence seizures (2)
Ethosuximide and valproic acid
Drug of choice for myoclonic seizures
Valproic acid
Drugs of choice for status epilepticus (2)
IV diazepam for short term (acute) treatment; phenytoin for prolonged therapy
Drugs that can be used for infantile spasms
Corticosteroids
Anti-seizure drugs used also for bipolar affective disorder (BAD) (4)
Valproic acid, carbamazepine, phenytoin and gabapentin
Anti-seizure drug used also for Trigeminal neuralgia
Carbamazepine
Anti-seizure drug used also for pain of neuropathic orgin
Gabapentin
Anti-seizure agent that exhibits non-linear metabolism, highly protein bound, causes fetal hydantoin syndrome, and stimulates hepatic metabolism
Phenytoin
SE of phenytoin (4)
Gingival hyperplasia, nystagmus, diplopia and ataxia
Anti-seizure agent that induces formation of liver drug-metabolism enzymes, is teratogen and can cause craniofacial anomalies and spina bifida
Carbamazepine
Anti seizure agent that inhibits hepatic metabolism, is hepatotoxic and teratogen that can cause neural tube defects and gastrointestinal distress
Valproic acid
Laboratory value required to be monitored for patients on valproic acid
Serum ammonia and LFT's
SE for Lamotrigine
Stevens-Johnson syndrome
SE for Felbamate
Aplastic anemia and acute hepatic failure
Anti-seizure medication also used in the prevention of migraines
Valproic acid
Carbamazepine may cause
Agranulocytosis
Anti-seizure drugs used as alternative drugs for mood stabilization (4)
Carbamazepine, gabapentin, lamotrigine, and valproic acid
General Anesthetics
MOA of general anesthetics
Most are thought to act at GABA-A receptor - chloride channel
Inhaled anesthetic with a low blood/gas partition coefficient
Nitrous oxide
Inversely related to potency of anesthetics
Minimum alveolar anesthetic concentration (MAC)
Inhaled anesthetics metabolized by liver enzymes which has a major role in the toxicity of these agents (2)
Halothane and methoxyflurane
Most inhaled anesthetics SE
Decrease arterial blood pressure
Inhaled anesthetics are myocardial depressants (2)
Enflurane and halothane
Inhaled anesthetic causes peripheral vasodilation
Isoflurane
Inhaled anesthetic that may sensitize the myocardium to arrhythmogenic effects of catecholamines and has produced hepatitis
Halothane
Inhaled anesthetic, less likely to lower blood pressure than other agents, and has the smallest effect on respiration
Nitrous oxide
Fluoride released by metabolism of this inhaled anesthetic may cause renal insufficiency
Methoxyflurane
Prolonged exposure to this inhaled anesthetic may lead to megaloblastic anemia
Nitrous oxide
Pungent inhaled anesthetic which leads to high incidence of coughing and vasospasm
Desflurane

desflurane is desgusting
