Q

Simvastatin

A

Hypolipidemic: Competitive HMG-CoA reductase inhibitor (rate-limiting step of cholesterol synthesis) and induces high affinity LDL receptors–> reduces LDL levels

Toxicity = myositis and sometimes rhabdomyolysis (monitor creatine kinase) and hepatotoxicity (monitor liver enzymes)

Drugs that inhibit CYP enzymes will increase plasma concentrations of statins!!!

Q

Cholestyramine

A

Bile Acid Binding Resin: Binds BA in intestine and forms complex that’s excreted in feces.

  • More common in pots taking typical antipsychotics
  • Tx: switch patient to atypical drug (quetiapine or clozapine)

Neuroleptic Malignant Syndrome: rare but life threatening

  • caused by rapid blockade of post synaptic Da receptors
  • m rigidity, alterations in BP and HR, hyperthermia, muscle-type CK elevated
