Tamoxifen is used in estrogen receptor-positive breast cancer. It acts as a:
Answer: Selective estrogen receptor modulator (SERM)
Tamoxifen is a SERM that antagonizes estrogen receptors in breast tissue while acting as a partial agonist in other tissues.
Which antiepileptic drug is preferred for absence seizures and works by blocking T-type calcium channels?
Answer: Ethosuximide
Ethosuximide selectively blocks T-type calcium channels in thalamic neurons, reducing the spike-wave discharges of absence seizures.
A patient on long-term corticosteroid therapy is at risk for osteoporosis. Which drug should be co-prescribed as prophylaxis?
Answer: Bisphosphonate plus vitamin D and calcium
Bisphosphonates (e.g., alendronate) with calcium and vitamin D are recommended to prevent glucocorticoid-induced osteoporosis.
Clozapine is reserved for treatment-resistant schizophrenia despite its efficacy because it carries a risk of:
Answer: Agranulocytosis
Clozapine can cause life-threatening agranulocytosis, requiring mandatory ANC monitoring with a REMS program.
Naloxone is administered to an unconscious patient suspected of opioid overdose. The expected immediate clinical effect is:
Answer: Reversal of respiratory depression
Naloxone competitively displaces opioids from mu-receptors, rapidly reversing respiratory depression.
Isotretinoin (13-cis-retinoic acid) is highly effective for severe acne but requires a REMS program primarily because it is:
Answer: Teratogenic
Isotretinoin is a potent teratogen that causes severe fetal malformations, requiring pregnancy prevention measures under iPLEDGE.
A patient with Type 2 diabetes is started on an SGLT2 inhibitor. Which additional clinical benefit beyond glucose lowering makes this drug class preferred in patients with established cardiovascular disease?
Answer: Reduced risk of heart failure hospitalization
SGLT2 inhibitors (e.g., empagliflozin) have demonstrated cardiovascular outcome benefits, including reduced heart failure hospitalization.
