Q1. Correct answer: D. Lorcaserin (Belviq).
Lorcaserin may cause valvulopathy, attention, or memory disturbance. This patient has normal ECHO and does not work with heavy machinery. Given his other history, this may be the best choice for him. Naltrexone/bupropion extended release is contraindicated in patients with seizure disorder, chronic opioid use, anorexia nervosa, bulimia, and abrupt discontinuation of alcohol, benzodiazepines, barbiturates, or antiepileptic drugs because bupropion lowers the seizure threshold. Liraglutide is contraindicated with personal or family history of medullary thyroid carcinoma or MENII. In addition, GLP1 receptor agonists can increase the risk of pancreatitis in patients with a history of pancreatitis. Phentermine/topiramate can increase the risk of nephrolithiasis. All of these medications are contraindicated in pregnancy and in patients with hypersensitivity to the drug and drug class.
