A) Codeine - common in cough syrup but itโ€™s a weak agonist at mu and delta receptors, so thereโ€™s potential for substance abuse.
B) Dextromethorphan - a cough suppressant with low potential for abuse and does not cause constipation; antagonizes NMDA receptors (not mu kappa or delta receptors).
C & D) Hydromorphone & oxycodone -- potent opioids used to treat moderate to severe pain (I am assuming they work at mu receptors but itโ€™s not in FA so ๐Ÿคท๐Ÿปโ€โ™€๏ธ)

E) Tramadol - a weak opioid agonist used for neuropathic pain, acts by reuptake of NE and 5HT
