Flashcards
Duloxetine's action
Duloxetine's action
Duloxetine treats pain by affecting nerve signals (neuropathic pain), and is also an antidepressant targeting both serotonin and norepinephrine
Morphine's receptor action
Morphine's receptor action
Morphine primarily binds to Mu (μ) opioid receptors within the body, causing a powerful effect.
Naloxone's function
Naloxone's function
Naloxone is used to counter opioid overdoses by blocking opioid receptors, preventing the dangerous effects.

Study Notes
Drugs and Their Mechanisms
-
Depression:
- Duloxetine: Treats chronic neuropathic pain, dual-action antidepressant, active metabolite is desvenlafaxine.
- Selegiline: Transdermal patch, effective in patients unresponsive to SSRIs and TCAs.
- Venlafaxine: Dual-action antidepressant, targets serotonin and norepinephrine reuptake.
- Impramine: A tricyclic antidepressant.
-
Pain and Opioids:
- Morphine, Codeine, Heroin: Pure Mu agonists.
- Naloxone: Pure antagonist, reverses opioid overdose.
- Buprenorphine: Partial Mu agonist, limits respiratory depression and abuse potential.
- Suboxone: Buprenorphine + Naloxone.
- Pentazocine: Weak Mu antagonist + Kappa agonist, analgesic but dysphoric effects.
- Fentanyl: Mu antagonist
- Tramadol: Mixed agonist.
- Laudanum: Alcohol + Opioids
- Salvinorin A: Targets Kappa receptors.
- Kratom: Targets Delta receptors.
- Aspirin/NSAIDs: Decrease inflammation.
- Gabapentin/Pregabalin: Decrease nociceptor excitation.
- Opioids: Decrease neurotransmitter release by nociceptors.
- Antidepressants/Opioids: Activate anti-pain pathways.
- Opioids: Influence cognitive and emotional processing.
-
Sleep:
- Ramelteon: Melatonin agonist.
- Suvorexant: Orexin receptor antagonist.
- Caffeine: Adenosine receptor antagonist.
- Barbiturates and Alcohol: Suppress REM sleep.
- Z-drugs (Zaleplon, Zolpidem, Eszopiclone): Varying durations of action.
-
Psychedelics:
- Scopolamine: Anticholinergic, sedation and twilight anesthesia.
- Ololiuqui: Chemically similar to serotonin.
- Bufotenine: Chemically similar to serotonin, found in toad skin.
- Psilocybin: Chemically similar to serotonin, found in mushrooms.
- MDMA: Enhances communication and empathy.
- LSD: Visual, auditory, and space/time distortions.
- Mescaline: Chemically similar to dopamine and norepinephrine.
- Ketamine: Antiglutamatergic, NMDA receptor antagonist.
- PCP: Antiglutamatergic.
- Salvinorin A: Kappa opioid antagonist.
-
Weed (Marijuana):
- Rimonabant: Cannabinoid antagonist, suppresses appetite.
- Carboxy THC: Identifies THC in urine tests.
- Sativex: Analgesic, THC + CBD combination, suppresses pain in inflammatory conditions.
-
Drinking (Alcohol):
- Diazepam: Prevents withdrawal seizures.
- Disulfiram: Elongates unpleasant effects of alcohol, prevents relapse.
- Naltrexone: Prevents relapse.
- Lamotrigine: Anticonvulsant.
-
Addiction:
- Naloxone: Heroin antagonist.
- Methadone: Heroin agonist.
- Nicotine patches: Cigarette alternative.
- Varenicline (Chantix): Partial nicotine agonist.
- Disulfiram (Antabuse): Alcohol aversive treatment.
- Suboxone: Aversive treatment for opioids.
Key Drug Targets and Actions
- Opioids: Primarily target Mu receptors, and also Kappa/Delta receptors in some cases, either as agonists or antagonists. Actions include pain relief, but also potential for respiratory depression and euphoria.
