Test 1 Drugs Flashcards
-Acetaminophen (Tylenol)
-COX Inhibitor
-Uses: Analgesic (mild to moderate pain), antipyretic (fever)
MOA: Inhibits prostaglandin synthesis via COX 2 inhibition
Ibuprofin
- NSAID/COX Inhibitor
- Uses: Analgesic (mild pain), antipyretic, dysmenorrhea
- MOA: Inhibition of COX1 an COX2
- Side effects: GI bleeding/ulcers due to COX 1 inhibition
Naproxen (Aleve)
- NSAID/COX Inhibitor
- Uses: Analgesic (mild pain), antipyretic
- MOA: Inhibition of COX 1 and COX2
- Preferred over ibuprofen due to longer half life (less frequent doses needed)
Ketorolac (Toradol)
- NSAID/COX Inhibitor
- Uses: Post-op pain
- Can have analgesic effects similar to morphine
- Must be administered IM
Indomethacin
- NSAID/COX Inhibitor
- Uses: Arthritis, gout, tendinitis
Aspirin
- NSAID/COX Inhibitor
- Uses: Antiplatelet (can protect against MI and stroke), analgesic, antipyretic
- MOA: Irreversible, non selective inhibition of COX1 and COX 2
- Side effects: Increased bleeding, Reye’s syndrome (children), GI distress
Celecoxib (celebrex)
- Second generation NSAID/selective COX 2 inhibitor
- Uses: Acute pain, arthritis
- MOA: Selective COX 2 inhibition
- Side effects: Dyspepsia, abdominal pain
- Only can be administered for 2-3 weeks
Tramadol
- Non-opiate narcotic
- Uses: Analgesic (mild to moderately severe)
- MOA: CNS weak opioid
Morphine Sulfate (MS-Contin)
- Opiate analgesic
- Uses: Severe acute or severe chronic pain (cancer, MI, dyspnea via pulmonary edema), preop
- MOA: Mu-receptor agonist
- Side effects: Sedation, respiratory depression, hypotension, pruritus (itchy skin)
Fentanyl (Sublimaze, Duragesic)
- Opiate analgesic
- Uses: Sever pain (periop, palliative care)
- MOA: Mu receptor agonist
- Side effects: Sedation, respiratory depression
Bethanechol (Urecholine)
- Muscarinic Agonist
- Parasympathomimetic/cholinergic
- Uses: Urinary retention via muscarinic activation of the bladder muscles
- Side effects: Hypotension, bradycardia, increased salivation, bronchoconstriction, sweating (more common when administered SC vs oral). CI for patients with hyperthyroidism-cardiac dysrhythmia
- Antidote: Atropine
Atropine
- Muscarinic Antagonist
- Anticholinergic/parasympatholytic
- MOA: Competitive blockage at muscarinic receptors
- Uses: Pre-anesthesia (decrease secretions), bradycardia, muscarinic agonist poisoning
- Side effects: Xerostomia (tooth decay), blurred vision and photophobia, urinary retention, tachycardia
- Antidote: Physostigmine
Oxybutynin (Ditropan) and Darifenicin (Enablex)
- Muscarinic agonist for OAB
- Cholinergic
- MOA: More selective for M3 muscarinic receptors, which are found on the bladder
Neostigmine (Prostigmin) and Physostigmine
…and Detrol but tha’ts less selective
- Cholinesterase Inhibitors
- Anticholinesterase
- MOA: Decreases activity of cholinesterase, thereby increasing levels of ACh
- Uses: Myasthenia gravis, atropine poisoning
- Side effects: Same as muscarinic agonist due to increased levels of ACh
Turbocurarine and vecuronium (competitive and nondepolarizing)
Succinylcholine (noncompetitive and depolarizing)
- Neuromuscular Blocking Agents
- MOA: Paralysis of muscles by blocking action of Nm receptor (depolarizing causes the muscles to contract but then they freeze)
- Uses: Paralysis for intubation, surgery, electroconvulsive therapy, and mechanical ventilation
- Charged molecules so must be given IV
- Side effects: Respiratory arrest and hypotension. For succinylcholine, malignant hyperthermia and hyperkalemia
Clonidine (Catapress)
- Indirect-acting anti-adrenergic agonist
- Alpha 2 agonist
- MOA: Activation of A2 receptors in the CNS decreases sympathetic outflow to vessels and to the heart via decreased release of transmitters
- Uses: Decreases HTN (also some severe pain and ADHD)
- Side effects: Drowsiness, xerostomia, rebound HTN if doses suddenly stop
Methyldopa
- Indirect-acting anti-adrenergic agonist
- Alpha 2 Agonist
- MOA: Activated withing neurons to become methyl-norepinephrine, activated A2 receptors
- Uses: HTN
Prazosin (minipress)
- Adrenergic antagonist
- Alpha blockade (drugs end in -sin)
- MOA: Blocks activation of alpha receptors
- Uses: HTN, reversal of A1 agonist toxicity, Raynaud’s disease
Tamsulosin (Flowmax)
- Adrenergic antagonist
- Alpha blockade
- Uses: BPH (used to help alleviate dysuria caused by BPH)
Narcan/Naloxone
- Opioid antagonist
- MOA: Blocks opioid effects
- Uses: Reversal of opioid effects
Propranolol
-Adrenergic antagonist
-First gen B blockage
-Non selective
Uses: Angina, HTN, MI, Heart failure
-Side effects B1: Bradycardia, reduced cardiac output, AV blockage
-Side effects B2: Bronchoconstriction, inhibition of glycogenolysis
Hydromorphone/Dilaudid
-Opioid agonist
-MOA: Mu agonist
Uses: Moderate to severe pain, heavily used in chronic cancer pain
-Less sedating than morphine
-Adverse effects: Sedation, respiratory depression, nausea and pruritis (less so than morphine due to less histamine)
Meperidine (Demerol)
- Opioid
- Mu and kappa agonist
- Used as an analgesic for patients with morphine allergy
- Side effects: Respiratory depression, sedation, hypotension
- Not popular anymore due to short half life
- Only used for 48 hours
Codein sulfate
- Opioid
- MOA: Mu agonist (week affinity)
