Study Notes
Gout
- Gout results from uric acid crystals depositing in joints, leading to inflammation.
- Allopurinol is prescribed to decrease hyperuricemia, alleviating severe gout symptoms, with potential adverse effects including rash, Stevens-Johnson syndrome, and takes 1-3 weeks to effectively reduce uric acid levels.
Lithium, TCAs, Diazepam, Antipsychotics
- Lithium: A mood stabilizer for bipolar disorder, effectively reduces manic episodes, mimics sodium in the body, has a narrow therapeutic window, and may interact with various medications.
- TCAs (Tricyclic Antidepressants): Considered when first-line treatments fail; effects may take 4-8 weeks to fully manifest.
- Diazepam: A benzodiazepine with flumazenil as the designated reversal agent.
- Antipsychotics (e.g., Risperidone): Noted for fewer severe side effects compared to other options.
Ibuprofen, Ketorolac, Acetaminophen, Opioids, Naloxone
- Ibuprofen: Caution required in patients with kidney disease; can indicate GI bleeding on positive occult blood tests; classified as an NSAID, effective for mild to moderate pain, fever, and inflammation; increased risk of GI events, especially when combined with other NSAIDs like Ketorolac.
- Ketorolac: Marketed as Sprix/Toradol, similar cautions as ibuprofen regarding the use with other NSAIDs.
- Acetaminophen: Known as Tylenol, primarily reduces fever, serves as an alternative for patients unable to take ibuprofen or aspirin; potential adverse effects include hypotension, dry mouth, constipation, and sedation; recommended cautiously in patients with a history of gastric ulcers.
- Opioids: Prescribed for pain, chronic cough, and diarrhea; include morphine, oxycodone, fentanyl, and methadone; risk of dependency is significant with onset of effects within 30 minutes to 1 hour.
- Naloxone: An opioid receptor antagonist used for treating acute opioid overdoses, particularly effective for respiratory depression.
Antibiotics
Bacteriostatic vs. Bactericidal
- Bacteriostatic: Slows bacterial growth.
- Bactericidal: Kills bacteria outright.
List of Medications
- Vancomycin: An antibiotic effective against MRSA; side effects include low urine output and nephrotoxicity, requiring careful renal function monitoring.
- Sulfamethoxazole-Trimethoprim (Bactrim): Often prescribed for UTIs over a 3-day course; crosses the placental barrier, caution if used in pregnant patients.
- Gentamicin: Represents aminoglycosides; notable side effects include tinnitus and hepatotoxicity; carries a black box warning for potential neurotoxicity, particularly ototoxicity.
- Metronidazole: An antiprotozoan drug with contraindications against alcohol; it can elevate warfarin levels, resulting in increased bleeding risk, along with GI upset and a metallic taste.
- Macrolides: Inhibit protein synthesis and are bacteriostatic; typically administered in multiple forms for treating infections; specific for oral candidiasis.
- Nystatin: A superficial antifungal medication.
- Ciprofloxacin: A fluoroquinolone antibiotic associated with tendon rupture warnings; effective against anthrax, can be taken with or without food, and combats atypical bacterial infections like bronchitis and pneumonia.
