Study Notes
Hormones and Medications
-
Oxytocin
- Produced by the pituitary gland; stimulates uterine contractions.
- Administered during delivery and post-delivery to prevent hemorrhaging.
- Common side effects include rapid and painful contractions.
-
Finasteride
- Treats Benign Prostatic Hyperplasia (BPH).
- Alleviates symptoms like nocturia.
- Side effects may include sexual dysfunction and impaired fertility.
-
Sulfasalazine
- Used for ulcerative colitis.
- Associated with hepatotoxicity; caution in severe hepatic or renal impairment.
-
Orlistat
- Prescribed for obesity management.
-
Emergency Contraception
- Medication choice depends on the time elapsed since unprotected intercourse.
-
Methylnaltrexone
- Treats chronic constipation in patients on opioids, especially in advanced cancer.
-
Antacids
- Onset of action is 20-40 minutes; may be affected by concurrent medications.
- Provides temporary relief from heartburn by neutralizing stomach acid.
Disease Management and Treatment
-
DMARDs (Disease-Modifying Anti-Rheumatic Drugs)
- Slows disease progression and maintains joint function.
- Often combined with NSAIDs or steroids; risks include infection, bone marrow suppression, and hepatic fibrosis.
-
5 Alpha Reductase Inhibitors
- Inhibit testosterone conversion, promoting prostate shrinkage.
-
Vitamin A
- Safe in recommended pregnancy doses; excess can cause fetal malformation.
-
Alendronate
- A bisphosphonate for osteoporosis; may cause esophageal ulceration.
- Must be taken with a full glass of water and patient should remain upright for 30 minutes post-dose.
-
Magnesium Sulfate
- Used to delay preterm labor; has sedation and respiratory effects; overdose may result in decreased reflexes.
-
Bismuth Subsalicylate
- Binds to and eliminates gastrointestinal toxins.
Obstetrics and Gynecology
-
Terbutaline
- Given for preterm labor; black box warning for prolonged use during pregnancy.
-
Sildenafil
- Treats erectile dysfunction and pulmonary hypertension; may cause priapism and is contraindicated with nitrates.
-
Psyllium Mucilloid
- Must increase fluid intake; first-line treatment for constipation; takes days to be effective.
-
Folic Acid
- Deficiencies can arise from pregnancy, alcohol abuse, and malabsorption disorders.
-
H2 Receptor Antagonists
- Treats duodenal ulcers and prevents recurrence.
Contraception and Hormonal Therapy
-
Oral Contraceptives
- Effectiveness can be reduced by antibiotics, anticonvulsants, and antifungals; increased thromboembolic risk noted.
-
Testosterone
- Causes virilization from secondary exposure; used in breast cancer palliation to reduce tumor size.
-
Conjugated Estrogen
- Increases risk of blood clots, DVT, and is contraindicated in abnormal uterine bleeding.
-
Tamsulosin
- Also treats BPH and reduces nocturia.
-
Norethindrone
- Must be taken at the same time daily; side effect includes photosensitivity.
Gastrointestinal and Nutritional Considerations
-
Sucralfate
- Coats and heals gastric erosions; does not affect acid production.
-
Proton Pump Inhibitors (PPIs)
- Block gastric acid secretion; long-term use increases fracture risks; symptom relief may take days.
-
Medroxyprogesterone
- Given every 3 months via deep IM injection; risks include thrombotic events; avoid smoking.
-
Misoprostol
- Inhibits gastric acid secretion and promotes mucous production; primary use is to prevent peptic ulcers.
-
Ondansetron
- Administered before triggers; can lengthen QT interval, possibly causing dysrhythmias.
Total Parenteral Nutrition (TPN)
-
Requires central line with tubing changed every 24 hours; kept refrigerated and removed 30 minutes prior to administration; monitor blood sugar levels.
-
Risks associated with hormone replacement therapy include DVT, myocardial infarction, and dementia.
