Study Notes
Hormones and Contractions
- Oxytocin: Produced by the pituitary gland; stimulates uterine smooth muscle contractions during delivery; aids in regulating contractions and preventing post-delivery hemorrhaging; common side effect includes rapid and painful contractions.
Medications for Specific Conditions
- Finasteride: Treats benign prostatic hyperplasia (BPH) by decreasing symptoms like nocturia; side effects include sexual dysfunction and impaired fertility.
- Sulfasalazine: Prescribed for ulcerative colitis; carry risks of hepatotoxicity; use cautiously in patients with severe liver or kidney impairments.
- Orlistat: A medication used to manage obesity by inhibiting fat absorption.
- Emergency Contraception: Decision is based on the timing since intercourse occurred; works to prevent pregnancy post-coitus.
- Methylnaltrexone: Designed for chronic constipation relief in patients with advanced cancer on opioids.
Antacids and Gastrointestinal Medications
- Antacids: Onset of action between 20-40 minutes; neutralizes stomach acid, providing temporary relief from heartburn; absorption may be impaired if taken with other medications.
- DMARDs: Help slow disease progression in chronic conditions; often combined with NSAIDs or steroids to manage inflammation and pain; risk of infections, bone marrow suppression, and hepatic fibrosis increases.
- 5-alpha Reductase Inhibitors: Prevent conversion of testosterone, promoting prostate shrinkage; effective in treating BPH.
- Alendronate: A bisphosphonate that may cause esophageal irritation or ulceration; requires full glass of water intake and upright posture post-consumption.
- Magnesium Sulfate: Used to relax smooth muscle and delay preterm labor; monitor for overdose symptoms such as confusion and muscle weakness; avoid alcohol as it can enhance sedative effects.
Vitamins and Nutritional Considerations
- Vitamin A: Necessary for vision; safe in recommended doses during pregnancy but excess can lead to fetal malformations.
- Folic Acid: Deficiency can occur due to pregnancy, alcohol abuse, or malabsorption disorders; supplementation is vital.
Hormonal Therapies and Contraceptives
- Conjugated Estrogen: Commonly used for menopausal symptoms; increases risks of blood clots and other side effects, especially in women over 35; contraindicated in abnormal uterine bleeding.
- Norethindrone: Taken consistently daily; patients should be aware of photosensitivity; St. John's Wort can interfere with efficacy leading to breakthrough bleeding.
- Medroxyprogesterone: Long-term contraceptive administered via deep IM every three months; smoking and use of St. John's Wort can increase thrombolytic event risks.
Treatment of Ulcers and Other Conditions
- H2 Receptor Antagonists: Useful in treating duodenal ulcers and preventing recurrence; effectiveness may decrease when taken alongside antacids.
- Sucralfate: Coats and heals gastric erosions without impacting acid production; beneficial for peptic ulcer disease.
- Zofran (Ondansetron): Administered before triggers to prevent nausea; potential to lengthen QT interval and cause dysrhythmias.
IV Fluids and Electrolytes
- TPN (Total Parenteral Nutrition): Requires central line administration; monitored for blood glucose levels; remove from refrigeration 30 minutes before use.
- Crystalloids: Contain electrolytes; mimic extracellular fluid; effective for hypovolemic shock.
- Colloids: Plasma protein solutions that maintain fluid within blood vessels; rapid administration can lead to fluid overload.
Other Important Points
- Priapism: A serious condition associated with medications for erectile dysfunction; contraindicated with nitrates due to hypotension.
- Psyllium Mucilloid: First-line agent for constipation; takes several days to effect; increases water absorption in stool; essential to increase fluid intake.
- Bismuth Subsalicylate: Used for diarrhea as it binds and absorbs toxins.
- Terbutaline: Tocolytic medication for preterm labor; has a black box warning against use for more than 48-72 hours due to fetal risks.
