Study Notes
Hormones and Contractions
- Oxytocin is produced by the pituitary gland and induces smooth muscle contractions in the uterus.
- Administered during delivery to regulate contractions and post-delivery to prevent hemorrhaging.
- Common side effect: rapid, painful contractions.
Medications for BPH
- Finasteride alleviates symptoms of benign prostatic hyperplasia (BPH), such as nocturia.
- Side effects may include sexual dysfunction and impaired infertility.
Ulcerative Colitis Treatment
- Sulfasalazine is used for ulcerative colitis but may cause hepatotoxicity.
- Caution is advised for patients with severe hepatic or renal impairment.
Obesity Management
- Orlistat is a medication prescribed for obesity management.
Emergency Contraception
- Emergency contraception effectiveness relies on the time elapsed since intercourse.
Chronic Constipation Treatment in Cancer
- Methylnaltrexone is used for managing chronic constipation in patients on opioids.
Antacids
- Antacids provide temporary relief from heartburn with an onset of action between 20-40 minutes.
- Absorption affected by other medications taken within two hours.
DMARDs
- Disease-modifying antirheumatic drugs (DMARDs) slow disease progression and maintain joint function.
- Often combined with NSAIDs or steroids; risks include infection and hepatic fibrosis.
Testosterone Conversion Inhibition
- 5 alpha reductase inhibitors prevent the conversion of testosterone, helping shrink an enlarged prostate.
Vitamin A and Pregnancy
- Recommended doses of vitamin A are safe during pregnancy, but excess can cause fetal malformations.
Bisphosphonates
- Alendronate, a bisphosphonate, may cause esophageal ulceration; precautions include taking with water and remaining upright for 30 minutes.
- Bone density tests assess treatment effectiveness.
Magnesium Sulfate
- Used to relax smooth muscles and delay preterm labor; overdose symptoms include confusion, muscle weakness, and sedation.
Bismuth Subsalicylate
- This medication binds to and eliminates gastrointestinal toxins.
Preterm Labor Treatment
- Terbutaline is utilized for preterm labor but has a black box warning against prolonged use during pregnancy.
Sildenafil for Erectile Dysfunction
- Sildenafil treats erectile dysfunction; it can cause priapism and is contraindicated with nitrates.
Stool Softeners
- Stool softeners increase water and fat absorption in stool.
Psyllium Mucilloid
- The first-line treatment for constipation; users should increase fluid intake.
Enteral Feedings
- Insufficient water consumption indicated by dry mucous membranes during enteral feedings.
Folic Acid Deficiency
- Pregnancy, alcohol abuse, and malabsorption disorders can lead to folic acid deficiency.
H2 Receptor Antagonists
- These are utilized for treating and preventing duodenal ulcers.
Oral Contraceptives
- Effectiveness of oral contraceptives may be reduced by antibiotics, anticonvulsants, and antifungal medications.
Testosterone and Breast Cancer
- Testosterone may cause velarization with secondary exposure and is used in palliative care to reduce tumor size.
Risks of Conjugated Estrogen
- Increased risk of blood clots, particularly for women over 35; contraindicated with abnormal uterine bleeding.
Tamulosin for BPH
- Tamulosin treats BPH and alleviates nocturia symptoms.
Norethindrone Administration
- Norethindrone should be taken consistently at the same time daily to maintain efficacy; side effects include photosensitivity.
Sucralfate
- Coats and heals gastric erosion without affecting acid production.
Selective Estrogen Receptor Modulators
- Contraindicated in patients with a history of venous thromboembolism.
Proton Pump Inhibitors (PPIs)
- Block hydrochloric acid secretion; long-term use is linked to increased fracture risk.
Medroxyprogesterone
- Long-acting contraceptive given intramuscularly every three months, with increased risks for thrombolytic events.
Misoprostol
- Prevents gastric acid secretion and stimulates mucous production, primarily for peptic ulcer prevention.
Ondansetron
- Administered prior to triggers to prevent nausea; can lengthen QT interval, leading to dysrhythmias.
Total Parenteral Nutrition (TPN)
- Must be delivered through a central line; monitor blood sugar levels and change tubing every 24 hours.
Hormone Replacement Therapy Risks
- Associated with increased risks for deep vein thrombosis (DVT), myocardial infarction (MI), and dementia.
