Study Notes
Monitoring and Side Effects of Propylthiouracil (PTU)
- Patients should be monitored for signs of infection including fever and sore throat.
- Regular blood cell counts are essential during PTU therapy.
- Common side effects include skin rash, pruritus, urticaria, joint and muscle pain, nausea, vomiting, and gastrointestinal upset.
Cautions for PTU Use
- Use cautiously in patients with mild to moderate liver dysfunction due to the risk of hepatotoxicity.
- Preferred in the first trimester of pregnancy over methimazole due to lower risk of congenital malformations; risks versus benefits should be carefully considered.
- Excreted in breast milk, requiring caution in breastfeeding women.
Drug Interactions with PTU
- May potentiate effects of anticoagulants, increasing bleeding risk; close monitoring of coagulation parameters needed.
- Concurrent use with theophylline can increase theophylline levels, requiring dose adjustments.
- Can interfere with warfarin metabolism, leading to fluctuations in INR.
Adrenal Hormones Overview
- Understand normal anatomy, physiology, and functions of adrenal glands, including hormones released.
- Compare adrenal medulla hormones (e.g., catecholamines) with those of the adrenal cortex (e.g., cortisol, aldosterone).
- Glucocorticoids and mineralocorticoids differ in properties, roles, diseases affecting them, and pharmacotherapy applications.
Key Anterior and Posterior Pituitary Drugs
- Important anterior pituitary drugs include cosyntropin, somatropin, and octreotide.
- Posterior pituitary drugs are vasopressin and desmopressin, with a focus on somatropin, octreotide, and vasopressin for assessments.
Patient Education Essentials
- Avoid use in case of known allergies or hypersensitivity to the drug or its components.
- Read and follow instructions precisely as prescribed and keep track of medication doses for timely refills.
- Contact healthcare provider if symptoms do not improve or worsen, or if concerning side effects occur.
- Inform healthcare providers about other medications, including OTC drugs and supplements, to prevent interactions.
- Educate patients on potential side effects and proper administration for optimal treatment outcomes.
- Patients with comorbidities need careful monitoring during any therapy.
Corticosteroid Considerations (Prednisolone)
- Adverse effects may include gastritis, peptic ulcers, gastrointestinal bleeding, mood swings, agitation, and insomnia.
- Caution advised in patients with diabetes, cardiovascular diseases, existing infections, glaucoma, and those with hepatic impairment.
Drug Interactions with Prednisolone
- Can potentiate effects of anticoagulants, raising bleeding risk; increases gastrointestinal bleeding and ulceration risk when used with NSAIDs.
- May elevate blood levels of cyclosporine and reduce vaccine effectiveness; live vaccines should be avoided.
Review Drugs for Quiz Preparation
- Focus on drug profiles: octreotide, somatropin, vasopressin, levothyroxine, propylthiouracil, fludrocortisone, methylprednisolone, prednisone, acarbose, glipizide, liraglutide, metformin, pioglitazone, repaglinide, sitagliptin.
