Study Notes
Allopurinol: Overview
- Allopurinol is a xanthine oxidase inhibitor that reduces uric acid production, useful for treating gout, hypercalcemia, and renal calculi.
Mechanism of Action
- Inhibits xanthine oxidase enzyme, leading to decreased synthesis of uric acid in the body.
Contraindications
- Contraindicated in patients with hypersensitivity.
- Use with caution during acute gout attacks, renal impairment, and dehydration.
- Safety during pregnancy is not established; breastfeeding is only recommended if benefits outweigh risks.
- Extra caution is needed for older adults.
Monitoring and Lab Tests
- Regular monitoring of renal and hepatic function is essential.
- Required tests include assessment of allele genes and monitoring serum glucose levels.
- Allopurinol may elevate alkaline phosphatase, bilirubin, AST, and ALT levels, and may lead to decreased CBC levels.
Patient Education
- Increase fluid intake to enhance uric acid excretion and support kidney function.
- Female patients should report any pregnancies.
Yearly Assessments
- Patients should have an annual eye exam to detect visual changes that may occur due to long-term use of Allopurinol.
Patient Restrictions
- Avoid operating machinery while on Allopurinol, especially when consuming alcohol.
Pre and Post-Assessment
- Monitor hydration status; intake should be around 2500-3000 mL of fluids daily.
- Assess for any rash or signs of hypersensitivity.
- Observe for symptoms of gout, including swelling and pain.
Administration
- Allopurinol can be taken orally, possibly with milk to prevent gastric upset; tablets can be crushed with food if needed.
Side Effects and Adverse Reactions
- Possible side effects include hypotension, flushing, hypertension, bradycardia, and heart failure.
- Serious reactions could involve Stevens-Johnson syndrome, diarrhea, hepatitis, nausea, vomiting, renal failure, and bone marrow depression.
