PTCB Certified Pharmacy Technician (PTCE)MedicationsHard
A pharmacy technician is assisting a patient who reports muscle pain and weakness since starting a new medication for high cholesterol. The patient is taking 'simvastatin 40 mg daily'. Which of the following conditions is the MOST serious concern associated with these symptoms?
- ARhabdomyolysis
- BGout
- CTendinitis
- DOsteoporosis
Show answer & explanationAnswer & explanation
Correct answer: A. Rhabdomyolysis
Simvastatin is a statin, a class of drugs known to cause myopathy (muscle pain/weakness) and, in severe cases, rhabdomyolysis. Rhabdomyolysis is a rare but life-threatening condition involving rapid breakdown of muscle tissue, releasing harmful proteins into the blood that can lead to kidney failure. This requires immediate medical attention.
Why the other options are wrong
- B. Gout is a form of arthritis caused by uric acid buildup, unrelated to statin-induced muscle issues.
- C. Tendinitis is inflammation of a tendon and not typically associated with statin use.
- D. Osteoporosis is a bone-thinning disease and not a direct side effect of statins causing acute muscle pain.
Statin-Induced Rhabdomyolysis
Rhabdomyolysis is a rare but severe adverse effect of statin medications, characterized by rapid breakdown of damaged skeletal muscle. This releases myoglobin into the bloodstream, which can lead to acute kidney injury and other systemic complications.
- Symptoms include severe muscle pain, weakness, dark urine.
- Risk factors: high statin doses, drug interactions (e.g., grapefruit, fibrates), kidney impairment.
- Requires immediate medical attention and discontinuation of the statin.
Memory trick: Statin muscle pain: 'R' for 'Rhabdo' is the red flag.
