Medication-induced hypophosphatemia: a review.

Area of Science:

• Internal Medicine
• Clinical Pharmacology
• Biochemistry

Background:

• Hypophosphatemia (serum phosphorus <2.5 mg/dl) is uncommon in the general population but prevalent in hospitalized patients.
• Drug therapy, particularly with diuretics and bisphosphonates, is a frequent cause of acquired hypophosphatemia.
• Clinical presentation ranges from mild to severe, potentially life-threatening complications.

Purpose of the Study:

• To review the pathophysiological mechanisms of drug-induced hypophosphatemia.
• To identify risk factors associated with medications causing hypophosphatemia.
• To provide insights for prevention and intervention strategies.

Main Methods:

• Literature review of studies on drug-induced hypophosphatemia.
• Analysis of pathophysiological pathways linking medications to low serum phosphorus.
• Synthesis of clinical data on manifestations and risk factors.

Main Results:

• Certain common medications significantly increase the risk of developing hypophosphatemia.
• Understanding the specific drug mechanisms is crucial for diagnosis.
• Early identification of risk factors can guide preventative measures.

Conclusions:

• Drug-induced hypophosphatemia requires careful medical history, focusing on medication use.
• Knowledge of mechanisms and risk factors aids in managing and preventing this condition.
• Effective intervention strategies can mitigate the severity of drug-related hypophosphatemia.
