Drug interactions
prednisolone + salbutamol
For healthcare professionals — reference only. This page is a brief summary, not medical advice and not a substitute for official labeling or clinical judgement. Always verify before prescribing or dispensing.
Overview
Combined use can potentiate hypokalemia from beta-2 agonists, increasing risk of arrhythmias; risk rises with high-dose/systemic steroid use or severe asthma.
Mechanism of action
Beta-2 agonists drive intracellular K+ shift; glucocorticoids increase renal potassium loss, producing additive hypokalemia.
Clinical management
Use lowest effective doses; monitor serum potassium (baseline/periodically) and consider ECG in high-risk patients; correct electrolytes; use caution with other K+-lowering drugs (diuretics, xanthines).
