Sintesi

Both granisetron and artemether can prolong the QT interval. Taken together, the additive effect may raise the risk of torsades de pointes and other serious ventricular arrhythmias, especially with electrolyte disturbances or underlying heart disease.

Cosa significa questa interazione in parole semplici

Artemether and Granisetron can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Livello di evidenza: Moderate

Perché avviene

Additive pharmacodynamic QT prolongation through cardiac repolarization (hERG potassium channel) effects.

Cosa fare

Use an alternative antiemetic such as one with less QT effect if possible. If co-use is needed, check baseline and follow-up ECG and correct potassium and magnesium.

Cosa chiedere al farmacista
