Sintesi

Amantadine has anticholinergic properties and may add to the antimuscarinic effects of trospium. This can cause dry mouth, constipation, urinary retention and confusion, particularly in older adults. Because both drugs are renally eliminated, impaired renal function can also raise exposure.

Cosa significa questa interazione in parole semplici

Amantadine and Trospium can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.

Amantadine belongs to Anti Virals; Trospium belongs to Genitourinary.

Livello di evidenza: Low

Perché avviene

Additive anticholinergic effects; both drugs are also renally cleared and may compete for tubular secretion.

Cosa fare

Monitor for anticholinergic effects and cognitive changes, and check renal function. Reduce doses if adverse effects appear.
