Resumo
Ascorbic acid in large doses can acidify the urine, which increases renal excretion of amphetamines and may reduce their effect. The effect is most relevant with high-dose vitamin C.
O que esta interação significa em palavras simples
Dextroamphetamine transdermal and Vitamin c 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.
Por que acontece
Urinary acidification ionizes amphetamine and reduces renal tubular reabsorption, increasing clearance.
