摘要
Sodium bicarbonate alkalinizes the urine, which reduces the renal elimination of amphetamines. Dextroamphetamine exposure and duration of action can rise, increasing the risk of stimulant adverse effects such as tachycardia, hypertension, agitation and insomnia.
用白話說明這項交互作用的意義
Dextroamphetamine and Sodium bicarbonate 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.
Dextroamphetamine belongs to Central Nervous System; Sodium bicarbonate belongs to Gastrointestinal Tract.
為什麼會發生
Urinary alkalinization increases the non-ionized fraction of dextroamphetamine, enhancing tubular reabsorption and reducing renal clearance.
處置方式
Monitor heart rate, blood pressure and signs of stimulant excess when systemic alkalinizing agents are used regularly. Consider reducing the dextroamphetamine dose if symptoms of overstimulation appear.
