Drug Type		Small molecule				Small molecule
Therapeutic Class		Cns Stimulants				Minerals And Electrolytes
Structure

Mechanism of Benzphetamine-Potassium citrate Interaction (Severity Level: Moderate)
Altered urine pH Click to Show/Hide Mechanism Graph
Drug Name		Benzphetamine				Potassium citrate
Mechanism		Urine pH sensitive				Urine alkalinizer
Key Mechanism Factor 1
		Factor Name		Urine pH
		Factor Description		The normal range of urine pH is between 4.5 and 8, depending mainly on the hydrogen ion concentration. Changes in urine pH may significantly affect drug reabsorption and excretion.
Mechanism Description		Altered elimination of Benzphetamine caused by Potassium citrate mediated altered urine pH

Recommended Action
Management		Urinary alkalinizers should generally not be used with amphetamines, particularly in an amphetamine overdose situation.
