What treatment method is indicated for patients experiencing an overdose of amphetamines?

In the case of amphetamine overdose, urinary acidification plays a crucial role in treatment. Amphetamines are basic compounds that can be more effectively excreted when urine is made more acidic. When the urine's pH is lowered, this enhances the ionization of the drug, which decreases its reabsorption in the renal tubules and facilitates its elimination from the body. This pharmacological principle is essential in managing toxic levels of amphetamines, helping to accelerate their removal from the system.

While options such as gastric lavage, oral activated charcoal, and intravenous fluids may be considered in various contexts of overdose treatment, they are not the primary or most effective methods for addressing amphetamine overdoses specifically. Gastric lavage may be indicated shortly after ingestion in some cases, but it is not routinely recommended due to risks and limited benefit. Oral activated charcoal can be used to bind unabsorbed drug, but its effectiveness decreases as time passes after ingestion, particularly in a stimulant overdose context where the effects can be prolonged. Intravenous fluids may provide support for dehydration or other symptoms but do not directly address the pharmacokinetics of amphetamines in the way that urinary acidification does. Thus, urinary acidification is the most appropriate treatment strategy for
