Amphetamine mixed salts (medication)

Amphetamine mixed salts (AMS) is a pharmacological preparation containing a mixture of amphetamine salts, commonly used in the treatment of Attention Deficit Hyperactivity Disorder (ADHD) and narcolepsy. This medication is known under various brand names, including Adderall®, a widely recognized formulation. The mixture typically comprises equal parts of four different amphetamine salts: dextroamphetamine sulfate, amphetamine sulfate, dextroamphetamine saccharate, and amphetamine aspartate monohydrate. This combination is designed to provide a balanced and sustained stimulant effect to improve concentration, focus, and control impulsivity and hyperactivity in individuals with ADHD.

Composition and Mechanism of Action

Amphetamine mixed salts work by increasing the levels of neurotransmitters, dopamine and norepinephrine, in the brain. These neurotransmitters play essential roles in attention and behavior regulation. By enhancing their action, AMS can effectively reduce the core symptoms of ADHD. The unique composition of AMS allows for a gradual release of the active ingredients, ensuring a prolonged effect that can last throughout the day, thereby improving the symptom management for individuals with ADHD.

Indications

The primary indication for amphetamine mixed salts is the treatment of Attention Deficit Hyperactivity Disorder (ADHD) in both children and adults. It is also approved for the treatment of narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks. AMS may be considered in other off-label uses as determined by a healthcare provider, based on its stimulant properties.

Dosage and Administration

The dosage of amphetamine mixed salts is highly individualized, based on the patient's medical condition, response to treatment, and other factors. It is typically administered orally, once or twice daily, depending on the specific formulation. Extended-release formulations are available, which allow for once-daily dosing. It is crucial for patients to follow their healthcare provider's instructions closely when taking AMS to minimize potential side effects and achieve the best possible outcome.

Side Effects

Common side effects of amphetamine mixed salts include, but are not limited to, decreased appetite, weight loss, dry mouth, insomnia, anxiety, and increased heart rate. More severe side effects may occur and should be reported to a healthcare provider immediately. These can include signs of heart problems, psychiatric symptoms such as new or worsening behavior and thought problems, or signs of circulation problems.

Contraindications and Precautions

Amphetamine mixed salts are contraindicated in individuals with a known hypersensitivity to amphetamines or any component of the formulation. It is also contraindicated in patients with a history of drug abuse, glaucoma, severe anxiety or agitation, and certain cardiovascular conditions. Due to the potential for abuse and dependence, AMS should be prescribed and used with caution, following guidelines for controlled substances.

Interactions

AMS can interact with several other medications, including monoamine oxidase inhibitors (MAOIs), certain antidepressants, and blood pressure medications. These interactions can lead to increased risk of adverse effects or reduced efficacy of treatment. Patients should inform their healthcare provider of all medications they are taking to avoid potential interactions.

Conclusion

Amphetamine mixed salts are an effective treatment option for ADHD and narcolepsy, offering symptom relief and improved quality of life for many individuals. However, due to the potential for side effects, abuse, and dependence, it is important for patients to use this medication under the close supervision of a healthcare provider.
