What is the best medication treatment for a patient with Attention Deficit Hyperactivity Disorder (ADHD) who has shown a positive response to Vyvanse (lisdexamfetamine) 30mg, but still experiences persistent symptoms of inattention and hyperactivity, and has a history of mood fluctuations and previous treatment with Prozac (fluoxetine)?

From the Guidelines

For a patient with ADHD who has shown a positive but incomplete response to Vyvanse 30mg and has a history of mood fluctuations and previous Prozac treatment, the best medication treatment approach would be to increase the Vyvanse dosage to 50mg daily. This recommendation is based on the principle of optimizing the current medication before considering additions or switches, especially since the patient has already demonstrated a partial response to Vyvanse without significant side effects 1. The dose increase should be implemented for at least 2-4 weeks to properly assess efficacy, as the full effects of stimulant medications can take several weeks to manifest.

Key Considerations

• The patient's history of mood fluctuations and previous treatment with Prozac (fluoxetine) is important, but given the positive response to Vyvanse, increasing the dose is a logical next step before reconsidering antidepressant therapy or adding other medications.
• Vyvanse can be safely titrated up to 70mg daily for adults, providing a range for potential dose adjustments based on efficacy and tolerability.
• If symptoms persist despite the increased dosage, adding a non-stimulant medication like guanfacine (1-4mg daily) could help address both attention and mood symptoms without the potential mood destabilization that can occur with stimulants 1.
• The effectiveness of Vyvanse stems from its conversion to dextroamphetamine, which increases dopamine and norepinephrine levels in the brain, improving attention and reducing hyperactivity, while the extended-release formulation provides daylong symptom control with once-daily dosing.

Monitoring and Adjustments

• Regular monitoring of the patient's response to the increased dose of Vyvanse, including assessment of ADHD symptoms, mood, and potential side effects, is crucial.
• Adjustments to the treatment plan may be necessary based on the patient's response, including further dose adjustments of Vyvanse or the addition of other medications like guanfacine for enhanced symptom control.
• Patient education on the importance of adherence to the prescribed medication regimen and open communication about any issues or concerns are vital for optimizing treatment outcomes.

From the FDA Drug Label

Lisdexamfetamine dimesylate capsules are a central nervous system (CNS) stimulant prescription medicine used for the treatment of: Attention Deficit Hyperactivity Disorder (ADHD) in adults and children 6 years of age and older. The exact mode of therapeutic action in ADHD and BED is not known.

The patient has already shown a positive response to Vyvanse (lisdexamfetamine) 30mg. Since the patient still experiences persistent symptoms of inattention and hyperactivity, the best medication treatment would be to continue or adjust the dose of Vyvanse (lisdexamfetamine) under the guidance of a healthcare provider, considering the patient's history and response to the medication.

• The patient's history of mood fluctuations and previous treatment with Prozac (fluoxetine) should be taken into account when adjusting the treatment plan.
• It is essential to monitor the patient's response to the medication and adjust the dose as needed to minimize side effects and maximize efficacy.
• The healthcare provider should also consider the potential for abuse, misuse, and addiction associated with lisdexamfetamine dimesylate capsules and monitor the patient accordingly 2, 2.

From the Research

Medication Treatment for ADHD

The patient has been diagnosed with Attention Deficit Hyperactivity Disorder (ADHD) and has shown a positive response to Vyvanse (lisdexamfetamine) 30mg. However, the patient still experiences persistent symptoms of inattention and hyperactivity.

• The patient's history of mood fluctuations and previous treatment with Prozac (fluoxetine) should be considered when determining the best medication treatment.
• Lisdexamfetamine, the active ingredient in Vyvanse, has been shown to be effective in treating ADHD symptoms in clinical studies 3, 4.
• The pharmacokinetics and pharmacodynamics of lisdexamfetamine have been compared to D-amphetamine, and the results suggest that lisdexamfetamine has a similar risk of oral abuse as D-amphetamine 5.

Considerations for Treatment

When considering the best medication treatment for this patient, the following factors should be taken into account:

• The patient's positive response to Vyvanse 30mg suggests that lisdexamfetamine may be an effective treatment option.
• The patient's history of mood fluctuations and previous treatment with Prozac (fluoxetine) may indicate a need for careful monitoring of mood symptoms while on medication.
• Lisdexamfetamine has been shown to be effective in treating binge eating disorder, which may be a comorbid condition in some patients with ADHD 6.
• The pharmacokinetics of lisdexamfetamine suggest a reduced potential for abuse, which may be an important consideration for patients with a history of substance abuse 7.

Potential Treatment Options

Based on the available evidence, potential treatment options for this patient may include:

• Continuing or increasing the dose of Vyvanse (lisdexamfetamine) to optimize treatment of ADHD symptoms.
• Monitoring the patient's mood symptoms closely while on medication and adjusting the treatment plan as needed.
• Considering the use of lisdexamfetamine for the treatment of comorbid conditions, such as binge eating disorder.
• Carefully evaluating the patient's risk of substance abuse and monitoring for signs of abuse or diversion while on medication.
