Lisdexamfetamine is a prodrug of dextroamphetamine, which means that it is converted into dextroamphetamine in the body. It is a central nervous system (CNS) stimulant medication used to treat attention deficit hyperactivity disorder (ADHD). Lisdexamfetamine has a lower risk of abuse and dependence compared to other amphetamines, such as methamphetamine, dextroamphetamine, and dextroamphetamine and amphetamine combination products.

Lisdexamfetamine is a long-acting medication that is taken once daily, and it has a slower onset of action compared to other amphetamines. This slower onset of action may make it less attractive for abuse or misuse, as individuals seeking immediate effects may be less likely to use lisdexamfetamine.

However, it is important to note that all amphetamines have the potential for abuse and dependence, and they should only be used under the close supervision of a healthcare provider. Individuals taking amphetamines for ADHD should be closely monitored for signs of misuse, and the medication should be discontinued if misuse or abuse is suspected.

A: Ibuprofen does not typically interact with calcium citrate to decrease its effects. Instead, ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause gastrointestinal irritation and, with long-term use, may affect kidney function.

B: Hydrochlorothiazide is a diuretic that can lead to increased calcium levels in the blood. It does not decrease the effects of calcium citrate; rather, it could potentially cause hypercalcemia if used concurrently with calcium supplements.

C: Diltiazem is a calcium channel blocker used to treat hypertension and angina. While it affects calcium channels in the heart and blood vessels, it does not typically interact with calcium citrate supplements to decrease their effectiveness.

D: Prednisone is a corticosteroid that can decrease calcium absorption and increase calcium excretion, leading to lower bone density. Long-term use of prednisone can lead to osteoporosis, making it counterproductive when taken with calcium citrate for bone health.
