The capsules are taken once a day in the morning regardless of meals and improve the symptoms. Possible adverse effects include poor appetite, weight loss, diarrhea, dry mouth, nausea, stomach pain, vomiting, anxiety, dizziness, headache, irritability, and insomnia. The medicine can rarely cause serious side effects.

Products

Lisdexamphetamine (LDX) was approved in Switzerland in March 2014 in the form of capsules (Elvanse®). It has been available in the USA since 2007 (Vyvanse®).

In contrast to other ADHD drugs, the dosage form is not retarded. The sustained release is achieved with the conversion of the prodrug. Lisdexamphetamine is legally one of the narcotic drugs and is therefore more stringent on prescription.

Structure and properties

Lisdexamphetamine (C.15H25N3O, Mr = 263.8 g / mol) consists of the enantiomerically pure dexamphetamine, which is covalently bound to the amino acid lysine via a peptide bond. It is a prodrug that is continuously enzymatically hydrolyzed in the blood in the erythrocytes to the active ingredient D-amphetamine. Lysine does not contribute to the therapeutic effect. Lisdexamphetamine is available as lisdexamphetamine dimesilate, a white powder that is soluble in water.

Effects

Lisdexamfetamine (ATC N06BA12) is effective against the symptoms of ADHD. The mechanism of action is not fully understood. Dexamphetamine inhibits the reuptake of noradrenaline and dopamine into the presynaptic neuron and increases the concentration of monoamines in the synaptic cleft. In addition, it promotes the release of neurotransmitters from the presynapse.

Indications
  • As a second choice treatment for attention deficit / hyperactivity disorder ADHD.
  • Binge Eating (first registration in the USA in 2015)

unwanted effects
