walbenazyna

Walbenazyna is a medication that belongs to a class of drugs known as phosphodiesterase 4 (PDE4) inhibitors. It is primarily used for the treatment of tardive dyskinesia, a neurological movement disorder characterized by involuntary, repetitive movements. These movements often affect the face, tongue, lips, and jaw, but can also involve the trunk and limbs. Tardive dyskinesia can be a side effect of long-term use of certain antipsychotic medications.

The mechanism of action of walbenazyna involves inhibiting the PDE4 enzyme. PDE4 is involved in the breakdown of cyclic adenosine monophosphate (cAMP), a signaling molecule within cells. By inhibiting PDE4, walbenazyna leads to increased levels of cAMP in certain brain regions, which is thought to help reduce the involuntary movements associated with tardive dyskinesia.

Walbenazyna is taken orally, typically once a day. The dosage is usually adjusted by a healthcare professional based on the individual's response and tolerance. Like all medications, walbenazyna can cause side effects. Common side effects may include drowsiness, dry mouth, constipation, and headache. More serious side effects are less common but can occur, and patients should discuss any concerns with their doctor. It is important to note that walbenazyna is a prescription medication and should only be used under the guidance of a qualified healthcare provider.
