4 Drug and Medication Information
4.1 Drug Indication

Xeplion is indicated for maintenance treatment of schizophrenia in adult patients stabilised with paliperidone or risperidone.

In selected adult patients with schizophrenia and previous responsiveness to oral paliperidone or risperidone, Xeplion may be used without prior stabilisation with oral treatment if psychotic symptoms are mild to moderate and a long-acting injectable treatment is needed.


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Antipsychotic Agents

Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus. (See all compounds classified as Antipsychotic Agents.)


Dopamine D2 Receptor Antagonists

Compounds and drugs that bind to and inhibit or block the activation of DOPAMINE D2 RECEPTORS. (See all compounds classified as Dopamine D2 Receptor Antagonists.)


Serotonin 5-HT2 Receptor Antagonists

Drugs that bind to but do not activate SEROTONIN 5-HT2 RECEPTORS, thereby blocking the actions of SEROTONIN or SEROTONIN 5-HT2 RECEPTOR AGONISTS. Included under this heading are antagonists for one or more specific 5-HT2 receptor subtypes. (See all compounds classified as Serotonin 5-HT2 Receptor Antagonists.)
