Risperidonesold under the trade name Risperdal among others, is an antipsychotic medication. Common side effects include movement problemssleepinesstrouble risperdal and movement disorder, constipation, and increased weight. Study of risperidone began in the late s and it was approved for sale in the United States in Risperidone is mainly used for the treatment of schizophreniabipolar disorderand irritability associated with autism. Risperidone is effective in treating the acute exacerbations of schizophrenia, risperdal and movement disorder.

Studies evaluating the utility of risperidone by mouth for maintenance therapy have reached varying conclusions. A systematic review concluded that there is strong evidence that risperidone is more effective than all first generation antipsychotics other than haloperidol, but that evidence directly supporting its superiority to placebo is equivocal, risperdal and movement disorder.

Data and information are scarce, poorly reported and probably biased in favour of risperidone, with about half of the included trials developed by drug companies. The article raises concerns regarding the serious side effects of risperidone, such as parkinsonism. Long-acting injectable formulations of antipsychotic drugs provide improved compliance with therapy and reduce relapse rates relative to oral formulations. Second generation antipsychotics, including risperidone, are effective in the treatment of manic symptoms in acute manic or mixed exacerbations of bipolar disorder.

Compared to placebo, risperidone treatment reduces certain problematic behaviors in autistic children, including aggression toward others, self-injury, temper tantrums, and rapid mood changes.

The evidence for its efficacy appears to be greater than that for alternative pharmacological treatments, risperdal and movement disorder.

Risperidone has shown promise in treating therapy resistant obsessive—compulsive disorderwhen serotonin reuptake inhibitors are not sufficient. Risperidone has not demonstrated a benefit in the treatment of eating disorders or personality disorders. While antipsychotic medications such as risperidone have a slight benefit in people with dementiathey have been linked to higher incidences of death and stroke. The British National Formulary recommends a gradual withdrawal when discontinuing antipsychotic treatment to avoid acute withdrawal syndrome or rapid relapse.

This question is unresolved, risperdal and movement disorder, and remains a highly controversial issue among professionals in the medical and mental health communities, as well the public. Older people with dementia-related psychosis are at a higher risk of death if they take risperidone compared to those who do not.

Most deaths are related to heart problems or infections. Risperidone has been classified as a "qualitatively atypical" antipsychotic agent with a relatively low risperdal and movement disorder of extrapyramidal side effects when given at low doses that has more pronounced serotonin antagonism than dopamine antagonism. Risperidone contains the functional groups of benzisoxazole and piperidine as part of its molecular structure.

Although not a butyrophenone, it was developed with the structures of benperidol and ketanserin as a basis. It has actions at several 5-HT serotonin receptor subtypes. These are 5-HT 2Clinked to weight gain, 5-HT 2Alinked to its antipsychotic action and relief of some of the extrapyramidal side effects experienced with the typical neuroleptics. It was recently found that D -amino acid oxidase vicoden and ibuprofen, the enzyme risperdal and movement disorder catalyses the breakdown of D -amino acids e.

D -alanine risperdal and movement disorder D -serine — the neurotransmitters is inhibited by risperidone. This drug is an antagonist of the D 1 D 1and D 5 as well as the D 2 family D 2D 3 and D 4 receptors, with fold selectivity for the D 2 family.

This drug has "tight binding" properties, which means it has a long half-life and like other antipsychotics, risperidone blocks the mesolimbic pathway, the prefrontal cortex limbic pathway, and the tuberoinfundibular pathway in the central nervous system.

Risperidone may induce extrapyramidal side effects, akathisia and tremorsassociated with diminished dopaminergic activity in the striatum. It can also cause sexual side effects, galactorrhoeainfertility, gynecomastia and, with chronic use reduced bone mineral density leading to breaksall of which are associated with increased prolactin secretion.

Its antagonistic actions at the 5-HT 2C receptor may account, in part, for its weight gain liability. This action accounts for its orthostatic hypotensive effects and perhaps some of the sedating effects of risperidone. Perhaps greater positive, negative, affective and cognitive symptom control.

Histamine H 1 receptors: This may also lead to drowsiness and weight gain. Though this medication possesses similar effects to other typical and atypical antipsychotics, it does not possess an affinity for the muscarinic acetylcholine receptors, risperdal and movement disorder. In many respects, this medication can be useful as an " acetylcholine release-promoter" similar to gastrointestinal drugs such as metoclopramide and cisapride.

Risperidone undergoes hepatic metabolism and renal excretion. Lower doses are recommended for patients with severe liver and kidney disease. Inthe FDA approved risperidone for risperdal and movement disorder treatment of irritability in autistic children and adolescents.

It is available under many brand names worldwide. Risperidone is available as a tablet, an oral solution, and an ampule, which is a depot injection.
