Risperidone

Risperidone is a prescription used for the treatment of schizophrenia. It is a chronic and severe mental disorder that affects how a person feels, thinks, and behaves. People with this condition may seem like they have lost touch with reality. Although schizophrenia is not as common as other mental disorders, the symptoms may be very disabling. Some signs and symptoms include:

  • Delusions
  • Hallucinations
  • Movement disorders or agitated body movements)
  • Thought disorders (unusual dysfunctional ways of thinking)

This may also be used to treat bipolar disorder and irritability associated with autistic disorder.

Bipolar disorder is also called manic-depressive illness. It is a brain disorder that causes unusual shifts in mood, activity levels, and energy. It also causes the ability to carry out day-to-day tasks. There are several types of bipolar and related disorders. They may have included mania and depression. Symptoms can cause unpredictable changes in behaviors and mood. That it may result in significant distress and difficulty in life.

Autism is a developmental disorder that affects social and communication skills. Irritability is a symptom of autism that can complicate adjustment at home and other settings. It can also manifest itself in aggression, tantrums, and self-injurious behavior.

Risperidone is in the class of medications called atypical antipsychotics. This changes the activity of certain natural substances in the brain. It may help you think clearly and take part in everyday life. Risperidone is effective in relieving both positive and negative symptoms of schizophrenia, whereas the conventional antipsychotics are usually less effective against the negative symptoms.

This product is available as a sterile two-syringe mixing system; a liquid syringe prefilled with the delivery system. It is a colorless to yellow solution. Each dosage form contains Risperidone as an active ingredient. It is a white to off-white powder that is practically insoluble in water and soluble in methanol. In 1993, the Food and Drug Administration (FDA) has already approved this medication.

How does Risperidone work?

Risperidone works by interfering with communication among the nerves of the brain. Nerves communicate with each other by making and releasing chemicals called neurotransmitters. The neurotransmitters travel to other nearby nerves where they attach to receptors on the nerves. The attachment of the neurotransmitters either stimulates or inhibits the function of the nearby nerves. This drug blocks several of the receptors on nerves including serotonin type dopamine, type 2, and alpha 2 adrenergic receptors. It is believed that many psychotic illnesses are caused by abnormal communication among nerves in the brain. By altering communication through neurotransmitters, Risperidone can alter the psychotic state.

How to use Risperidone?

Risperidone is to be given by injection under the skin of the abdomen. It is given usually once a month or as directed by your doctor. The injection site will be cleaned with rubbing alcohol before each dose is injected. The site should be changed each time to lessen injury under the skin.
