Formula Drugs

Prochlorperazine is a prescription used to treat nausea and vomiting. This used in a lower dose to treat the condition. This prescription may also be used for the treatment of anxiety and a certain psychiatric illness called schizophrenia.

Nausea and vomiting are not a disease but rather, these are symptoms of many different conditions such as:

  • Motion sickness
  • Food poisoning
  • Brain injury
  • Migraines
  • Appendicitis

Sometimes, it can also be symptoms of more serious diseases. Nausea and vomiting differ from each other. Nausea is an uneasiness of the stomach that often accompanies the urge to vomit. Vomiting is the forcible voluntary or involuntary emptying or throwing up of stomach contents through the mouth. Nausea and vomiting may happen in both children and adults.

Anxiety involves more than temporary worry or fear. That it does not go away and can get worse over time. The symptoms of this condition can interfere with daily activities such as school, job, and relationships. Experiencing occasional anxiety is a normal part of life. Symptoms may start during childhood or the teen years and continue into adulthood.

Schizophrenia affects how a person feels, thinks, and behaves. It can be a chronic or severe mental disorder. People with this illness may seem like they have lost touch with reality. Schizophrenia may result in some combination of delusions, hallucinations, and extremely disordered thinking.

Prochlorperazine is a type of drug known as a phenothiazine. This blocks dopamine receptors in the brain. Dopamine is a natural compound called a neurotransmitter that is involved in transmitting messages between brain cells. It is known to be involved in regulating mood and behavior. It also acts in an area of the brain that controls nausea and vomiting. This is a prescription approved by the Food and Drug Administration (FDA). This product comes as a tablet for oral use. Each tablet is available in the dosage forms of 5 mg and 10 mg with an active ingredient of Prochlorperazine.

How does Prochlorperazine work?

In nausea and vomiting, Prochlorperazine blocks dopamine receptors found in the chemoreceptor trigger zone (CTZ). Wherein, it stops it from sending the messages to the vomiting center that causes nausea and vomiting. Vomiting is controlled by an area of the brain called the vomiting center. The vomiting center is responsible for causing feelings of sickness and for the vomiting reflex. It activates when receives nerve messages from another area of the brain called CTZ and when it receives nerve messages from the gut.

In psychiatric illness, this medicine is sometimes described as a neuroleptic or a major tranquilizer. It has a calming effect on people suffering from anxiety. Schizophrenia is thought to be caused by the overactivity of dopamine in the brain. By blocking dopamine receptors, Prochlorperazine decreases the action of dopamine in the brain and it helps control psychotic symptoms.
