Quetiapine Fumarate

Quetiapine Fumarate is used to treat certain mental/mood disorder such as:

  • Bipolar disorder
  • Schizophrenia
  • Depression

Bipolar disorder is a mental health condition that causes extreme mood swings. It also includes emotional highs and lows. Episodes of mood swings may occur rarely or multiple times a year. While most people will experience some emotional symptoms between episodes, some may not experience any. Symptoms can cause unpredictable changes in mood and behavior resulting in significant distress and difficulty in life.

Schizophrenia usually appears in late adolescence or early adulthood. It is characterized by hallucinations, delusions, and other cognitive difficulties. This is a chronic brain disorder that requires lifelong treatment.  Schizophrenia involves a range of problems with thinking, behavior, and emotions. Signs and symptoms may vary but it also reflects an impaired ability to function.

Depression is classified as a mood disorder that may be described as a feeling of sadness or anger that interferes with a person’s everyday activities. People experience this condition in different ways. It may interfere with your daily work that results in lost time and lower productivity.  It can also influence relationships and some chronic health complications.

Quetiapine Fumarate is in the class of medications called antipsychotic drug which is an atypical type. This helps to restore the balance of certain natural substances in the brain. This medication can lessen hallucinations and may improve your concentration. It helps you improve your mood, appetite, energy level, and helps you feel less nervous. It will also help you think more clearly and positively about yourself and take a more active part in your everyday life. The U.S. Food and Drug Administration (FDA) has already approved this prescription. Quetiapine Fumarate is supplied as an extended-release tablet. Each tablet is available in the dosage forms of 50 mg, 150 mg, 200 mg, 300 mg, and 400 mg.  

How does Quetiapine Fumarate work?

Quetiapine Fumarate affects various neurotransmitters specifically serotonin (5HT) and dopamine. Neurotransmitters are chemicals stored in nerve cells. These are involved in transmitting messages between the nerve cells. Dopamine and serotonin are neurotransmitters known to be involved in regulating behavior, mood, and thinking. This medication works by blocking the receptors in the brain that dopamine acts on. This prevents the excessive activity of dopamine and helps control symptoms of certain psychotic illness. Quetiapine Fumarate improves symptoms such as disturbing thoughts, hallucinations, feeling depressed, and having a lack of emotion or becoming withdrawn. The psychotic illness appears to be caused by disturbances in the activity of neurotransmitters in the brain.
