Seroquel (quetiapine) is a type of prescription medication called an antipsychotic drug. These medications often treat conditions that can cause psychosis or losing touch with reality, but they also help with different kinds of depression and anxiety—especially when first-line treatments aren’t enough.
There are two types of antipsychotic drugs. “Typical” antipsychotics refer to the first generation of these drugs, which were developed in the 1950s. “Atypical” antipsychotics, which were introduced in the 1990s, are considered second-generation drugs. They are just as effective as typical antipsychotics but are much less likely to cause complications such as movement and motor control problems.
Seroquel (quetiapine) is an atypical antipsychotic. It changes how certain chemicals (dopamine and serotonin) work in the brain.
Dopamine is a “chemical messenger” (neurotransmitter) that delivers instructions to nerve cells in the brain. It helps control mood, pleasure, motivation, memory, attention, and other functions. Serotonin is also a chemical messenger. It’s sometimes called the feel-good chemical because it helps regulate your mood and sense of well-being.
In people with depression or psychosis, dopamine and serotonin signals don’t work properly. Seroquel (quetiapine) works by blocking these abnormal signals.
Typical antipsychotics – list varies – – –There are two main classes of drugs called “typical” and “previously pre‑antipsychotics.” Typical antipsychotics change how certain chemicals (neurotransmitters) work in the brain. These abnormal signals are suppressed. They help people with psychosis or depression feel better, so they act as inhibitors or "statins” for other people.
Unlike pre‑antipsychotics, commonly used drugs called "previously pre‑antipsychotics” don’t work the way pre‑antipsychotics do. They prevent someone from feeling the effects the abnormal signals caused by the drug from working. These changes are made in the brain. Typical and pre‑preferors often have similar effects.
Preferors aren’t used for everything. Typical and preferotics often have side effects. Typical drugs that have preferotics include dexrazopide (exenatide), isavuform (loxapine), imipramine (norethisterone), quetiapine (Seroquel), and ziprasidone (ziprasidone). Preferotics for all other drugs include quetiapine, erythromycin, cimetidine, and others. Preferors for some are as follows:

Seroquel XR (quetiapine fumarate) is an atypical antipsychotic used to treat mental health conditions such as schizophrenia, bipolar disorder, and major depressive disorder.
When taken as prescribed, Seroquel XR works by blocking dopamine and serotonin receptors in the brain. This leads to a slowing of the movement of certain chemicals in the brain.
Seroquel XR comes in its usual strength of 50 mg once daily. It comes in a white, diamond-shaped tablet with a molecular weight of 5,600. It can be split into 3 doses: 300 mg (extended-release), 600 mg (extended-release), and 900 mg (release).
It should be noted that Seroquel XR is not indicated for the treatment of dementia. Seroquel XR is only recommended for short-term treatment of dementia-related conditions, including dementia-related psychosis. In some cases, it may be appropriate to increase the dosage of Seroquel XR or to change the medication regimen to reduce the risk of dementia-related conditions.
The most common side effects of Seroquel XR are nausea, diarrhea, and vomiting. More serious side effects include constipation, drowsiness, and loss of appetite.
Seroquel XR is not generally recommended for the treatment of dementia-related conditions. However, it is usually prescribed for the treatment of schizophrenia and bipolar mania.
Seroquel XR is metabolized in the liver. It can affect the amount of active drug in the body, and the level of this metabolite may be increased in patients with a history of seizures. The drug may also affect the effectiveness of some other medications. It is not recommended to stop taking Seroquel XR for any reason, such as to avoid the potential withdrawal of the drug, or to avoid the risk of addiction.
Seroquel XR may cause changes in blood glucose levels and liver enzymes.
This is not a complete list of all the drugs interactions that may occur.

In a clinical trial of the antipsychoticSeroquel (quetiapine)in elderly patients with schizophrenia, the rate of rehospitalization was significantly higher than placebo (17.5% vs. 6.4%). The rate of weight loss was significantly lower in the quetiapine group (7.2% vs. 4.4%, P<0.0001). The rate of weight loss was significantly higher in the quetiapine group compared with the placebo group (7.2% vs.

There were no significant differences in the weight loss between the groups in terms of age (P=0.631), total body water content (P=0.977), and water loss (P=0.3).
It is recommended to use the lowest dose of quetiapine for the shortest duration possible, and only in elderly patients with schizophrenia.
