Does risperidone affect metabolism?
Does risperidone affect metabolism?
Therefore, our findings offer evidence that risperidone treatment alters the composition of the microbiome which suppresses resting metabolic rate and leads to weight gain.
How long does it take to metabolize risperidone?
In poor metabolizers the half-life of risperidone was about 19 hours compared with about 3 hours in extensive metabolizers.
What enzyme metabolizes risperidone?
Risperidone is an active compound that is mainly metabolized in the liver by cytochrome P450 enzymes such as CYP2D6. An active metabolite in the main hydroxylation pathway is 9-hydroxyrisperidone.

How is paliperidone metabolized?
Paliperidone is metabolized to some extent by the cytochrome P450 system (CYP 2D6 and 3A4), but is an uncommon cause of significant drug-drug interactions with agents that inhibit or induce these microsomal enzymes.
How do I reduce risperidone?
If you are considering stopping taking antipsychotics, it is worth thinking about the following:
- It is safest to come off slowly and gradually. You should do this by reducing your daily dose over a period of weeks or months.

What is the CYP2D6 * 10 allele?
CYP2D6 is a clinically important enzyme that metabolizes numerous therapeutic drugs. 16 Among the alleles of CYP2D6, CYP2D6*10 (C100T) is the most common allele in the Asian population, with a frequency of between 30% and 69.2%, where 13%–49% of the aforementioned population are homozygous for this allele.

Does Risperdal Slow Your Metabolism?
Slow metabolism: It’s no secret that atypical antipsychotics can slow the metabolism, and Risperdal is no exception. This means that even if you are able to maintain the same level of physical activity, are eating the same portion sizes, and same foods as you were pre-treatment, you’re going to gain weight.
How fast does Risperdal start working?
