Seroquel Metabolism in the Liver
Seroquel metabolism primarily occurs in the liver, where it undergoes extensive hepatic metabolism. The active ingredient, quetiapine, is extensively metabolized by the liver enzyme CYP3A4, with a minor contribution from CYP2D6.
- CYP3A4 is responsible for the formation of N-desalkylquetiapine (NOR-quetiapine), the active metabolite that also possesses sedative and antipsychotic properties.
- CYP3A4 also plays a role in the formation of other metabolites like 7-hydroxyquetiapine, which is pharmacologically inactive.
- The contribution of CYP2D6 to Seroquel metabolism is minimal, with only a small portion of the drug being converted to its active metabolite, norquetiapine, through this enzyme.
The metabolism of Seroquel is also affected by other factors, including age, gender, genetics, and drug interactions.
Older adults, for example, metabolize Seroquel more slowly than younger individuals due to age-related decline in liver function and reduced enzymatic activity. Women are also known to metabolize Seroquel more slowly than men, which may explain why they are at a higher risk of experiencing adverse effects from the drug.
Drug interactions also affect the metabolism of Seroquel. For example, inducers of CYP3A4 like rifampicin and carbamazepine can increase the metabolism of Seroquel, leading to reduced drug concentrations and diminished therapeutic effects. On the other hand, inhibitors of CYP3A4 like ketoconazole and erythromycin can decrease the metabolism of Seroquel, leading to increased drug concentrations and a higher risk of adverse effects.
| Factors affecting Seroquel metabolism | Effect on Seroquel metabolism |
|---|---|
| Age | Reduced metabolism in older adults |
| Gender | Slower metabolism in women |
| Genetics | Individual variations in enzymatic activity |
| Drug interactions (CYP3A4 inhibitors) | Increased drug concentrations |
| Drug interactions (CYP3A4 inducers) | Decreased drug concentrations |
In conclusion, Seroquel metabolism occurs primarily in the liver, with the enzyme CYP3A4 playing a major role in drug metabolism. Other factors like age, gender, genetics, and drug interactions can also affect the metabolism of Seroquel, leading to individual variations in drug efficacy and safety.
