Following is a table of selected substrates, inducers and inhibitors of CYP1A2. Inhibitors of CYP1A2 can be classified by their potency, such as: Strong inhibitor being one that causes at least a 5-fold increase in the plasma AUC values of sensitive substrates metabolized through CYP1A2, or more than 80% decrease in clearance thereof.

a Moderate inhibitor causes at least a 2-fold increase in the plasma AUC values, or 50–80% decrease in clearance. [39] a Weak inhibitor causes at least a 1.25-fold but less than 2-fold increase in the plasma AUC values, or 20–50% decrease in clearance. [39] The inhibitors of CYP3A4 are the following substances.
The main route of metabolism for agomelatine is hepatic through the CYP1A2 (90%) and CYP2C9/19 (10%); co-administration of strong CYP1A2 inhibitors (e.g., fluvoxamine) is contraindicated. [46] Agomelatine is well-absorbed with oral administration (≥80%), but it has very low oral bioavailability (~1%) due to extensive first-pass metabolism. [7]
Some pirfenidone is also metabolized by cytochrome P450 enzymes other than CYP1A2. Consequently, strong inhibitors of other cytochrome P450 enzymes such as fluconazole , chloramphenicol , fluoxetine and paroxetine (both CYP2D6) should be used with caution. [14]
The strong CYP2D6 inhibitor thioridazine has been reported to increase trazodone levels by 1.4-fold and concentrations of mCPP by 1.5-fold. [11] [79] Fluoxetine, a strong inhibitor of CYP2D6 and a weak or moderate inhibitor of CYP3A4, [11] [80] has been reported to increase levels of trazodone by 1.3- to 1.7-fold and of mCPP by 3.0- to 3.4-fold.
Cyclophosphamide (CP), also known as cytophosphane among other names, [3] is a medication used as chemotherapy and to suppress the immune system. [4] As chemotherapy it is used to treat lymphoma, multiple myeloma, leukemia, ovarian cancer, breast cancer, small cell lung cancer, neuroblastoma, and sarcoma. [4]
