Ceylon Leadwort - Acetaminophen, Codeine, Doxylamine Interaction Details

There are multiple interactions reported between these two agents.

Interaction Details

Acetaminophen, Codeine, Doxylamine is classified as belonging to the following category: Cytochrome P450 2D6 (Cyp2D6) Substrates

Plumbagin, a constituent of Ceylon leadwort, has been shown to inhibit cytochrome P450 2D6 (CYP2D6) in vitro. So far, this interaction has not been reported in humans. Theoretically, Ceylon leadwort might increase the levels of drugs metabolized by CYP2D6. Some drugs metabolized by CYP2D6 include amitriptyline (Elavil), codeine, desipramine (Norpramin), flecainide (Tambocor), fluoxetine (Prozac), ondansetron (Zofran), tramadol (Ultram), and others.

Interaction Rating

Interaction Details

Acetaminophen, Codeine, Doxylamine is classified as belonging to the following category: Cytochrome P450 1A2 (Cyp1A2) Substrates

Plumbagin, a constituent of Ceylon leadwort, has been shown to inhibit cytochrome P450 1A2 (CYP1A2) in vitro. So far, this interaction has not been reported in humans. Theoretically, Ceylon leadwort might increase the levels of drugs metabolized by CYP1A2. Some substrates of CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), zileuton (Zyflo), zolmitriptan (Zomig), and others.

Interaction Details

Acetaminophen, Codeine, Doxylamine is classified as belonging to the following category: Cytochrome P450 2E1 (Cyp2E1) Substrates

Plumbagin, a constituent of Ceylon leadwort, has been shown to inhibit cytochrome P450 2E1 (CYP2E1) in vitro. So far, this interaction has not been reported in humans. Theoretically, Ceylon leadwort might increase the levels of drugs metabolized by CYP2E1. Some drugs metabolized by CYP2E1 include acetaminophen, chlorzoxazone (Parafon Forte), ethanol, theophylline, and anesthetics such as enflurane (Ethrane), halothane (Fluothane), isoflurane (Forane), methoxyflurane (Penthrane).
