Interaction Details
Clopidogrel is classified as belonging to the following category: Cytochrome P450 1A2 (Cyp1A2) Substrates
There is some concern that turpentine oil can inhibit CYP1A2 enzyme activity by up to 90% via induction of inflammation and subsequent downregulation of CYP activity. However, animal research suggests that turpentine oil does not affect the metabolism of phenacetin, a CYP1A2 substrate, despite inducing inflammation.
Some medications metabolized by CYP1A2 include clozapine (Clozaril), cyclobenzaprine (Flexeril), fluvoxamine (Luvox), haloperidol (Haldol), imipramine (Tofranil), mexiletine (Mexitil), olanzapine (Zyprexa), pentazocine (Talwin), propranolol (Inderal), tacrine (Cognex), theophylline, tizanidine (Zanaflex), zileuton (Zyflo), zolmitriptan (Zomig), and others.

Turpentine Oil Overview
Clopidogrel Overview
-
Clopidogrel is used alone or with aspirin to prevent serious or life-threatening problems with the heart and blood vessels in people who have had a stroke, heart attack, or severe chest pain. This includes people who have percutaneous coronary intervention (PCI; angioplasty; a type of heart surgery) that may involve inserting coronary stents (metal tubes surgically placed in clogged blood vessels to improve blood flow) or who have coronary artery bypass grafting (CABG; a type of heart surgery). Clopidogrel is also used to prevent serious or life-threatening problems with the heart and blood vessels in people who have peripheral arterial disease (poor circulation in the blood vessels that supply blood to the legs). Clopidogrel is in a class of medications called antiplatelet medications. It works by preventing platelets (a type of blood cell) from collecting and forming clots that may cause a heart attack or stroke.
