    It may have both an anti-spirochaete activity and an anti-inflammatory activity, similar to the treatment of rheumatoid arthritis. And caution is required if patients have certain heart conditions, diabetes, psoriasis etc.

    Cytochrome P450 often abbreviated "CYP" is a class of enzymes that is involved in the metabolism of many medications Cytochrome P450 enzymes are located primarily in the liver Cytochrome P450 enzymes are subdivided into classes e.g. 2D6, 3A4, 2C8, etc. based on their structure Oct 18, 2019 Our liver has special enzymes called the cytochrome P450, which have the function of breaking drugs down into smaller bits called metabolites. In this smaller form, our cells can then absorb them better or eliminate them properly. Moreover, drugs such as quinidine which are not substrates for CYP2D6 are also competitive inhibitors of this enzyme 10, 11. Because of the great variety of drugs metabolized by CYP2D6, characterization of potential interacting drugs affecting the activity of this enzyme is clinically important and can improve the safety of drug treatment.

    The most serious adverse effects affect the eye, with dose-related retinopathy as a concern even after hydroxychloroquine use is discontinued. The most common adverse effects are a mild nausea and occasional stomach cramps with mild diarrhea.

    Cytochrome P450 enzymes play a role in the synthesis of many molecules including steroid hormones, certain fats cholesterol and other fatty acids, and acids used to digest fats bile acids. Additional cytochrome P450 enzymes metabolize external substances, such as medications that are ingested, and internal substances, such as toxins that are formed within cells. Cytochromes P450 CYPs are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and breakdown. The cytochrome P450 enzyme system is one of several metabolic systems which evolved to enable organisms to deal with lipid-soluble environmental chemicals. Latterly, the importance of the system in metabolising drugs has been recognised. The cytochrome P450 system performs this function by oxidising, hydrolysing or reducing the chemicals.
