    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 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. Hydroxychloroquine has similar pharmacokinetics to chloroquine, with rapid gastrointestinal absorption and elimination by the kidneys. Cytochrome P450 enzymes CYP2D6, 2C8, 3A4 and 3A5 metabolize hydroxychloroquine to N-desethylhydroxychloroquine. Pharmacodynamics. Antimalarials are lipophilic weak bases and easily pass plasma membranes. Cytochromes P450 CYP are a major source of variability in drug pharmacokinetics and response. Of 57 putatively functional human CYPs only about a dozen enzymes, belonging to the CYP1, 2, and 3 families, are responsible for the biotransformation of most foreign substances including 70–80% of all drugs in clinical use.

    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.

  6. 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.

    Abstract. Background The American Academy of Ophthalmology recommendations on screening for chloroquine CQ and hydroxychloroquine HCQ retinopathy are revised in light of new information about the prevalence of toxicity, risk factors, fundus distribution, and effectiveness of screening tools. Cytochrome P450 CYP enzymes play major roles in drug metabolism. Certain single‐nucleotide polymorphisms SNPs in CYP genes may have a large impact on CYP enzyme activity. HCQ is metabolized to N‐desethyl HCQ DHCQ in the liver through the N‐desethylation pathway 10, 11. Cytochrome P450 enzymes, also called CYP enzymes, and membrane transporters are the most common mechanisms for affecting drug absorption, distribution, metabolism, and excretion also known as ADME.
