This drug is also effective at preventing lupus flares. Macology, mechanisms of action and potential toxicity of these drugs. Pharmacology of hydroxychloroquine and chloroquine Hydroxychloroquine is very similar to chloroquine except for the addition of a hydroxyl group to the side chain and b-hydroxylation of the N-ethyl substituent. Hydroxychloroquine is administered orally and, like The efficacy of antimalarials, especially hydroxychloroquine HCQ, in preventing systemic lupus erythematosus SLE flares is well demonstrated. However, many studies show that the percentage of SLE patients treated with HCQ remains low.

The mechanisms of action of hydroxychloroquine and chloroquine remain under continuous study in modern molecular medicine 17,18 using advanced tools in computational biology 19, synthetic biology. An array of cytochrome P450 enzymes converts hydroxychloroquine into its active metabolite, desethyl hydroxychloroquine. 6 The onset of action may take up to 4–6 weeks post‐commencement of therapy, and it may take 3–6 months to achieve maximal clinical efficacy.
