Classically. Hydroxychloroquine HCQ is nearly identical in structure to CQ and has a similar mechanism of action and therapeutic efficacy in rheumatological and infectious diseases. Like CQ, it also has a long half-life, and a very high volume of distribution. 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.

It works through various mechanisms of action, but it primarily works by inhibiting the calcium influx into cardiac and vascular smooth muscle during depolarization. 11 Compared to dihydropyridine drugs, such as nifedipine, that preferentially act on vascular smooth muscle and verapamil that directly acts on the heart muscle, diltiazem displays. Despite widespread clinical use of antimalarial drugs such as hydroxychloroquine and chloroquine in the treatment of rheumatoid arthritis RA, systemic lupus erythematosus SLE and other.
