Usually, CQ and HCQ are administered as phosphate and sulphate salts, respectively, and both drugs are absorbed in the upper intestinal tract. However, clinically, HCQ is more frequently used than CQ for its lesser toxicity [11]. Both molecules give mild nausea, stomach cramps, gastrointestinal upset, and mild diarrhoea as adverse effects and long-term usage determines loss of retinal function and severe retinopathy. These drugs are used, to date, in malaria patients and in several inflammatory diseases like rheumatoid arthritis, Sjögren syndrome, dermatomyositis, and systemic lupus erythematosus [7,8,10].
