Background

Hydroxychloroquine is a racemic mixture consisting of an R and S enantiomer. Hydroxychloroquine is an aminoquinoline like chloroquine. It is a commonly prescribed medication in the treatment of uncomplicated malaria, rheumatoid arthritis, chronic discoid lupus erythematosus, and systemic lupus erythematosus. Hydroxychloroquine is also used for the prophylaxis of malaria in regions where chloroquine resistance is unlikely. It was developed during World War II as a derivative of quinacrine with less severe side effects. Chloroquine and hydroxychloroquine are both being investigated for the treatment of SARS-CoV-2.

The FDA emergency use authorization for hydroxychloroquine and chloroquine in the treatment of COVID-19 was revoked on 15 June 2020.

Hydroxychloroquine was granted FDA approval on 18 April 1955.

A recent study reported a fatality in the group being treated with hydroxychloroquine for COVID-19.

Indication

Hydroxychloroquine is indicated for the prophylaxis of malaria where chloroquine resistance is not reported, treatment of uncomplicated malaria (caused by P. falciparum, P. malariae, P. ovale, or P. vivax), chronic discoid lupus erythematosus, systemic lupus erythematosus, acute rheumatoid arthritis, and chronic rheumatoid arthritis.
