title: [Synthetic antimalarials].
abstract: The antimalarials, mainly chloroquine and hydroxychloroquine, derive from the quinoleine core of quinine. Their initial therapeutic indication was the treatment of malaria attacks but, because of anti-inflammatory and immuno-modulatory activities, they have been since used to treat many other pathologies, in particular dermatological ones. For some of these pathologies, lupus or porphyria cutanea tarda for example, the use of these molecules is based on obvious scientific evidence. For other pathologies (cutaneous sarcoidosis, polymyositis, polymorphous light eruption...), the data on the medical literature corroborating the daily clinical practice are extremely poor. Their toxicity is limited. Their most common toxic effects are gastrointestinal (mild nausea or diarrhea) or mucocutaneous (reversible skin or mucosal pigmentation). Their most serious and dreaded side effect, retinopathy, can be largely prevented by using amounts of APS adapted to the weight of the patients. The recommended "safe" daily dose for hydroxychloroquine is 6.5 mg per kilogramme of body weight and for chloroquine 4 mg per kilogramme of body weight. However, at 6- to 12 months intervals, follow-up eye examinations should be performed.
