Chloroquine and hydroxychloroquine, antimalarials, treat various conditions due to anti-inflammatory effects. Careful dosing and eye exams prevent serious retinopathy, ensuring safe use.

Area of Science:

  • Pharmacology
  • Immunology
  • Dermatology

Context:

  • Antimalarials like chloroquine and hydroxychloroquine, derived from quinine, are used beyond malaria.
  • Their anti-inflammatory and immunomodulatory properties support use in diverse pathologies, especially dermatological conditions.

Purpose:

  • To review the established and emerging therapeutic applications of chloroquine and hydroxychloroquine.
  • To evaluate the scientific evidence supporting their use in various diseases.
  • To discuss the safety profile and toxicity, particularly retinopathy, and preventive measures.

Summary:

  • Chloroquine and hydroxychloroquine exhibit anti-inflammatory and immunomodulatory activities, extending their use from malaria to other conditions, including lupus and porphyria cutanea tarda.

  • While evidence is strong for some dermatological conditions, data supporting their use in others like sarcoidosis and polymyositis is limited.
  • Toxicity is generally low, with common side effects including gastrointestinal and mucocutaneous issues. Retinopathy, a serious concern, can be mitigated by adhering to weight-based dosing (6.5 mg/kg for hydroxychloroquine, 4 mg/kg for chloroquine) and regular ophthalmological follow-ups.

    • Impact:

    • Highlights the expanded therapeutic roles of established antimalarials.
    • Identifies gaps in evidence for certain clinical applications.
    • Provides guidance on safe dosing and monitoring to minimize adverse events like retinopathy.
