Hydroxychloroquine Alternatives for Chronic Disease: Response to a Growing Shortage Amid the Global COVID-19 Pandemic

Abstract

With the emergence of a novel severe acute respiratory syndrome coronavirus, investigators worldwide are scrambling to identify appropriate treatment modalities, develop accurate testing, and produce a vaccine. To date, effective treatment remains elusive. Chloroquine phosphate and hydroxychloroquine sulfate (HCQ), well-known antimalarial drugs effective in the treatment of systemic lupus erythematosus, rheumatoid arthritis, porphyria cutanea tarda, and chronic Q fever, are currently under investigation. The United States Food and Drug Administration recently issued an Emergency Use Authorization for CQ and HCQ use in the treatment of coronavirus disease 2019 (COVID-19). With spikes in HCQ use and demand, ethical considerations encompassing appropriate use, patient autonomy, nonmaleficence, and distributive justice abound. As drug experts, pharmacists are uniquely positioned to advocate for patients with chronic conditions necessitating HCQ use, assist in the appropriate prescribing of HCQ for COVID-19, and ensure patients and health care professionals are continually educated during this public health crisis. This review highlights the worldwide pandemic, describes appropriate HCQ use for chronic conditions, highlights available alternatives, and deliberates evolving ethical questions. With assistance from colleagues, state boards of pharmacy, and national organizations, pharmacists ensure the just distribution of valuable pharmaceuticals to patients having COVID-19 while supporting the needs of patients requiring HCQ for chronic conditions.
