Alopecia Universalis in an Elderly Chinese Man Induced by Sacubitril/Alisartan, a Novel Angiotensin Receptor-Neprilysin Inhibitor.

Drug-induced alopecia areata is a rare adverse event wherein medications such as antimicrobials, anticonvulsants, and biologics, trigger the premature transition of actively growing hairs into the telogen phase. Herein, a unique case of alopecia universalis observed during a clinical trial involving sacubitril/alisartan, a novel angiotensin receptor-neprilysin inhibitor (ARNI) has been reported. This case contributes to the range of cutaneous reactions that might be observed in association with ARNI therapy.
