Amphiphilic Myopathy Induced by Hydroxychloroquine Presenting with Dysarthria / 대한신경근육질환학회지

ABSTRACT

Chloroquine and hydroxychloroquine (HCQ) are commonly used antimalarial agents as the treatment for a wide range of autoimmune disorders including dermatological, rheumatoid, and connective tissue diseases. These amphiphilic drugs can cause toxic myopathy in in patients which are commonly characterized as reversible proximal muscle weakness, dysphagia and dyspnea. Herein, we report a case of a patient on HCQ, who suffered from toxic myopathy presenting as proximal muscle weakness and dysarthria, which was fully recovered after the cessation.
