مقدمه: بررسی اثر نواسانات نرخ ارز بر تراز پرداخت‌ها از اهمیت ویژه‌ای در ادبیات اقتصادی برخوردار است. یکی از زیر بخش‌های تراز پرداخت‌ها، تراز پرداخت دارویی می‌باشد. این مطالعه به دنبال شناسایی اثرات تغییر نرخ ارز بر تراز پرداخت صنعت دارویی ایران می‌باشد. روش پژوهش: برای بررسی موضوع حاضر از روش تصحیح خطای برداری استفاده شده و به این منظور از داده‌های آماری طی سال‌های 1391-1371 استفاده شده است. یافته‌ها: نتایج تحقیق نشان می‌دهد که وجود منحنی جی در تراز پرداخت این صنعت مورد تایید است. به طوری‌که با افزایش نرخ ارز، تراز پرداخت صنعت دارویی در دوره‌های ابتدایی رو به وخامت گذاشته و بعد از گذشت چند دوره، افزایش نرخ ارز، باعث افزایش درآمدهای صادرات کشور از این صنعت شده و تراز پرداخت بهبود می‌یابد. با توجه به نتایج تجزیه واریانس می‌توان اذعان نمود که تغییرات صادرات و واردات صنعت دارویی به‌صورت عمده ناشی از تغییرات نرخ ارز بوده و به ترتیب0/19 و 0/016 تغییرات توابع مذکور ناشی از تغییرات نرخ ارز بوده است. همچنین تغییرات تراز پرداخت این صنعت ناشی از تغییرات درآمد خارج کشور می‌باشد و میزان اثر پذیری از تغییرات درآمد خارج 0/25 می‌باشد. نتیجه‌گیری: افزایش نرخ ارز باعث بهتر شدن تراز تجاری صنعت دارویی کشور در دوره‌های پایانی شوک‌های ارزی شده است. همچنین تغییرات تولید ناخالص خارج از کشور بیشترین تاثیر را بر نوسان تراز تجاری دارویی ایران داشته است.
