سیتوکروم P450 2C19 (به اختصار CYP2C19) یک پروتئین آنزیمی است. این آنزیم یکی از زیرخانوادههای CYP2C سیتوکروم P450 سیستم اکسیداز با عملکرد مخلوط است. این زیرخانواده شامل آنزیمهایی است که متابولیسم بیگانهزیستها را کاتالیز میکنند، از جمله برخی از مهارکنندههای پمپ پروتونی و داروهای ضدصرع. در انسان، ژنCYP2C19 پروتئین CYP2C19 را کد میکند. CYP2C19 یک آنزیم کبدی است که روی حداقل ۱۰ درصد از داروهایی که در حال حاضر استفاده بالینی دارند، اثر میگذارد، که مهمترین آنها عبارتند از: داروی ضد پلاکتی کلوپیدوگرل (Plavix)، داروهایی که دردهای همراه با زخم را درمان میکنند، مانند امپرازول، داروهای ضد تشنج مانند مفنیتوئین، داروی ضدمالاریای پروگوانیل و داروی ضداضطراب دیازپام.
