İlaçlara karşı elde edilen yanıtların bireyler veya etnik gruplar arasındaki farklılıklarının nedenini açıklayan araştırma alanı farmakogenetik bilimidir. Genetik farklılıklar nedeniyle ilaçlardan istenen yanıt elde edilemeyeceği gibi, bir takım yan etkiler de ortaya çıkabilir. Hekim olarak en çok arzu ettiğimiz konuların başında hastamızın doğru ilaçla, doğru sürede tedavisinin gerçekleşmesini sağlamak gelmektedir. Fakat bu her zaman mümkün olmamaktadır. Bunun en önemli sebeplerinden biri de ilaçların metabolizmasında rol alan sitokrom P450 (CYP) enzimlerindeki genetik değişikliklerdir. Dolayısıyla hastalara uygulayacağımız ilaçların hangi enzimler aracılığı ile metabolize edildiğini ve hastaların genetik özelliklerini bilmek önem kazanmaktadır. Bu makalede özellikle gastroenteroloji alanında kullanılan proton pompa inhibitörlerinin CYP2C19 gen polimorfizminden nasıl etkilendiği ve klinik yansımaları tartışılmıştır.

Pharmaco-genetic is the science explaining inter-individual and ethnic groups variability for drug responses and its' reasons. Genetic variances might lead side effects besides improper drug response or failed treatment. All clinicians aim to apply correct treatment to patients using correct medication for proper period. However this could not be possible always, which may be mostly caused by genetic variations in P450(CYP) that coordinates the metabolism of drug. Therefore, enzymes that play role in metabolism of drugs to be applied to patients and genetic variations of patients should be known. In this paper we aimed to discuss how the proton-pomp-inhibitors are effected by CYP2C19 gene-polymorphisims and its clinical aspects.
