PhysiologyGastric chyme, which is the mixture of food and gastric juice, is highly acidic due to the presence of hydrochloric acid secreted by parietal cells. The pH typically ranges from 1.0 to 2.0 when it enters the duodenum. This acidity helps to denature proteins and provides the optimal environment for pepsin activity. Once in the duodenum, the chyme is neutralized by the secretion of bicarbonate from the pancreas and bile from the liver.

Oral MedicineWarfarin acts by inhibiting the vitamin K-dependent synthesis of factors II, VII, IX, and X, as well as proteins C and S. This anticoagulant effect decreases the formation of thrombin and fibrin and is used to prevent thrombus formation and embolization in conditions such as atrial fibrillation and heart failure.
