Скачать или смотреть From Mouth to Bloodstream: The Science Behind Oral Drug Absorption

Hello DCT family, and welcome back!

When you swallow a pill, it seems like a simple action. But in reality, that tiny tablet begins a complex journey through the human body.

Before a drug can work, it must survive a series of biological challenges:

• Disintegration of the tablet
• Dissolution of the drug in gastrointestinal fluids
• Crossing the intestinal membrane
• Avoiding cellular transporters that eject it
• Escaping metabolic enzymes that destroy it
• Surviving the liver’s first-pass metabolism

Only a fraction of the drug you swallow actually reaches the bloodstream.

Understanding this journey is fundamental because in the end, it’s all about whether the drug can survive the journey.
