Some medications, like the antibiotic ticarcillin, are not effective if given by mouth because nearly the entire dos is broken down by the liver. These drugs are often injected directly into the bloodstream. Why is this an effective way of administering the medication? Medications injected into the bloodstream can be given at a higher dosage to accommodate for the functions of the hepatic portal system. Medications can be injected directly into the affected tissue and will not have to travel through the hepatic portal system. Medications injected into the bloodstream are in liquid form and will pass through the hepatic portal system without being broken down since it does not contain the acids of the digestive system. Medications absorbed in the digestive tract will enter the hepatic portal system before entering the rest of the systemic system so injections into the bloodstream will allow the medication to travel to the capillary beds and into the tissues before reaching the hepatic portal system.

The liver can metabolize and break down a significant portion of the drug before it reaches the systemic circulation, a process known as the first-pass effect. By injecting the medication directly into the bloodstream, it bypasses the liver initially, allowing it to reach the target tissues more effectively without being extensively metabolized by the liver first.
