Final answer:
4-factor PCC contains four clotting factors, while activated 4-factor PCC contains activated clotting factors, making it more effective in stopping bleeding.
Step-by-step explanation:
4-factor PCC stands for 4-factor prothrombin complex concentrate. It is a medication that contains four clotting factors: factor II, factor VII, factor IX, and factor X. This medication is used to treat bleeding disorders by replacing these clotting factors.
Activated 4-factor PCC is similar to 4-factor PCC but it also contains activated clotting factors. These activated factors help to promote clot formation more quickly, making activated 4-factor PCC more effective in stopping bleeding.
In summary, the main difference between 4-factor PCC and activated 4-factor PCC is the inclusion of activated clotting factors in the latter, which makes it more effective in stopping bleeding.
