Infliximab is stable in which solution only?

Dextrose solution
Sterile water
Normal saline
Ringer's solution

The correct answer is: Normal saline

Infliximab is a monoclonal antibody medication that is used to treat various autoimmune diseases. It is important to note that infliximab is stable in normal saline solution only. Normal saline (0.9% sodium chloride solution) is isotonic, which means it has the same tonicity as human blood and is compatible with most medications. As for the other options: - Dextrose solution (Choice A) is not an appropriate choice as it may lead to instability of infliximab due to the presence of glucose. - Sterile water (Choice B) lacks the necessary electrolytes and may cause instability. - Ringer's solution (Choice D) contains additional electrolytes which may interact with infliximab and lead to instability. Therefore, normal saline is the most suitable solution for infliximab due to its compatibility and ability to maintain the stability of the medication.
