What is the primary function of preservatives in medical applications?

The primary function of preservatives in medical applications is to increase the shelf life of products. Preservatives play a crucial role in preventing the growth of microorganisms, including bacteria, yeast, and molds that can spoil products or lead to contamination. By inhibiting the development of these microbes, preservatives help maintain the efficacy and safety of medical products over time.

While inactivating saprophytic bacteria is an important aspect of some preservatives, it is not the sole reason they are used in medical applications. Preservatives are intentionally added to extend the usability of products, ensuring they remain safe and effective for longer periods. This aspect is vital in pharmaceuticals and medical supplies, where product stability directly impacts patient care.
