👉 A carrier fluid is a medium used to transport and distribute other substances, such as drugs or chemicals, within the body. In the context of drug delivery systems, carrier fluids are often biological fluids like blood, lymph, or interstitial fluid that facilitate the movement of therapeutic agents from their site of administration to their target tissues. These fluids can enhance the bioavailability, distribution, and efficacy of drugs by ensuring they reach the intended site more effectively. Carrier fluids can also help in reducing side effects and improving patient compliance by enabling non-invasive or minimally invasive delivery methods.
