Circulating plasma components

Circulating plasma components encompass the diverse array of proteins, electrolytes, hormones, and nutrients found within the liquid portion of the blood. This category includes critical functional elements such as albumin, which maintains oncotic pressure and transports ligands, and coagulation factors essential for hemostasis [1]. While not a single therapeutic target, these components are frequently the focus of medical interventions, including plasma exchange therapy to remove pathogenic autoantibodies or toxins, and the administration of plasma-derived products to treat deficiencies [3]. Drugs often interact with these components through non-specific binding, which significantly influences their pharmacokinetics, half-life, and bioavailability [2]. Consequently, alterations in the composition of circulating plasma can lead to various pathological states, including edema, bleeding disorders, and impaired drug clearance. Understanding the interaction between drugs and these components is vital for predicting therapeutic efficacy and avoiding toxicity.
