Physiological Plasma Components

“Physiological plasma components” refers to the diverse array of substances dissolved in blood plasma—including proteins (such as albumin, immunoglobulins, and clotting factors), electrolytes, hormones, metabolites, and waste products[1][3][5][7]. This combined mixture is not a drug target itself but provides essential functions: transporting nutrients and wastes, maintaining blood pressure and homeostasis, facilitating immune defense and blood clotting, and serving as biomarkers in many clinical conditions[1][3][4][6]. Some individual plasma proteins (such as clotting factors, albumin, and immunoglobulins) are isolated for therapeutic use or serve as direct drug targets or diagnostic biomarkers[4][6]. However, the term “physiological plasma components” is too broad and non-specific to be considered a molecular target in pharmacology.
