Binding rate of plasma protein
WebMany drugs bind to proteins, primarily albumin, alpha-1 acid glycoprotein, and lipoproteins; protein binding limits distribution of free drug throughout the body. Albumin and total protein concentrations are lower in neonates but approach adult levels by 10 to 12 months. Decreased protein binding in neonates is also due to qualitative differences in binding … WebNov 30, 2024 · During tissue distribution, most organs observed a maximum concentration of curcumol within 0.5-1.0 h.
