Protein bound drug

WebbWhat is protein binding? Well many of the drugs we commonly take and analyze for are protein bound in plasma. A drug can exist in two forms, bound and unbound depending on the drugs affinity for plasma protein. Common blood proteins that drugs bind to are human serum albumin, lipoprotein, glycoprotein, and α, β‚ and γ globulins. Webb1 dec. 2010 · Drug molecules in vivo are either bound to proteins and lipids in plasma (termed plasma protein binding (PPB)), to proteins and lipids in tissues, or are free (that is, unbound) and...
