The volume of distribution is 1.1 L/kg to 2.1 L/kg, but congestive heart failure can decrease it. About 60% to 80% circulates bound to the protein alpha 1 acid glycoprotein. The oral bioavailability is 35% and the topical bioavailability is 3%. Lidocaine efficacy may be reduced in tissues that are inflamed, due to competing inflammatory ...
