The steady-state pharmacokinetics and renal clearance of guanfacine were studied in patients with renal insufficiency. Apparent total body and renal clearances of guanfacine, as well as apparent volume of distribution, decreased in parallel with the decline in renal function. Higher plasma levels of guanfacine were observed in patients with GFR less than 30 ml/min. The steady state t 1/2 of guanfacine in the presence of renal insufficiency was insignificantly prolonged relative to that observed in the presence of normal renal function and appeared to be independent of the degree of renal insufficiency.

UI MeSH Term Description Entries
D007328 Insulin A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).
