Nesiritide Acetate CAS:114471-18-0

Nesiritide (Natrecor) is the recombinant form of the 32 amino acid human B-type natriuretic peptide, which is normally produced by the ventricular myocardium. Nesiritide works to facilitate cardiovascular fluid homeostasis through counterregulation of the renin-angiotensin-aldoesterone system, stimulating cyclic guanosine monophosphate, leading to smooth muscle cell relaxation.

Neseritide was believed initially to be beneficial for acute decompensated congestive heart failure. It received approval from the United States' Food and Drug Administration for this purpose in 2001 after initial non-approval. In July 2011 the results of the largest study so far for nesiritide was published in The New England Journal of Medicine; it showed that nesiritide was not associated with a change in mortality or re-hospitalizations.

Má hlavne silnú vazokonstrikciu angiotenzínu II a zvýšenie krvného tlaku. Mechanizmus je: 1. Tak, aby telo arteriol kontrakcie hladkého svalstva, zvýšený periférny odpor; 2. Zvýšte teda uvoľňovanie aldosterónu nadobličiek, spôsobujúce zadržiavanie sodíka, zvýšený objem krvi; 3. Priamo prispieva k renálnej tubulárnej reabsorpcii sodíka a vody; 4. Takže mozgová centrálna nervová sympatická vazokonstrikčná aktivita, spôsobuje zvýšenú periférnu vaskulárnu rezistenciu; 5. Stimulujte dreň nadobličiek, aby sa uvoľnil adrenalín a norepinefrín.
