References	We sought to evaluate the efficacy and side effect profile of a small dose of ornipressin, a vasopressin agonist specific for the V1 receptor, administered to reverse the hypotension associated with combined general/epidural anesthesia. A total of 60 patients undergoing intestinal surgery were studied. After the induction of anesthesia, 7-8 mL of bupivacaine 0.5% with 2 microg/kg clonidine and 0.05 microg/kg sufentanil after an infusion of 5 mL of bupivacaine 0.06% with 0.5 microg x kg(-1) x h(-1) clonidine and 0.1 microg/h of sufentanil were administered by an epidural catheter placed at T7-8 vertebral interspace. When 20% reduction of baseline arterial blood pressure developed, patients were randomly assigned to receive, in a double-blinded design, dopamine started at 2 microg x kg(-1) x min(-1), norepinephrine started at 0.04 microg x kg(-1) x min(-1), or ornipressin started at 1 IU/h. Fifteen patients presenting without hypotension were used as control subjects. Beside routine monitoring, S-T segment analysis, arterial lactacidemia, and gastric tonometry were performed. Ornipressin restored arterial blood pressure after 8 +/- 2 vs 7 +/- 3 min in the norepinephrine group and 11 +/- 3 min in the dopamine group (P < 0.05). This effect was achieved with 2 IU/h of ornipressin in most of the patients (11 of 15). Ornipressin did not induce any modification of the S-T segment; however, it significantly increased intracellular gastric PCO(2) (P < 0.05), indicating splanchnic vasoconstriction.

Deslorelin Acetate

Deslorelin acetate is an injectable gonadotropin releasing hormone super-agonist (GnRH agonist) also known as an LHRH agonist. It stops the production of sex hormones (testosterone and oestrogen).

Inquiry
Carperitide

Atrial Natriuretic Peptide (ANP) (1-28), human, porcine is a 28-amino acid hormone, that is normally produced and secreted by the human heart in response to cardiac injury and mechanical stretch. ANP (1-28) inhibits endothelin-1 secretion in a dose-dependent way.

Inquiry
Thymopentin Acetate

Thymopentin, also known as TP-5, is a synthetic derivative of thymopoietin, a thymic hormone, and has immunoregulatory properties. Thymopentin interacts with T cells, reduces endocrine and behavioral responses to experimental stress. It is also found to increase the number of cells undergoing apoptosis in irradiated cells and selectively bind to apoptotic cells.

Inquiry
Antide

Antide acetate (Ac-AA10-NH2) is an LHRH antagonist and represses LH and FSH release from the pituitary gland. It shows a high antiovulatory activity and releases negligible histamine.

Inquiry
Somatostatin

Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS.

Buserelin Acetate is an agonist of gonadotropin-releasing hormone receptor(GnRHR). Buserelin is a synthetic luteinizing hormone–releasing hormone (LHRH) analog.

Inquiry
Angiotensin II Acetate

Angiotensin II is an octapeptide that produced from angiotensin I after the removal of two amino acids at the C-terminal by angiotensin-converting enzyme (ACE). Angiotensin II is mediated by AT1 and AT2 receptors, which are seven transmembrane glycoproteins with 30% sequence similarity.

Atosiban

Atosiban is a nonapeptide, desamino-oxytocin analogue, and a competitive vasopressin/oxytocin receptor antagonist (VOTra). Atosiban is indicated to delay imminent pre-term birth in pregnant adult women. Atosiban is useful in improving the pregnancy outcome of in vitro fertilization-embryo transfer (IVF-ET) in patients with repeated implantation failure (RIF). The pregnancy rate improved from zero to 43.7%.
