Aviptadil, also known as vasoactive intestinal polypeptide (VIP), is a 28 amino acid neuropeptide that belongs to the glucagon-growth hormone-releasing factor secretion superfamily. Aviptadil acts as a potent systemic vasodilator and bronchodilator. It inhibits the proliferation of vascular and bronchial smooth muscle cells and decreases platelet aggregation. These biological effects are mediated by specific VIP receptors.

References	Vasoactive Intestinal Peptide (VIP) is a neuropeptide, expressed by lymphoid as well as neural cells, which has diverse effects on the cellular mediators of inflammation and immunity and is also a potent neurotransmitter. VIP seems to have a major role in the homeostasis of the respiratory system, while several studies, including clinical trials, suggest that VIP-inhaled agonists could be used in respiratory therapeutics. Mathioudakis A G, Chatzimavridou-Grigoriadou V, Evangelopoulou E, et al. Vasoactive intestinal peptide inhaled agonists: potential role in respiratory therapeutics[J]. Hippokratia, 2013, 17(1): 12. Pulmonary hypertension (PH) leads to an increased right ventricular workload, cardiac failure and death. In idiopathic pulmonary arterial hypertension (PAH) the vasodilating vasoactive intestinal peptide (aviptadil) is deficient. The aim of the present study was to test the acute effects on haemodynamics and blood gases, and the safety, of a single dose of inhaled aviptadil in chronic PH. A total of 20 patients with PH (PAH in nine, PH in lung disease in eight and chronic thromboembolic PH in three) inhaled a single 100-microg dose of aviptadil during right-heart catheterisation. Haemodynamics and blood gases were measured. Aviptadil aerosol caused a small and temporary but significant selective pulmonary vasodilation, an improved stroke volume and mixed venous oxygen saturation. Overall, six patients experienced a pulmonary vascular resistance reduction of >20%. In patients with significant lung disease, aviptadil tended to improve oxygenation. The pulmonary vasodilating effect of aviptadil aerosol was modest and short-lived, did not cause any side-effects and led to a reduced workload of the right ventricle without affecting systemic blood pressure. Aviptadil inhalation tended to improve oxygenation in patients with significant lung disease. Further studies are needed to evaluate the full therapeutic potential of aviptadil aerosol, including higher doses and chronic treatment. Leuchte H H, Baezner C, Baumgartner R A, et al.

Terlipressin Acetate

Terlipressin acetate is a vasopressin analogue with potent vasoactive properties. Terlipressin acetate is a highly selective vasopressin V1 receptor agonist that reduces the splanchnic blood flow and portal pressure and controls acute variceal bleeding. Terlipressin acetate exerts anti-inflammatory and anti-oxidative effects. Terlipressin acetate has the potential for hepatorenal syndrome and norepinephrine-resistant septic shock research.

GLP-1 (7-37) Acetate

Glucagon-like peptide-1 (GLP-1) is an incretin derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-2 as a gut hormone.

GLP-1 (7-36) amide Acetate

Glucagon-like peptide-1 (GLP-1) is an incretin derived from the transcription product of the proglucagon gene. The major source of GLP-1 in the body is the intestinal L cell that secretes GLP-1 as a gut hormone. Its physiological functions include promoting insulin sensitivity, decreasing food intake by increasing satiety in brain and increasing insulin secretion from the pancreas in a glucose-dependent manner.

Argipressin

Vasopressin, also known as arginine vasopressin (AVP), antidiuretic hormone (ADH), or argipressin, is a neurohypophysial hormone found in most mammals. Its two primary functions are to retain water in the body and to constrict blood vessels.

Inquiry
Terlipressin

Terlipressin is a synthetic triglycyllysine derivative of vasopressin with vasoconstrictive, antihemorrhagic, and antidiuretic properties. Upon intravenous administration, terlipressin, an inactive prodrug, is biotransformed to its active moiety, lysine vasopressin (LVP), a nonselective vasopressin analogue with affinity for vasopressin receptors V1 (V1a), V2 and V3 (V1b). As a V1 agonist, terlipressin increases systemic vascular resistance, particularly in the splanchnic area, resulting in a decrease of portal pressure. V1 binding also promotes platelet aggregation and glycogenolysis, while V3 binding induces adrenocorticotropic hormone (ACTH) secretion. Compared to vasopressin, terlipressin has a minimal effect on V2 receptors, which are responsible for promotion of water reabsorption in the collecting ducts of the kidney via stimulation of cyclic AMP production.
