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.

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%.

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
Carbetocin

Carbetocin is a long-acting synthetic agonist analogue of human oxytocin, with antihemorrhagic and uterotonic activities. Upon administration, carbetocin targets, binds to and activates peripheral oxytocin receptors that are present on the smooth musculature of the uterus. This causes uterus contractions and prevents excessive bleeding after childbirth, particularly following Cesarean section, and may be used to decrease blood loss during hysteroscopic myomectomy.

Inquiry
Teduglutide

Teduglutide is a polypeptide consisting of 33 amino acids. It is glucagon-like peptide-2 (GLP-2) analogue that is used for the treatment of short bowel syndrome.

Inquiry
Buserelin Acetate

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

Inquiry
Elcatonin Acetate

Elcatonin acetate inhibits the absorption and autolysis of bones, thus leads to blood calcium descending. In addition, it inhibits the bone salts dissolving and transferring and promotes the excretion of calcium and phosphorus in urine.

Inquiry
Glucagon

Glucagon (Porcine glucagon) is a peptide hormone, produced by pancreatic α-cells. Glucagon stimulates gluconeogenesis. Glucagon decreases the activity of HNF-4. Glucagon increases HNF4α phosphorylation.

Inquiry
Alarelin acetate

Alarelin acetate is a synthetic LH-RH agonist, and stimulates the release of FSH and LH from the pituitary gland. It is known for its induction of ovulation and used to treat endmometriosis.

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.
