References	Ecallantide (Kalbitor [previously, DX-88]; Dyax, Cambridge, MA) is a recombinant protein synthesized in the yeast Pichia pastoris. Ecallantide is a potent and specific inhibitor of plasma kallikrein. In phase 2 trials, symptoms of angioedema improved within 4 hours after treatment with ecallantide.18,21 The Evaluation of DX-88's Effects in Mitigating Angioedema (EDEMA) 3 trial was a randomized, placebo-controlled, phase 3 evaluation of ecallantide for the treatment of acute attacks of angioedema in patients with hereditary angioedema. Ecallantide for the Treatment of Acute Attacks in Hereditary Angioedema Hereditary angioedema (HAE) is a rare, debilitating, and potentially fatal disease characterized by acute attacks of swelling that can affect the abdomen/gastrointestinal tract, larynx, face, genitals, and extremities. Ecallantide is a novel plasma kallikrein inhibitor developed for the treatment of acute HAE attacks. Ecallantide provides relief of acute HAE attack symptoms, with rapidity of response commensurate with therapeutic needs for HAE attack locations.

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
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
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
Buserelin Acetate

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

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
Icatibant

Icatibant (Firazyr) is a synthetic peptidomimetic drug consisting of ten amino acids, and acts as an effective and specific antagonist of bradykinin B2 receptors. It has been approved in the EU for use in hereditary angioedema, and is under investigation for a number of other conditions in which bradykinin is thought to play a significant role.

Inquiry
Deslorelin

Deslorelin is a gonadotropin releasing hormone super-agonist (GnRH agonist) also known as an LHRH agonist. It stops the production of sex hormones (testosterone and oestrogen). It is currently approved for use in veterinary medicine and is used to induce ovulation in mares as part of the artificial insemination process. It is also used to stabilize high-risk pregnancies, mainly of livestock. Unlike other GnRH agonists, which are mainly used to inhibit luteinizing hormone and follicle-stimulating hormone by their ultimate downregulation of the pituitary gland.

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
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
Thymosin β4 Acetate

Thymosin β4 is a 43 amino acid peptide which is regarded as the main intracellular G-actin sequestering peptide. Extracellular thymosin β4 may contribute to physiological processes such as angiogenesis, wound healing and regulation of inflammation.
