What is tesamorelin used for?

Tesamorelin is used to lower belly fat in patients with HIV.

Description

EGRIFTA SV contains tesamorelin (as the acetate salt), a human growth hormone-releasing factor (GRF) analog. The peptide precursor of tesamorelin acetate is produced synthetically and is comprised of the 44 amino acid sequence of human GRF. Tesamorelin acetate is made by attaching a hexenoyl moiety, a C6 chain with a double bond at position 3, to the tyrosine residue at the N-terminal part of the molecule. The molecular formula of tesamorelin acetate is C221H366N72O67S • x C2H4O2 (x ≈ 7) and its molecular weight (free base) is 5135.9 Daltons. The structural formula of tesamorelin acetate is:

Structural Formula

EGRIFTA SV is a sterile, white to off-white, preservative-free lyophilized powder for subcutaneous injection. After reconstitution with the supplied diluent (Sterile Water for Injection, USP), the solution is clear and colorless. Each single-dose vial of EGRIFTA SV contains 2 mg of tesamorelin acetate and the following inactive ingredients: 20 mg mannitol, USP, 10 mg sucrose, NF, 0.78 mg histidine, USP and 0.05 mg polysorbate 20, NF.

Mechanism of Action

In vitro, tesamorelin binds and stimulates human GRF receptors with similar potency as the endogenous GRF .

Growth hormone-releasing factor (GHRF), also known as growth hormone-releasing hormone (GHRH), is a hypothalamic peptide that acts on the pituitary somatotroph cells to stimulate the synthesis and pulsatile release of endogenous growth hormone (GH), which is both anabolic and lipolytic. GH exerts its effects by interacting with specific receptors on a variety of target cells, including chondrocytes, osteoblasts, myocytes, hepatocytes, and adipocytes, resulting in a host of pharmacodynamic effects. Some, but not all these effects, are primarily mediated by IGF-1 produced in the liver and in peripheral tissues.

Before taking tesamorelin, tell your doctor:

  • If you are allergic to tesamorelin; any part of this medicine; or any other drugs, foods, or substances. Tell your doctor about the allergy and what signs you had.
  • If you have had any of these health problems: Cancer, head injury or radiation to the head, pituitary tumor, pituitary surgery, or problems with the pituitary gland.
  • If you are pregnant or may be pregnant. Do not take tesamorelin if you are pregnant.
  • If you are breast-feeding. Do not breast-feed while you take tesamorelin.
