DescriptionStabilized synthetic peptide analogue of Growth Hormone Releasing Hormone (GHRH). It is used to treat excess abdominal fat in HIV-infected patients with lipodystrophy. It is a metabolic condition characterized by insulin resistance, fat redistribution and hyperlipidemia associated with antiretroviral therapy for HIV infection.
Indication/DiseaseTesamorelin acetate is a synthetic analogue of human hypothalamic Growth Hormone Releasing Factor (hGRF) indicated to induce and maintain a reduction of excess abdominal fat in HIV-infected patients with lipodystrophy.
PharmacodynamicsTesamorelin stimulates growth hormone secretion, and subsequently increases IGF-1 and IGFBP-3 levels.
Mechanism of ActionBy acting on the pituitary cells in the brain, tesamorelin stimulates production and release of the endogenous hormone (hGRF). Tesamorelin therapy predisposes the patient to glucose intolerance and can also increase the risk of type 2 diabetes, so the drug is contraindicated in pregnancy.
ToxicityDiarrhea, congestive heart failure, peripheral neuropathy, and loss of mobility were the four serious adverse events reported during the clinical studies
MetabolismNo formal metabolism studies have been performed in humans.
AbsorptionThe absolute bioavailability was determined to be less than 4% in healthy adult subjects following a 2 mg subcutaneous dose.
Volume of Distribution9.4±3.1 L/kg in healthy subjects.10.5±6.1 L/kg in HIV-infected patients.

Brand DiscriptionEGRIFTA contains tesamorelin (as the acetate salt), an analog of human growth hormone-releasing factor (GRF). 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.
Prescribed forexcess abdominal fat in HIV-infected patients with lipodystrophy
