What is tesamorelin approved for?

Tesamorelin, the active ingredient in Egrifta products, is a synthetic growth hormone-releasing hormone analog. Its U.S. indication is reduction of excess abdominal fat in adults with HIV-associated lipodystrophy. The label explicitly excludes weight-loss management. (FDA label)

What does the clinical evidence show?

One pivotal placebo-controlled trial studied 404 people with HIV and excess abdominal fat. At six months, visceral fat changed by -10.9% with tesamorelin versus -0.6% with placebo. The primary endpoint was visceral fat, which is distinct from body weight and fat immediately beneath the skin. Benefits were rapidly lost in participants switched to placebo during the extension. (Falutz et al., 2010)

Evidence grade: high for visceral-fat reduction in the studied HIV population. That grade does not establish benefit for general obesity, anti-aging or athletic performance.

Mechanism and formulations

Tesamorelin stimulates the pituitary growth hormone pathway and raises IGF-1. Egrifta WR and Egrifta SV have different preparation and administration requirements and are not substitutable. A similar hormone mechanism does not make other peptides equivalent medicines. (Current prescribing information)

Safety matters

The label lists contraindications and risks involving malignancy, glucose tolerance, IGF-1, fluid retention and hypersensitivity. Long-term cardiovascular safety has not been established. Read the tesamorelin safety overview and full dossier for evidence and limitations. (FDA label)
