Tesamorelinis a synthetic growth hormone-releasing hormone analog used to treat visceral adiposity in HIV-infected individuals with lipodystrophy. Tesamorelin is administered subcutaneously and has significant effects on glucose and lipid metabolism, although it has not been associated with blood aminotransferase increases or clinically visible acute liver impairment. Tesamorelin is a 44 amino acid synthetic polypeptide counterpart of growth hormone-releasing hormone (GHRH). Compared to natural GHRH, the N terminal region of the molecule has been changed to increase its stability and pharmacokinetics.
Tesamorelin activates GHRH receptors in the pituitary, resulting in the creation and release of growth hormone, which affects a variety of cells throughout the body, including hepatocytes, where it increases the production of insulin-like growth factor-1 (IGF-1).
IGF-1 mediates several of the actions of growth hormone, including growth, prevention of programmed cell death, glucose updating, and lipolysis in the liver. Serum IGF-1 levels are often low in people with obesity, diabetes, and, in particular, lipodystrophy. Tesamorelin was tested and shown to be beneficial in reducing visceral adiposity in individuals with lipodystrophy associated with antiretroviral treatment for HIV infection.
Tesamorelin was licensed for use as a medication to decrease extra belly fat in HIV-infected individuals with antiviral drug-related lipodystrophy in the United States in 2010. Tesamorelin is also being studied as a potential treatment for insulin resistance, obesity, and nonalcoholic fatty liver.
Tesamorelin is available as a solution under the trade name Egrifta. The suggested daily dosage is 2 mg administered subcutaneously. Although injection site reactions, itching, arthralgia, myalgia, and peripheral edema are uncommon, they may occur.
Tesamorelin elevates IGF-1 levels, which should be monitored throughout treatment. Potential, unusual side effects include malignant tumor growth promotion, glucose intolerance, diabetes, and hypersensitivity responses.
Tesamorelin injection vial Tesamorelin is a molecule that has been N-terminally modified based on the 44 amino acid sequence of human GHRH. This synthetically modified version is more powerful and stable than the original peptide.
It is also more resistant to dipeptidyl aminopeptidase cleavage than human GHRH. It increases the insulin-like growth factor (IGF-1), which promotes the manufacture and release of endogenous growth hormones.
The released growth hormones then attach to receptors on numerous human organs, regulating body composition. This control is primarily due to the interaction of anabolic and lipolytic processes. However, it has been shown that the primary functions by which Tesamorelin decreases body fat mass are lipolysis followed by triglyceride reduction.
Tesamorelin injection is available as a powder that must be combined with the liquid given with your prescription before being administered subcutaneously (under the skin).
It is typically injected once daily. Use the tesamorelin injection at the same time each day. Follow the instructions on your prescription label exactly, and ask your doctor or pharmacist to clarify any parts you don't understand.
Tesamorelin injection should be used precisely as indicated. Do not use more or less of it, or use it more often than your doctor has suggested.
Before using tesamorelin injection for the first time, read the patient information provided by the manufacturer.
Your medicine is packaged in two boxes: one containing tesamorelin injectable vials and the other containing vials containing liquid to mix with the drug, needles, and syringes.
Follow the instructions of your pharmacist or doctor on how to combine and inject the medicine. See your pharmacist or doctor if you have any concerns regarding injecting this medicine.
Tesamorelin should be injected under the navel into the skin of your stomach (belly button). Tesamorelin should not be injected into the navel or scarred, reddish, irritated, infected, or bruised skin regions.
Tesamorelin should not be injected into any locations with firm bumps from prior injections. To avoid bruising and discomfort, place each injection in a separate part. Keep note of where you inject tesamorelin and avoid injecting it in the same location twice in a succession.
Use the tesamorelin injection immediately after mixing it. After mixing, do not store tesamorelin injection. Throw away any used tesamorelin injections as well as any leftover liquid used to prepare the injection.
Always inspect the tesamorelin injectable solution (liquid) after mixing and before injecting it. The solution should be clear, colorless, and free of particles. If the tesamorelin injectable solution is colored, murky, or includes particles, or if the expiry date on the container has passed, do not use it.
Tesamorelin injection reduces the amount of excess fat in the stomach region in persons with HIV who have lipodystrophy (increased body fat in certain areas of the body).
Tesamorelin injection is not used to assist people in losing weight. Tesamorelin injection belongs to a family of drugs known as human growth hormone-releasing factor (GRF) analogs. It works by boosting the production of a natural chemical that may help reduce body fat. Tesamorelin also has the following benefits:
- Human growth hormone production is increased
- Increases IGF-1 or Insulin Growth Factor-1 without changing glucose levels.
- Triglycerides are reduced.
- Visceral Adipose Tissue (VAT) is reduced
- Carotid Intima-Media Thickness (cIMT) is reduced
- Adults above the age of 60 have improved cognitive.
A drug may have inevitable unintended side effects in addition to its intended benefits. Although not all of these adverse effects are possible, they may need medical treatment if they occur. Consult your doctor right away if any of the following negative symptoms arise:
- Muscle soreness or stiffness that makes it difficult to move
