Definition: The word "antinosarian" is a medical term referring to drugs that mimic the action of human growth hormone (GH). These agents are used in the treatment of conditions such as growth failure, hypoplastic bone density, and osteoporosis. They work by increasing the levels of insulin-like growth factor 1 receptors, which are critical for growth, tissue repair, and differentiation. While they can help manage symptoms, they must be carefully controlled to avoid side effects or toxicities.
