Superactive gonadotropin-releasing hormone agonists
Abstract:
Superactive GnRH agonists represent a new class of pharmacologic agents that inhibit reproductive function in both men and women when administered chronically. These hormonal drugs are being tested extensively as both male and female contraceptive agents, as a treatment for prostate cancer, and as a new treatment for idiopathic precocious puberty. Other potential uses include treatment for endometriosis, hirsutism, polycystic ovarian disease, and severe intractable androgen-related acne. This chapter reviews the effects of GnRH agonists on gonadotropin and steroid hormone secretion in both men and women, and assesses the potential of these agents in the varied clinical uses delineated above.

Drug-Receptor Interaction: Agonist
Agonists can bind to receptors in different ways. Some agonists bind directly to the receptor's active site, mimicking the endogenous ligand's action.

Adrenergic Agonists: Mixed-Action Agents
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...
Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Glucagon-like Receptor Agonists
GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
