In humans, administration of histrelin acetate results in an initial increase in circulating levels of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), leading to a transient increase in concentration of gonadal steroids (testosterone and dihydrotestosterone in males); however, continuous administration of histrelin acetate results in decreased levels of LH and FSH due to a reversible down-regulation of the GnRH receptors in the pituitary gland and desensitization ...
First-Generation H1 Histamine Receptor Blockers. H1 histamine receptors are found in smooth muscle cells throughout the body, and they lead to a traditional allergic reaction when histamine is bound to them. The first generation of histamine blockers, antihistamines, was developed to counteract the allergic symptoms. The most common example of a first-generation histamine blocker is diphenhydramine (Benadryl). It and other first-generation antihistamines have a documented side effect of extreme sedation.
