Leuprolide Acetate
Leuprolide acetate is a synthetic nonapeptide and analogue of naturally occurring luteinizing hormone releasing hormone (LHRH). It possesses greater biological potency than the natural hormone, which when introduced into the systemic circulation induces the release of luteinizing (LH) and follicle stimulating hormone (FSH) from the anterior pituitary (Schally et al., 1971). It is the blood-borne messenger between the hypothalamus and the anterior pituitary, which controls reproductive function. LHRH is a decapeptide hormone (pGlu-His-Trp-Ser-Tyr-GlyLeu-Arg-Pro-Gly-NH,), which is synthesized and stored in the hypothalamus in neurons which project to the median eminence. LHRH is released in periodic bursts into the hypophyseal portal circulation, where it induces the release of gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH) into the systemic circulation. These factors then produce a trophic and steroidogenic effect upon the gonadal tissues (Rippel et al., 1974; Johnson et al., 1976).
Rough work
Presently, leuprolide is administered by parenteral routes: 11.25- and 22.5-mg, 3-month depot intramuscular injection (Lupron Depot®) and 1-mg daily subcutaneous injection (Lupron®).
The discovery of the releasing hormone brought about the success in the development of highly synthesised potent analogs (Karten et al., 1986)
Chemistry
Leuprolide acetate has three ionizable sites, namely the imidazolyl nitrogen of histidine (pK,
Dosages of the drug vary from one extreme to another based upon the patients needs.

For adults and children 4 years of age and older, the recommended dosage is 2 inhalations (90 mcg of levalbuterol) every 4 to 6 hours; in some patients, 1 inhalation (45 mcg) every 4 hours is recommended.
Three (3) drops, three (3) times a day for three (3) days starting the day before the study.
A nurse should maintain doses administration as per repeated cycle of frequencies every 4 hours or 3 hours per day. Guidelines that facilitate the administration of time-critical
Patients can choose between a once-daily oral dosage form and a more reliable once-monthly injectable dosage form.
The intravenous dosage in this case is 0.5 - 1 mg/kg IV (range: 0.5 - 2 mg/kg).
Gonadotropins are a group of hormones that are secreted by the pituitary gland that starts the production of the gonads. The reason gonadotropins are used in fertility is because it has FSH and LH hormone that aids in producing eggs in order for a woman to ovulate. So in other words, if a women does not have enough hormone to start ovulation she will be given a rFSH for about 12 days to help the eggs mature and then a dose of gonadotropin to start the ovulation process.
What does Luteinizing hormone do to an athlete? This drug helps balance the hormones in both male and female. The side effect of this drug is the same as anabolic steroids(Drug addiction in athletes).
Synthetic cathinone usage is an emergent problem worldwide. Due to their legal status and relative ease to make or obtain, synthetic cathinone usage is hard to document and regulate. Legislature is being implemented across the world, but due to the constant appearance of new derivatives, legislators are having difficulty to make laws regarding the legality of these drugs. There is limited pharmacological and toxicological data known on this class drugs. Additionally, little is known on the pharmacokinetics and the metabolism of these drugs, but researchers are assuming that these drugs follow the same mechanisms that amphetamines due to exit the body because of the close structure relations between these compounds. Pharmacological
The available form of Unituxin is 17.5 mg/mL (3.5 mg/mL) in a single-use vial. Children and Adolescents - 17.5 mg/m2/dose as an IV infusion over 10 to 20 hours on scheduled days for 5 cycles in combination with isotretinoin, sargramostim, and aldesleukin. On cycles 1, 3, and 5: give sargramostim 250 mcg/m2/day subcutaneously (or as an IV infusion over 2 hours) on days 1 to 14; dinutuximab on days 4, 5, 6, and 7; and isotretinoin 160 mg/m2/day PO in 2 divided doses rounded
