Guest guest Posted September 20, 2008 Report Share Posted September 20, 2008 Dear Tim, Back in pharm tech school in 1984-1989 I was taught by a pharmacist who is my idol to this day. He told me that most PEDS formulas are such mainly because they do not contain benzyl alcohol and secondly because of max strength or concentration to prevent overdosing. So those we my first and second guesses. He also told us WHY! I pass it on to my students as well. But I had to prove it for you. I knew you were not about to take my 'word' on it. So I gave it my best search ever. I had to go to abou 7 sites to find it. Since I knew what I was looking for it was easy. But the person only looking for strength maynot find it. Here is a bit of background on the drug/hormone analog for those memebers/readers who are not familiar with it: " Initially, LUPRON DEPOT, like other LH-RH agonists, causes increases in serum levels of testosterone to approximately 50% above baseline during the first week of treatment for prostate cancer. " Since this increase in testoserone allows feedback to the hypothalamus, the master gland or pituitary basically shuts off the message to the testes to make testosterone. Testosterone can feed the protstate cancer. The messages are two hormones from the pitutiary gland to the testes called; luteinizing hormone and follicle-stimulating hormone. Eventually these hormone levels drop and no testosterone is made. As an Antineoplastic (anti Cancer) it is a Gonadotropin-releasing hormone (GnRH) analog Leuprolide is a synthetic nonapeptide analog of naturally occurring gonadotropin releasing hormone (GnRH or LHRH). " My words: In precocious puberty, (early puberty usually before age 8) the fall in LH and FSH leads to the ovaries making less estrogen and the testes making less testosterone, thus slowing the progression of puberty. 1. Adult LUPRON DEPOT is usually given IM Depot while Pediatric is usually given subcutaneously. IM has a 4 hour onset and the Ped is a 1 week onset 2. Another difference is in dosing: Prostate Cancer Adult LUPRON DEPOT CAP: 1 mg subcutaneously daily or 7.5 mg I.M. monthly (depot injection). Or 22.5 mg I.M. q 3 months, 30 mg I.M. q 4 months, or one 72-mg implant q 12 months. For endometriosis Adult LUPRON DEPOT can also be given 3.75 mg I.M. monthly or 11.25 mg I.M. q 3 months as a single dose. Recommended duration is 6 months or less. Pediatric Use: See LUPRON DEPOT-PED CPP (leuprolide acetate for depot suspension) labeling for the safety and effectiveness of the monthly formulation in children with central precocious puberty. Testosterone and estradiol are reduced to prepubertal levels in males and females, respectively, and a reduction of gonadotropins will allow for normal physical and psychological growth and development. Natural maturation occurs when gonadotropins return to pubertal levels following discontinuation of leuprolide. Supplied 5mg/1ml Adult for CAP 7.5, 22.5 and 30 mg Ped for CPP 7.5 , 11.25 and 15 mg 3. I found that the Adult Lepron has benzyl alcohol, a preservative that is customarily NOT found in children's formulas. Further the children's formula does not have a warning for it (since it is not in it!) This additive is the MAIN difference between adult and peds formulation of Lupron as well as many other products. " Lepron Peds. The front chamber of LUPRON DEPOT-PED 7.5 mg, 11.25 mg, and 15 mg prefilled dualchamber syringe contains leuprolide acetate (7.5/11.25/15 mg), purified gelatin (1.3/1.95/2.6 mg), DL-lactic and glycolic acids copolymer (66.2/99.3/132.4 mg), and D-mannitol (13.2/19.8/26.4 mg). The second chamber of diluent contains carboxymethylcellulose sodium (5 mg), D-mannitol (50 mg), polysorbate 80 (1 mg), water for injection, USP, and glacial acetic acid, USP to control pH. During the manufacture of LUPRON DEPOT-PED, acetic acid is lost, leaving the peptide. LUPRON DEPOT-PED is packaged as follows: Kit with prefilled dual-chamber syringe 7.5 mg NDC 0300-2108-01 Kit with prefilled dual-chamber syringe 11.25 mg NDC 0300-2282-01 Kit with prefilled dual-chamber syringe 15 mg NDC 0300-2440-01 " " LUPRON INJECTION is a s erile, aqueous solu ion in ended for daily subcu aneous injec ion. I is available in a 2.8 mL mul iple dose vial con aining leuprolide ace a e (5 mg/mL), sodium chloride, USP (6.3 mg/mL) for onici y adjus men , benzyl alcohol, NF as a preserva ive (9 mg/mL), and water for injec ion, USP. The pH may have been adjus ed wi h sodium hydroxide, NF and/or ace ic acid, NF. " " PRECAUTIONS Patients with known allergies to benzyl alcohol, an ingredient of the vehicle of LUPRON INJECTION, may present symptoms of hypersensitivity, usually local, in the form of erythema and induration at the injection site.

Although benzyl alcohol toxicity has been recognized, the concentration necessary for antibacterial action appears to be much lower than the concentration that would be dangerous to adults. Prior to these reports, little was known about the toxic effects of benzyl alcohol in neonates. The possible toxic effects of benzyl alcohol in neonates were noted when several premature infants in neonatal intensive care units developed similar clinical syndromes, referred to as the " gasping syndrome, " characterized by deterioration of multiple organ systems and eventual death. http://pedsinreview.aappublications.org/cgi/content/abstract/6/5/139 " Newborns, especially if critically ill, may not metabolize benzyl alcohol as readily as adults. Reports in the early 1980's of sixteen neonatal deaths associated with the use of saline flush solutions containing benzyl alcohol preservative led to recommendations to avoid its use in neonates. " http://en.wikipedia.org/wiki/Benzyl_alcohol I do hope that this helps. May I ask you what triggered your astute curiosity?

Guest guest Posted September 20, 2008 Report Share Posted September 20, 2008 Thank you, working in medical oncology, and now back to retail, i wanted to know if there was a reason for the 2 different drugs with the same dose, weather or not it was for the company to have 2 brand name drugs for different FDA reason ie zyban & wellbutrin Your the best i know that i can always get the answer i need on here. IS there another list that is more like questions and answer i would hate to impead on the learning process with sometime stupid questions? just wondering keep up the good work -- B.
