prescription for leuprolide acetate
in yesterday. It was WAY more expensive than I thought it was going to be. I'm willing to pay that kind of money once, but not twice. It took some investigation to find out why it was so much more than I expected and what I priced online. Right now there is a shortage of the 14-Day kit. (
http://www.ashp.org/Import/PRACTICEANDP ... spx?id=737 ) There are three manufactures of it: Caraco, Teva, and Sandoz. Teva sells the kit for $130, but the other two sell it for TWICE that amount. As of Feb 25, 2001, Teva has manufacturing delays and has not announced an estimated release date. So I'm not for sure what I'll do at the end of the month. I found an online Californian pharmacy that has it in stock, so maybe I'll try them if things seem to go well.
For now I prefer the daily form since I feel more in control and it is possible to either stop right away or more quickly make adjustments. There are options of taking leuprolide in 1, 3, 4, and 6 month increments. I don't think it is well understood on how much you should be taking if you aren't wanting to go ALL the way down and with the long acting forms that might not even be possible. The only possibility I could imagine is trying the monthly 3.75mg dose. After a few days from the intramuscular injection, levels can be found in extremely small quantities… in the single digit ng/dL. It takes very very little of this stuff to act on your pituitary. leuprolide acetate is engineered to be 80 times more powerful than your own GnRH and have a longer half life. The idea is to overwhelm the pituitary and get it to radically down regulate its sensitivity to GnRH.
I suppose with the long acting stuff you could go all the way down and just add testosterone back. But that seems more expensive all the way around. The 1 and 3 month form seem to be the least expensive long acting versions, which are around $330/month at best. Yikes. I'm hoping that if I can secure the daily form with Teva, I will be able to use a 14 day supply over 1 to 1.5 months. That would make it reasonably priced. For this month, I am obviously headed down to at or below castrate levels. I'm pretty sure this will be a new experience and excessive, but I'm willing to test the waters. I've taken depo provera twice and while I never got my testosterone levels measured, I never got hot flashes either. So I'm fairly sure this is going to be a lot further down and in uncharted territory.
I did a bit of research before I committed to trying this and it seems that leuprolide is one of the safest ways to lower testosterone, but it is by no means the cheapest. It is the most expensive from what I can tell! It is not hard on your liver like cyproterone. But like cyproterone, it is way more effective than depo provera if you REALLY want to be down to castrate levels.
I also found a few interesting factoids that I'll share with you. When you first start taking leuprolide it will generally result in a remarkable 50% increase in testosterone of your base line levels. It is referred to as a testosterone flare. But by the end of the week two it should be headed down hard and fast. By week 3, 98% achieve castrate levels, which is considered less than 20 ng/dL. Castrate levels use to be considered less than 50 ng/dL but the availability of more sensitivity testing and comparisons to physical castration made them rethink the acceptable level for prostate cancer victims.
You can take a look at this link for more interesting facts and figures. (
http://www.dovepress.com/six-month-depo ... t-of-a3232 ) It is about a study on the 6 month leupron formation. If the powers that be want me to cut and paste this whole article into this thread, I'm more than willing to do that. But please don't delete this post. LoL.
I thought the two most interesting quotes were:
"Historically, the FDA had established the castrate threshold, or the testosterone level consistent with that obtained after surgical orchiectomy, to be 50 ng/dL.41 However, this was largely based on the sensitivity of available laboratory assays at the time. With the development of newer assay techniques, substantially lower testosterone levels (15 ng/dL) have been observed in men after bilateral orchiectomy, which has led to reassessment of the historical threshold level by the medical community. The National Comprehensive Cancer Network amended its guidelines to suggest that serum testosterone level < 20 ng/dL reflected optimal control of testosterone after surgical or chemical castration, and several other expert opinions have been published on this matter in agreement."
"There was an initial rise in testosterone level, which increased to a mean level of 588 ng/dL by day 2. By day 28, 108 patients (97%) had achieved a serum testosterone level at or below the castrate threshold (50 ng/dL), and 92 (83%) had achieved optimal control of testosterone (<20 ng/dL). After 12 months, 102 of the 103 (99%) patients who completed the study had testosterone levels below castrate threshold, and 91 patients (88%) had optimal control of testosterone. Median time to reach castrate level was 21 days."
One of the most fascinating articles I found was titled "Depot-leuprolide acetate for treatment of paraphilias: a report of twelve cases." You can find the article here.
http://www.ncbi.nlm.nih.gov/pubmed/11446201 . (You probably won't have access, so I'm more than willing to just cut and paste the whole thing into another post in this thread. Just let me know moderators.) I kept thinking "Um wow…" as I read the whole thing. I'm not for sure what was more striking--the content of the article or the author's ability to write serious things with no emotional context at all.
For example here is one case… "Patient #12 was a 25-year-old male with a history of exhibitionism, frotteurism, voyeurism, public masturbation, psychotic disorder NOS, and multiple rapes of women, who had been found not-guilty by reason of insanity for the crime of sexual assault. After incarceration for 3 years pending trial, he was committed to a state mental health facility. He reported continual preoccupation and sexual fantasy of raping and exposing himself to women, which was not affected by fluoxetine intake of up to 80 mg/day. He was started on leuprolide acetate 7.5 mg intramuscularly and maintained on this for 12 months. He reported a loss of all sexual functioning and interest, and in particular of the deviant sexual fantasy and arousal. However, he developed unilateral gynecomastia and complained of the loss of sexual functioning and discontinued the depot-leuprolide acetate. His testos- terone went from a pretreatment level of 525 ng/dl (normal being 286–1511 ng/dl) to a posttreatment of 41 ng/dl at 1 year of treatment. It took 3 months after discontinuation of the depot-leuprolide acetate before the patient’s sexual functioning fully returned. His gynecomastia had not returned 5 months after discontinuation of leuprolide."
I thought this point raised in the discussion part of the paper was interesting too.
"Although long-term treatment with anti-androgens might be necessary to continue reduced sexual arousal (Thibaut et al., 1996), the use of leuprolide acetate for a shorter duration of treatment with a focus of helping an individual obtain control of his sexual impulses and behavior and make use of other treatment modalities is illustrated by some of the cases discussed previously (Patients #1, 2, 5, 8, and 9)."
