MacLean et al. (2015) addresses the efficacy for the GnRH antagonist TAK-385, based on a three-part, placebo-controlled study. The study examined (n=176) healthy UK males, with the age range of 19 to 75 years old. The first part included the dose of TAK-385 20-mg tablets or a placebo. The 14-day part two included the daily dose of TAK-385 20-mg tablets or a placebo. The 28-day part three included the daily dose of TAK-385 20- or 80-mg or a placebo. In part 1, luteinizing hormone (LH) levels decreased, as well as serum testosterone levels. In part 2, with doses of at least 40 mg/d, LH and follicle-stimulating hormone (FSH) levels decreased and after multiple doses the mean testosterone levels dropped below the threshold for medical castration. In part 3, serum testosterone levels dropped most rapidly and medical castration was achieved. Doses greater than 80 mg/d of TAK-385 reduced the serum testosterone levels below castration levels. Conclusively, GnRH is a valid option for testosterone suppression and ultimately serves as an effective prostate cancer hormone therapy treatment. …show more content…
(2012) highlighted a key difference in long term use of monthly GhRH antagonist degarelix (240/80 mg) over LHRH agonist goserelin (3.6mg) in a study that included (n=175) patients completing the trial over 12 weeks. Goserelin treated patients were given bicalutamide (50 mg) in combination on a daily basis for the first 28 days to control hormone flares and related side effects. This study was a randomized parallel-arm, open label, multicenter trial that found the short term efficacy to be the same in both when controlling the total prostate volume (TPV) and relief of lower urinary tract symptoms (LUTS), but more favorable over long term treatment in degarelix patients for LUTS relief. These findings potentially extrapolated the different overall effects on the GnRH receptors in the bladder and prostate with efficacy favoring degarelix in long term

Different treatment plans were assessed, either for nocturia by itself or that occurring in association with BPH. As, BPH is a potential risk factor for nocturia, α blockers are considered a potential treatment for nocturia (11). The α1-blockers are the most common treatment for LUTS/BPH and all currently available α1-blockers have similar efficacy and improve symptoms by approximately 35% and Qmax by 1.8–2.5 mL/s (12, 13). Many studies assessed the effect of α1-blockers, either alone or in combination with 5-α reductase inhibitors on nocturia associated with BPH. Tamsulosin OCAS 0.4 was evaluated in BPH patients with ≥ 2 night voids and was proved to significantly improve the mean IPSS when compared to placebo (14). However, the reduction in nocturnal voids was associated with a minimal difference between tamsulosin and placebo with a mean change of 3.1 to 2.0 night voids for tamsulosin and
Hypothalamic, pituitary, and testicular tissues were collected to quantify mRNA levels using qPCR. Accordingly, KISS1, Kiss1r, and GNRH mRNA levels in the hypothalamus were significantly lower in the treatment group than in the control group (P < 0.05). Immunization with active kisspeptin DNA vaccine suppresses feedback regulation of the gonads in the hypothalamus and synthesis of GNRH in the hypothalamus. It is believed that the kisspeptin- Kiss1r system has been a significant integrator of multiple hormonal and physiological signals with GNRH neurons. Xing-fa et al. [2014] showed that the level of KISS1 mRNA and that of KISS1 receptor Kiss1r in the hypothalamus were notably reduced after immunological or surgical castration. The amount of GNRH mRNA in the arcuate nucleus (ARC) of the hypothalamus and mRNAs of genes in the sex-hormone negative-feedback loops in the hypothalamus were decreased in pregnenolone-immunized rabbits compared to controls. The actions of GNRH are mediated by kisspeptin neurons, which express steroid receptors [García-Galiano et al., 2011].
Benign prostatic hyperplasia (BPH) or commonly referred as enlarged prostate, occurs in more than 50% of men in their sixties and up to 90% in their seventies and eighties. The condition’s hallmark symptoms include frequency, hesitancy, urgency, post void fullness and nocturia. These symptoms can greatly affect quality of life of men who suffer from them. Flomax is one of the medications that help to relieve symptoms of BPH. The drug was developed by Boehringer Ingelheim pharmaceutical company and approved by the Food and Drug Administration (FDA) in 1997. The purpose of this paper is to provide an in-depth discussion of Flomax based heavily on the 21-page long information provided by the pharmaceutical company.
Luteinizing hormone releasing hormone (LHRH) agonists therapy may be used to enhance a negative feedback loop between the anterior pituitary and testicles, thus inhibiting the production of TST. LHRH agonists replicate the effects of endogenous luteinizing hormone which cause an acute rise in TST production — followed by a significant decrease in long term TST levels. LHRH antagonists may be used to disrupt the hypothalamic pituitary axis and inhibit the production of male sex androgens. The therapeutical index of LHRH antagonists may be greater than that of LHRH agonists because they do not cause the acute flare in TST as
Anabolic-androgenic steroid is a family of lipophilic hormone that derived from cholesterol, which includes the natural male hormone testosterone and its synthetic derivatives, such as nandrolone and androsterone (Janjic et al. 2012; Basile et al. 2013). Testosterone is the principle molecule that possesses both anabolic and androgenic properties, which semantically refers to the ability to stimulate the synthesis of complex biological molecules and the growth of masculine characteristics respectively (Quan et al. 2011). The supplement of testosterone has been used in medicine as an effective treatment of hypogonadism or severe muscle catabolism since its discovery. However, due to the poor efficacy in the form of oral medication and
Manage prostate cancer in men – the growth of prostate cancer is stimulated by testosterone hormone, hence, Zoladex is prescribed in men to slow the growth rate of cancer as testosterone levels are decreased.
In 2011 5.3 million prescriptions for male enhancement pills were written in the united states. In the United States prescriptions tripled between 2000 and 2011 with sales as high as 1.6 billion dollars. Men who used testosterone therapy had a 30 percent increased risk of heart attacks, strokes, or dying. The Food Dug Administration or for short the FDA is responsible for making sure products are safe to be on the market. If not there taken off the market. An increasing trend of over the counter products represented as male enhancers may be laced with prescription drugs, controlled substances and untested and unstudied ingredients. With how vast the drug market is the FDA connote test all of the
Tadalafil may also deal with the symptoms of Benign Prostatic Hyperplasia, a common prostate trouble. A sufferer with this crisis administered with a dose of tadalafil showed a statistically awesome improvement. A thorough medical comparison of the sufferer established that Cialis will also be an strong drug for men with benign prostatic
Testosterone replacement therapy, also known as TRT, has become more popular recently. Men, who have lower testosterone levels, can use TRT to improve their energy levels, reinvigorate their sex drives, and stabilize their moods. As the popularity of TRT has risen, however, so have the myths surrounding its use. It is important to sift through the myths surrounding testosterone replacement therapy and get to the truth.
What Can Drive You to Madness and Insanity Madness and Insanity are practically the same thing ,they both mean to be seriously mentally ill. Macbeth,by Shakespeare,is a story of which a man has an opportunity for power,and ends up having to kill and betray several people to be King. His wife was a an enormous part of this,she wasn't always the sweetest and most understanding person. Lots of people believed Macbeth was a good person and all trusted him, which he have remorse for his actions, but on the other hands things do take a few wrong turns. William Shakespeare, author of the play Macbeth, uses insanity to reveal maddening forces of power, a stressful wife, and constant guilt.
In breast cancer, the estrogen-estrogen receptor complex cause cell proliferation (Frank, 2013). Hormone therapies can target the effects of hormones in two ways: 1) by stopping the production of estrogen and testosterone, reducing their levels, and 2) by binding to the hormone receptor and blocking the hormone from binding (Frank, 2013). In breast cancer, drugs such as Lupron “prevent the ovaries from making estrogen by blocking cues from the brain that regulate the ovaries” (Frank, 2013). In prostate cancer, Lupron works the same way to prevent the testes from producing testosterone (Frank, 2013). Drugs such as tamoxifen (breast cancer) and flutamide (prostate cancer) bind to their respective hormone receptors and bloc the hormone from
Deliberate practice is the ability to make oneself able to practice on a regular basis. This can apply to virtually anything that you would need to get better in. Deliberate practice also includes the ability to set a specific goal. This goal is used for getting to a certain point that will make you better at the thing you are practicing. You’ll also need a teacher to help you see mistakes that you can then go and fix while you’re practicing. With all of these things combined you’ll set a strong foundation for you to be able excell in your topic of work.
Nike has been accused of the unfair labor practice of sweatshop labor. A sweatshop is a place with hazardous working environments, extreme temperatures and abusive employers, hence the term sweat shop. Sweatshop workers work long days exceeding 14 hours and earn less than the living wage (Britanica, n.d.). While these conditions may be shocking to Americans and Modern Western Nations the notion of abusive working conditions is more attractive to Asians and South Americans who are faced with the stark choice of terrible working conditions or unemployment and possible death by starvation. The accusation then is that Nike is using these labor condition inequalities to take unethical
Since BPH cannot be cured treatment is focused on reducing symptoms. Deciding how to treat BPH depends on how bothersome the symptoms are. The American Urological Association symptom index is an interactive questionnaire that can help to identify how bad the patient’s symptoms are and guide treatment. Symptoms that are mild or do not bother the patient may benefit from just watching them. Treatment of moderate to severe symptoms depends on how bothersome they are to the patient. For those who feel their symptoms are bothersome, surgery maybe an option or less invasive therapies such as transurethral microwave therapy or transurethral needle ablation. Complications of BPH such as inability to urinate, urinary tract infection, bladder stones, kidney damage, or ongoing blood in the urine should be treated with surgery. Alpha blockers relax the muscles of the prostate and bladder improving urine flow and can be used in men with moderate to severe BPH. Men with very large prostate glands may benefit from 5-alpha reducatase inhibitors which block the production of dihydrotestosterone. Combination therapy maybe used for patients with overactive
