NexMed, Inc. (Nasdaq: NEXM), a specialty CRO and a developer of products based on the NexACT® technology, announced today that it received a Notice of Non-Compliance ("Notice") as part of the review process from Health Canada for its New Drug Submission ("NDS") for the Vitaros erectile dysfunction treatment filed in February 2008. The deficiencies cited related to the product's CMC (Chemistry, Manufacturing and Controls). There were no pre-clinical or clinical deficiencies cited in the Notice. The Notice is a routine end-of-review communication from Health Canada when additional information is needed to reach final decision on product approval. Viagra Canadian Pharmacy Buy viagra Canada Antidepressants: Many different drugs, including Prozac, Zoloft, Elavil, and Wellbutrin, are used to treat depression. Some antidepressants can worsen ED, so be honest with your doctor about your condition so that he or she can prescribe an appropriate treatment. While pulling back may not be helpful, trying harder isn't the answer either. Indeed, while many women jump ship in troubled waters, others take the opposite approach and try to drown their mate in eroticism, believing the problems will disappear if they simply try harder. Not only is this not true, experts say this approach can make things worse. Nutritional Supplements: nutritional supplements including the amino acid arginine, bioflavonoids, zinc, Vitamin C, Vitamin E, and flaxseed meal have been used to improve erectile function. In addition, certain ED patients with low levels of the hormone dehydroepiandrosterone (DHEA) showed improvement in erectile function after receiving supplemental doses of DHEA. However, because the long-term safety of DHEA is not known, most experts do not recommend its use. "It has a long way to go, but the researchers have basically shown they can take cells from an organ, culture them, put them back in and have them be functional," McCullough said. "This is especially impressive because the penis is an organ that's a very sensitive hydraulic pump, so to speak. During an erection, blood has to flow into the organ. The organ then has to expand and then shut down the drainage so the blood doesn't flow back out. And all of these things are very interrelated." Metabolism (breakdown) of sildenafil is slowed by aging, liver and kidney dysfunction, and concurrent use of certain medications (such as erythromycin--an antibiotic, and protease inhibitors, for HIV). Slowed breakdown allows sildenafil to accumulate in the body and potentially may increase the risk of side effects. Therefore in men over 65, in men with substantial kidney and liver disease, and in men who also are taking protease inhibitors, the doctor will initiate sildenafil at a lower dose (25 mg) to avoid accumulation of sildenafil in the body. A protease inhibitor ritonavir (Norvir) is especially potent in increasing the accumulation of sildenafil, thus men who are taking Norvir should not take sildenafil doses higher than 25 mg and at a frequency of no greater than once in 48 hours. Vacuum constriction devices should not be used by men who may have a significant congenital bleeding disorder or a disorder that predisposes them to a condition called priapism (a prolonged, sometime painful erection lasting over several hours). Examples include sickle cellanemia, some forms of leukemia, and other blood conditions. Viagra® is absorbed and processed rapidly by the body and is usually taken 30 minutes to 1 hour before intercourse. Results vary depending on the cause of erectile dysfunction, but studies have shown that Viagra is effective in 75% of cases. It helps men with erectile dysfunction associated with diabetes mellitus (57%), spinal cord injuries (83%), and radical prostatectomy (43%). Treatment Strategies Couples who cannot talk to each other are likely to have problems with sexual intimacy. Men who have trouble communicating their feelings may find it difficult to share with their partner any anxieties about their sexual performance. In these circumstances, counseling can be very helpful for both you and your partner. Rash "There are certain cardiovascular drugs that have the potential to induce impotence," he says. For example, medications used to treat high blood pressure can also cause erectile dysfunction. So can other medications, such as those used to treat depression. DATA SOURCES: Primary research and review articles were identified through a search of ScienceDirect, PubMed/MEDLINE, and International Pharmaceutical Abstracts (1990–August 2004). The following search terms were used in the Medicine Dentistry and Pharmacology, Toxicology, and Pharmaceutical Sciences subcategories: phosphodiesterase 5 inhibitor, PDE5 inhibitor, erectile dysfunction, sildenafil, vardenafil, tadalafil, prostatectomy, and diabetes. Web of Science (1990–August 2004) was used to search for additional abstracts using the same search terms as above. The package inserts for sildenafil, vardenafil, and tadalafil were also consulted. Numerous indigenous cultures rely on botanical remedies for erection matters and sexual enhancement. Though some have build-believe outcomes, several herbs have physiological proofs, that have been proved medically to possess good effects. [edit] Controversial and unapproved treatments The research doesn't prove that one of the disorders causes the other. And something else -- perhaps a third disease that boosts the risks of both -- could explain the link.
