    Viagra timeline


    Given the success of drugs to treat erectile dysfunction, such as sildenafil (Viagra), tadalafil (Cialis) and vardenafil (Levitra), drug companies have sought a comparable drug for women. Viagra has even been tried as a treatment for sexual dysfunction in women. However, the Food and Drug Administration (FDA) hasn't approved this use of Viagra. Indeed, until recently there were no FDA-approved drugs for treating sexual arousal or sexual desire problems in women. A prescription medication known as flibanserin (Addyi) — originally developed as an antidepressant — has been approved by the FDA as a treatment for low sexual desire in premenopausal women. A daily pill, Addyi may boost sex drive in women with low sexual desire and who find the experience distressing. Potentially serious side effects include low blood pressure, dizziness and fainting, particularly if the drug is mixed with alcohol. Experts recommend that you stop taking the drug if you don't notice an improvement in your sex drive after eight weeks. Sexual problems may be due to difficulties with arousal, a lack of desire or both. For example: If you're experiencing changes or difficulties with sexual function, consult your doctor. In the early 1990’s Pfizer’s researchers were hoping that sildenafil citrate would prove to be helpful as a heart disease treatment, but clinical trial participants revealed an unexpected side effect. Food and Drug Administration (FDA), it was estimated that more than 40,000 prescriptions for the little blue pill were filled.[1] Faced with patent expiration in 2012, Pfizer filed a “method of use” patent, which extended patent protection through April 2020. As a result, their focus shifted, and Viagra was approved for erectile dysfunction (ED) in 1998. However, several legal battles ensued and in 2013, Pfizer settled with Teva Pharmaceuticals, allowing the generic drug manufacturer to launch its version of the pill in December 2017, paying slight royalties until the patent expires.[2] Brand or generic, the drug works just the same: As a phosphodiesterase-5 inhibitor, Viagra works by relaxing the muscles found in the walls of blood vessels, increasing blood flow to particular areas of the body. The branded Viagra and the generic both share the same active ingredients and are equivalent in terms of clinical effectiveness and interchangable. As age increases, so does prevalence of ED: Several studies report the prevalence of erectile dysfunction at 52%, a rate that tends to increase with age. For example, 40% of 40 year olds report suffering from ED, whereas 70% of 70 year olds report the same.[3] Brand will cost less than generic: The average wholesale price (AWP) for a 30-day supply (six pills) of Viagra is $435. The generic version is estimated to cost $370, a savings of $65. However, rebates and discounts that Envision Rx negotiated on the brand reduce the net cost, providing approximately $130 in savings for a 30-day supply of the brand medication.

    When you use retinoids regularly, your skin tone will be firmer, skin texture smoother, and your overall complexion will be brighter. Retinoids can increase collagen production, and some evidence shows they may increase elastin production as well. As you can imagine, this makes retinoids effective anti-agers and are used to prevent and reverse signs of aging. These aren't the only topical retinoids available, though. Retin-A Micro (tretinoin), Renova (tretinoin), Tazorac (tazarotene) are all retinoids. Differin, the once prescription-only acne medication that is now available over the counter, is often lumped into the retinoid-group. Although the active ingredient in Differin (adapalene) isn't technically a retinoid, it works largely the same way. Buy Retin-a-cream Online From Canada Drugs Direct Brand.
