How it works
You may feel uncomfortable disclosing your erectile dysfunction to your doctor or pharmacist face-to-face. Therefore, it is great that you can now buy Viagra online buy completing an online questionnaire. Purchasing Viagra online can be convenient and discreet, but, as is with buying any other medication online, it is important you do it safely and only buy prescription medicines online from online pharmacies that are regulated. Although it may be convenient, this is not usually an option for prescription-only medication like Viagra. In order to buy an erectile dysfunction medicine in a pharmacy, you usually need to have a prescription from a doctor because Viagra can be dangerous if taken by men who are not medically suitable for it.
Traditional film-coated tablets
You should be careful when buying online to buy erectile dysfunction treatment such as Viagra only from regulated pharmacies for your own safety. Although it may be convenient, this is not usually an option for prescription-only medications that contain Sildenafil Citrate. Viagra is the most well-known member of a class of medications called phosphodiesterase type 5 (PDE-5) inhibitors. The PDE5 inhibitors, including Viagra, help men to get or maintain a suitably hard penile erection. In response to sexual stimulation, Viagra increases the blood flow to the penis and creates a hard erection ready for sexual intercourse.
Which ED Drug Is Best?
Sildenafil Citrate is the active ingredient in Viagra and as such the generically labelled Sildenafil is medically equivalent to Viagra. Sildenafil is equally effective and subject to the same rigorous safety and quality standards as Viagra, but available at a lower price because it is “unbranded”. The dose of Viagra is usually 50 mg taken approximately 1 hour before sexual activity. Some men may find this dose effective, but experience unwanted side effects, in which case 25 mg may be adequate in the future. If 50 mg proves ineffective on four separate occasions and there are no unwanted side effects, then the dose can be increased to 100 mg. Sildenafil is a PDE5 enzyme inhibitor, meaning it works by allowing blood vessels to expand and relax.

The tablet should be swallowed whole with a glass of water approximately one hour before sexual intercourse. Taking the treatment with food can delay the onset of action. Only one treatment should be taken per day (24 hour period); taking it more often increases the risk of side effects and does not make it more effective.

Viagra will remain in the body for approximately 4 hours, with the range between men being usually 3 – 5 hours. This does not mean you will have an erection for this long, but as it works in response to sexual stimulation, this is the timeframe it is likely to be effective. Viagra is generally very well tolerated by most men and the variety of available doses enables men to titrate the treatment to effect without unwanted side effects. For those who do experience side effects, the most common are headache, flushing, indigestion, nasal congestion, nausea, dizziness, and visual disturbances.

Design of study: Systematic review and meta-analysis. Setting: All published or unpublished randomised controlled trials comparing sildenafil with a placebo or alternative therapies. Method: Published studies were sought by computerised searches of electronic databases using the keywords 'sildenafil' and 'Viagra'. A hand search was also done of the British Medical Journal, Lancet, Journal of the American Medical viagra tablet for sex Association, New England Journal of Medicine, British journal of General Practice, Drug, Inpharma and Scrip. An assessment of quality of all identified studies and data extraction was undertaken independently by two researchers. Clinically proven to help you get an erection when you need it.
5. Avanafil
Results were combined in a meta-analysis where appropriate, using RevMan version 3. All trials showed a statistically significant improvement in erectile or sexual function in patients using sildenafil compared with a placebo. A meta-analysis of 16 trials reporting a global efficacy response showed that men were 3.57 (95% CI = 2.93-4.43) times as likely to have improved erections on sildenafil compared with those on a placebo. The number needed to treat to have one man with improved erections was two. The drug has a relatively safe side-effect profile. Tadalafil works by inhibiting the PDE5 enzyme, which is responsible for smooth muscle contraction within the blood vessels. Taking Tadalafil enables the blood vessels in the penis to expand, meaning that blood flow is improved in the place it matters, when you need it most.Tadalafil makes it easier to achieve firmer erections – but only when you’re also naturally aroused.
