Sildenafil citrate is a phosphodiesterase 5 (PDE5) is a chemical reagent used in the treatment of erectile dysfunction. It was approved for use in 1998, an international corporation FDA.

Sildenafil inhibits PDE5, which leads to an increase in blood vessels of the penis, which can result in a naturally achieved erection when a man is sexually stimulated.

Sildenafil in New Zealand is a generic version of Viagra. The drug has the same characteristics as its brand counterpart, but costs much less thanks to the absence of necessity to pay for months of researching and other expenses which ultimately affects the cost of the medicine. Sildenafil in New Zealand is marketed under various generic names, like Kamagra NZ, Viagra Professional, Viagra Super Active, Kamagra Oral Jelly, and many more.

Sildenafil is much stronger than other types of PDE5 inhibitores and this is a concern about the possible side effects. For example, Viagra can inhibit PDE3, which is involved in the management of heart. Sildenafil also inhibits PDE6, an enzyme in the retina, leading to anomalies associated with vision.

The most important concern of the modern pharmacology is structural analogues of Viagra. Structural analogues are chemical compounds with a slightly altered chemical structure. Structural analogues of Viagra have similar effects on the body, but do not fall under the requirements of the FDA and may thus have unknown or adverse side effects. In one study, published in the Life journal, there had been carried out an analyses of sildenafil generics and it had been found to contain undeclared synthetic inhibitors of PDE5. Many jurisdictions have laws against drug analogues, but Viagra NZ generics are complete chemical analogues of the brand sildenafil citrate in the structure of Viagra by Pfizer.

The most commonly reported side effects of generic Viagra include headaches, upset stomach, and runny nose. Other less common side effects include sensitivity to light, blurred vision, urinary tract infection, diarrhea, and dizziness. If your erection lasts more than 4 hours seek immediate medical attention, or you risk losing the sexual organ.

Manufacturers of drugs for the treatment of erectile dysfunction also published certain contraindications applicable to sildenafil. For example, Viagra is not prescribed for patients who use nitrates and alpha blockers. For nursing mothers and pregnant women Viagra NZ is not recommended. However, it is unlikely that the effect of the drug can be passed to the child, but even a small chance it may be fatal.

Just like any other drugs, Viagra Austrlaia, Kamagra and sildenafil containing products also have its side effects. Some of the side effects of the drug include drowsiness, irritability, and disorders of the gastrointestinal tract, nausea, disorders of sleep and some of hormonal imbalance.
