Viagra is used to treat erectile disfunction in men. Erectile dysfunction is the inability for men to achieve or maintain an erect penis during sexual activity. What may be news to some is that Viagra or sildenafil primary use was actually discovered by accident. The drug was originally intended to treat hypertension and angina pectoris, more commonly known as chest pain. Researchers soon found out from their clinical trials that the drug was much more effective in producing erections in men than in reducing chest pain. Approval of the drug by the FDA was quick and sales soon skyrocketed.
How it works
The drug works by relaxing muscles in the walls of blood vessels which in turn stimulates and increases blood flow to particular areas of the body. Viagra does not work without sexual stimulation as it’s catalyst. When a man is aroused, muscles in the penis will become relaxed to allow for the increased blood flow to the penis, resulting in an engorged erect penis.
Who should take Viagra
Viagra is taken orally, the most common dosage of Viagra is a 25mg pill or 50 mg pill. Viagra is intended for men of older age who are experiencing a low sex drive or the inability to get or maintain an erection, but it has increasingly become a drug of choice for younger men who seek the drug for recreational use. Before taking Viagra it is advised that you cross reference any other drugs that you may be taking to ensure there are no adverse reactions from mixing those drugs with the use of Viagra. It is advised that if you use nitrates you should avoid Viagra completely due to potential fatal consequences.
The most common side effects in men are headaches, visual impairment and congestion. Other more serious side effects can be upset stomach, indigestion, chest pain, blurry or loss of vision, burning sensation while urinating, deafness or hearing loss, fever or chills, trouble breathing, shakiness, restless sleep, numbness of the hands, lower back pain, eye pain, convulsions, anxiety and bleeding of the eye.
The popularity of the drug has made it widely available. In the past a prescription was required from a medical professional before you could acquire the drug. Although a prescription is still required to buy the drug from a traditional brick and mortar pharmacy, today Viagra can be ordered online, quickly and with complete confidentiality. A quick search for “Viagra in South Africa” in any search engine will yield thousands of results with retailers not only selling the drug but many generic versions as well.

Levitra is used to treat erectile dysfunction, and costs only $2.00 per pill. Levitra is FDA approved and is in class PDE5 inhibitor. Levitra is in these class because of how the drug works. During erectile dysfunction, a chemical called PDE5 prevents an enzyme called cGMP, and the nerves do not react to stimulation as they should. Levitra decreases the amount of PDE5, making it much easier to achieve an erection. Unlike Viagra, Levitra uses Vardenafil to stimulate blood flow and help with getting an erection. This chemical also helps men who are having problems with premature ejaculation, making sex last much longer. It works close to 80% of the time. Levitra is considered by far the cheapest route in solving erectile dysfunction problems. Levitra works better with food or alcohol than its competitor Viagra.

Viagra can be slowed down or be made less effective in the presence of alcohol or food, but Levitra has less of a problem working in these circumstances. The only foods that affect Levitra are those that are high in fat. Levitra has very little after effects, making it better to use than other drugs which have many known side effects. If any side effects occur, you should call or visit a doctor. Many people mistakenly believe that drugs such as Levitra will increase desire, but it is only meant to increase blood flow. Levitra is available in doses of 2.5,5,10, or 20 mg. It should only be consumed once a day, and it should be taken at least an hour before you want to have sex. It takes as little as 30 minutes to activate and work its way through your system. You have to be aroused for Levitra to work, it will not work otherwise. If you take Levitra and it doesn’t work the first time, you may want to talk to your doctor about increasing your dosage. Implementing a higher dosage may increase your chance of achieving erection. Erectile dysfunction can be caused by stress, and can lead to further stress down the road if you are having trouble having sexual relations with your partner. Levitra is meant to help relieve some of this stress by solving this problem. However, Levitra cannot cure bigger relationship problems and should not be treated as a cure all. Stress from emotional issues between you and your partner will still be there. Levitra does not require a prescription. As well as increasing blood flow, Levitra is a known muscle relaxant.
Side effects could include sudden lowered blood pressure, causing dizziness, fainting, stroke, or heart attack. Less significant side effects include headache, runny nose, stomach and back irritation. Anyone who takes nitrates or riociguat should avoid Levitra, as well as anyone with heart problems. Talk to your doctor before combing Levitra with other medications. Levitra cannot stop the spread of STDs. You should tell your doctor you are talking Levitra. Men older than 65 may have to take a lower dosage. Levitra should not cause an erection longer than four to five hours, nor should you have changes in your vision. You should go to the emergency room immediately if either occur.

Cialis is a medication that contains the drug known as Tadalafil in its formula, which is a phosphodiesterase type 5 inhibitor (PDE5). Pharmaceutical experts have been trying to obtain a formula that would allow a longer duration of biochemical effects compared to other PDE5 inhibitors. This is how Cialis was elaborated as an effective remedy for men with ED. It is different when compared to other PDE5 inhibitors, such as vardenafil or sildenafil, in that it is quickly absorbed after being orally administered, and the effects last anywhere between 36 hours and 48 hours after ingestion. Tadalafil, which is the active ingredient contained in Cialis, works by addressing the physiologic deficiencies that may be experienced by men who suffer from a poor erectile response to sexual stimulation. Cialis (Tadalafil) operates by blocking the activity of phosphodiesterase type 5, which allows for a better dilation of the specialized blood vessels inside the penis, contributing to an improved erection for a high-quality sexual performance.

How does Cialis (Tadalafil) work to achieve the correction of the poor erectile response exhibited by some men who have the symptoms of erectile dysfunction?
Sexual stimulation is followed by a nerve signal transmitted from the brain to the nerve endings located in the cavernous structures of the penis, which results in the release of a messenger, which is NO or nitric oxide. This messenger activates a specific enzyme that is responsible for producing cGMP, a biological component that has the property to dilate the blood vessels in the penis directly. The end result is a substantial increase in the blood flow, which allows the filling of the penis cavernous bodies with blood, resulting in a normal erection. However, there is also another enzyme that is responsible for terminating the effects of cGMP, and it is called PDE5. It is mostly located in the penis, but it may also be found in the lungs, which also explains the utility of Tadalafil in the treatment of pulmonary hypertension. When the amounts of cGMP are low, the erection may be weak and deficient, which may translate in the symptoms of ED. Cialis is rapidly absorbed after oral ingestion, and starts to inhibit the PDE5 enzyme. It results in a significant accumulation of cGMP, restores the healthy potential of a man to achieve a solid erection and rejuvenates his sexual life. The effects of Cialis (Tadalafil) may last for up to two days, which is why it is sometimes referred to as “the weekend pill”. Tadalafil, the main ingredient, has the longest duration of action compared to other PDE5 inhibitors, which makes it a favorite among erectile dysfunction sufferers. If you experience mild and temporary side effects after Cialis intake, such as nausea, nasal congestion, headaches or abdominal disturbance, don’t hesitate to address these complaints by consulting with your physician.
