Cialis (tadalafil) and Viagra (sildenafil) are phosphodiesterase-5 (PDE5) inhibitors used for treating impotence (erectile dysfunction, or ED).

Viagra is also approved for the treatment of pulmonary arterial hypertension. Cialis was originally developed to treat erectile dysfunction by inhibiting PDE5, which is involved in the erection process by relaxing smooth muscle tissue in the penis, allowing blood to flow into the corpus cavernosum. The corpus cavernosum houses the erectile tissue of the penis, and when blood flow is increased in this area, an erection results.

Cialis has a longer half-life than Viagra, so it can remain in your system for up to 36 hours. This means that you can take it less frequently than Viagra, which needs to be taken about every four hours.

The downside of this is that if you take Cialis too often, you may develop tolerance to its effects and it may not work as well. Another difference between Cialis and Viagra is that Cialis can be taken with or without food while Viagra should be taken on an empty stomach.

So does Cialis work as well as Viagra? The answer is maybe. It depends on what you’re looking for and how often you need to take it. If you want something that will last longer and don’t mind taking it more frequently, then Cialis might work better for you. If you want something that kicks in faster and only need it occasionally, then Viagra might be a better choice.

Cialis (tadalafil) and Viagra (sildenafil) are oral drugs that are used to treat erectile dysfunction (ED). They are in a class of drugs called phosphodiesterase-5 (PDE5) inhibitors. PDE5 inhibitors work by relaxing muscles and increasing blood flow to specific areas of the body.

Cialis and Viagra are similar drugs. They both can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor’s instructions.

Both medications are generally safe and well tolerated. However, there are some differences between them.

Cialis lasts longer than Viagra does: about 18 hours compared to 4-6 hours for Viagra . This means that you could take Cialis the night before sex, rather than having to take it an hour before sex like with Viagra . This may make it more convenient for some people since they do not have to plan their sexual activity around taking a pill an hour beforehand. However, it can also make planning sex more difficult since you need to allow enough time for the drug to work – which may not always be convenient if spontaneous sex is on the cards!

These side effects include changes in color vision (such as having a blue color tinge) and increased sensitivity to light. These side effects usually go away after a few hours. In rare cases, permanent vision loss has been reported with Cialis use – more so than with Viagra . It is important that you see an ophthalmologist immediately if you experience any changes in your vision while taking either medication . If you have heart disease or low blood pressure , be sure to tell your doctor before taking either medication . Also let your doctor know if you have ever had any type of heart condition known as “ Long QT Syndrome .” You should not take these medications if you have certain medical conditions or are taking certain other medications because serious interactions can occur . Be sure to talk with your healthcare provider about all of your options for treating ED before deciding which one is right for you

It is a common question asked by many men who are suffering from erectile dysfunction. Both Viagra and Cialis are effective treatments for ED, but they work in different ways. Viagra works by inhibiting the enzyme that breaks down cGMP, allowing cGMP to accumulate and produce an erection. Cialis works by inhibiting the PDE5 enzyme, which allows more cGMP to be produced, leading to improved erections. So, while both drugs work in similar ways, they have different mechanisms of action.

Viagra was released in 1998 and was the first oral treatment for ED approved by the FDA. It quickly became a blockbuster drug, with sales reaching $1 billion within three years of its release. Cialis was approved in 2003 and has since become one of the most popular ED drugs on the market. While Viagra remains the best-known treatment for ED, Cialis has several advantages over Viagra that make it a popular choice among men who are looking for an effective treatment option.

One advantage of Cialis over Viagra is that it has a much longer half-life than Viagra – meaning that it stays active in your body for much longer than Viagra does. While Viagra typically lasts for four hours, Cialis can last for up to 36 hours – giving you a much larger window of opportunity to get and keep an erection when you need it most. Additionally, because Cialis is available in lower doses than Viagra (5mg, 10mg, 20mg), it can be taken as needed – unlike Viagra which must be taken about an hour before sexual activity is anticipated in order to be effective. This means that you don’t have to plan your sex life around taking a pill – which can be frustrating and inconvenient – but can instead take Cialis as needed when you want to have sex without having to worry about whether or not the drug will still be active in your system.

Another advantage of Cialis over Viagra is that it tends to have fewer side effects than Viagra does because it doesn’t affect other parts of your body besides your PDE5 enzymes (which are responsible for erections). The most common side effects associated with Cialis include headache, indigestion/heartburn, stuffy nose/sinus congestion/runny nose/sneezing/nausea/dizziness or lightheadedness (these side effects usually go away after a few hours). In contrast, becauseViagratargetsthe entire body (not just PDE5 enzymes), its list of potential side effects is much longer and includes vision changes such as blue tinted vision or increased sensitivity to light; hearing changes such as ringing ears; digestive issues such as diarrhea or constipation; flushing; skin rash; muscle pain or tenderness; headache; stuffy nose/sinus congestion/runny nose; upset stomach/nausea/. Because CIALiS prescribe in the lower doses (5mg,, and 20mg), these potential side effects tend to be common place and not severe compared to those seen with higher doses of Viagra that are usually prescribed(25mg,, 50mg,, 100mg or 200mg or higher).

Consequently, patients who are using CIALIS for ED have a much lower chance of developing a side of their therapy compared to those using VIAGRA– making symptom management much more convenient and effective for the men who desire to pursuit treatment for their own erectile dysfunction. Additionally, VIAGRA works best when it is used on an empty stomach or after eating a light meal,however, CIALIS can be used with food or without it - making sure that men who have issues with food restrictions or sensitivities do not have to worry about their therapy inhibiting their ability to eat what they want when they need to in order to remain healthy. All in all these advantages make CIALIS a popular choice for many men who desire an effective treatment for their ED that is much more convenient than VIAGRA treatment can be.
