When reading about Cialis online (also known as Cialis Tadalafil) we've tried to explain how this prescription drug works in plain English. Our Cialis online section will explain more about PDE5 inhibitors, but remember there is far more chemical information available than we're giving you.
Firstly, Tadalafil is exactly the same drug - this is it's chemical name - Cialis is the brand that they have chosen to market it by. This drug belongs to a group called PDE5 inhibitors and comes in tablet form that can be prescribed in two strengths. It is NOT an aphrodisiac as requires sexual stimulation to work.
Filling the penis with blood causes an erection of the penis. For this to happen there is a series of chemical reactions that occur when the man is sexually stimulated that direct the blood vessels accordingly. The blood vessels allowing blood into the penis increase in size and the blood vessels taking blood away decrease in size thus allowing the erection to be maintained. There is a chemical released after sexual activity that causes the opposite effect, allowing the blood to flow out of the penis and the erection to end. Cialis destroys this chemical, allowing for a prolonged engorgement of the penis with blood and a more sustained erection.
Tablets available on prescription, or online, are to be swallowed whole prior to sexual activity. The amount of time it will take to work varies from person to person, but at least 50% of users find that within 30mins of taken the tablet that can achieve an erection if sexually stimulated. The effects of the medication maybe experienced for up to 36 hours to allow for a period of responsiveness and to provide a period of flexibility during which they can they take the tablet. It can be taken with or without food, and small amounts of alcohol will not affect it's ability to work. However alcohol may generally impede an erection and should be avoided in excess.
If you plan to buy some, which is available from pharmacists online in the UK, then it is important not to exceed the stated dose, as this will not improve is efficacy but may increase the side effects. When taken at the recommend dose clinical trials have proven the side effects, which may include dizziness and indigestion, to be mild and transient. However it should not be taken in conjunction with other medicines containing nitrates, and patients should inform their doctor if they plan to use it in conjunction with other medicines. You should also note that it is only provided on prescription and companies who supply the drug without a prescription are doing so illegally.
