General Information On Cialis
Cialis (generic name: Tadalafil) is an oral medication indicated for treating sexual problems in men like impotence and erectile dysfunction. Tadalfil belongs to the category of PDE5 inhibitors and works by relaxing the blood vessels in the penis and increasing blood flow to its muscular tissues. In this way, erection is achieved and maintained as long as the effects of the drug last. You can buy Cialis oral tablets in 2.5mg, 5mg, 10mg and 20mg strengths, and a higher dose of the drug can also be used for treating pulmonary artery hypertension.
Side Effects for Cialis
Headache, back pain, stomach upset, muscle pain, flushing, nasal stuffiness, pain in the legs or arms, dizziness, and vision changes are some commonly experienced side effects of Cialis. Sometimes, patients with certain health problems may also develop NAION, a sudden loss of sight in both the eyes or one eye. As sexual activity can put extra stress on your heart, especially if you have heart disease or are over 50 years of age, you should seek medical help if you experience chest pain, fainting, or severe dizziness during sex. If you have a prolonged and painful erection for 4 hours or longer, you should stop taking Cialis and inform your doctor about your condition. If you experience sudden hearing problem or ringing in your ears, you should stop using Cialis and consult your doctor.
Patients with diabetes, heart disease, crowded disk, high blood pressure, high cholesterol, and those who are over 50 years of age and smoke may suffer from sudden loss of sight in both or one eye/s while on Cialis treatment. In that case, you should stop using the drug immediately and seek medical help, as your doctor will either advise you to stop the medicine or decrease its dosage. Cialis does not provide protection against diseases like HIV, syphilis, gonorrhea, or hepatitis B, and so, you should practice safe sex by using a barrier form of contraception like condoms. Your doctor will not recommend you to buy Cialis if you are suffering from a penis condition, sickle cell anemia, kidney or liver disease, eye problem, blood cancer, active stomach ulcers, bleeding disorder, heart problem, low or high blood pressure, or have suffered a stroke. As the drug may make you dizzy, you should limit alcohol intake and not perform any activities that require complete alertness, such as driving a vehicle or operating a machine. Cialis cannot be used by women and children.
Men are advised to take Cialis 10mg before sex, only once a day. If your doctor has advised you to take the drug every day, he will probably ask you to take Cialis 2.5mg to 5mg at the same time every day irrespective of whether you have an active sex life or not.
Cialis should not be taken with nitrates like nitroglycerin, nitroprusside, or recreational drugs or poppers containing amyl/butyl nitrite. Before using Cialis, you should inform your doctor if you are already taking alpha-blocker medicines like doxazosin and terazosin, drugs affecting liver enzymes like rifamycin, and drugs for impotence and high blood pressure. You should not take Cialis with any other medicine that contains Tadalfil or any other drug used for treating pulmonary hypertension or erectile dysfunction, such as vardenafil or sildenafil.

What is a "Generic" medication/drug?
Generic drugs are medications that have comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo testing to ensure that they are similar to their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with the comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain the same active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must have a comparable strength and dosage as the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically equivalent. They may look different, and be called something different.
How are Generic drugs tested to ensure quality and efficacy?
Generally speaking, the two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
