Tadalafil, generically known as Cialis, is a popular erectile dysfunction (ED) medication that is available in various forms such as tablets, capsules, and vials. Cialis has become increasingly popular due to its proven efficacy and rapid onset of action, which is the same effect that comes with using an oral medication like Viagra® for men suffering from erectile dysfunction. This article delves into the various forms of Cialis, including its uses, potential side effects, dosage, and more.
Cialis, which is also known by its generic name tadalafil, is a popular oral ED medication that can be purchased at any pharmacy or online store. This medication is known for its fast onset of action and its effectiveness, making it a popular choice for men seeking treatment for erectile dysfunction.
Cialis is a brand name for tadalafil, which stands forTadalafil. Cialis works by increasing blood flow to the penis, helping men achieve and maintain an erection. Unlike some other erectile dysfunction drugs, Cialis is taken orally, meaning it does not have to be taken daily. It is often taken for as long as 36 hours after it is ingested.
Cialis works by inhibiting an enzyme called phosphodiesterase type 5 (PDE5), which is responsible for breaking down cyclic guanosine monophosphate (cGMP), an important molecule in the body. By blocking PDE5, Cialis helps to relax the muscles in the blood vessels of the penis, allowing increased blood flow and facilitating an erection.
Cialis is a selective PDE5 inhibitor, meaning it only affects the phosphodiesterase type 5 (PDE5) enzyme in the body. By blocking PDE5, Cialis helps to relax cGMP, allowing cGMP to accumulate in the penis, leading to an erection. Cialis also relaxes smooth muscles in the blood vessels of the penis, allowing increased blood flow and facilitating an erection.
It’s important to note that Cialis does not work against erectile dysfunction. It only works when Cialis is taken, but the dosage and duration of Cialis can vary. Always follow your healthcare provider’s instructions when taking Cialis.
The recommended starting dose of Cialis is 50 mg, taken as needed, approximately 30 minutes before sexual activity. It can be adjusted based on individual response and tolerability, as well as the severity of the underlying condition. It is important to follow the prescribed dosage regimen to ensure optimal results.
For men with moderate or severe erectile dysfunction, the recommended starting dose is 10 mg, taken as needed, approximately two hours before sexual activity. The dosage can be increased to 20 mg or decreased to 5 mg based on efficacy and tolerability.
For men with mild to moderate erectile dysfunction, the recommended starting dose is 5 mg, taken as needed, approximately 15 to 30 minutes before sexual activity. The recommended dosage may be increased to 20 mg if appropriate. It is important to note that Cialis should not be taken more than once a day.
For men with frequent or severe erectile dysfunction, the recommended starting dose is 10 mg, taken as needed, approximately 30 to 60 minutes before sexual activity. The dosage may be increased to 20 mg if appropriate. It is important to follow the prescribed dosage instructions to maximize the effectiveness of Cialis in managing erectile dysfunction.
While Cialis is generally well-tolerated, some men may experience side effects. Common side effects of Cialis include headaches, flushing, nasal congestion, and indigestion. Less common but more serious side effects are vision changes, such as a sudden decrease or loss of vision in one or both eyes. If any of these side effects persist or worsen, it is crucial to seek medical help right away.
For men with severe erectile dysfunction or priapism (a painful erection lasting more than four hours), it is important to seek medical help. Priapism can be life-threatening and requires immediate medical attention. If you experience any of these side effects, it is crucial to seek prompt medical treatment.
AstraZeneca’s recent patent expiry on its new erectile dysfunction drug, Cialis, is a reminder that generic competition to the drug will likely keep the drug from being a first-line treatment for ED.
The patent expiration of Cialis will probably be a boon for consumers, because, as the patent for the drug expires, the generic manufacturer will have to come up with a new way to sell its product without having to pay a premium to the original. The patent exclusivity for Cialis is expected to hit $1 billion by 2022, according to recent data from IMS Health.
The market for ED drugs is enormous. Of the 8.4 billion prescriptions filled in 2024, about 1.1 billion were filled in the US alone. But, as many as 1.5 billion are written off in the first nine months of 2025, according to IMS. That’s because the patent for Cialis expires, so it isn’t just about getting a new product to compete with the little blue pill.
But the expiry of the patent has been a significant blow to AstraZeneca. After the patent exclusivity expired, generic competition to the drug began to shift to the other drug. This led to a rise in generic competition, especially as other drugs like Viagra and Cialis were now available at lower prices.
This article discusses a new drug for erectile dysfunction that may be worth a try in the US. It is called tadalafil, which is a type of drug that is used to treat high blood pressure.
The article, which appeared in, will cover how the drug is developed, uses, and potential side effects of the drug.
The article also explains how a clinical trial that looked at the use of tadalafil for ED would be published. In the paper, we will talk about the results of that trial, and why it wasn’t published.

The British Medical Journal published an article on January 20, 2006 (2), in theBritish Medical Journal(BMJ) in which it concluded that Cialis, another erectile dysfunction drug, is ‘not safe for people of any age’ and ‘unapproved’ to be sold in the UK.
It is now the only drug licensed to treat erectile dysfunction, and the only drug to treat benign prostatic hyperplasia, and the only drug to reduce the risk of CVD (and also the risk of heart attacks and strokes) in the general population, with a small but significant increase in the number of people who experience a reduced or ‘normal’ erection when it is not ‘erectioned’.
It’s also now the only drug approved by the Food and Drug Administration (FDA) to treat benign prostatic hyperplasia, with the most recently approved Cialis (tadalafil) being a prescription medicine for use in the UK. Cialis was the first approved drug for the treatment of erectile dysfunction, and the first drug to be approved to treat benign prostatic hyperplasia.
Cialis was developed by Eli Lilly (Lilly) and is now available on the NHS, and is available in pharmacies as well as in the UK.
The NHS website states that ‘the first Cialis tablets (10 mg and 20 mg) will be available on the NHS starting on April 26, 2008.
Cialis (tadalafil) is a PDE-5 inhibitor. The drug relaxes smooth muscle tissue and increases blood flow to the penis, allowing men to achieve and maintain an erection. It is the only drug that has been shown to be safe and effective in men aged 18 years and older.
In a study of over 2,000 men, men who took Cialis 20 mg and 10 mg, once a day, were much more likely to achieve a firm and lasting erection than those who took a placebo. The difference was small but still significant, and the authors noted that ‘the men who took the placebo were also more likely to have a firm and lasting erection than those who took the placebo. The men who took the Cialis treatment were more likely to have a reduced or ‘normal’ erection when they were taking the placebo’.
The study was conducted in two phases. The first phase was an open label phase, and the second phase was a long-term extension phase. Both phases were designed to be compared with a placebo, but this was a small and short-term extension phase. The primary outcome measures used in this study were the erectile function at the beginning of the second and third phase, as well as the duration of the erection, and the frequency of intercourse.
The researchers found that men who took a placebo had a significantly lower frequency of intercourse than those who took a placebo. They also noted that intercourse lasted around 6 hours, with the longest duration of intercourse of 24 hours, followed by a ‘low’ frequency of intercourse and intercourse lasting around 3 hours.
Both men also had a significantly reduced frequency of intercourse, compared to men who took the placebo. They also found that the duration of intercourse lasted around 8 hours, with the longest duration of intercourse of 8 hours.
