Description
Cialis, known generically as tadalafil, is a medication primarily used to treat erectile dysfunction (ED) and is also approved for the treatment of benign prostatic hyperplasia (BPH). Cialis enables men to achieve and maintain an erection by increasing blood flow to the penis when sexually stimulated. It is taken orally, and its effects can last for up to 36 hours.
Tadalafil works by selectively inhibiting phosphodiesterase type 5 (PDE5), an enzyme that breaks down cyclic guanosine monophosphate (cGMP), a substance that promotes relaxation of blood vessels in the penis. By blocking PDE5, Cialis enhances the effects of nitric oxide, thereby facilitating increased blood flow that results in an erection.
Side Effects
The common side effects of Cialis may include:
- Headache
- Indigestion
- Back pain
- Flushing
- Nasal congestion
Most side effects are generally mild, but in rare cases, individuals may experience more serious effects, such as sudden vision loss or an erection lasting more than four hours (priapism), which requires immediate medical attention.
Medical Uses
Cialis is primarily prescribed for:
- Erectile Dysfunction: It provides an effective treatment option for men with ED, allowing for improved sexual performance.
- Benign Prostatic Hyperplasia: Tadalafil helps alleviate symptoms such as difficulty urinating and the need to urinate frequently or urgently.
The long duration of action with Cialis allows for more spontaneity in sexual activity compared to other ED medications, making it a preferred choice for many. Ongoing clinical research continues to assess its efficacy and safety in various populations, solidifying its status as a leading treatment option for erectile dysfunction and urinary symptoms associated with BPH.
