Erectile Dysfunction (ED) is a common sexual condition, with 51% of respondents reporting ED in a population-based study conducted in Singapore. Fortunately, ED is a manageable condition, and Cialis is an the Food and Drug Administration (FDA)-approved treatment trusted globally to treat it. It contains Tadalafil, which is a Phosphodiesterase Type 5 (PDE5) inhibitor that successfully manages erectile issues for better sexual performance.
It is widely known as the weekend pill as it provides long-lasting effects that allow more flexibility and spontaneity in sexual relationships. Due to its popularity, many users also look to buy Cialis online or explore generic Cialis options for convenience and affordability. This article explains the working mechanism of Cialis, including dosage recommendations, potential side effects, and where to buy Cialis safely in Singapore.
Cialis and its working mechanism
The FDA approved Cialis in 2003 for treating ED and enhancing the body’s ability to achieve an erection when sexually stimulated. Its effect can last up to 36 hours, allowing flexibility and spontaneity to enjoy sexual activity without the pressure of strict timing. Additionally, it was approved for the treatment of Benign Prostatic Hyperplasia (BPH) in 2011.
It functions by blocking the PDE-5 enzyme, thereby preventing the breakdown of cyclic Guanosine Monophosphate (cGMP). In turn, cGMP promotes the relaxation of smooth muscles in the penis, enabling increased blood circulation. This further leads to long-lasting and firm erections. On the other hand, for BPH, it functions similarly by relaxing the muscles in the prostate and bladder, thereby improving urinary flow and easing symptoms such as frequent urination or difficulty passing urine.

Also, take the tablet at least 30 minutes before engaging in intimate activity. Below are the general guidelines for Cialis dosage:
- As-needed use: Generally, 10 mg is recommended before sexual activity. The doctor can adjust the dose to 20 mg or lower depending on effectiveness and tolerance.
- Daily use: For spontaneous activity, a lower dose, typically 2.5 mg or 5 mg, is recommended for daily use.
