Cialis 

What is it?

• Cialis is the brand name for the medicine 

• It belongs to the group of drugs called phosphodiesterase type 5 (PDE5) inhibitors.

• Unlike opioids or sedatives, Cialis is used for sexual health and circulation-related conditions.

How It Works

• Cialis blocks the PDE5 enzyme, which increases levels of cyclic GMP (cGMP) in blood vessels.

• This leads to relaxation of smooth muscles and improved blood flow, especially to the penis.

• It helps men achieve and maintain an erection when sexually stimulated.

Medical Uses (Benefits)

• Erectile Dysfunction (ED): Improves sexual performance in men.

• Benign Prostatic Hyperplasia (BPH): Relieves urinary symptoms caused by an enlarged prostate.

• Pulmonary Arterial Hypertension (PAH): Improves exercise ability by relaxing blood vessels in the lungs (marketed as Adcirca for this use).

Harms & Risks

• Common side effects: headache, flushing, indigestion, nasal congestion, muscle aches.

• Serious risks (rare): sudden vision or hearing loss, prolonged erection (priapism), low blood pressure.

• Drug interactions: dangerous when combined with nitrates (used for chest pain) or certain heart medicines, as it can cause a sharp drop in blood pressure.

• Not addictive like opioids or benzodiazepines, but misuse is possible for performance reasons.

Conclusion

• Cialis  is a widely used and effective treatment for erectile dysfunction, enlarged prostate, and pulmonary hypertension.

• It works by improving blood circulation rather than affecting the brain like opioids or sedatives.

• Safe when prescribed, but should be taken only under medical guidance, especially for people with heart conditions.
