Cialis treats erectile dysfunction by increasing blood flow to the penis. It achieves this by inhibiting a specific enzyme, phosphodiesterase-5 (PDE5).
PDE5 normally breaks down cyclic guanosine monophosphate (cGMP), a molecule crucial for penile erection. By blocking PDE5, Cialis allows cGMP to persist, resulting in relaxed penile muscles and increased blood flow. This facilitates achieving and maintaining an erection.
The medication’s effect isn’t immediate; it typically takes 30-60 minutes to become fully active. Importantly, sexual stimulation remains necessary; Cialis doesn’t cause erections without sexual arousal.
Cialis comes in two main forms: daily and as-needed. The daily dose maintains a consistent level of the drug in your system, allowing for spontaneous sexual activity. The as-needed dose is taken approximately 30 minutes before anticipated sexual activity.
Consult your doctor before using Cialis to discuss potential side effects and interactions with other medications. They can help determine the appropriate dosage and ensure it’s a safe and suitable treatment option for you.
