ضعف الانتصاب, known as erectile dysfunction, affects a man’s ability to maintain an erection. Medications like Viagra and Cialis differ in duration of action. Viagra acts for about four hours, while Cialis may last up to 36 hours. Both drugs function by increasing blood flow to the penis, yet Cialis allows for more spontaneity. For effective use, consult a healthcare professional or a trusted medical site for guidance tailored to individual needs and health conditions.
