Cialis, containing tadalafil, works by increasing blood flow to the penis. This happens through the inhibition of a specific enzyme called phosphodiesterase-5 (PDE5). PDE5 normally breaks down a chemical messenger called cyclic guanosine monophosphate (cGMP). cGMP relaxes smooth muscles in the penis, allowing for increased blood flow.
How Tadalafil Improves Erectile Function
By blocking PDE5, tadalafil allows cGMP levels to remain elevated for a longer period. This sustained increase in cGMP leads to prolonged smooth muscle relaxation, facilitating easier blood flow into the penis and resulting in improved erectile function. The effect is noticeable, lasting significantly longer than many other medications in its class.
Factors Influencing Cialis’s Effectiveness
Several factors can influence how well Cialis works. These include individual differences in metabolism, overall health, and the presence of other medical conditions. Always consult your doctor to discuss any potential interactions with other medications you’re taking. Your doctor can help determine the appropriate dosage and assess your suitability for Cialis.
Important Note Regarding Dosage and Side Effects
Dosage varies based on individual needs and response. Common side effects are usually mild and temporary, including headache, flushing, and nasal congestion. Severe side effects are rare, but you should seek immediate medical attention if you experience sudden vision loss, chest pain, or a prolonged, painful erection (priapism).
