Aurogra 100 and Cialis are both medications used to treat erectile dysfunction (ED) in men, but they contain different active ingredients and work in distinct ways:

1. 
   

   Aurogra 100 (Sildenafil Citrate):

   
   
   • Aurogra 100 contains sildenafil citrate, which is a phosphodiesterase type 5 (PDE5) inhibitor. It works by increasing blood flow to the penis during sexual stimulation, helping men achieve and maintain an erection.
   
   
   • Aurogra 100 typically starts working within 30 to 60 minutes after ingestion, and its effects may last for up to four hours.
   
   
   • It is usually taken on an as-needed basis, about one hour before anticipated sexual activity.
   
   


2. 
   

   Cialis (Tadalafil):

   
   
   • Cialis contains tadalafil, also a phosphodiesterase type 5 (PDE5) inhibitor. Like sildenafil, it works by increasing blood flow to the penis during sexual stimulation to facilitate erections.
   
   
   • One significant difference is that Cialis has a longer duration of action compared to Aurogra and other sildenafil-based medications. Cialis can provide the ability to achieve an erection for up to 36 hours after taking the medication. This has earned it the nickname "the weekend pill."
   
   
   • Cialis can be taken on an as-needed basis (typically 30 minutes to one hour before sexual activity) or as a daily low-dose tablet, which allows for spontaneity in sexual activity.
