Is Cialis Equal to Viagra – Let’s Break It Down

Introduction

When considering options for treating erectile dysfunction (ED), Cialis (tadalafil) and Viagra (sildenafil) are two of the most recommended medications. But do people really know whether Cialis equal to Viagra? Even though both drugs constitute inhibition of enzyme PDE5, leading to blood flow increase, they stand apart in chemical structure, potency, and the period of time which elapses until their effects wear off. Let’s break it all down.

What Are Cialis and Viagra?

Both Cialis and Viagra can only be issued with a prescription and are designed to combat ED. They fall under a group of medicines called PDE5 inhibitors whose purpose is the enhancement of blood circulation in the penis to facilitate the process of getting and holding an erection.

How Do Cialis and Viagra Work?

Both drugs work by inhibiting PDE5, an enzyme that restricts blood flow in the penis. By blocking this enzyme, Cialis and Viagra allow for increased blood flow, helping men achieve erections when sexually stimulated.

• Cialis® dosages start with 5 mg, 10 mg, or 20 mg.
• Viagra® dosages begins with 25 mg, 50 mg, or 100 mg.
• 20mg of Cialis® produces different effects than 100mg of Viagra®.

• Working time:

  • Cialis®: Takes up to 2 hours to work.

Is Cialis Equal to Viagra – Comparison 

• Cialis takes longer to reach peak effectiveness (about 2 hours) compared to Viagra (about 1 hour). If you need quick results, Viagra may be a better choice.
• Cialis lasts significantly longer (up to 36 hours), while Viagra is effective for only 4 to 6 hours.
• 100mg of Viagra is the highest standard dose, while 20mg of Cialis is also a strong dose. The choice between them depends on how long you want the effects to last.

How Do Cialis® and Viagra® Compare?

• Both Cialis and Viagra are PDE5 inhibitors that improve blood flow to the penis.
• Cialis® is sometimes called the “weekend pill” due to its longer duration of up to 36 hours.
• Viagra® acts faster (30 minutes to 1 hour) but lasts only 4 to 6 hours.
