Cialis and Crestor are used in very different patients, and the points in common are limited. The main shared element is that both meet regulatory standards for efficacy and safety and benefit from pharmacist oversight.
Key differences
Cialis belongs to Erectile Dysfunction (ED) while Crestor belongs to Cardiovascular Medications. Indications, mechanisms and target populations differ. The comparison is most useful when a clinician has mentioned both medications and the patient wants to understand where each fits.
Mechanism and action
Cialis: During sexual stimulation, nitric oxide is released in the corpus cavernosum and activates an enzyme that produces cyclic GMP. Crestor: Rosuvastatin competitively inhibits HMG-CoA reductase, the rate-limiting enzyme in hepatic cholesterol synthesis.
When Cialis is preferred
Cialis is indicated in adult men for the treatment of erectile dysfunction.
When Crestor is preferred
Crestor is approved in adults for the treatment of primary hypercholesterolaemia and mixed dyslipidaemia, for the prevention of cardiovascular events in patients at elevated risk and for the secondary prevention of cardiovascular events.
Frequently asked questions
Is Cialis or Crestor better? ▾

Can I switch from Cialis to Crestor? ▾
Switching between Cialis and Crestor is rarely an appropriate decision since they belong to different classes and treat different conditions. The real question is usually whether the diagnosis calls for one medication or the other — which the prescriber resolves.
Do Cialis and Crestor have the same side effects? ▾
No — they belong to different classes and have distinct side-effect profiles. Each medication has its own prescribing information.
