What's the same
Voltaren and Tadalafil 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
Voltaren belongs to Pain Relief Medications while Tadalafil belongs to Erectile Dysfunction (ED). 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
Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen. Tadalafil: The mechanism is identical to original Cialis: tadalafil selectively inhibits PDE5 in penile and vascular smooth muscle, allowing cyclic GMP produced during sexual arousal to accumulate.
When Voltaren is preferred
Voltaren is approved in adults for the treatment of osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, acute musculoskeletal pain, post-surgical pain, primary dysmenorrhoea, acute migraine and ureteric colic.
When Tadalafil is preferred
Generic tadalafil shares the indications of the originator: erectile dysfunction in adult men, lower urinary tract symptoms associated with benign prostatic hyperplasia, and pulmonary arterial hypertension at adapted doses.
