Key differences
Propecia belongs to Male and Female Pattern Hair Loss while Voltaren belongs to Pain Relief 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
Propecia: DHT, produced from testosterone by 5-alpha-reductase, drives miniaturisation of scalp hair follicles in genetically susceptible men, gradually shortening anagen growth phases until follicles produce only fine vellus hair… Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen.
When Propecia is preferred

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.
