Key differences
Voltaren belongs to Pain Relief Medications while Toprol XL 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
Voltaren: Diclofenac reversibly inhibits cyclooxygenase enzymes COX-1 and COX-2, with somewhat greater selectivity for COX-2 than ibuprofen and naproxen. Toprol XL: Metoprolol selectively blocks beta-1 adrenergic receptors in the heart, reducing heart rate, contractility and atrioventricular conduction velocity, and lowering myocardial oxygen demand.
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 Toprol XL is preferred
Toprol XL is approved in adults for the treatment of hypertension, chronic stable angina pectoris and stable, symptomatic heart failure with reduced ejection fraction (NYHA class II to IV), in addition to standard therapy.
