Combining Aspirin 81 mg and Diclofenac Sodium is a major interaction and should generally be avoided without close medical supervision.
Combining diclofenac with low-dose aspirin significantly increases your risk of serious bleeding, especially from the stomach or intestines. This combination should generally be avoided.
Mechanism: Diclofenac, a non-steroidal anti-inflammatory drug (NSAID), inhibits prostaglandin synthesis, which can impair gastric mucosal protection and inhibit platelet aggregation. Aspirin 81 mg, an antiplatelet agent, irreversibly inhibits cyclooxygenase-1 (COX-1), leading to reduced thromboxane A2 production and prolonged platelet inhibition. The concurrent use of these drugs results in additive antiplatelet effects and increased gastrointestinal toxicity.

Prostaglandins sensitize afferent nerves and potentiate the action of bradykinin in induc…
