Uses of Alkanon 500mg Tablet

• Pain Relief

How does Alkanon 500mg Tablet work?

Nabumetone works by blocking the effects of COX enzymes. This prevents prostaglandin synthesis (prostaglandins elevate body temperature and make nerve endings more sensitive to pain transmission).

Osteoarthritis:

Osteoarthritis is a joint disease characterized by the breakdown of the protective cartilage covering the ends of the joints. In this condition, the absence of protective cartilage causes the joints to come together, resulting in friction between them. This leads to symptoms such as pain, stiffness, inflammation, and tenderness. Individuals with osteoarthritis may experience discomfort and limited mobility due to the rubbing of joints against each other.

Rheumatoid Arthritis:

Rheumatoid arthritis is an autoimmune disease where the body's immune system mistakenly attacks its tissues, specifically the joints. This immune system activity causes joint pain and damage over time. Symptoms of rheumatoid arthritis encompass pain, swelling, stiffness, deformities, and loss of joint function. Unlike osteoarthritis, rheumatoid arthritis involves an inflammatory process driven by the immune system, leading to more widespread and systemic effects on the body. Early diagnosis and appropriate management are crucial in mitigating the impact of rheumatoid arthritis on joint health.

Pharmacology:

Inhibits synthesis of prostaglandins in body tissues by inhibiting at least 2 cyclooxygenase (COX) isoenzymes, COX-1 and COX-2. May inhibit chemotaxis, alter lymphocyte activity, decrease proinflammatory cytokine activity, and inhibit neutrophil aggregation; these effects may contribute to anti-inflammatory activity.
