Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) that is widely used to treat various conditions associated with pain and inflammation. It is available in several forms, including oral tablets, topical gels, and injectable solutions. The primary mechanism of action of diclofenac involves the inhibition of cyclooxygenase (COX) enzymes, which are responsible for the production of prostaglandins, thereby reducing inflammation and pain.
Medical Uses of Diclofenac
Diclofenac is used to treat a range of medical conditions, including osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis. It is also effective in managing acute pain associated with injuries, surgery, and menstrual cramps. Additionally, diclofenac is used to treat migraines and other types of headaches. Its anti-inflammatory properties make it an effective treatment for reducing swelling and pain in the body.
Treatment of Pain and Inflammation
Diclofenac works by blocking the production of prostaglandins, which are hormone-like substances that cause pain and inflammation in the body. By reducing the levels of these substances, diclofenac helps to alleviate pain and inflammation, making it an effective treatment for various conditions. The topical form of diclofenac is particularly useful for treating musculoskeletal pain and inflammation, such as strains and sprains.

|---|---|
| Osteoarthritis | 100-150 mg/day |
| Rheumatoid Arthritis | 150-200 mg/day |

Side Effects and Precautions
While diclofenac is generally well-tolerated, it can cause side effects, such as gastrointestinal upset, nausea, and dizziness. It is crucial to take diclofenac with food to reduce the risk of stomach upset. Patients with a history of peptic ulcers or bleeding disorders should use diclofenac with caution, as it can increase the risk of bleeding. Additionally, diclofenac may interact with other medications, such as blood thinners and diuretics, which can increase the risk of adverse effects.
Contraindications and Warnings
Diclofenac is contraindicated in patients with a history of aspirin allergy or NSAID sensitivity. It should also be used with caution in patients with kidney disease or liver disease, as it can worsen these conditions. Pregnant women should avoid using diclofenac, especially during the third trimester, as it can increase the risk of premature closure of the ductus arteriosus.
