Diclofenac sodium extended-release (EC) 75 mg tablets have emerged as a widely prescribed medication for managing various types of pain, including inflammatory and degenerative conditions. As a nonsteroidal anti-inflammatory drug (NSAID), diclofenac works by inhibiting the production of prostaglandins, which are hormone-like substances that cause pain, inflammation, and fever in the body.
Patients suffering from conditions like osteoarthritis, rheumatoid arthritis, and ankylosing spondylitis often experience significant pain and discomfort. In such cases, diclofenac sod EC 75 mg can provide effective relief, enabling individuals to carry out their daily activities with greater ease. The extended-release formulation allows for a gradual release of the active ingredient, providing sustained pain relief over an extended period.
Mechanism of Action and Pharmacokinetics
Diclofenac sodium exerts its therapeutic effects by selectively inhibiting the cyclooxygenase-2 (COX-2) enzyme, which is primarily responsible for the production of prostaglandins. By blocking this enzyme, diclofenac reduces the synthesis of prostaglandins, thereby decreasing inflammation and pain. The extended-release formulation of diclofenac sod EC 75 mg is designed to provide a steady plasma concentration of the drug, maintaining its therapeutic effects over a prolonged period.
Following oral administration, diclofenac is rapidly absorbed, with peak plasma concentrations reached within 2-4 hours. The bioavailability of diclofenac is approximately 50-60%, and it is extensively metabolized in the liver. The elimination half-life of diclofenac ranges from 1.5 to 2 hours, necessitating twice-daily dosing for immediate-release formulations. However, the extended-release formulation of diclofenac sod EC 75 mg allows for once-daily dosing, enhancing patient compliance.
Clinical Efficacy in Pain Management
Numerous clinical trials have demonstrated the efficacy of diclofenac sod EC 75 mg in managing various types of pain. In patients with osteoarthritis, diclofenac has been shown to significantly reduce pain intensity and improve functional ability. Similarly, in patients with rheumatoid arthritis, diclofenac has been found to decrease disease activity and improve quality of life.
A randomized, double-blind study published in the Journal of Clinical Rheumatology found that diclofenac sod EC 75 mg significantly reduced pain intensity and improved functional ability in patients with osteoarthritis, compared to placebo. Another study published in the European Journal of Rheumatology demonstrated the efficacy of diclofenac in reducing disease activity and improving quality of life in patients with rheumatoid arthritis.

Potential Side Effects and Precautions
While diclofenac sod EC 75 mg can be an effective pain relief solution, it is essential to be aware of potential side effects and precautions. Common side effects include gastrointestinal disturbances, such as nausea, vomiting, and diarrhea, as well as dizziness, headache, and fatigue.
Serious side effects, although rare, can include gastrointestinal bleeding, renal impairment, and cardiovascular events. Patients with a history of gastrointestinal disease, renal impairment, or cardiovascular disease should be closely monitored while taking diclofenac. It is also essential to inform patients about the potential risks and benefits of diclofenac and to carefully weigh these factors when prescribing the medication.
Conclusion and Future Directions
In conclusion, diclofenac sod EC 75 mg is an effective pain relief solution for managing various types of pain, including inflammatory and degenerative conditions. The extended-release formulation provides sustained pain relief over an extended period, enhancing patient compliance. However, it is essential to be aware of potential side effects and precautions, particularly in patients with a history of gastrointestinal disease, renal impairment, or cardiovascular disease.
Future research directions may focus on optimizing the dosing regimen and exploring the potential benefits of combination therapy with other pain relief medications. Additionally, further studies are needed to fully elucidate the mechanisms of action of diclofenac and to identify potential biomarkers for predicting treatment response.
