Diclofenac sodium 75 mg is a widely prescribed medication for managing pain and inflammation associated with various medical conditions. As a nonsteroidal anti-inflammatory drug (NSAID), it works by inhibiting the production of prostaglandins, which are hormone-like substances that cause pain and inflammation in the body. With its potent analgesic and anti-inflammatory properties, diclofenac sodium 75 mg has become a go-to treatment option for many healthcare professionals and patients alike.
The medication is commonly used to treat conditions such as osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and gout. It is also effective in relieving pain from menstrual cramps, headaches, and dental procedures. Diclofenac sodium 75 mg is available in various forms, including tablets, capsules, and injectable solutions, making it a versatile treatment option for different patient needs.
Mechanism of Action and Pharmacokinetics
Diclofenac sodium 75 mg exerts its therapeutic effects by inhibiting the cyclooxygenase (COX) enzymes, which are responsible for converting arachidonic acid into prostaglandins. By blocking these enzymes, diclofenac reduces the production of prostaglandins, thereby decreasing pain and inflammation. The medication is rapidly absorbed into the bloodstream, with peak plasma concentrations reached within 2-4 hours after administration.
The bioavailability of diclofenac sodium 75 mg is approximately 50-60%, with a half-life of 1.2-2 hours. The medication is extensively metabolized in the liver and excreted primarily through the kidneys. Its pharmacokinetic profile allows for twice-daily dosing, making it convenient for patients to manage their pain and inflammation.
Clinical Efficacy and Safety
Numerous clinical trials have demonstrated the efficacy and safety of diclofenac sodium 75 mg in managing pain and inflammation. In a randomized, double-blind study, diclofenac sodium 75 mg was shown to significantly reduce pain intensity and improve functional ability in patients with osteoarthritis. Another study found that diclofenac sodium 75 mg was effective in reducing inflammation and pain in patients with rheumatoid arthritis.
While diclofenac sodium 75 mg is generally well-tolerated, it can cause gastrointestinal side effects, such as nausea, diarrhea, and abdominal pain. More serious adverse reactions, including gastrointestinal bleeding and cardiovascular events, can occur, especially with prolonged use or in patients with pre-existing medical conditions. Healthcare professionals should carefully evaluate the benefits and risks of diclofenac sodium 75 mg for each patient and monitor them closely for potential side effects.
| Adverse Reaction | Frequency (%) |
|---|---|
| Gastrointestinal upset | 10-20 |
| Abdominal pain | 5-10 |
| Diarrhea | 5-10 |
| Nausea | 5-10 |
| Cardiovascular events | 1-5 |
