Gel - 1%

Durilac contains the active substance diclofenac sodium, which is a non-steroidal anti-inflammatory drug (NSAID). Its action is based in the inhibition of cyclooxygenases, which participate in the biosynthesis of prostaglandins. Prostaglandins have an important role in the process of pain, inflammation and chills. Non - steroidal anti-inflammatory drugs inhibit cyclooxygenases-1 and-2 (COX-1 and-2). Inhibition of COX-1 is associated with gastrointestinal side effects, while the inhibition of COX-2 is associated with anti-inflammatory action.

Diclofenac is rapidly absorbed when it is given in the form of rectal suppositories or intramuscular injection. Diclofenac is also absorbed percutaneously. Approximately 99 % of the drug is bound with the plasma proteins. Diclofenac passes in the synovial fluid and in the breast milk. Its plasmatic half life is 1 – 2 hours. It is excreted in the form of glucuronides and sulphates, mainly through urine (65 %) and bile (35 %).

Durilac is used:

• in musculo-skeletal disorders such as rheumatoid arthritis, osteoarthritis, and ankylosing spondylitis;
• in peri-articular disorders such as bursitis and tendinitis;
• in soft-tissue disorders such as sprains and strains;
• in painful conditions such as renal colic, acute gout, dysmenorrhoea;
• after some surgical procedures.
