Pharmacological class: Non-steroidal Anti-inflammatory and analgesic
Diclofenac is a non-steroidal anti-inflammatory (NSAID) and analgesic preparation designed for external application. Diclofenac is a potent non-steroidal anti-inflammatory drug with analgesic and antipyretic properties. It is also has uricosuric effect. Diclofenac inhibits cyclo-oxygenase activity with a reduction of production of prostaglandins in the tissue.
Linseed oil inhibits PGE2, leukotriene, histamine and bradykinin induces inflammation. The oil also inhibited arachidonic acid-induced inflammation, suggesting its capacity to inhibit both cyclooxygenase and lipooxygenase pathway of arachidonate metabolism.
Methyl Salicylate is applied topically as counter irritants for relief of pain associated with lumbago, sciatica, and rheumatic conditions.
Menthol, after topical application, causes a feeling of coolness due to stimulation of cold’receptors by inhibiting ca++ currents of neuronal membranes. It may also yield analgesic properties via kappa-opioid receptors agonism.
When Diclofenac Gel is applied locally the active substances are absorbed through the skin, determined by reference to the urinary excretion of Diclofenac and its hydroxylated metabolites. After topical administration of Diclofenac Gel to hand and knee joints Diclofenac can be measured in plasma, synovial tissue and synovial fluid.
Diclofenac Gel is used to relieve pain and reduce swelling in a number of painful conditions affecting the joints and muscles. It relieves rheumatic and muscular pain and reduces swelling and inflammation, e.g., in injuries involving the tendons, ligaments, muscles and joints.
