Pharmacological properties
Pharmacodynamics
Voltaren Patch is a non-steroidal anti-inflammatory drug for external use. It is a base with an adhesive layer containing diclofenac, which has pronounced anti-inflammatory and analgesic properties. The mechanism of action of diclofenac is based on the inhibition of prostaglandin synthesis.
The drug provides an analgesic and anti-inflammatory effect at the site of application, as a result of which the pain syndrome is eliminated and the swelling associated with the inflammatory process decreases.
Pharmacokinetics
The amount of diclofenac absorbed systemically from the drug over 24 hours is similar to that when using an equivalent amount of Voltaren Emulgel (gel for external use).
The binding of the substance with plasma proteins is 99.7%, mainly with albumin (99.4%).
The total systemic clearance from plasma is 263 ± 56 ml / min.
Diclofenac and its metabolites are mainly excreted in the urine. The final T 1/2 (half-life) in blood plasma is from 1 to 2 hours. Four metabolites, including 2 active ones, also have a short T 1/2 - 1–3 hours. One of the metabolites - 3'-hydroxy-4'-methoxydiclofenac - has a longer T 1/2, but it is not active.
In case of impaired renal function, accumulation of diclofenac and its metabolites does not occur.
Indications for use
- joint pain (including knee joints, finger joints) against the background of rheumatoid arthritis, osteoarthritis;
- back pain associated with degenerative / inflammatory diseases of the spine (lumbago, osteoarthritis, radiculitis, sciatica);
