• History of gastrointestinal bleeding or perforation associated with previous NSAID treatment;
• Cerebrovascular or other active bleeding;
• Severe hepatic dysfunction or renal impairment;

4. PHARMACOLOGICAL PROPERTIES
4.1 Pharmacodynamic properties
Non-steroidal anti-inflammatory and anti-rheumatic agents;
Acetic acid derivatives and related substances
ATC code: M01AB05
Diclofenac is a non-steroidal anti-inflammatory/anti-rheumatic agent, which has proved effective by
inhibiting prostaglandin synthesis in the usual inflammation models in animal studies. In human
beings diclofenac reduces pain, swelling and fever which are caused by inflammation. Diclofenac
also inhibits platelet aggregation caused by ADP and collagen.
4.2 Pharmacokinetic properties
After oral administration of the usual gastroresistant pharmaceutical forms diclofenac is fully
absorbed distal to the stomach. Maximum plasma levels are attained, depending on the duration of
the passage through the stomach, after 1 - 16 hours, the mean being after 2 - 3 hours. After IM
administration, maximum plasma levels are attained after 10 - 20 minutes; after rectal
administration after about 30 minutes. Orally administered diclofenac is subject to a marked
first-pass effect; only 35 - 70% of the active substance absorbed reaches the post-hepatic circulation
unchanged. About 30% of the active substance is eliminated in metabolised form with the faeces.
About 70% is excreted by the kidneys after hepatic metabolic conversion (hydroxylation and conjugation) as pharmacologically inactive metabolites. The elimination half-life, which is largely independent of liver and renal function, is about 2 hours. Plasma protein binding is about 99%.
