How does ibuprofen work pharmacology?
Ibuprofen is a non-selective inhibitor of an enzyme called cyclooxygenase (COX), which is required for the synthesis of prostaglandins via the arachidonic acid pathway. COX is needed to convert arachidonic acid to prostaglandin H2 (PGH2) in the body.
How is ibuprofen metabolised?
Ibuprofen is almost completely metabolized, with little to no unchanged drug found in the urine [1,9,12]. The primary route of elimination is oxidative metabolism by CYP enzymes to inactive metabolites (Fig. 1).
How does ibuprofen work on inflammation?

Why is ibuprofen coated?
About 0.04% of drug was released in the acidic phase and 99.05% in the basic medium. These results reflect that ibuprofen can be successfully enteric coated in order to prevent its release in the stomach and facilitate rapid release of the drug in the duodenum, due to the presence of superdisintegrant.
Is ibuprofen acidic or basic?
Ibuprofen is a relatively weak acid (pka 4.4) and its solubility in water or at acid pHis very low. This results in a relatively long residence time in the acid environment of the stomach, which slows down absorption of the substance.
