Oxicam

Oxicam is a class of non-steroidal anti-inflammatory drugs (NSAIDs),[2] meaning that they have anti-inflammatory, analgesic, and antipyretic therapeutic effects. Oxicams bind closely to plasma proteins.[1] Most oxicams are unselective inhibitors of the cyclooxygenase (COX) enzymes. The exception is meloxicam with a slight (10:1) preference for COX-2, which, however, is only clinically relevant at low doses.[3]

Piroxicam, the most popular drug of the oxicam class.[1]

The most popular drug of the oxicam class is piroxicam.[1] Other examples include: ampiroxicam, droxicam, pivoxicam, tenoxicam, lornoxicam,[1] and meloxicam.

Isoxicam has been suspended as a result of fatal skin reactions.[1]

Chemistry edit

The physico-chemical characteristics of these molecules vary greatly depending upon the environment.[4]

In contrast to most other NSAIDs, oxicams are not carboxylic acids. They are tautomeric, and can exist as a number of tautomers (keto-enol tautomerism), here exemplified by piroxicam:[2] 

Side effects edit

The oxicams are associated with drug-related erythema multiforme (EM), Stevens–Johnson syndrome, and toxic epidermal necrolysis (TEN). This association is one of the reasons oxicams are not regularly prescribed.
