Global Nonsteroidal Anti-inflammatory Drugs (NSAIDs) Market is expected to grow at a higher CAGR in the forecast period. NSAIDs (nonsteroidal anti-inflammatory drugs) decrease inflammation but are not related to steroids that also reduce inflammation. NSAIDs work by plummeting the production of prostaglandins. NSAIDs are a drug class that groups together drugs that provide analgesic (pain killing) and antipyretic (fever-reducing) effects, and, in superior doses, anti-inflammatory effects. Prostaglandins are chemicals that promote inflammation, pain, and fever. They also protect the lining of the stomach and intestines from the damaging effects of acid, encourage blood clotting by activating blood platelets, and promote normal function of the kidneys.

The enzymes that produce
prostaglandins are called cyclooxygenases (COX). There are two types of COX
enzymes, viz COX-1 and COX-2. Both the enzymes produce prostaglandins that
promote inflammation, pain, and fever. However, only COX-1 produces
prostaglandins that activate platelets, protect the stomach and intestinal
lining.NSAIDs block COX enzymes, and reduce production of prostaglandins.
Therefore, inflammation, pain, and fever are reduced. Since the prostaglandins
that protect the stomach and promote blood clotting are also reduced, NSAIDs
that block both COX-1 and COX-2 can cause ulcers in the stomach and intestines,
and increase the risk of bleeding.
Aspirin, the only NSAID able to
irrevocably inhibit COX-1, is also indicated for inhibition of platelet
aggregation. This is useful for the management of arterial thrombosis and
prevention of adverse cardiovascular events. Aspirin inhibits platelet aggregation
by inhibiting the action of thromboxane A2.In general, the NSAIDs inhibit both
- COX-1 and COX-2. Most NSAIDs are mainly COX-1 selective (e.g., aspirin,
ketoprofen, indomethacin, piroxicam, sulindac). Others are measured slightly
selective for COX-1 (eg, ibuprofen, naproxen, diclofenac) and the others may be
considered slightly selective for COX-2 (eg, etodolac, nabumetone, and
meloxicam).
The mechanism of action of
celecoxib and rofecoxib is primarily selective inhibition of COX-2; at therapeutic
concentrations, the COX-1 isoenzyme is not inhibited thus GI toxicity may be
decreased.Other mechanisms that may supply to NSAID anti-inflammatory activity
include the reduction of superoxide radicals, induction of apoptosis,
inhibition of adhesion molecule expression, reduce of nitric oxide synthase,
reduce of proinflammatory cytokine levels (tumor necrosis factor-a,
interleukin-1), modification of lymphocyte activity, and alteration of cellular
membrane functions. Central analgesic activity has been established in animal
pain models by some NSAIDs such as diclofenac, ibuprofen, indomethacin, and
ketoprofen.
This could be because of the
interference of prostaglandin (PGE1, F2 and F2a) mediated pain formation or
with transmitters or modulators in the nociceptive system. The other proposals
include the central action mediated by opioid peptides, inhibition of serotonin
release, or inhibition of excitatory amino acids or N-methyl-D-aspartate
receptors.
NSAIDs are mainly effective
against the type of pain in which PGs sensitize pain receptors (inflammation
and tissues) including the pain of arthritis, bursitis, pain of muscular
andmvascula origin and dysmenorrhea. The efficiency of these agents against
headache may result from their aptitude to inhibit PG-mediated cerebral
vascular vasodilation.

NSAIDs are useful in the
management of post-operative dental pain following invasive dental events such
as dental extraction. When not contra-indicated they are favored over the use
of paracetamol without help due to the anti-inflammatory result they give. When
used in mixture with paracetamol the analgesic effect has been established to
be enhanced.
