Acemetacin is a carboxymethyl ester of indomethacin.

In clinical trials, acemetacin exhibits a better gastric tolerability compared to its active metabolite indometacin. It was developed by E. Merck and Company in Germany as an attempt to provide a safer drug but other than the amelioration on the gastrointestinal effects, the metabolism of acetamicin led to the formation of indomethacin and it kept the same side effects.

Its activity is due to both acemetacin and its major metabolite, indomethacin. It has a role as a prodrug, an EC 1.14.99.1 (prostaglandin-endoperoxide synthase) inhibitor, a non-steroidal anti-inflammatory drug, and a non-narcotic analgesic. It is a N-acylindole, a monocarboxylic acid, a carboxylic ester, an idol-3-yl carboxylic acid and a member of monochlorobenzenes. It derives from an indometacin.
Mechanism of Action of Acemetacin
Acemetacin is a non-selective inhibitor of the production of pro-inflammatory mediators derived from the action of the enzyme COX. COX is essential for the synthesis of prostaglandin E2 and F2 which are molecules derived from fatty acids and stored in the cell membrane. Acemetacin is metabolized and forms its major metabolite indometacin which is also a non-selective inhibitor of COX and exhibits the capacity to inhibit the motility of polymorphonuclear leukocytes and decreased cerebral flow by modulating the nitric oxide pathway and vasoconstriction.
Prostaglandin-endoperoxide synthase activity. Converts arachidonate to prostaglandin H2 (PGH2), a committed step in prostanoid synthesis. Involved in the constitutive production of prostanoids in particular in the stomach and platelets. In gastric epithelial cells, it is a key step in the generation of prostaglandins, such as prostaglandin E2 (PGE2), which plays an important role in cytoprotection. In platelets, it is involved in the generation of thromboxane A2 (TXA2), which promotes platelet activation and aggregation, vasoconstriction and proliferation of vascular smooth muscle cells
Indications of Acemetacin
Acemetacin is not FDA, Canada or EMA approved, but in the countries where it is marketed it is indicated for the symptomatic treatment of pain and swelling in acute infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation of the joints in stiffness, or reduced movement. সহজ বাংলা: জয়েন্টের প্রদাহ।" data-rx-term="arthritis" data-rx-definition="Arthritis means joint inflammation causing pain, swelling, stiffness, or reduced movement. সহজ বাংলা: জয়েন্টের প্রদাহ।">arthritis: Rheumatoid arthritis is an autoimmune joint disease causing inflammation, pain, and swelling. সহজ বাংলা: রোগপ্রতিরোধ ব্যবস্থার ভুল আক্রমণে জয়েন্টের প্রদাহ।" data-rx-term="rheumatoid arthritis" data-rx-definition="Rheumatoid arthritis is an autoimmune joint disease causing inflammation, pain, and swelling. সহজ বাংলা: রোগপ্রতিরোধ ব্যবস্থার ভুল আক্রমণে জয়েন্টের প্রদাহ।">rheumatoid arthritis, osteoarthritis, low back pain, and post-surgical pain.
