Meclofenamic acid
An article about the non-steroidal anti-inflammatory drug Meclofenamic acid
Meclofenamic acid is a non-steroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. It belongs to the class of fenamates and is known for its ability to inhibit cyclooxygenase enzymes, which play a key role in the inflammatory process.
Pharmacology[edit | edit source]
Meclofenamic acid works by inhibiting the activity of cyclooxygenase (COX) enzymes, specifically COX-1 and COX-2. These enzymes are responsible for the conversion of arachidonic acid to prostaglandins, which are mediators of inflammation, pain, and fever. By reducing the production of prostaglandins, meclofenamic acid alleviates symptoms associated with inflammatory conditions.
Medical uses[edit | edit source]
Meclofenamic acid is primarily used for the treatment of rheumatoid arthritis, osteoarthritis, and mild to moderate pain. It is also used to manage dysmenorrhea, which is the pain associated with menstruation.
Side effects[edit | edit source]
Common side effects of meclofenamic acid include gastrointestinal disturbances such as nausea, vomiting, diarrhea, and abdominal pain. More serious side effects can include gastrointestinal bleeding, ulceration, and renal impairment. Patients are advised to use the lowest effective dose for the shortest duration necessary to minimize the risk of adverse effects.
Contraindications[edit | edit source]
Meclofenamic acid is contraindicated in patients with known hypersensitivity to NSAIDs, those with active peptic ulcer disease, and individuals with a history of asthma attacks or allergic reactions after taking aspirin or other NSAIDs.
Mechanism of action[edit | edit source]
The primary mechanism of action of meclofenamic acid is the inhibition of the cyclooxygenase enzymes, which reduces the synthesis of prostaglandins and thromboxanes. This action decreases inflammation, pain, and fever, which are common symptoms in various inflammatory conditions.
History[edit | edit source]
Meclofenamic acid was developed in the 1960s as part of the fenamate class of NSAIDs. It was introduced to the market as a prescription medication for the treatment of inflammatory conditions and pain.
