Tolmic 200 mg belongs to the fenamate group of NSAIDs and exerts its therapeutic effect mainly by inhibiting the biosynthesis and action of prostaglandins. It inhibits both cyclooxygenase enzymes, COX-1 and COX-2, which are responsible for the production of prostaglandins involved in pain, inflammation, and fever.

In addition to its classical NSAID mechanism, Tolmic 200 mg also inhibits leukotriene B4-mediated chemotaxis of human polymorphonuclear leukocytes, reducing inflammatory cell migration by approximately 25%. This additional mechanism contributes to its enhanced anti-inflammatory activity and effectiveness in migraine-related pain.

Mode of Action

Tolmic 200 mg (N-(2-methyl-3-chlorophenyl) anthranilic acid) inhibits the synthesis of key inflammatory mediators such as prostaglandin E2 (PGE2) and thromboxane B2 (TXB2). Prostaglandins are major contributors to pain, swelling, and inflammation. By reducing their production and directly antagonizing prostaglandin receptors, Tolmic 200 mg provides effective pain relief and anti-inflammatory action.

Pregnancy & Lactation

Tolmic 200 mg is not recommended during pregnancy unless clearly essential, particularly during the first and third trimesters. It is contraindicated in the third trimester. NSAIDs may pass into breast milk in small amounts; therefore, use during lactation should be avoided if possible.

Precautions & Warnings

Caution is required in patients with asthma, bronchospasm, cardiovascular disease, bleeding disorders, hypertension, peptic ulcer history, liver or renal impairment, infections, congestive heart failure, and in elderly patients. Increasing water intake or dose reduction may help reduce dysuria.

Overdose

Symptoms may include headache, nausea, vomiting, abdominal pain, gastrointestinal bleeding, dizziness, drowsiness, tinnitus, convulsions, and coma. Severe cases may result in acute renal failure or liver damage. Treatment is supportive and symptomatic.

Storage Conditions

Store in a cool and dry place, protected from light. Keep out of the reach of children.
