Anilic Tablet 200 mg

Anilic Tablet 200 mg Uses, Dosage, Side Effects, Food Interaction and all others data.

Anilic Tablet 200 mg inhibits the biosynthesis of prostaglandins, and it also presents inhibitory actions on the prostaglandin receptors. As commonly thought, the mechanism of action of tolfenamic acid is based on the major mechanism of NSAIDs which consists of the inhibition of COX-1 and COX-2 pathways to inhibit prostaglandin secretion and action and thus, to exert its anti-inflammatory and pain-blocking action. Nonetheless, some report currently indicates that tolfenamic acid inhibits leukotriene B4 chemotaxis of human polymorphonuclear leukocytes leading to an inhibition of even 25% of the chemotactic response. This activity is a not ligand specific additional anti-inflammatory mechanism of tolfenamic acid

Studies have shown that tolfenamic acid presents a non-dose dependent partial inhibition of irritant-induced temperature rise as well as a dose-dependent inhibition of skin edema. By studying its NSAID properties more closely, it was noted a dose-related inhibition of serum thromboxane which indicated the inhibition of COX-1. In the same line, there was noted a inhibition of prostaglandin E2 synthesis which marks a related COX-2 inhibition. The maximal inhibition of thromboxane was greater than 80% as well as is proven to be a potent prostaglandin E inhibitor.

Protein binding

Tolfenamic acid presents high protein binding properties reaching 99.7% of the administered dose. Studies have studied the changes in protein binding depending on the presence of certain disorders that modify the dialysis equilibrium. These studies verify that modifications in blood creatinine, urea and bilirubin can significantly alter the concentration of unbound tolfenamic acid. The main binding structure is predicted to be related to lipid membrane structures.

Dosage

Anilic Tablet 200 mg dosage

Acute migraine attacks:

  • Adult: 200 mg when 1st symptoms appear may be repeated once after 1-2 hr.
  • Renal impairment: Dose adjustments may be needed. Severe: Avoid.

Mild to moderate pain:

  • Children: A pediatric dosage regimen has not yet been established.
  • Adult: 100-200 mg tid.
  • Renal impairment: Dose adjustments may be needed. Severe: Avoid. It should be taken with food. Take water/ or immediately after meals.

Preclinical safety data: The therapeutic index for Anilic Tablet 200 mg is high, and gastrointestinal ulceration and kidney changes have only been seen with oral doses approximately 6-10 times the maximum therapeutic dose recommended for tolfenamic acid.

Special Precautions: Asthma, bronchospasm, bleeding disorders, cardiovascular diseases, history of peptic ulceration, hypertension, patients with infections, liver, cardiac, or renal function impairment. Increase water intake or dose reduction to reduce dysuria. CHF; elderly; lactation.

Side Effects

Dysuria especially in males; diarrhoea, nausea, epigastric pain, vomiting, dyspepsia, erythema, headache. Tremor, euphoria, fatigue, pulmonary infiltration, & haematuria. Potentially Fatal: Blood dyscrasias, toxic hepatitis.

Toxicity

Anilic Tablet 200 mg has a relatively low acute toxicity with LD50 values in 200-1000 mg/kg. The metabolites of tolfenamic acid are reported to have an even less important toxicity. Some of the expected toxicity is related to the presence of gastrointestinal effects such as gut ulceration and renal papillitis.

Precaution

As is the case with other NSAIDs, tolfenamic acid should be used with caution in patients with a history of gastrointestinal ulceration, or impaired liver or kidney function.

The therapeutic index for tolfenamic acid is high, and gastrointestinal ulceration and kidney changes have only been seen with oral doses approximately 6-10 times the maximum therapeutic dose recommended for tolfenamic acid. In human volunteers, tolfenamic acid did not affect renal function.

Interaction

The rate of absorption of Anilic Tablet 200 mg increases with metoclopramide and magnesium hydroxide and decreases with aluminium hydroxide. Risk of bleeding with anticoagulants and other NSAIDs increases when use with Anilic Tablet 200 mg. It decreases antihypertensive response to loop diuretics, β-blockers and ACE inhibitors. Co-administration increases plasma concentrations of lithium, methotrexate and cardiac glycosides. It also increases the risk of nephrotoxicity with ACE inhibitors, ciclosporin, tacrolimus or diuretics.

Volume of Distribution

The volume of distribution is of 1.79-3.2 L/kg. When tested intravenously, the reported steady-state volume of distribution was 0.33 L/kg.

Elimination Route

Anilic Tablet 200 mg pharmacokinetic is marked by a short tmax of 0.94-2.04 h. It also presented a linear pharmacokinetic profile with an AUC from 13-50 mcg/ml.h if administered in a dose of 2-8 mg/kg respectively. The oral absorption is delayed and it gives a mean lag-time to absorption of 32 min. The peak plasma concentration of 11.1 mcg/ml. The bioavailability of tolfenamic acid is around 75%.

Half Life

The estimated half-life of tolfenamic acid is 8.01-13.50 hours. When tested intravenously, the reported half-life was 6.1h.

Clearance

The estimated clearance rate of tolfenamic acid is 0.142-0.175 L.h/kg. When tested intravenously, the reported clearance rate was 72.4 ml.h/kg.

Elimination Route

Anilic Tablet 200 mg is cleared relatively fast and it undergoes by hepatic metabolism where the produced metabolites are renally cleared as glucuronic acid conjugates. Most of the elimination occurs by extrarenal mechanisms in which the unchanged drug together with its glucuronide in urine accounts for only 8.8% of the administered dose.
