Texared, 20 mg 10 pcs

Tenoxicam, which is a thienothiazine derivative of oxycam, is an NSAID. In addition to its anti-inflammatory, analgesic and antipyretic effects, the drug also inhibits platelet aggregation. Tenoxicam exerts its anti-inflammatory effect by inhibiting the activity of COX isoenzymes involved in arachidonic acid metabolism and thereby suppresses PG synthesis.

Tenoxicam has no effect on the activity of lipoxygenases. In addition, tenoxicam suppresses some functions of leukocytes, including phagocytosis, histamine release and decreases the content of active radicals in the inflammation focus.

Pharmacokinetics

The drug is rapidly absorbed from the gastrointestinal tract in unchanged form. C_max is reached 2 hours after drug intake. When the drug is taken after meals or together with antacids, the rate but not the degree of absorption is reduced. The average T_1/2 is 70 h. Tenoxicam is fully absorbed, its bioavailability is 100%. In the blood the drug is 99% bound to proteins.

The drug penetrates well into the synovial fluid and is characterized by low systemic clearance and prolonged T_1/2, which allows Tenoxicam to be taken once a day.

2/3 of the taken dose of the drug is excreted with urine, 1/3 with feces. There is no cumulation of tenoxicam when prolonged use; serum content of the drug in this case is 10-15 µg/ml.

In acute attacks of gout, 40 mg/day for the first 2 days, then 20 mg/day for 5 days.

Elderly patients are prescribed in a dose of 20 mg/day.

Interaction

Reduces the effectiveness of uricosuric drugs, hypotensive drugs and diuretics; increases the effect of anticoagulants, antiaggregants, fibrinolytics, adrenal hormone side effects, GCS and estrogen reduces the effectiveness increases the hypoglycemic effect of sulfonylurea derivatives.

increases blood concentrations of lithium drugs, methotrexate.

The inducers of microsomal oxidation in the liver (phenytoin, ethanol, barbiturates, rifampicin, phenylbutazone, tricyclic antidepressants) increase the production of hydroxylated active metabolites.

Antacids and colestyramine decrease absorption.

Other NSAIDs – risk of side effects, especially gastrointestinal side effects.

Myelotoxic drugs increase the manifestations of hematotoxicity of the drug.

Special Instructions

During treatment it is necessary to monitor peripheral blood count and functional state of the liver and kidneys, prothrombin index (with indirect anticoagulants), blood glucose concentration (with oral hypoglycemic drugs).

If it is necessary to determine 17-ketosteroids, the drug should be discontinued 48 hours before the study.

A few days before surgical intervention, the drug should be withdrawn.

The possibility of sodium and water retention in the body must be considered when prescribed with diuretics in patients with arterial hypertension and CHF.

To reduce the risk of gastrointestinal adverse events, the lowest effective dose should be used for the shortest possible course.

Impact on the ability to drive and operate machinery. One of the undesirable effects of the drug is dizziness; this should be taken into account in situations requiring the patient’s close attention, such as driving a motor vehicle or operating complex technical devices. During the treatment it is necessary to be cautious while driving vehicles and engaging in other potentially dangerous activities requiring high concentration and quick psychomotor reactions.
