Tenoxicam has a high degree of binding to albumin and can, like all NSAIDs, enhance the anticoagulant effect of warfarin and other anticoagulants. It is recommended to monitor indicators at ωin the local application with anticoagulants and hypoglycemic drugs for oral administration, especially in the initial stages of administration of Arthoksan.
There was no possible interaction with digoxin.
As with other NSAIDs, it is recommended that the drug be used with caution when cyclosporine is used because of the increased risk of developing nephrotoxicity.
Joint use with quinolones may increase the risk of seizures.
Salicylates can displace tenoxicam from the bond with albumin and, accordingly, to increase the clearance and volume of distribution of the drug. It is necessary to avoid the simultaneous use of salicylates or two or more NSAIDs (increased risk of complications from the gastrointestinal tract).
There is evidence that NSAIDs reduce the excretion of lithium. In connection with these patients receiving lithium therapy, should more often monitor the concentration of lithium in the blood.
NSAIDs can cause sodium, potassium and fluid retention in the body, disrupting the action of natriuretic diuretics. This should be remembered when combined with such diuretics in patients with CHF and hypertension.
With caution, it is recommended to use NSAIDs in conjunction with methotrexate, NSAIDs reduce the excretion of methotrexate and may increase its toxicity.
NSAIDs should not be used within 8-12 hours after the administration of mifepristone, tk. can reduce its effect.
It is necessary to take into account the increased risk of developing gastrointestinal bleeding when combined with corticosteroids.
Reduces the effectiveness of uricosuric medicines, strengthens the effect of anticoagulants, fibrinolytics, side effects of mineralocorticosteroids and glucocorticosteroids, estrogens; reduces the effectiveness of antihypertensive drugs and diuretics.
Inductors of microsomal oxidation in the liver (phenytoin, ethanol, barbiturates, rifampicin, phenylbutazone, tricyclic antidepressants) increase the production of hydroxylated active metabolites. Co-administration with antiplatelet agents and selective serotonin reuptake inhibitors increases the risk of developing gastrointestinal bleeding.
Cardiac glycosides when taken together with NSAIDs can increase heart failure, reduce the rate of glomerular filtration and increase the plasma level of cardiac glycosides.
There was no interaction with the use of tenoxicam with cimetidine. There was no clinically significant interaction in the treatment with tenoxicam and penicillamine or parenteral gold.
Increased risk of nephrotoxicity in the combined use of NSAIDs with tacrolimus.
Increased risk of hematological toxicity when using NSAIDs with zidovudine.
