Increased risk of additive hypokalaemia with Amphotericin B inj and K-depleting agents. Increased risk of acute myopathy with neuromuscular blocking agents. May inhibit the effect of anticholinesterases. Additional increase of IOP with anticholinergics (e.g. atropine). May increase or diminish the therapeutic effect of oral anticoagulants. May diminish the therapeutic effect of antidiabetics (e.g. sulfonylurea derivatives) and insulin. May diminish therapeutic effect of antihypertensive agents, including diuretics. Increase in both ciclosporin and corticosteroids activity when used concomitantly. May decrease serum concentration of isoniazid. May increase the risk of digitalis toxicity. Increased clearance with hepatic enzyme inducers (e.g. barbiturates, phenytoin, carbamazepine, rifampicin, primidone, and aminoglutethimide). May decrease clearance and increase the risk of Cushing’s syndrome and adrenal suppression with CYP3A4 inhibitors (e.g. ritonavir) including cobicistat-containing products. May decrease therapeutic effect of somatropin. Increased risk and severity of gastrointestinal bleeding and ulceration associated with NSAIDs. May decrease serum salicylate levels. Increased serum levels with oestrogen (including oral contraceptives). Neurological complications and diminished antibody response with live vaccines.

May attenuate skin test reactions. May cause false-negative results with nitroblue tetrazolium test for bacterial infection. May cause a positive result with anti-doping tests.
Tác dụng
Description: Mechanism of Action: Triamcinolone is a synthetic glucocorticoid with minimal mineralocorticoid effects. It decreases inflammation by suppressing the migration of polymorphonuclear leucocytes and reverses the increased capillary permeability, inhibiting immune reactions by decreasing the activity and volume of the lymphatic system, and prevents adrenal function at high doses. Onset: >24 hours (intra-articular). Duration: 4-6 weeks (intra-articular). Pharmacokinetics: Absorption: Slowly absorbed from the inj site. Distribution: Crosses the placenta, enters breast milk. Excretion: Plasma half-life: Approx 2-5 hours.
