Associated Conditions
Pharmacodynamics
Tenopain Injection 20 mg/vial, an antiinflammatory agent with analgesic and antipyretic properties, is used to treat osteoarthritis and control acute pain.
Mechanism of Action
The antiinflammatory effects of tenoxicam may result from the inhibition of the enzyme cycooxygenase and the subsequent peripheral inhibition of prostaglandin synthesis. As prostaglandins sensitize pain receptors, their inhibition accounts for the peripheral analgesic effects of tenoxicam. Antipyresis may occur by central action on the hypothalamus, resulting in peripheral dilation, increased cutaneous blood flow, and subsequent heat loss.
Absorption
Oral absorption of tenoxicam is rapid and complete (absolute bioavailability 100%).
Protein Binding
99%
Half Life
72 hours (range 59 to 74 hours)
Food Interactions
- Take with food. Food may minimize stomach upset caused by tenoxicam.
Dosage
In acute attacks of gout: The recommended dose for acute attacks of gout is 40 mg once daily for two days followed by 20 mg once daily for a further five days.
In the treatment of chronic disorders: The therapeutic effect of tenoxicam is evident early in treatment but there is a progressive increase in response over time. In chronic disorders, daily doses higher than 20 mg should be avoided since this would increase the frequency and intensity of unwanted reactions without significantly increasing efficacy. For patients needing long-term treatment, a reduction to a daily oral dose of 10 mg may be tried for maintenance.
Special dosage instructions: In principle, the above dosage recommendations also apply to elderly patients and to patients suffering from kidney or liver disease. Because of lack of clinical experience, no dosage recommendations have so far been established for children and adolescents.
