Mechanism of pharmacological action
The pharmacological effect of the drug is based on its ability to affect inflammatory enzymes. In low doses, Meloxicamum exhibits selective COX-2 inhibition, which reduces the severity of inflammatory responses and pain.
Pharmacokinetics and dosing schedule
A key feature of the drug is its prolonged half-life. This exact pharmacokinetic property ensures a prolonged therapeutic effect and allows for a convenient dosing schedule: the drug is prescribed only once a day.
Clinical indications
The drug is used in rheumatology and orthopedics for the treatment of chronic joint and spinal diseases. Main indications:
- Rheumatoid arthritis;
- Ankylosing spondylitis (Bekhterev's disease);
- Osteoarthritis.
Safety profile and adverse effects
The use of Meloxicamum requires safety monitoring due to specific risks:
- A high incidence of gastrointestinal disorders has been documented.
- The prolonged half-life creates an increased risk of cumulation (accumulation) of the active substance in the body.
- Drug cumulation directly leads to the development of undesirable toxic effects.
Take meloxicam once a day — it has a long half-life, but keep an eye on the stomach and drug accumulation (cumulation)!
