Pharmgroup:

NSAIDs.

Pharm action:

Rompharm Meloflex is an NSAID, refers to enolic acid derivatives and has anti-inflammatory, analgesic and antipyretic effects.

The pronounced anti-inflammatory effect of meloxicam has been established in all standard models of inflammation. The mechanism of action of meloxicam is its ability to inhibit the synthesis of prostaglandins – known mediators of inflammation.
In vivo meloxicam inhibits the synthesis of prostaglandins in the site of inflammation to a greater extent than in the mucosa of the stomach or kidneys. These differences are due to more selective inhibition of cyclooxygenase-2 (COX-2) compared to cyclooxygenase-1 (COX-1). Inhibition of COX-2 is thought to provide the therapeutic effect of NSAIDs, whereas inhibition of the ever-present COX-1 isoenzyme may cause gastric and renal side effects. The selectivity of meloxicam against COX-2 has been confirmed in various test systems, both in vitro and ex vivo. The selective ability of meloxicam to inhibit COX-2 was shown when using human whole blood as a test system in vitro.

Ex vivo it was found that meloxicam (in doses of 7.5 mg and 15 mg) was more active in inhibiting COX-2, having a greater inhibitory effect on lipopolysaccharide-stimulated prostaglandin E2 production (COX-2-controlled response) than on thromboxane production involved in blood clotting (COX-1-controlled response). These effects were dose-dependent. Ex vivo, meloxicam at the recommended doses was shown to have no effect on platelet aggregation and bleeding time, in contrast to indomethacin, diclofenac, ibuprofen and naproxen, which significantly inhibited platelet aggregation and increased bleeding time.

Pharmacokinetics:

Absorption and distribution

Binding to plasma proteins is 99%. Passes through histohematic barriers, penetrates into the synovial fluid. Concentration in synovial fluid is 50% of the concentration in plasma.

Metabolized in the liver to inactive metabolites.
It is excreted through the gut and kidneys (about equal parts), 5% of the daily dose (through the gut) is unchanged. T1/2 – 20 hours. Plasma clearance – on average 8 ml/min (decreases in old age).

Indications

– rheumatoid arthritis;

– ankylosing spondylitis (Bechterew’s disease).
It is intended for symptomatic therapy, to reduce pain and inflammation at the time of use, does not affect the progression of the disease.

How to take, the dosage

The drug is administered deeply intramuscularly. Intravenous injection is contraindicated.

Intramuscular administration of the drug is indicated only during the first days of treatment. Subsequently, treatment is continued using oral forms (tablets).

Osteoarthritis in the acute phase: 7.5 mg per day, if the condition does not improve, the dose may be increased to 15 mg per day.

Rheumatoid arthritis, ankylosing spondylitis: 15 mg daily. Depending on the therapeutic effect, the dose may be reduced to 7.5 mg per day. The daily dose of meloxicam 15 mg should not be exceeded.

In elderly patients, the recommended dose for long-term therapy of rheumatoid arthritis or ankylosing spondylitis is 7.5 mg daily. In patients at increased risk of side effects, therapy should be started with 7.5 mg daily.

In patients on dialysis with severe renal impairment, the daily dose of meloxicam 7.5 mg should not be exceeded. In patients with mild to moderate renal impairment (CKD greater than 25 ml/min) there is no need to reduce the dose.

In patients with mild to moderate hepatic impairment, there is no need to reduce the dose of the drug.

Interaction

Pharmacodynamic interaction

The simultaneous use of several NSAIDs (including salicylates) may increase the risk of gastrointestinal erosive ulcers due to synergistic effects, so it is not recommended to use meloxicam with other NSAIDs.

When using meloxicam with diuretics, the patient should drink sufficient fluids, and regular medical monitoring of renal function before and during treatment is required.

Combined use with indirect anticoagulants increases the risk of bleeding due to inhibition of platelet function and damage to the gastrointestinal mucosa. Therefore, combined use with NSAIDs and indirect anticoagulants is not recommended.

When combined use of thrombolytic and antithrombotic drugs with meloxicam an increased risk of bleeding is possible (periodic monitoring of blood clotting is necessary).

Simultaneous use with ACE inhibitors and other hypotensive drugs in elderly patients with symptoms of dehydration may provoke acute renal failure. In addition, combined use with meloxicam may reduce their hypotensive effect.

Meloxicam increases the nephrotoxic effect of cyclosporine.

Meloxicam may decrease the effectiveness of contraceptives.

Pharmacokinetic interaction

NSAIDs may increase the concentration of lithium in the blood serum to toxic levels (decreased renal excretion of lithium). Therefore, concomitant use of meloxicam with lithium drugs is not recommended. If it is necessary their combined use should be carefully monitored the content of lithium in the blood serum before, during and after the end of therapy with meloxicam and lithium preparations.

In concomitant use with methotrexate there is increased adverse effect on the hematopoietic system (risk of anemia and leukopenia). Periodic hemogram control is necessary.

Colestyramine accelerates excretion of meloxicam, increasing clearance of meloxicam by 50%, reduces its T1/2 by 13±3 h. This interaction has clinical relevance.

When concomitantly administered with antacids, cimetidine and digoxin, no significant clinical interaction has been noted.

NSAIDs reduce the effectiveness of intrauterine contraceptive devices.

When co-administering meloxicam and drugs that have a known ability to inhibit CYP2C9 and/or CYP3A4 (or are metabolized with the participation of these enzymes), the possibility of pharmacokinetic interaction should be taken into account. The possibility of interaction of meloxicam with oral hypoglycemic agents cannot be excluded.

Concomitant use of meloxicam with selective serotonin reuptake inhibitors increases the risk of gastrointestinal bleeding.

Special Instructions

Caution should be exercised when treating patients with a history of gastrointestinal diseases. Patients with gastrointestinal symptoms should be monitored regularly. In case of gastrointestinal ulceration or gastrointestinal bleeding Meloflex Romfarm should be discontinued.

As with other NSAIDs, gastrointestinal bleeding, ulcers, and perforations potentially life-threatening to the patient may occur at any time during treatment, either with or without warning symptoms or a history of serious gastrointestinal complications. The consequences of these complications are generally more serious in the elderly.

Particular attention should be paid to patients who report developing skin and mucosal adverse events. In such cases discontinuation of Meloflex Rompharm should be considered.

. In patients with decreased RBC and glomerular filtration (dehydration, chronic heart failure, liver cirrhosis, nephrotic syndrome, clinically evident renal diseases, use of diuretics, dehydration after major surgery) there may be clinically evident chronic renal failure which is completely reversible after discontinuation of the drug (daily urine output and renal function should be monitored in such patients at the beginning of therapy).

In case of persistent and significant elevation of transaminases and changes in other liver function parameters, the drug should be discontinued and control tests should be performed.

In patients with increased risk of side effects, treatment should be started at a dose of 7.5 mg. In end-stage chronic renal failure patients on dialysis, the dose should not exceed 7.5 mg/day.

Influence on driving and operating machinery

There are no data on the negative effect of the drug on the ability to drive vehicles or operate machinery. In case of CNS disorders (decreased visual acuity, increased fatigue, dizziness or other disorders) these activities are contraindicated.

Treatment: symptomatic therapy. Forced diuresis, urine alkalinization, hemodialysis are ineffective due to the high degree of binding of meloxicam with plasma proteins. There is no specific antidote.

Pregnancy use

Suppression of prostaglandin synthesis may have undesirable effects on pregnancy and fetal development. Thus, Meloflex Romfarm is contraindicated during pregnancy.

Meloxicam is excreted with the breast milk, so Meloflex Romfarm is contraindicated during lactation. It is necessary to stop breastfeeding while taking the drug.
