Pharmgroup:
NSAIDs.
Pharmic action:
Amelotex is an NSAID with anti-inflammatory, antipyretic, analgesic effects. It belongs to the class of oxycams; a derivative of enolic acid.
Meloxicam is a non-steroidal anti-inflammatory drug with analgesic, anti-inflammatory and antipyretic effects.
The anti-inflammatory action is associated with inhibition of the enzymatic activity of cyclooxygenase-2 (COX-2), which is involved in the biosynthesis of prostaglandins in the area of inflammation.
To a lesser extent, meloxicam acts on cyclooxygenase-1 (COX-1), which is involved in the synthesis of prostaglandin, which protects the mucosa of the gastrointestinal tract and is involved in the regulation of blood flow in the kidneys.
Pharmacokinetics:
Amelotex is well absorbed from the gastrointestinal tract, the absolute bioavailability of meloxicam is 89%. Simultaneous intake of food does not change absorption. When using the drug Amelotex orally in doses of 7.5 and 15 mg, its concentrations are proportional to the doses. Equilibrium concentrations are reached within 3-5 days. With long-term use of the drug (more than 1 year), the concentrations are similar to those observed after the first achievement of equilibrium concentrations. Binding to plasma proteins is more than 99%. The range of differences between maximal and basal concentrations of the preparation after its once-daily use is relatively small, 0.4 – 1.0 µg/ml, and 0.8-2.0 µg/ml, when using 7.5 mg dosage, and 0.8-2.0 µg/ml, when using 15 mg dosage (Cmin and Cmax values are indicated, respectively). Meloxicam penetrates through histohematic barriers, the concentration in synovial fluid reaches 50% of the maximum concentration of the drug in plasma.
It is almost completely metabolized in the liver to form four pharmacologically inactive derivatives. The main metabolite, 5′-carboxymeloxicam (60% of the dose value), is formed by oxidation of the intermediate metabolite, 5′-hydroxymethylmeloxicam, which is also excreted, but to a lesser extent (9% of the dose value). In vitro studies have shown that CYP 2C9 isoenzyme plays an important role in this metabolic transformation, CYP 3A4 isoenzyme has additional importance. Peroxidase, the activity of which probably varies individually, is involved in the formation of the other two metabolites (which constitute, respectively, 16% and 4% of the value of the drug dose).
Extracted equally through the intestine and kidneys, mainly as metabolites. Less than 5% of daily dose is excreted unchanged in intestine, in urine the drug is excreted unchanged only in trace amounts. The half-life (T1/2) of meloxicam is 15-20 hours. Plasma clearance averages 8 ml/min. The drug clearance is decreased in elderly patients. The volume of distribution is low and averages 11 l. Hepatic or renal insufficiency of moderate severity has no significant effect on the pharmacokinetics of meloxicam.
Indications
Active ingredient
Composition
1 tablet contains meloxicam 15 mg.
How to take, the dosage
The drug is taken orally with meals once a day.
The recommended dosing regimen:
– Rheumatoid arthritis: 15 mg per day. Depending on the therapeutic effect the dose can be reduced to 7.5 mg per day.
– Osteoarthritis: 7.5 mg per day. In case of ineffectiveness the dose can be increased up to 15 mg per day.
– Ankylosing spondylitis: 15 mg per day. Maximum daily dose should not exceed 15 mg.
In patients at increased risk of side effects, as well as in patients with significant renal impairment who are on hemodialysis, the dose should not exceed 7.5 mg per day.
Interaction
Concomitant use with other nonsteroidal anti-inflammatory drugs (as well as with acetylsalicylic acid) increases the risk of erosive ulcerative lesions and bleeding from the gastrointestinal tract. When concomitant use with hypotensive drugs, the effectiveness of the latter may decrease.
Simultaneous use with lithium preparations may lead to cumulation of lithium and increase its toxic effects (it is recommended to control the lithium concentration in the blood).
In concomitant use with methotrexate there is an increased side effect of the latter on the hematopoietic system (risk of anemia and leukopenia, periodic control of total blood count is indicated).
Concomitant use with diuretics and with cyclosporine increases the risk of renal failure.
Concomitant use with intrauterine contraceptives may decrease the effectiveness of the latter.
In concomitant use with anticoagulants (heparin, ticlopidine, warfarin), as well as with thrombolytic drugs (streptokinase. fibrinolysin) the risk of bleeding increases (periodic control of blood clotting is necessary).
In concomitant use with colestiramine, as a result of binding meloxicam its excretion through the gastrointestinal tract is increased.
Concomitant use with selective serotonin reuptake inhibitors increases the risk of gastrointestinal bleeding.
Special Instructions
In case of peptic ulcers or gastrointestinal bleeding, development of side effects on the skin and mucous membranes the drug should be discontinued.
In patients with decreased volume of circulating blood and decreased glomerular filtration (dehydration, chronic heart failure, surgical operations) there may be clinically expressed 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 treatment).
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 with 7.5 mg dose.
In end-stage chronic renal failure patients on dialysis, the dose should not exceed 7.5 mg/day.
During the treatment period caution should be exercised while driving motor transport and engaging in other potentially hazardous activities requiring increased concentration and rapid psychomotor reactions (if dizziness and somnolence occur).
Contraindications
Hypersensitivity to the active substance or excipients;
Contraindicated in the period after coronary artery bypass grafting;
uncompensated heart failure;
complete or incomplete combination of bronchial asthma, recurrent polyposis of the nose and sinuses and intolerance to acetylsalicylic acid and other non-steroidal anti-inflammatory drugs (incl.Ñ. In anamnesis);
Erosive-ulcerative changes of the mucosa of the stomach or duodenum, active gastrointestinal bleeding;
Inflammatory bowel diseases (non-specific ulcerative colitis, Crohn’s disease);
Cerebrovascular bleeding or other bleeding;
Severe hepatic insufficiency or active liver disease;
Severe renal insufficiency in patients not undergoing dialysis (creatinine clearance less than 30 ml/min), progressive renal disease including.
Pregnancy, breastfeeding;
Childhood under 15 years old.
With caution
. In order to decrease the risk of the development of undesirable effects the minimal effective dose should be used in ischemic heart disease, cerebrovascular disease, congestive heart failure, dyslipidemia/hyperlipidemia, diabetes, peripheral arterial disease, smoking, creatinine clearance less than 60 ml/min, anamnestic data on the development of gastrointestinal ulcers, the presence of Helicobacter pylori infection, the elderly, long-term use of nonsteroidal anti-inflammatory drugs, frequent use of alcohol, severe somatic diseases, concomitant therapy with the following drugs: anticoagulants (e.g., warfarin), antiaggregants (e.g., acetylsalicylic acid, clopidogrel), oral glucocorticosteroids (e.g., prednisolone), selective serotonin reuptake inhibitors (e.g., citalopram, fluoxetine, paroxetine, sertraline).

Overdose
Symptoms: impaired consciousness, nausea, vomiting, epigastric pain, gastrointestinal bleeding, acute renal failure, liver failure, respiratory arrest, asystole.
Treatment: there is no specific antidote; in case of overdose of the drug, gastric lavage, administration of activated charcoal (within the next hour), symptomatic therapy should be carried out. Colestiramine accelerates excretion of the drug from the body. Forced diuresis, hemodialysis are ineffective due to high binding of the drug to blood proteins.
Pregnancy use
