FLAMADEX PILLS COATED 25 MG

Mechanism of action

NSAIDs, a derivative of propionic acid. It has an analgesic, anti-inflammatory and antipyretic effect. The mechanism of action is associated with inhibition of prostaglandin synthesis at the COX-1 and COX-2 levels.

Analgesic effect occurs 30 minutes after oral administration or parenteral administration. The duration of analgesic action after oral administration is 4-6 hours, after parenteral administration in a dose of 50 mg - about 4-8 hours.

When combined with opioid analgesics, dexketoprofen significantly (up to 30-45%) reduces the need for opioids.

Pharmacokinetics

Suction

After taking the drug inside CmaxDexketoprofen in human serum is reached on average in 30 minutes (15-60 minutes). Simultaneous ingestion slows down the absorption of the drug. The values ​​of AUC after single and repeated doses are similar, which indicates the absence of drug accumulation.

After i / m administration of dexketoprofen Cmaxin serum is reached on average after 20 minutes (10-45 minutes). AUC after a single injection in a dose of 25-50 mg is proportional to the dose, as with the / m, and with a / in the introduction. The corresponding pharmacokinetic parameters are similar after a single and repeated intramuscular or intravenous injection, which indicates the absence of drug accumulation.

Distribution

Dexketoprofena is characterized by a high level of plasma protein binding - 99%. Average v valuedis less than 0.25 l / kg, half-time is about 0.35 h.

Metabolism and excretion

Metabolism of dexketoprofen mainly occurs by conjugation with glucuronic acid, followed by excretion by the kidneys.

T1/2 Dexketoprofen trometamol is about 1-2.7 hours.

Pharmacokinetics in special clinical situations

In the elderly, there is an increase in the duration of T1/2 (both after a single dose, and after repeated intramuscular injection or intravenous administration), on average, up to 48% and a decrease in the total clearance of the drug.

Indications

- relief of pain syndrome of various genesis (including postoperative pain, pain in bone metastases, post-traumatic pain, pain in renal colic, algomenorrhea, sciatica, sciatica, neuralgia, toothache);

special instructions

Flamadex® should be used with caution in patients with a history of allergies.

Care must be taken when prescribing the drug Flamadex® patients with violations of the gastrointestinal tract or gastrointestinal diseases in history. In case of gastrointestinal bleeding or ulcer treatment with Flamadex® should cancel.

It has been clinically proven that the simultaneous use of dexketoprofen and preparations of low molecular weight Heparin in prophylactic doses in the postoperative period does not change the clotting parameters. However, with simultaneous use of the drug Flamadex® With other drugs that affect blood clotting, careful medical monitoring of the blood clotting system is necessary. Dexketoprofen may cause reversible inhibition of platelet aggregation.

Like other NSAIDs, Flamadex® can lead to increased creatinine concentrations and plasma nitrogen levels. Like other prostaglandin synthesis inhibitors, Flamadex® can have a side effect on the urinary system, which can lead to the development of glomerulonephritis, intestinal nephritis, papillary necrosis, nephrotic syndrome and acute renal failure .

As with the use of other NSAIDs, there may be a slight transient increase in some indicators of liver function, a significant increase in the activity of AST and ALT in serum. At the same time, the control of liver and kidney functions is necessary in elderly patients. In the case of a significant increase in the relevant indicators Flamadex® should cancel.

Flamadex® should be used with caution in patients with chronic heart failure I-II functional class by NYHA.
