What does the instruction to Ketonal Duo tell us?
Pharmacological effects
This drug is a non-steroidal anti-inflammatory drug derived from propionic acid. It can have an analgesic, and at the same time, an anti-inflammatory and antipyretic effect. "Ketonal Duo" can block the action of "COX-1" enzymes, and in addition, "COX-2", and partially affects lipoxygenase, which leads to suppression of the process of prostaglandin synthesis.
This drug maystabilize lysosomal membranes, and at the highest concentrations, ketoprofen leads to suppression of the synthesis of leukotrienes and bradykinin. The active ingredient, ketoprofen, does not have any negative effect on the state of articular cartilage.
Drug pharmacokinetics
"Ketonal Duo" is a dosage form that differs from the already familiar capsules in the way the main component is released. Modified release capsules include two pellet options: white and yellow. The active substance (ketoprofen) can be released very quickly from white pellets, and from yellow ones, on the contrary, slowly. This results in a combination of rapid and prolonged exposure.
In terms of the strength of its effect, "Ketonal Duo" is not inferior to injections.
The presented drug is well absorbed immediately after ingestion. The bioavailability of ketoprofen in the form of standard capsules and those with modified release is 90%.
Reception of products does not affect the bioavailability of ketoprofen, but reduces the rate of absorption. After ingestion of the active substance at a dose of 150 milligrams in the form of modified-release capsules, the maximum concentration is 9036 nanograms per milligram within one and a half hours. This is confirmed by the instructions for Ketonal Duo.
Drug distribution and metabolism
Ketoprofen binding to plasma protein (i.e. albumin) is approximately 99%. Ketoprofen easily penetrates into the composition of the synovial fluid, where it reaches a 30% plasma concentration. Significant concentrations of the active substance in the synovial fluid are stable and last up to 30 hours, as a result of which the presence of pain and stiffness in the joints decreases for a long period of time.
Ketoprofen may be extensively metabolized by a liver microsomal enzyme that can bind to glucuronic acid and is then excreted as a glucuronide. There are no active metabolites of ketoprofen.
Approximately 80% of the active ingredient is excreted in the urine, predominantly in the form of ketoprofen glucuronide. 10% leaves the body through the intestines. Against the background of the use of ketoprofen at a dose of 100 milligrams or more, excretion through the kidneys may be difficult.

Other product information
In patients who suffer from severe renal insufficiency, a large proportion of the drug may be excreted through the intestines. Against the background of taking in high dosages, hepatic clearance also increases. Through the intestines, up to 40% of the drug is excreted.
In patients who suffer from liver failure, the plasma concentration of the main component is increased by two times, which is most likely due to hypoalbuminemia, and also due to high levels of unbound ketoprofen. Such patients are recommendedprescribe such medications in minimal therapeutic doses.
In patients suffering from kidney failure, the clearance of ketoprofen is reduced. However, dose adjustment is required only in cases of severe deficiency. In older people, the metabolism with elimination of ketoprofen is much slower, which is of clinical importance only for patients with severe renal insufficiency.

Patients may also have heart failurealong with increased pressure and vasodilation. The respiratory system reacts with an exacerbation of bronchial asthma, the appearance of bronchospasm and rhinitis. It must be said that bronchospasms are predominantly observed in patients who have hypersensitivity to non-steroidal anti-inflammatory drugs.
The digestive system may experience nausea, vomiting, dyspepsia, abdominal pain, constipation, diarrhea, bloating, gastritis, peptic ulcers, and stomatitis with this drug. Rarely, exacerbation of colitis with Crohn's disease, intestinal bleeding and perforation is observed. The liver and biliary tract react with hepatitis, an increase in the level of transaminases, and in addition, bilirubin.
Rash and itching may appear on the skin. Photosensitivity may also occur along with alopecia, urticaria, angioedema, erythema, bullous rash, and toxic epidermal necrolysis.
The urinary system may respond with acute renal failure, interstitial nephritis, nephritic syndrome, and abnormal kidney function.
Other side effects include edema with increased fatigue, weight gain in patients, and so on.
Overdose
Symptoms of an overdose of Ketonal Duo painkillers, like other cases with an excess of ketoprofen, may be marked by the appearance of nausea, vomiting, abdominal pain, melena, impaired consciousness, respiratory depression, convulsions andkidney failure.
In case of overdose, gastric lavage and the required amount of activated charcoal should be taken. It is advisable to perform symptomatic treatment. The effect of ketoprofen on the digestive system is weakened by means that reduce the secretion of the gastric glands, for example, proton pump inhibitors and prostaglandins. In cases of kidney failure, hemodialysis is recommended.
Drug Interactions
Ketoprofen tablets - "Ketonal Duo", can weaken the effects of diuretics and antihypertensive drugs. In addition, it enhances the work of oral medications of the hypoglycemic and anticonvulsant type. Concomitant use with other non-steroidal anti-inflammatory drugs, salicylates, and in addition with ethanol may increase the risk of adverse effects on the digestive system.
Simultaneous use with such groups of drugs as anticoagulants, thrombolytics and antiplatelet agents increases the risk of bleeding. Simultaneous use with potassium, potassium-sparing diuretic, low molecular weight heparin and cyclosporins may increase the risk of hyperkalemia.
The presented drug increases the concentration of cardiac glycosides in plasma. It also contributes to an increase in slow calcium channel blockers, cyclosporins and methotrexates. Against its background, the toxicity of methotrexates and the nephrotoxicity of cyclosporins increase. The simultaneous use of the drug "Ketonal Duo" with probenecides significantly reduces the clearanceKetoprofen in the blood.
Special instructions for the use of the medication
Against the background of long-term use of non-steroidal anti-inflammatory drugs, it is necessary to monitor the state of the blood, as well as the function of the kidneys and liver, especially in elderly patients (over 65 years old).
In addition, care must be taken and blood pressure control when using ketoprofen in the treatment of patients with arterial hypertension and heart and vascular diseases. These pathologies can lead to fluid retention in the body. Like other non-steroidal anti-inflammatory drugs, ketoprofen may mask the symptoms of infectious diseases.

But, nevertheless, patients who notice non-standard effects while taking Ketonal Duo are advised to be careful when engaging in hazardous activities.

Ketonal Duo and alcohol
Concomitant use of alcohol and this drug may aggravate the therapeutic effect, increasing the risk of bleeding. There is also a high percentage of poisoning and liver damage.
Use in Pregnancy
The process of inhibition of prostaglandin synthesis can haveundesirable effects on the course of pregnancy, as well as on embryonic development. Data from an epidemiological study with the use of synthesis inhibitors in the early stages confirm an increase in the risk of spontaneous abortions and the development of heart disease.
Prescribing this drug to pregnant women during the first two trimesters is allowed only in situations where the benefits to the woman's he alth justify the likely risk to the fetus.
Ketoprofen is completely contraindicated for pregnant women in the third trimester due to the possibility of developing weakness in the activity of the uterus during childbirth.
