Description of dosage form

Round, flat tablets of white color, on one side engraving "ALKA SELTZER", in a convex circle around the perimeter; on the other is a chamfer.

pharmachologic effect

Pharmacological action - anti-inflammatory, antipyretic, antiaggregational, analgesic, antacid.

Pharmacodynamics

Combined drug, the effect of which is due to its constituent components.

Acetylsalicylic acid has an analgesic, antipyretic, anti-inflammatory effect, which is due to inhibition of COX enzymes involved in the synthesis of PG. Acetylsalicylic acid inhibits platelet aggregation by blocking the synthesis of thromboxane A2.

Sodium carbonate neutralizes free hydrochloric acid in the stomach, which reduces the irritant effect of the drug.

Citric acid promotes a faster absorption of the drug.

Indication of the drug Alka-Seltzer

symptomatic treatment of pain syndrome - headache (including after excessive consumption of alcohol), toothache, sore throat, back and muscle pain, joint pain, menstruation pain;

elevated body temperature for colds and other infectious-inflammatory diseases (in adults and children over 15 years old).

Contraindications

hypersensitivity to acetylsalicylic acid and other NSAIDs or other components of the drug;

erosive and ulcerative lesions of the gastrointestinal tract (in the phase of exacerbation);

hemorrhagic diathesis;

combined use of methotrexate in a dose of 15 mg per week or more;

asthma caused by the intake of salicylates or other NSAIDs;

pregnancy (I and III trimester);

the period of breastfeeding;

children under 15 with ARI caused by viral infections, because of the risk of developing Reye's syndrome (encephalopathy and acute fatty liver disease with acute development of liver failure).

Carefully:

concomitant therapy with anticoagulants;

gout;

peptic ulcer of stomach and / or duodenum (in the anamnesis), including chronic or recurrent ulcer disease, or episodes of gastrointestinal bleeding;

renal and / or liver failure;

deficiency of glucose-6-phosphate dehydrogenase.

pregnancy and lactation

Contraindicated in I and III trimesters of pregnancy.

If you need to use the drug during lactation, breastfeeding should be discontinued.

Side effects

Sometimes it is possible:

From the gastrointestinal tract: abdominal pain, heartburn, nausea, vomiting, obvious (vomiting with blood, tarry stool) or hidden signs of gastrointestinal bleeding, which can lead to iron deficiency anemia, erosive-ulcerative lesions (in including perforations) GIT, isolated cases - violations of the liver (increased liver transaminases).

From the hemopoietic system: increased risk of bleeding, which is a consequence of the effect of acetylsalicylic acid on platelet aggregation.

Allergic reactions: skin rash, anaphylactic reactions, bronchospasm, Quincke's edema.

When such symptoms appear, it is recommended to stop taking the drug and immediately consult a doctor.

Interaction

Joint application:

- with methotrexate at a dose of 15 mg per week or more: the hemolytic cytotoxicity of methotrexate is increased (decreased renal clearance of methotrexate and methotrexate is replaced by salicylates due to blood plasma proteins);

- with anticoagulants, for example heparin: the risk of bleeding increases due to the inhibition of platelet function, damage to the gastrointestinal mucosa, the displacement of anticoagulants (oral) from the connection with plasma proteins;

with other NSAIDs, as well as with high doses of salicylates (3 g per day or more): as a result of synergistic interaction, the risk of ulceration and bleeding increases;

- with uricosurates, for example benzbromarone: reduces the uricosuric effect;

- with digoxin: the concentration of digoxin is increased due to decreased renal excretion;

- with antidiabetic drugs, for example insulin: the hypoglycemic effect of antidiabetic drugs increases due to hypoglycemic action of acetylsalicylic acid;

- with preparations of thrombolytics group: the risk of bleeding increases;

- with diuretics at a dose of 3 mg per day or more: glomerular filtration decreases due to a reduction in the synthesis of PG;

- with systemic SCS, excluding hydrocortisone, used as a substitute therapy for Addison's disease: with the use of GCS, the level of salicylates in the blood decreases by increasing the excretion of the latter;

- with ACE inhibitors: at a dose of 3 g per day and more glomerular filtration is reduced by inhibition of PG and, as a consequence, the antihypertensive effect decreases;

- with valproic acid: the toxicity of valproic acid is increased;

- with ethanol: the risk of damaging effects on the gastrointestinal mucosa increases and the bleeding time increases.

Dosing and Administration

Inside, previously dissolved in a glass of water.

Adults and children over 15 years of age - 1 table. up to 6 times a day. For severe pain and high fever - 2-3 tablets; the maximum daily dose should not exceed 9 tablets. (3 g).

The interval between doses of the drug should be at least 4 hours. Regular adherence to the regimen of taking the drug avoids a sharp increase in temperature and reduces the intensity of the pain syndrome.

The duration of treatment (without consulting a doctor) should not exceed 5 days when prescribed as an anesthetic and more than 3 days - as an antipyretic.

Overdose

Symptoms: with an overdose of moderate severity - nausea, vomiting, tinnitus, hearing loss, headache, dizziness and confusion. These symptoms occur with a decrease in the dose of the drug.

Severe overdose: fever, hyperventilation, ketosis, respiratory alkalosis, metabolic acidosis, coma, cardiogenic shock, respiratory failure, severe hypoglycemia.

Treatment: symptomatic therapy, hospitalization, lavage, the use of activated charcoal, monitoring of acid-base balance, alkaline diuresis, in order to obtain a urine pH between 7.5-8 (forced alkaline diuresis is achieved if the concentration of salicylate in the blood plasma is more than 500 mg / l - (3.6 mmol / l, in adults or 300 mg / l - 2.2 mmol / l, in children), hemodialysis, fluid loss compensation.

special instructions

Acetylsalicylic acid can cause bronchospasm, an attack of bronchial asthma or other hypersensitivity reactions.

Risk factors are the presence of bronchial asthma, polyps of the nose, fever, chronic bronchopulmonary diseases, cases of allergy in the history (allergic rhinitis, rashes on the skin).

Acetylsalicylic acid can increase the tendency to bleeding, which is due to its inhibitory effect on platelet aggregation. This should be taken into account when necessary surgical interventions, including such minor interventions as tooth extraction. Before surgery, to reduce bleeding during surgery and in the post-operation period, you should cancel taking the drug for 5-7 days and inform the doctor.

If you need to use the drug during lactation, breastfeeding should be discontinued.

Children should not be prescribed drugs containing acetylsalicylic acid, because in the case of a viral infection, the risk of developing Reye syndrome increases. Symptoms of Reye's syndrome include prolonged vomiting, acute encephalopathy, and enlargement of the liver.

In the treatment of vascular diseases, the daily dose of acetylsalicylic acid is 75 to 300 mg.

Acetylsalicylic acid reduces the excretion of uric acid from the body, which can cause an acute attack of gout in predisposed patients.

In one effervescent tablet of the drug Alka-Seltzer contains 445 mg of sodium, which should be considered in a diet with controlled sodium intake.

There was no evidence of the effect of drug administration on vehicle management and other mechanisms.
