Description

Pharmacotherapeutic group:Anallergic and “cold” remedy (analgesic non-narcotic + alpha-adrenomimetic + vitamin).

ATX code: N02BE51

Pharmacological properties

A combined remedy, the action of which is due to its constituent components.

Pharmacodynamics

Paracetamol is an analgesic and antipyretic. Its mechanism of action is thought to be the inhibition of prostaglandin synthesis, mainly in the central nervous system.

It has practically no effect on the synthesis of prostaglandins in the peripheral tissues, does not change the water-electrolyte metabolism and does not damage the mucous membrane of the gastro-intestinal tract. This property of paracetamol makes the drug particularly suitable for patients with a history of gastrointestinal diseases (e.g., patients with a history of gastrointestinal bleeding or elderly patients) or patients taking concomitant medication in which inhibition of peripheral prostaglandin synthesis may be undesirable.

Phenylephrine hydrochloride is a sympathomimetic agent aimed at stimulation of adrenoreceptors (mainly α-adrenoreceptors), which leads to reduction of nasal mucosal edema and facilitation of nasal breathing.

Ascorbic acid (vitamin C) replenishes the increased need for vitamin C during “colds” and flu, especially at the initial stages of the disease. The ingredients do not cause drowsiness or impair concentration.

Pharmacokinetics

Absorption and distribution

The absorption of paracetamol in the gastrointestinal tract is high. Time to reach maximum plasma concentration is 0.5-2 hours; maximum plasma concentration is 5-20 µg/ml. Binding with plasma proteins is 15%. It penetrates through the blood-brain barrier.

Phenylephrine hydrochloride is unevenly absorbed from the gastrointestinal tract. Maximum plasma concentrations are reached between 45 min and 2 h. There are no data on distribution.

Ascorbic acid is quickly absorbed from the gastrointestinal tract and distributed throughout the body. The binding to plasma proteins is 25%.

Metabolism

Paracetamol is metabolized mainly in the liver. 90-95 % by three main pathways: 80% undergo conjugation reactions with glucuronic acid and sulfates to form inactive metabolites; 17% undergo hydroxylation to form 8 active metabolites, which conjugate with glutathione to form already inactive metabolites. In case of glutathione deficiency these metabolites can block enzyme systems of hepatocytes and cause their necrosis. The CYP2E1 isoenzyme is also involved in metabolism of the drug.

Phenylephrine hydrochloride undergoes primary metabolism by monoamine oxidases in the intestine and liver. Thus, the bioavailability of phenylephrine is reduced with oral administration.

There are no data on ascorbic acid metabolism.

Elimation

Paracetamol is excreted by the kidneys as metabolites, mainly glucuronide and sulfate conjugates, less than 5% is excreted unchanged. The elimination half-life is 1-4 hours. In elderly patients the drug clearance is decreased and the half-life is prolonged, but no dose adjustment is required. Phenylephrine hydrochloride is excreted by the kidneys almost completely in the form of sulfate conjugates. The elimination period is 2-3 hours.

When administered in doses that exceed the body’s need for ascorbic acid, ascorbic acid is excreted by the kidneys as metabolites.

Indications

The drug is used as a temporary remedy for symptoms of “colds” and flu, including:

– fever;

– headache;

– chills;

– joint and muscle pain;

– sinus pain and congestion;

– sore throat.

Active ingredient

Paracetamol, phenylephrine, ascorbic acid

Composition

Effective ingredients:

Paracetamol – 750 mg,

Phenylephrine hydrochloride – 10 mg,

Ascorbic acid – 60 mg.

How to take, the dosage

For oral administration.

Do not exceed the recommended dose!

Have to use the lowest dose necessary to achieve an effect for the shortest possible treatment period!

The minimum interval between doses of Prostudox® should be at least 4 hours.

Pour the contents of 1 sachet into a mug, pour about 250 ml of hot water and mix thoroughly. If necessary, add cold water and sugar.

Adults and children over 12 years

1 sachet every 4-6 hours, but no more than 4 sachets per day. The maximum duration of use of the drug without consulting a physician should be no more than 5 days.

It is not recommended to use the drug as a antipyretic for more than 3 days without physician’s consultation.

The use with other paracetamol-containing agents, decongestants and agents for relief of symptoms of “colds” and flu, as well as with ethanol-containing agents and drinks is not recommended.

If symptoms persist while taking the drug, you should see your doctor.

If you exceed the recommended dose, seek medical attention immediately, even if you feel well, as there is a risk of delayed serious liver damage. Paracetamol overdose may cause hepatic and/or renal failure.

Special patient groups

Patients with impaired renal function

. Patients with impaired renal function should consult a physician before using Prostudox®. The limitations associated with the use of preparations containing this combination of active ingredients in patients with impaired renal function are mainly due to the paracetamol content of the drug.

Patients with hepatic impairment

Patients with hepatic impairment should consult their physician before using Prostudox®. The limitations associated with the use of preparations containing this combination of active ingredients in patients with impaired liver function are primarily due to the paracetamol content of the drug.

Interaction

Potentially clinically significant drug interactions are presented below (see sections “Contraindications” and “Cautions”).

Paracetamol when taken regularly for a long time increases the effect of indirect anticoagulants (warfarin and other coumarins), which increases the risk of bleeding. Episodic administration of a single dose of the drug has no significant effect on their effect.

The inducers of microsomal oxidation enzymes in the liver (barbiturates, diphenine, carbamazepine, rifampicin, zidovudine, phenytoin, ethanol, flumecinol, phenylbutazone and tricyclic antidepressants) increase the risk of hepatotoxic effect in overdose and concomitant use with paracetamol.

Microsomal oxidation inhibitors (cimetidine) reduce the risk of hepatotoxic effects.

Halothane increases the risk of ventricular arrhythmias.

Paracetamol reduces the effectiveness of diuretics and uricosuric drugs. Metoclopramide and domperidone increase, and colestyramine decreases the rate of absorption of paracetamol.

Paracetamol increases the effects of MAO inhibitors, sedatives, ethanol. Concomitant use of paracetamol and alcoholic beverages increases the risk of liver damage and acute pancreatitis.

Phenylephrine when taken with MAO inhibitors may lead to increased blood pressure.

Phenylephrine may decrease the effectiveness of beta-adrenal blockers and other hypotensive drugs (including such drugs as debrisoquine, guanethidine, reserpine, methyldopa) and may increase the risk of hypertension and cardiovascular events.

Tricyclic antidepressants (e.g., amitriptyline) increase the sympathomimetic effects of phenylephrine and may increase the risk of cardiovascular side effects. Concomitant use of halothane with phenylephrine increases the risk of ventricular arrhythmia. Phenylephrine reduces the hypotensive effect of guanethidine, which in turn increases the alpha-adrenergic stimulating activity of phenylephrine.

Antidepressants, antiparkinsonics, antipsychotics, phenothiazine derivatives increase the risk of urinary retention, dry mouth, constipation.

The concomitant use of glucocorticosteroids with phenylephrine increases the risk of glaucoma.

The concomitant use of digoxin and other cardiac glycosides may increase the risk of heart rhythm disturbances and heart attack.

The concomitant use of phenylephrine with sympathomimetic amines may increase the risk of cardiovascular side effects. Concomitant use of phenylephrine and ergot alkaloids (e.g., ergotamine and methysergide) may increase the risk of ergotism.

Ascorbic acid increases the risk of crystalluria when treated with salicylates and short-acting sulfonamides, slows renal excretion of acids, increases excretion of drugs that are alkaline (including alkaloids), and reduces the blood concentration of oral contraceptives.

Ethanol promotes the development of acute pancreatitis.

Myelotoxic drugs increase the manifestation of hematotoxicity of the drug.

Special Instructions

If no improvement is seen while taking the drug or if the first signs of overdose appear, even if there are no clear symptoms of poisoning, it is necessary to see a doctor immediately.

The drug contains paracetamol; it should not be taken together with other paracetamol-containing drugs, as well as non-opioid analgesics, NSAIDs (sodium metamisole, acetylsalicylic acid, ibuprofen etc.

To avoid toxic liver damage, the drug should not be combined with ethanol-containing drugs and beverages, and people prone to chronic alcohol consumption.

Companion liver disease increases the risk of further liver damage when taking the drug. There is a high risk of overdose when the drug is taken in patients with non-alcoholic cirrhosis.

Please tell your physician about the use of Prostudox® when you have uric acid and blood glucose tests, because the drug may interfere with the results of laboratory tests that measure glucose and uric acid concentrations.

Patients with glutathione deficiency due to eating disorders, cystic fibrosis, HIV infection, starvation, exhaustion, are prone to overdose, so precautions should be taken and it is recommended to consult a physician before taking the drug. There have been recorded cases of liver failure / liver function abnormalities in small overdoses of paracetamol (5 g or more) in patients with low glutathione levels, particularly in extremely emaciated patients with anorexia, chronic alcoholism, patients with low body mass index or sepsis.

The use of the drug in patients with low glutathione levels, e.g., in sepsis, may increase the risk of metabolic acidosis accompanied by symptoms of rapid, difficult breathing (shortness of breath, shortness of breath), nausea, vomiting, loss of appetite. If these symptoms occur simultaneously, you should see a doctor immediately.

Physician should be consulted before taking Prostudox® if any symptoms occur:

– if you are taking warfarin or other indirect blood thinning anticoagulants;

– If you are taking metoclopramide, domperidone (commonly used for nausea and vomiting), or colestyramine to lower blood cholesterol;

If you are on a low-sodium diet.

Influence on the ability to drive vehicles, mechanisms

The drug may cause dizziness. If dizziness occurs, it is not recommended to drive vehicles or operate machinery.

Overdose
Overdose
The drug should only be taken in the recommended doses!
If an overdose is suspected, even if you feel well, you should stop using the drug and see a doctor immediately, as there is a risk of delayed serious liver damage and hospitalization may be required.
An overdose is usually caused by paracetamol.
Paracetamol
Symptoms
.An overdose of paracetamol can lead to liver failure, which may require a liver transplant or death.
For 24 hours, pale skin, decreased appetite, nausea, vomiting, abdominal pain, sweating may occur. Clinical signs of liver damage usually develop within 24-48 hours and reach their maximum in 4-6 days. There may be signs of impaired glucose metabolism and metabolic acidosis. Toxic effects in adults are possible after ingestion of more than 10 g of paracetamol: increased activity of “hepatic” transaminases. Acute pancreatitis has been observed, usually with impaired liver function and liver toxicity. Acute renal failure with acute tubular necrosis, which is diagnosed by severe pain in the lumbar region, hematuria and proteinuria, may develop without severe liver dysfunction. There have been reports of cases of cardiac arrhythmias in paracetamol overdose.
Ingestion of 5 g or more of paracetamol may lead to liver damage in patients with the following risk factors:
– prolonged treatment with carbamazepine, phenobarbital, phenytoin, primidone, rifampicin, St. John’s wort preparations, or other drugs that stimulate liver enzymes;
– regular consumption of alcohol in excessive amounts;
– glutathione deficiency (due to nutritional disorders, cystic fibrosis, HIV infection, starvation, exhaustion).
At the first sign of overdose, seek immediate medical attention, even if there are no clear symptoms of poisoning.
Treatment
In the first hours after a suspected overdose, oral administration of activated charcoal is appropriate. Four or more hours after a suspected overdose, plasma paracetamol concentrations should be determined (earlier determination of paracetamol concentrations may be unreliable). Treatment with acetylcysteine can be carried out up to 24 hours after paracetamol administration, but the maximum hepatoprotective effect can be obtained in the first 8 hours after overdose. After that, the effectiveness of the antidote drops sharply. If necessary, acetylcysteine may be administered intravenously. In the absence of vomiting, oral administration of methionine is an alternative option (in the absence of rapid inpatient care). Treatment of patients with severe liver dysfunction 24 hours after paracetamol administration should be done in conjunction with specialists from a toxicology center or a specialized liver disease unit.
Phenylephrine
Symptoms
./p>
The symptoms of phenylephrine overdose are similar to the manifestations of side effects. In addition: irritability, headache, dizziness, insomnia, increased excitability, increased blood pressure, nausea, vomiting, reflex bradycardia. In severe cases of overdose, hallucinations, confusion, seizures, arrhythmia may develop. It should be taken into account that the appearance of clinically significant symptoms of phenylephrine overdose when taking the drug is always associated with severe liver damage against overdose of paracetamol.
Treatment
Symptomatic therapy, in severe arterial hypertension the use of alpha-adrenoblockers such as phentolamine.
Ascorbic acid
Symptoms
. High doses of ascorbic acid (more than 3000 mg) may cause temporary osmotic diarrhea and gastrointestinal disturbances such as nausea and stomach discomfort. It should be taken into account that the appearance of clinically significant symptoms of ascorbic acid overdose when taking the drug is always associated with severe liver damage in the background of paracetamol overdose.
Treatment
Symptomatic, forced diuresis.

Pregnancy use
Pregnancy use
The drug is contraindicated in pregnancy and during breast-feeding.
