Acetylcysteine

Overdose

Symptoms: acetylcysteine when taken at a dose of up to 500 mg / kg did not cause any symptoms of intoxication. With an erroneous or deliberate overdose, such phenomena as diarrhea, vomiting, stomach pain, heartburn and nausea can be observed. Children may experience sputum hypersecretion.

Treatment: symptomatic.

Shelf life

3 years

After reconstitution, the product must be administered immediately.

Contraindications

For all dosage forms

hypersensitivity to acetylcysteine or other components of the drug,

peptic ulcer of the stomach and duodenum in the acute stage,

hemoptysis, pulmonary hemorrhage,

pregnancy,

breastfeeding period,

children under 2 years of age.

For effervescent tablets, 100 mg, optional

lactase deficiency, lactose intolerance, glucose-galactose malabsorption.

With caution: a history of gastric and duodenal ulcer, bronchial asthma, obstructive bronchitis, hepatic and/or renal insufficiency, histamine intolerance (long-term use of the drug should be avoided, since acetylcysteine affects the metabolism of histamine and can lead to signs of intolerance, such as headache, vasomotor rhinitis, itching), esophageal varicose veins, adrenal diseases, arterial hypertension.

For granules for the preparation of the solution in addition

sucrose/isomaltase deficiency, fructose intolerance, glucose-galactose deficiency.

With caution: a history of gastric and duodenal ulcer, arterial hypertension, esophageal varicose veins, bronchial asthma, obstructive bronchitis, adrenal diseases, hepatic and/or renal insufficiency, histamine intolerance (long-term use of the drug should be avoided, since acetylcysteine affects the metabolism of histamine and can lead to signs of intolerance, such as headache, vasomotor rhinitis, itching).

For the syrup in addition

With caution: a history of gastric and duodenal ulcer, bronchial asthma, hepatic and / or renal insufficiency, histamine intolerance (long-term use of the drug should be avoided, since acetylcysteine affects the metabolism of histamine and can lead to signs of intolerance, such as headache, vasomotor rhinitis, itching), esophageal varicose veins, adrenal diseases, arterial hypertension.

Incompatibilities

For all dosage forms

With the simultaneous use of acetylcysteine and antitussive agents, due to the suppression of the cough reflex, sputum stagnation may occur. Therefore, such combinations should be selected with caution.

Concomitant administration of acetylcysteine with vasodilators and nitroglycerin may lead to an increase in the vasodilator effect.

When used simultaneously with oral antibiotics (including penicillins, tetracyclines, cephalosporins) , they may interact with the thiol group of acetylcysteine, which may lead to a decrease in their antibacterial activity. Therefore, the interval between taking antibiotics and acetylcysteine should be at least 2 hours (except for cefixime and loracarbene).

Upon contact with metals, rubber forms sulfides with a characteristic smell..

Undesirable effects

According to WHO, adverse reactions are classified according to their frequency of development as follows: very common (≥1/10), common (≥1/100, <1/10), infrequent (≥1/1000, <1/100), rare (≥1/10000, <1/1000), very rare (<1/10000), frequency unknown — according to available data, it was not possible to determine the frequency of occurrence.

Allergic reactions: infrequently-skin itching, rash, exanthema, urticaria, angioedema, decreased blood pressure, tachycardia, very rarely-anaphylactic reactions up to shock, Stevens-Johnson syndrome, toxic epidermal necrolysis (Lyell's syndrome).

From the respiratory system: rarely-shortness of breath, bronchospasm (mainly in patients with hyperreactivity of the bronchi in bronchial asthma).

From the gastrointestinal tract: infrequently-stomatitis, abdominal pain, nausea, vomiting, diarrhea, heartburn, dyspepsia (except syrup).

Acetylcysteine price

Average cost of Acetylcysteine 200 mg/ml per unit in online pharmacies is from 1.63$ to 3.65$, per pack from 55$ to 516$.

Preclinical safety data

Acute toxicity studies in rats and mice, by oral, intraperitoneal and intravenous administration showed acetylcysteine to be of low toxicity. LD50 values greater than 7 g / kg in mice and 6 g / kg in rats have been reported. Chronic toxicity studies with acetylcysteine in rats at doses up to 2000 mg/ kg/ day and dogs at doses up to 300 mg/ kg / day for periods up to 52 weeks demonstrate that acetylcysteine is well tolerated, even at higher doses. In reproductive toxicity studies in rats and rabbits, the oral administration of doses up to 2000 mg / kg / day did not show changes in reproductive capacity, teratogenic effects or peri/postnatal toxicity.

Pharmacodynamic properties

Acetylcysteine is a derivative of the amino acid cysteine. It has a mucolytic effect, facilitates the discharge of sputum due to a direct effect on the rheological properties of sputum. The effect is due to the ability to break the disulfide bonds of mucopolysaccharide chains and cause depolymerization of sputum mucoproteins, which leads to a decrease in its viscosity. The drug remains active in the presence of purulent sputum.

It has an antioxidant effect based on the ability of its reactive sulfhydryl groups (SH-groups) to bind to oxidative radicals and thus neutralize them.

In addition, acetylcysteine promotes the synthesis of glutathione, an important component of the antioxidant system and chemical detoxification of the body. The antioxidant effect of acetylcysteine increases the protection of cells from the damaging effects of free radical oxidation, which is characteristic of an intense inflammatory reaction.

With the prophylactic use of acetylcysteine, there is a decrease in the frequency and severity of exacerbations of bacterial etiology in patients with chronic bronchitis and cystic fibrosis.

Pharmacokinetic properties

The absorption is high. It is rapidly metabolized in the liver to form a pharmacologically active metabolite-cysteine, as well as diacetylcysteine, cystine and mixed disulfides. Oral bioavailability is 10% (due to the presence of a pronounced effect of the first passage through the liver). Tmax in the blood plasma is 1-3 hours. The bond with plasma proteins is 50%. It is excreted by the kidneys in the form of inactive metabolites (inorganic sulfates, diacetylcysteine). T1/2 it is about 1 h, impaired liver function leads to an elongation of the T1/2 up to 8 hours. Penetrates through the placental barrier. There are no data on the ability of acetylcysteine to penetrate the BBB and be excreted in breast milk.

Interaction with other medicinal products and other forms of interaction

Drug Interactions

Antitussive drugs and acetylcysteine should not be administered concomitantly because reducing the cough reflex may lead to a build-up of bronchial secretions.

Activated charcoal may reduce the effect of acetylcysteine.

It is advisable not to mix Acetylcysteine 200 mg Powder for Oral Solution with other medicinal products.

In vitro tests have shown that when cephalosporin antibiotics and acetylcysteine are mixed, there is a degree of antibiotic inactivation. It is precautionary to advise the administration of oral antibiotics at least two hours before or after acetylcysteine.

Concurrent administration of nitroglycerin and acetylcysteine causes significant hypotension and leads to temporal artery dilation with possible onset of headache.

If concurrent administration of nitroglycerin and acetylcysteine is required, patients should be monitored and warned for hypotension that can be severe and accompanied by a headache.
