This is a broad-spectrum antibacterial bactericidal agent from the group of semisynthetic penicillins, obtained by acylation of 6-aminopenicillanic acid with an aminophenylacetic acid residue, it is acid resistant. It inhibits peptidoglycan polymerase and transpeptidase, prevents the formation of peptide bonds and disrupts the late stages of the synthesis of the cell wall of a dividing microorganism, which leads to a decrease in the osmotic resistance of the bacterial cell and causes its lysis.

Is it OK to drink alcohol while taking Ampicillin?

This is one of the most frequently asked questions.

The drug is excreted from the body in the urine, about 30% of the drug is metabolized by the liver. A patient combining ampicillin and alcohol should understand that alcohol will distort the pharmacological effect of the drug and the drug will become toxic. Ethanol changes the sensitivity of all organs, their cells and tissues to the action of the drug, making its effect unpredictable.

In the case when this drug and alcohol are simultaneously taken in a short period of time, the consequences for the liver can be extremely undesirable. Decay products are accumulated there, the metabolism is disrupted. The formation of proteins that neutralize the action of toxins is reduced, which adversely affects the liver and the body as a whole.

The use of this drug with alcohol is also contraindicated because it disrupts the functioning of liver enzymes that break down substances. This leads to an uncontrolled effect of the drug. When using the drug, it is recommended to regularly monitor liver functions since the body receives a large load as a result of taking the medicine.

When using the drug for the treatment of sepsis, a bacteriolysis reaction (the Yarish-Herxheimer reaction) may occur.

If allergic reactions occur during treatment, the drug should be discontinued and desensitizing therapy should be prescribed.

Weakened patients who have to use the drug for a long time may develop superinfection caused by ampicillin-resistant microorganisms.

To prevent the development of candidiasis due to antibiotic treatment, a patient should take nystatin or levorin, as well as B and C vitamins.
