What is Ampicillin?

Ampicillin, a drug popular for many years, is an effective antibiotic. Despite the fact that new drugs have appeared, it is still in demand by doctors and patients. This semi-synthetic penicillin antibiotic is effective against many bacteria, and it helps better than others from sepsis and purulent infection. Not everyone knows exactly why Ampicillin helps, although its low price and availability in pharmacies make it one of the most purchased drugs. Many patients prescribe it for themselves, which, of course, should not be done. The use of Ampicillin should be strictly prescribed by the doctor, which takes into account the patient’s health status and features of his disease. You need to know exactly why Ampicillin helps, so as not to cause the development of superinfection, insensitive to antibiotics.

Pharmacological action of ampicillin

Ampicillin is active against gram-positive and some gram-negative microorganisms, as well as non-spore-forming bacteria, but is ineffective against penicillin-producing strains, as it is destroyed by penicillinase.

After ingestion, good absorption from the gastrointestinal tract is noted, the drug is not fed to the destruction in the acidic environment of the stomach, showing acid resistance. With parenteral administration, the amount of Ampicillin in blood plasma exceeds its content, which is formed when taken orally. The drug penetrates into most tissues and organs; its presence in therapeutic concentrations is noted in pleural, amniotic, synovial fluids, in bronchial secretions, saliva, and fetal tissues. For the most part, it is excreted in the urine and partially in the bile, it does not accumulate, which makes it possible to use it for a long time in high doses.

  • Bronchitis;
  • Pneumonia;
  • Abscess of the lung;
  • Tonsillitis;
  • Pharyngitis;
  • Peritonitis;
  • Meningitis;
  • Sepsis;
  • Rheumatism;
  • Urinary tract infections;
  • Intestinal infections;
  • Gynecological infections.
It is also prescribed if diseases cause other bacterial infections provoked by microorganisms sensitive to Ampicillin.

Methods of use and dosage

Before starting a course of treatment in the absence of a patient’s history of allergic reactions, skin tests for antibiotic tolerance should be performed. According to the instructions for use, Ampicillin is prescribed orally, intramuscularly and intravenously, in a stream and drip.

The daily dose for adults and children weighing more than 20 kg is 1-3 g, a single dose is 250-500 mg 4 times a day, with severe infection 1000-2000 mg every 3-4 hours.

The duration of treatment with Ampicillin tablets or its other forms is set individually depending on the severity of the disease and the sensitivity of the pathogen.

The course can last from 5-10 days to 2-3 weeks or more. After the disappearance of clinical signs, it is necessary to continue treatment for another 2-3 days, with a course of treatment more than 7 days, it is necessary to monitor liver and kidney function (at least once a week).

  • during sepsis therapy, a bacteriolysis reaction may develop;
  • if allergic reactions appear, treatment is canceled; debilitated patients may develop superinfection, which requires discontinuation of drug therapy;
  • for the prevention of candidiasis during treatment with Ampicillin, it is advisable to take Nystatin, Levorin, ascorbic acid and B vitamins.
