Excipients q.s.



Ampicillin is semi-synthetic Penicillin, a broad spectrum antibiotic effective against a wide range of Gram-positive and Gram-negative organisms. It is stable in the presence of gastric acid and is well absorbed from G.I.T. Ampicillin is excreted largely unchanged in the urine and is inactivated by Penicillinase producing organisms.


Clinical Pharmacology

Ampicillin is bactericidal at low concentrations and is clinically effective not only against the gram-positive organisms usually susceptible to penicillin G but also against a variety of gram-negative organisms. It is stable in the presence of gastric acid and is well absorbed from the gastrointestinal tract. It diffuses readily into most body tissues and fluids; however, penetration into the cerebrospinal fluid and brain occurs only with meningeal inflammation. Ampicillin is excreted largely unchanged in the urine; its excretion can be delayed by concurrent administration of probenecid which inhibits the renal tubular secretion of ampicillin in blood serum, ampicillin is the least bound of all the penicillins, an average of about 20 percent of the drug is bound to the plasma proteins as compared to 60 to 90 percent of the other penicillin’s. The average peak serum level for a 250 mg dose of ampicillin trihydrate for oral suspension is approximatety 2.3 mcg/mL.


Indication and Usage

Ampicillin is part of a group of antibiotics called penicillin and is used to treat different types of infections caused by bacteria such as ear infections, bladder infections, pneumonia, gonorrhea, and E. coli or Salmonella infections.



A history of a previous hypersensitivity reaction to any of the penicillins is a contraindication. Ampicillin is also contraindicated in infections caused by penicillinase-producing organisms.


Drug Interactions

When administered concurrently, the following drugs may interact with ampicillin.

Allopurinol: Increased possibility of skin rash, particularly in hyperuricemic patients may occur.

Bacteriostatic Antibiotics: Chloramphenicol, erythromycins, sulfonamides, or tetracyclines may interfere with the bactericidal effect of penicillins. This has been demonstrated in view, however, the clinical significance of this interaction is not well documented.

Oral Contraceptives: May be less effective and increased breakthrough bleeding may occur.

Probenecid: May decrease renal tubular secretion of ampicillin resulting in increased blood levels and/or ampicillin toxicity.



Caution should be exercised in patients with history of kidney or liver disease, any allergy, asthma, blood disease, intestinal inflammation, stomach problems, hay fever, who are taking other medications, children, during pregnancy and breastfeeding.

Use in pregnancy

Teratogenic effects: Category B

Reproduction studies in animals have revealed no evidence of impaired fertility or harm to the fetus due to penicillin. There are, however no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, penicillin should be used during pregnancy only if clearly needed.


Nursing Mothers

Ampicillin-class antibiotics are excreted in milk. Ampicillin used by nursing mothers may lead to sensitization of infants; therefore, a decision should be made whether to discontinue nursing or to discontinue ampicillin, taking into account the importance of the drug to the mother.



Do not take Ampicillin Capsules if you allergic to penicillin, Ampicillin or any other drug. You should tell your health care provider if you are taking any other prescribed or over the counter drugs (especially antibiotics) like allopurinol, anticoagulants such as (warfarin and atenolol) oral contraceptives, probenecid, rifampin, sulfasalaszine and vitamins.

Tell your health care provider if you have or have had any kidney or liver diseases, allergies, asthma, blood disease; colitis, stomach problems or hay fever.

If you plan on having surgery (including dental) always inform your health care provider that you are taking Ampicillin Capsules. If you are pregnant or plan on becoming pregnant, discuss your options with your health care provider or pharmacist.
