6R)-6-[(R)-2-Amino-2-
phenylacetamido]-3,
3-dimethyl-7-oxo-4-this-l-azabicyclo[3.2.0]heptane-2-carbxylic acid
trihydrate. It

The molecular formula is C

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
