solution may be prepared by mixing the contents of a suitable
number of vials and diluting 25 ml with particle-free water or with
an appropriate particle-free solvent when particle-free water is
not suitable. Small volume parenterals having a volume of 25 ml
or more may be tested individually.
b. Proceed with the test as delineated in USP <788> recording the
number of particles that are equal to or greater than 10µm and
the number of particles that are equal to or greater than 25µm.
As an alternative a partial membrane filter count and
determination of the total filter count by calculation is allowed.
Once a particle count is determined the mean number of
particles for the examined specimen is calculated. Note: For test
specimens which are covered by USP <789> the number of
particles that are equal to or greater than 50µm must also be
counted and a calculated average reported.
c. The calculated data is evaluated according to USP <788> or
USP <789> considering the solution type and the container
volume.
11. Chapter 7: Antibiotic Potency Testing
A. General Information
USP <81> Antibiotics- Microbial Assays, is the primary reference for bioassay
of human antibiotic potency testing. Prior to testing, the current USP <81> and
respective drug monograph should be reviewed for testing requirements,
acceptance criteria and applicability. USP <81> lists specific human antibiotics
to be tested for microbial potency; this list can change at any time. All other
human antibiotics not listed in USP <81> are typically tested using CFR 21
