Dear colleagues, let me
introduce my presentation,
Dissolution Testing:
Methodology Development.
My name is Igor Shohin.
I'm a Doctor of
Pharmaceutical Sciences,
CEO of LLC Center of
Pharmaceutical Analytics.
0:20
So let's start our talk
with regulatory documents,
which regulate all issues about
dissolution testing
methods development.
The main document is
USP Monograph 1092
the dissolution procedure:
development and validation.
It should be noted that
this monograph was
completely rewritten
several years ago,
so this monograph is really
actual and important.
That second USP monograph,
which is required
for this topic is
assessment of solid oral
drug products performance
and interchangeability,
bioavailability,
bioequivalence, and dissolution.
And also, I would like to
mention two FDA guidances.
The first one is
dissolution testing of
immediate-release solid
oral dosage forms,
and the second is
dissolution testing
and acceptance criteria for
immediate-release solid
oral dosage forms from
drug products containing high
solubility drug substances.
I would like to mention that
the first FDA guidance
seems to be old, 1997.
But it is still actual
and very important.
