THERAPEUTIC CLASSIFICATION
Angiotensin II AT
1
Receptor Blocker
ACTION AND CLINICAL PHARMACOLOGY MECHANISM OF ACTION
Irbesartan antagonizes angiotensin II by blocking AT
1
receptors.
Angiotensin II is the primary vasoactive hormone in the
renin-angiotensin system. Its effects include
vasoconstriction and the stimulation of aldosterone secretion by the
adrenal cortex.
Irbesartan blocks the vasoconstrictor and aldosterone-secreting
effects of angiotensin II by
selectively blocking in a non competitive manner the binding of
angiotensin II to the AT
1
receptor found in many tissues. Irbesartan has no agonist activity at
the AT
1
receptor. AT
2
receptors have been found in many tissues, but to date they have not
been associated with
cardiovascular homeostasis. Irbesartan has essentially no affinity for
the AT
2
receptors.
Irbesartan does not inhibit angiotensin converting enzyme, also known
as kinase II, the enzyme
that converts angiotensin I to angiotensin II and degrades bradykinin,
nor does it affect renin or
other
hormone
receptors
or
ion
channels
involved
in
cardiovascular
regulation
of
blood
pressure and sodium homeostasis.
PHARMACOKINETICS
_ABSORPTION: _
Irbesartan is an orally active agent. The oral absorption of
irbesartan is rapid and
complete with an average absolute bioavailability of 60% - 80%.
Irbesartan exhibits linear
pharmacokinetics over the therapeutic dose range with an average
terminal elimination half-life
of 11-15 hours. Following oral administration, peak plasma
concentrations are attained at 1.5-2
hours after dosing. Steady-state concentrations are achieved within 3
days.
_DISTRIBUTION: _
Irbesartan is approximately 96% protein-bound in the pl
