THERAPEUTIC CLASSIFICATION
Combination Analgesic
ACTION AND CLINICAL PHARMACOLOGY
Pharmacologically, FIORINAL
®
(ASA-caffeine-butalbital) combines the analgesic properties of
acetylsalicylic acid (ASA) with the anxiolytic and muscle relaxant
properties of butalbital.
PHARMACOKINETICS:
The behaviour of the individual components is described below.
_ACETYLSALICYLIC ACID (ASA) _
ASA
is
a
salicylate
that
binds
to
the
cyclooxygenase
enzyme
leading
to
a
reduction
in
prostaglandin activity. The systemic availability of ASA after an oral
dose is highly dependent
on the dosage form, the presence of food, the gastric emptying time,
gastric pH, antacids,
buffering agents, and particle size. These factors affect not
necessarily the extent of absorption of
total salicylates but more the stability of ASA prior to absorption.
During the absorption process and after absorption, ASA is mainly
hydrolyzed to salicylic acid
and distributed to all body tissues and fluids, including fetal
tissues, breast milk, and the central
nervous system (CNS). Highest concentrations are found in plasma,
liver, renal cortex, heart, and
lung. In plasma, about 50% - 80% of the salicylic acid and its
metabolites are loosely bound to
plasma proteins.

The clearance of total salicylates is subject to saturable kinetics;
however, first-order elimination
kinetics are still a good approximation for doses up to 650 mg. The
plasma half-life for ASA is
about 12 minutes and for salicylic acid and/or total salicylates is
about 3 hours.
The elimination of therapeutic doses is through the kidneys
