DESCRIPTION
Methocarbamol tablets USP a carbamate derivative of guaifenesin, is a
central nervous
system (CNS) depressant with sedative and musculoskeletal relaxant
properties.
The chemical name of methocarbamol is
3-(2-methoxyphenoxy)-1,2-propanediol 1-
carbamate and has the empirical formula C
H
NO
. Its molecular weight is 241.24.
The structural formula is shown below.
Methocarbamol is a white powder, sparingly soluble in water and
chloroform, soluble in
alcohol (only with heating) and propylene glycol, and insoluble in
benzene and n-hexane.
Methocarbamol tablets USP are available as 500 mg and 750 mg tablets
for oral
administration. Methocarbamol tablets USP 500 mg and 750 mg contain
the following
inactive ingredients: sodium lauryl sulfate, sodium starch glycolate,
povidone K 90,
polyethylene glycol, magnesium stearate, colloidal silicon dioxide,
low substituted
hydroxypropyl cellulose and stearic acid.
CLINICAL PHARMACOLOGY
The mechanism of action of methocarbamol in humans has not been
established, but
may be due to general central nervous system (CNS) depression. It has
no direct action
on the contractile mechanism of striated muscle, the motor end plate
or the nerve fiber.
PHARMACOKINETICS
In healthy volunteers, the plasma clearance of methocarbamol ranges
between 0.20 and
0.80 L/h/kg, the mean plasma elimination half-life ranges between 1
and 2 hours, and the
11
15
5
plasma protein binding ranges between 46% and 50%.
Methocarbamol is metabolized via dealkylation and hydroxylation.
Conjugation of
methocarbamol also is likely. Essentially all methocarbamol
metabolites are eliminated in
the urine. Small amounts of unchanged methocarbamol also are excreted
in the urine.
SPECIAL POPULATIONS
_Elderly_
The mean (±SD) elimination half-life of methocarbamol in elderly
healthy volunteers
(mean (±SD) age, 69 (±4) years) was slightly prolonged compared to a
younger (mean
(±SD) age, 53.3 (±8.8) years),
