DESCRIPTION
Methocarbamol tablets, USP, a carbamate derivative of guaifenesin, are
a central nervous system (CNS)
depressant with sedative and musculoskeletal relaxant properties.
The chemical name of methocarbamol is
3-(2-meth-oxyphenoxy)-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: povidone,
sodium starch glycolate and magnesium stearate.
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 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.

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),
healthy population (1.5 (± 0.4) hours versus 1.1 (± 0.27) hours,
respectively). The fraction of bound
