DESCRIPTION
Megestrol Acetate Oral Suspension, USP contains megestrol acetate, a
synthetic
derivative of the steroid hormone, progesterone. Megestrol acetate is
a white, crystalline
solid chemically designated as
17-Hydroxy-6-methylpregna-4,6-diene-3,20-dione
acetate. Solubility at 37°C in water is 2 mcg per mL, solubility in
plasma is 24 mcg per
mL. Its molecular weight is 384.52.
The chemical formula is C
H
O and the structural formula is represented as follows:
MEGESTROL ACETATE, USP
Megestrol acetate oral suspension is supplied as an oral suspension
containing 40 mg of
micronized megestrol acetate per mL.
Megestrol acetate oral suspension contains the following inactive
ingredients: alcohol
(max 0.06% v/v from flavor), artificial lime flavor, citric acid
monohydrate, docusate
sodium, glycerin, natural and artificial lemon flavor, purified water,
sodium benzoate,
sodium citrate dihydrate, sucrose and xanthan gum.
Megestrol acetate oral suspension, 40 mg/mL complies with USP
Dissolution Test 2.
CLINICAL PHARMACOLOGY
The precise mechanism by which megestrol acetate produces effects in
anorexia and
cachexia is unknown at the present time.
There are several analytical methods used to estimate megestrol
acetate plasma
concentrations, including gas chromatography-mass fragmentography
(GC-MF), high
24
32

pressure liquid chromatography (HPLC) and radioimmunoassay (RIA). The
GC-MF and
HPLC methods are specific for megestrol acetate and yield equivalent
concentrations.
The RIA method reacts to megestrol acetate metabolites and is,
therefore, nonspecific
and indicates higher concentrations than the GC-MF and HPLC methods.
Plasma
concentrations are dependent, not only on the method used, but also on
intestinal and
hepatic inactivation of the drug, which may be affected by factors
such as intestinal
tract motility, intestinal bacteria, antibiotics administered, body
weight, diet and liver
function.
