Note: This preparation should be prepared in a laminar
airflow hood in a cleanroom or via isolation barrier technology
by a validated aseptic compounding pharmacist using strict aseptic
technique. This is a high-risk preparation.
1. Calculate the required quantity of each ingredient
for the total amount to be prepared.
2. Accurately weigh and/or measure each ingredient.
3. Dissolve the tramadol hydrochloride and sodium
acetate in sufficient sterile water for injection to volume and
mix well.
4. Filter through sterile 0.220 -µm filters
into sterile single-use vials or syringes.
5. Package and label.

QUALITY CONTROL
Quality-control assessment can include weight/volume, physical
observation, pH, specific gravity, osmolality, assay, color, clarity,
particulate matter, sterility and pyrogenicity.2,3
DISCUSSION
Tramadol is an opioid analgesic with noradrenergic and serotonergic
properties that may contribute to its analgesic activity. It is
a centrally active analgesic acting apparently by selective activity
at the µ-receptor. Tt is used in the treatment of moderate-to-scvere
pain. It can be administered orally, reetally, intravenously and
intramuscularly.4
Tramadol hydrochloride (C^sub 16^H^sub 25^NO^sub 2^, MW 299.84)
occurs as an odorless, white to off-white crystalline powder that
is readily soluble in water and ethanol. It has a pKa of 9.41
and has a water: octanol partition coefficient of 1.35 at pH 7.
Sodium acetate (CH^sub 3^CO^sub 2^Na, MW 82.03, anhydrous; CH^sub
3^CO^sub 2^Na3H^sub 2^O, MW 136.08, trihydrate) occurs as colorless,
transparent crystals or as a granular, crystalline powder. It
is either odorless or may have a faint, acetous odor. The trihydrate
will effloresce in warm, dry air and it melts at about 60°C.
It is soluble in water (1 g in 0.8 mL) and alcohol (l g in 19
mL). It is often used as a component in a sodium acetatc:acetic
acid buffer.
Sterile water for injection is water for injection that has been
sterilized and suitably packaged; it contains no added substance.
Water for injection is water purified by distillation or by reverse
osmosis and contains no added substances. Note that water for
injection is not prepared by an ion-exchange process. Water is
used to describe potable water from a public water supply that
is suitable for drinking and is the beginning point of the official
waters. It is a clear, colorless, odorless and tasteless liquid.
Purified water is water that is obtained by distillation, ion
exchange, reverse osmosis or some other suitable process. Water
has a specific gravity of 0.9971 at room temperature, a melting
point at 0°C and a boiling point at 100°C. It is miscible
with most polar solvents and is chemically stable in all physical
states (ice, liquid and steam).1'6
