DESCRIPTION
BREVIBLOC (Esmolol Hydrochloride) is a beta adrenergic receptor blocker with a very short duration of action (elimination half-life is approximately 9 minutes). Esmolol hydrochloride is:
(±)-Methyl p-[2-hydroxy-3-(isopropylamino) propoxy] hydrocinnamate hydrochloride and has the following structure:
 |
Esmolol hydrochloride has the empirical formula C16H26NO4Cl and a molecular weight of 331.8. It has one asymmetric center and exists as an enantiomeric pair. Esmolol hydrochloride is a white to off-white crystalline powder. It is a relatively hydrophilic compound which is very soluble in water and freely soluble in alcohol. Its partition coefficient (octanol/water) at pH 7.0 is 0.42 compared to 17.0 for propranolol.
BREVIBLOC Injection Dosage Forms
All BREVIBLOC presentations are clear, colorless to light yellow, sterile, nonpyrogenic, iso-osmotic solutions of esmolol hydrochloride in sodium chloride. The formulations for BREVIBLOC PREMIXED Injection, BREVIBLOC DOUBLE STRENGTH PREMIXED Injection, and BREVIBLOC Injection are described in the table below:
 |
The calculated osmolarity of BREVIBLOC PREMIXED Injection and BREVIBLOC DOUBLE STRENGTH PREMIXED Injection is 312 mOsmol/L. The 250 mL and 100 mL bags are non-latex, non-PVC INTRAVIA bags with dual PVC ports. The INTRAVIA bags are manufactured from a specially designed multilayer plastic (PL 2408). Solutions in contact with the plastic container leach out certain chemical compounds from the plastic in very small amounts; however, biological testing was supportive of the safety of the plastic container materials.
