    Lidocaine Hydrochloride, USP is chemically designated 2-(Diethylamino)-2’,6’-acetoxylidide monohydrochloride monohydrate, a white powder freely soluble in water. The molecular formula is C14H22N2O• HCl •H2O. The molecular weight is 288.82. It has the following structural formula:

    The semi-rigid vial used for the plastic vials is fabricated from a specially formulated polyolefin. It is a copolymer of ethylene and propylene. The safety of the plastic has been confirmed by tests in animals according to USP biological standards for plastic containers. The container requires no vapor barrier to maintain the proper drug concentration.

    The plastic syringe is molded from a specially formulated polypropylene. Water permeates from inside the container at an extremely slow rate which will have an insignificant effect on solution concentration over the expected shelf life. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the syringe material.
