Sensorcaine (bupivacaine hci injections) ® (bupivacaine HCl) injections are sterile isotonic solutions
that contain a local anesthetic agent with and without epinephrine (as bitartrate)
1:200,000 and are administered parenterally by injection. See INDICATIONS
AND USAGE for specific uses. Solutions of bupivacaine HCl may be autoclaved
if they do not contain epinephrine.
Sensorcaine (bupivacaine hci injections) injections contain bupivacaine HCl which is
chemically designated as 2-piperidinecarboxamide, 1-butyl-N-(2,6- dimethylphenyl)-,
monohydrochloride, monohydrate and has the following structure:
Epinephrine is (-)-3,4-Dihydroxy-α
[(methylamino)methyl] benzyl alcohol. It has the following structural formula:
The pKa of bupivacaine (8.1) is similar to that of lidocaine
(7.86). However, bupivacaine possesses a greater degree of lipid solubility and
is protein bound to a greater extent than lidocaine.
Bupivacaine is related chemically and pharmacologically to
the aminoacyl local anesthetics. It is a homologue of mepivacaine and is chemically
related to lidocaine. All three of these anesthetics contain an amide linkage
between the aromatic nucleus and the amino or piperidine group. They differ in
this respect from the procaine-type local anesthetics, which have an ester
Dosage forms listed as Sensorcaine (bupivacaine hci injections) -MPF indicates single
dose solutions that are Methyl Paraben Free (MPF).
Sensorcaine (bupivacaine hci injections) -MPF is a sterile isotonic solution
containing sodium chloride. Sensorcaine (bupivacaine hci injections) in multiple dose vials, each mL also
contains 1 mg methylparaben as antiseptic preservative. The pH of these
solutions is adjusted to between 4.0 and 6.5 with sodium hydroxide and/ or
Sensorcaine (bupivacaine hci injections) -MPF with Epinephrine 1:200,000 (as
bitartrate) is a sterile isotonic solution containing sodium chloride. Each mL contains
bupivacaine hydrochloride and 0.005 mg epinephrine, with 0.5 mg sodium
metabisulfite as an antioxidant and 0.2 mg citric acid (anhydrous) as
stabilizer. Sensorcaine (bupivacaine hci injections) with Epinephrine 1:200,000 (as bitartrate) in
multiple dose vials, each mL also contains 1 mg methylparaben as antiseptic
preservative. The pH of these solutions is adjusted to between 3.3 to 5.5 with
sodium hydroxide and/ or hydrochloric acid. Filled under nitrogen.
Note: The user should have an appreciation and awareness of the formulations
and their intended uses. (See DOSAGE AND ADMINISTRATION.)
What are the possible side effects of bupivacaine (Marcaine HCl, Marcaine Spinal, Sensorcaine, Sensorcaine-MPF)?
Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.
Tell your caregivers at once if you have any of these serious side effects:
- weak or shallow breathing;
- fast heart rate, gasping, feeling unusually hot;
- slow heart rate, weak pulse;
- feeling restless or anxious, ringing in the ears, metallic taste, speech problems, numbness or tingling around your mouth, tremors, feeling light-headed, or...
