AI summarySynthesized from FDA + DailyMed + ClinicalTrials.gov data
Marcaine Hydrochloride with Epinephrine Preservative Free is a local anesthetic injection containing bupivacaine and epinephrine used for regional anesthesia, analgesia, and pain control during surgical, dental, diagnostic, therapeutic, and obstetrical procedures. It works by blocking nerve impulses through increased electrical excitation threshold and slowed nerve impulse propagation. The epinephrine acts as a vasoconstrictor to slow systemic absorption and prolong anesthetic effect.
LOE Approaching
Product approaching loss of exclusivity with moderate competitive pressure (30% intensity) suggests defensive commercial strategy and potential team consolidation.
Mechanism of Action
impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination, and conduction…
