Is 1cc of carbocaine the same as 1cc of lidocaine?

Answer 1

It depends on what they are used for and how. Carbocaine (mepivacaine) and lidocaine are of the same drug class but their metabolism and half-life (and therefore effects) may differ, at least in some situations.

For example, for regional intravenous anesthesia, mepivacaine appears to provide more effective and durable anesthesia according to this article  http://bja.oxfordjournals.org/content/88/4/516.full
