The drug typically starts taking effect within 15 minutes and can last up to 16 hours depending on factors such as site of administration and dosage. [ 1 ] Levobupivacaine was designed, in the late 1970s, to be a safer and more effective alternative to bupivacaine, which had been associated with a higher risk of cardiotoxicity.
Bupivacaine is contraindicated in patients with known hypersensitivity reactions to bupivacaine or amino-amide anesthetics. It is also contraindicated in obstetrical paracervical blocks and intravenous regional anaesthesia because of potential risk of tourniquet failure and systemic absorption of the drug and subsequent cardiac arrest. The 0.75 ...
A mixture of 1 part 2% lidocaine with 3 parts 0.5% bupivacaine provides 0.5% lidocaine and 0.375% bupivacaine. This has the advantages of immediate anesthesia with lidocaine during injection to minimize injection pain while providing a longer duration of action with a lowered concentration of bupivacaine.

Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
However, new data suggested both ropivacaine (1.2-1.8 mg/kg in 40ml) and levobupivacaine (40 ml of 0.125% solution) can be used, because they have less cardiovascular and central nervous system toxicity than racemic bupivacaine. [2]
4-Aminopyridine is also used under the trade name Avitrol as 0.5% or 1% in bird control bait. It causes convulsions and, infrequently, death, depending on dosage. [18] The manufacturer says the proper dose should cause epileptic-like convulsions which cause the poisoned birds to emit distress calls resulting in the flock leaving the site; if the dose was sub-lethal, the birds will recover ...
