Wikipedia
Local anesthetic (LA) is a medication that causes reversible absence of pain sensation, although other senses are often affected as well. Also, when it is used on specific nerve pathways ( local anesthetic nerve block), paralysis (loss of muscle power) can be achieved as well.
Clinical local anesthetics belong to one of two classes: aminoamide and aminoester local anesthetics. Synthetic local anesthetics are structurally related to cocaine. They differ from cocaine mainly in that they have a very low abuse potential and do not produce hypertension or (with few exceptions) vasoconstriction.
Local anesthetics are used in various techniques of local anesthesia such as:
- Topical anesthesia (surface)
- Topical administration of cream, gel, ointment, liquid, spray &c of anaesthetic dissolved in DMSO or other solvents/carriers for deeper absorption
- Infiltration
- Plexus block
- Epidural (extradural) block
- Spinal anesthesia (subarachnoid block)
- Iontophoresis
