(S)-Ropivacaine acts on the sodium channels in neuronal cells, blocking the conduction of nerve impulses. This results in a loss of sensation in the affected area, providing analgesic and anesthetic effects. (S)-Ropivacaine may act to cause decreases in neuronal excitability, calcium influx into the cell, and the release of neurotransmitters, such as glutamate and norepinephrine. It has been used in a variety of in vitro applications, including cell culture studies, enzyme assays, and receptor binding studies. These studies have found anti-inflammatory, anticonvulsant, antinociceptive, and anti-allodynic effects of (S)-Ropivacaine.
