Ropivacaine (hydrochloride)

Ropivacaine hydrochloride is a potent?sodium channel?blocker and blocks impulse conduction via reversible inhibition of?sodium ion influx?in nerve fibrese^[1][2]. Ropivacaine is also an inhibitor of K_2P (two-pore domain potassium channel) TREK-1 with an IC₅₀ of 402.7 μM in COS-7 cell's membrane^[3]. Ropivacaine is widely used for neuropathic pain?management in vivo^[1]. IC50 & Target: IC50: sodium ion influx^[1]
IC50: 402.7 μM (TREK-1 in COS-7 cell's membrane)^[3] In Vivo: Epidural administration of Ropivacaine hydrochloride effectively blocks neuropathic pain (both mechanical allodynia and heat hyperalgesia) without induction of analgesic tolerance and significantly delays the development of neuropathic pain produced by peripheral nerve injury^[1].
Ropivacaine hydrochloride inhibits pressure-induced increases in filtration coefficient (Kf) without affecting pulmonary artery pressure (Ppa), pulmonary capillary pressures (Ppc), and zonal characteristics (ZC)^[2].
Ropivacaine hydrochloride prevents pressure-induced lung edema and associated hyperpermeability as evidence by maintaining PaO2, lung wet-to-dry ratio and plasma volume in levels similar to sham rats^[2].
Ropivacaine hydrochloride inhibits pressure-induced NO production as evidenced by decreased lung nitro-tyrosine content when compared to hypertensive lungs^[2].
