Epidural administration of Ropivacaine hydrochloride monohydrate 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. Ropivacaine hydrochloride monohydrate inhibits pressure-induced increases in filtration coefficient (Kf) without affecting pulmonary artery pressure (Ppa), pulmonary capillary pressures (Ppc), and zonal characteristics (ZC). Ropivacaine hydrochloride monohydrate 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. Ropivacaine hydrochloride monohydrate inhibits pressure-induced NO production as evidenced by decreased lung nitro-tyrosine content when compared to hypertensive lungs.
