Ropivacaine hydrochloride is a potent sodium channel blocker and blocks impulse conduction via reversible inhibition of sodium ion influx in nerve fibrese. 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. Ropivacaine is widely used for neuropathic pain management in vivo.

Description

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].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:	Adult Sprague-Dawley rats (300–400g)^[2]
Dosage:	1 μM
Administration:	Infusion (added to the perfusate reservoir)
Result:	Attenuated pressure-dependent increases in filtration coefficient (K_f).

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 1 mg/mL (3.22 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1 mg/mL (3.22 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 1 mg/mL (3.22 mM); Clear solution

This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL Corn oil, and mix evenly.
