Ropivacaine Hydrochloride is the hydrochloride salt of ropivacaine, a local anesthetic of the amide type with analgesic activity. Ropivacaine binds to voltage-gated sodium ion channels in the neuronal membrane, thereby preventing the permeability of sodium ions and resulting in a stabilization of the neuronal membrane and inhibition of depolarization; nerve impulse generation and propagation are blocked, resulting in a reversible loss of sensation.

Ropivacaine Injection Description

Ropivacaine Hydrochloride Injection, USP contains ropivacaine HCl which is a member of the amino amide class of local anesthetics. Ropivacaine Hydrochloride Injection, USP is a sterile, isotonic solution that contains the enantiomerically pure drug substance, sodium chloride for isotonicity and water for injection. Sodium hydroxide and/or hydrochloric acid may be used for pH adjustment. It is administered parenterally.

Ropivacaine HCl is chemically described as S-(-)-1-propyl-2',6'-pipecoloxylidide hydrochloride monohydrate. The drug substance is a white crystalline powder, with the following structural formula:

At 25°C ropivacaine HCl has a solubility of 53.8 mg/mL in water, a distribution ratio between n-octanol and phosphate buffer at pH 7.4 of 14:1 and a pKa of 8.07 in 0.1 M KCl solution. The pKa of ropivacaine is approximately the same as bupivacaine (8.1) and is similar to that of mepivacaine (7.7). However, ropivacaine has an intermediate degree of lipid solubility compared to bupivacaine and mepivacaine.

Ropivacaine Hydrochloride Injection, USP is preservative-free and is available in single dose containers in 2 (0.2%), 5 (0.5%), 7.5 (0.75%) and 10 mg/mL (1%) concentrations. The specific gravity of Ropivacaine Hydrochloride Injection, USP solutions range from 1.002 to 1.005 at 25°C.

Ropivacaine Injection - Clinical Pharmacology

Mechanism of Action

Ropivacaine is a member of the amino amide class of local anesthetics and is supplied as the pure S-(-)-enantiomer. Local anesthetics block the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse, and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination and conduction velocity of affected nerve fibers. Clinically, the order of loss of nerve function is as follows: (1) pain, (2) temperature, (3) touch, (4) proprioception, and (5) skeletal muscle tone.
