Product Snapshot
- Mepivacaine is an injectable small‑molecule local anesthetic supplied primarily as liquid and solution formulations for parenteral administration
- It is used for local and regional anesthesia applications including infiltration, peripheral nerve block, and central neuraxial techniques
- It is approved for human and veterinary use in the US and Canada
Clinical Overview
Mepivacaine produces anesthesia through reversible blockade of voltage‑gated sodium channels in neuronal membranes. This action increases the threshold for electrical excitation, slows impulse propagation, and reduces the rate of rise of the action potential. Clinical block progression typically follows a predictable sequence with loss of pain perception first, followed by temperature, touch, proprioception, and skeletal muscle tone.
Pharmacodynamically, mepivacaine has a reasonably rapid onset and a medium duration of action. Systemic absorption can lead to central nervous system and cardiovascular effects, although therapeutic concentrations usually result in minimal changes in cardiac conduction and contractility. Proprietary formulations have been marketed under names such as Carbocaine and Polocaine.
Absorption is influenced by vascularity of the injection site and dose. Distribution occurs into highly perfused tissues with protein binding typical of amide anesthetics. Metabolism primarily involves hepatic biotransformation, and renal elimination is the major route for metabolites and unchanged drug. Reduced hepatic function may slow clearance, increasing systemic exposure.
Safety considerations include the risk of CNS excitation or depression and cardiovascular depression at elevated plasma levels. As with other amide anesthetics, excessive dosing or rapid intravascular absorption increases the likelihood of systemic toxicity. Mepivacaine is also associated with methemoglobinemia, although this is uncommon.
For API procurement, sourcing should prioritize verified identity, impurity control consistent with pharmacopeial or regulatory specifications, and reliable assessment of residual solvents and particle characteristics to support formulation and manufacturing suitability.

Pharmacology
| Summary | Mepivacaine is an amide local anesthetic that blocks voltage‑gated sodium channels, increasing the excitation threshold and slowing impulse propagation to prevent nerve signal conduction. Its anesthetic effects follow the typical functional loss pattern for local anesthetics and provide a rapid-onset, medium-duration nerve blockade. Systemic exposure can influence cardiovascular and central nervous system function, though therapeutic concentrations generally produce minimal conduction or contractility changes. |
|---|---|
| Mechanism of action | 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: pain, temperature, touch, proprioception, and skeletal muscle tone. |
| Pharmacodynamics | Mepivicaine is an amide local anesthetic. Mepivicaine as a reasonably rapid onset and medium duration and is known by the proprietary names as Carbocaine and Polocaine. Mepivicaine is used in local infiltration and regional anesthesia. Systemic absorption of local anesthetics produces effects on the cardiovascular and central nervous systems. At blood concentrations achieved with normal therapeutic doses, changes in cardiac conduction, excitability, refractoriness, contractility, and peripheral vascular resistance are minimal. |

| Absorption | Absorbed locally. The rate of systemic absorption of local anesthetics is dependent upon the total dose and concentration of drug administered, the route of administration, the vascularity of the administration site, and the presence or absence of epinephrine in the anesthetic solution. |
|---|---|
| Half-life | The half-life of mepivacaine in adults is 1.9 to 3.2 hours and in neonates 8.7 to 9 hours. |
| Protein binding | Mepivacaine is approximately 75% bound to plasma proteins. Generally, the lower the plasma concentration of drug, the higher the percentage of drug bound to plasma. |
| Metabolism | Rapidly metabolized, with only a small percentage of the anesthetic (5 percent to 10 percent) being excreted unchanged in the urine. The liver is the principal site of metabolism, with over 50% of the administered dose being excreted into the bile as metabolites. |
| Route of elimination | It is rapidly metabolized, with only a small percentage of the anesthetic (5 percent to 10 percent) being excreted unchanged in the urine.The liver is the principal site of metabolism, with over 50% of the administered dose being excreted into the bile as metabolites. |
Formulation & handling
- Parenteral-only local anesthetic requiring aqueous injectable formulations; moderate lipophilicity and low water solubility may necessitate pH adjustment or co-solvents for solubilization.
- Chemically stable small molecule amide anesthetic; solutions are typically buffered to maintain potency and minimize precipitation during storage.
- Widely used for infiltration, epidural, and dental administration, so formulation must ensure low particulate load and compatibility with common infusion and regional anesthesia delivery materials.
Regulatory status

- Seizure threshold observed in primates at ~18
- 8 mg/kg (arterial plasma ~24
- 4 µg/mL) indicates a narrow margin between effective concentrations and CNS toxicity
Mepivacaine is a type of Local anesthetics
Local anesthetics are a category of pharmaceutical Active Pharmaceutical Ingredients (APIs) commonly used to numb a specific area of the body during medical procedures or surgeries. They work by blocking the transmission of nerve signals, preventing the sensation of pain in the targeted region. Local anesthetics are vital for various medical applications, including dental procedures, minor surgeries, and childbirth.
The main mechanism of action for local anesthetics involves the reversible inhibition of sodium channels, which are responsible for the conduction of nerve impulses. By binding to these channels, local anesthetics prevent the influx of sodium ions, which blocks the generation and propagation of nerve signals. This results in temporary loss of sensation in the area where the medication is administered.
Local anesthetics can be categorized into two main types: esters and amides. Esters, such as procaine and benzocaine, are metabolized by plasma esterases, while amides, including lidocaine and bupivacaine, undergo hepatic metabolism. The choice of local anesthetic depends on factors such as the duration of action required, the specific procedure being performed, and the patient's medical history.
It is important to note that local anesthetics should be administered with caution, as they can have potential side effects, including allergic reactions, systemic toxicity, and nerve damage if used improperly. Therefore, proper dosage and administration techniques must be followed to ensure patient safety.
In summary, local anesthetics are essential pharmaceutical APIs used to temporarily block nerve signals, providing localized pain relief during medical procedures. Understanding the different types and their mechanisms of action allows healthcare professionals to select the most appropriate local anesthetic for each patient and procedure, ensuring optimal outcomes and patient comfort.
