Mepivacainhydrochlorid Deltamedica (Mepivacaine Hydrochloride)

Mepivacaine Hydrochloride is employed in local anesthesia for procedures involving the oral cavity, surgery, and epidural analgesia.

• Dental procedures: provides effective local anesthesia for tooth extractions, restorations and periodontal surgery.
• Surgical anesthesia: enables regional or infiltration anesthesia for minor to moderate surgical interventions.
• Epidural analgesia: delivers analgesic effect for labor, postoperative pain and chronic pain management.

• Mepivacaine Hydrochloride acts by reversibly binding to the intracellular portion of voltage‑gated sodium channels on neuronal membranes, stabilizing the inactive state of the channel. This inhibition prevents the rapid influx of sodium ions required for depolarization, thereby blocking the generation and propagation of nerve impulses. The result is a rapid onset of sensory and motor block without significant vasodilation, allowing effective local anesthesia.

Mepivacaine Hydrochloride may be associated with a range of adverse reactions, varying from mild to severe.

Common Side Effects

• Transient numbness at the injection site.
• Mild tingling or paresthesia.
• Dizziness or light‑headedness.
• Headache.
• Nausea.
• Temporary hypotension.

Serious or Rare Side Effects

• Cardiac arrhythmias or conduction disturbances.
• Seizures.
• Methemoglobinemia.
• Severe allergic reactions (anaphylaxis).
• Prolonged or incomplete nerve block.
• Respiratory depression.

When using Mepivacaine Hydrochloride, several precautions should be observed to ensure patient safety.

• Patient assessment: evaluate cardiac history and existing conduction abnormalities before administration.
• Dose limitation: avoid exceeding recommended maximum dose for the specific route.
• Epinephrine use: limit or avoid high concentrations of epinephrine in combination.
• Monitoring: observe vital signs and neurological status during and after the procedure.
• Contraindications: do not use in patients with known hypersensitivity to amide‑type local anesthetics.
• Store below 25°C: keep in the original container, protect from moisture and light.

Mepivacaine Hydrochloride can interact with other medicines, affecting its efficacy or safety.

Major Interactions (Avoid)

• Class I antiarrhythmic agents (e.g., quinidine, procainamide) – may enhance cardiotoxicity.
• Monoamine oxidase inhibitors – increase risk of hypertensive crisis when combined with epinephrine.
• Beta‑blockers – can potentiate bradycardia and hypotension.
• Other local anesthetics – risk of cumulative toxicity.
• High‑dose epinephrine – may increase systemic toxicity.

Moderate Interactions (Monitor Closely)

• CYP450 inhibitors (e.g., cimetidine) – may reduce metabolism of mepivacaine.
• Systemic antibiotics such as erythromycin – may increase plasma levels.
• Diuretics – may alter plasma protein binding.
• Sedatives or CNS depressants – enhance central nervous system effects.
• Antihistamines – may mask early signs of allergic reaction.
