Sterile Injectable Solution

Therapeutically classification: Local anesthetic and antiarrhythmic

Composition: Each ml contains:

 Lidocaine hydrochloride   20 mg

Target species: Horses, Cattle, Dogs and Cats


Treatment of arrhythmia (ventricular tachycardia and ventricular premature complexes) in all species

Local and regional anesthetic agent in all species especially farm animals

Epidural anesthesia

Treatment of post-operative ileus in horses


Mechanism of action:

Lidocaine is considered to be a class IB (membrane-stabilizing) antidysrhythmic agent. Local anesthetics inhibit the production and conduction of nerve impulses. However, the drug interferes with the permeability of the cell membrane to sodium ions, thereby reducing membrane permeability and blocking the conduction of nerve waves. In other words, these drugs inhibit nerve cell membrane depolarization, thereby preventing the propagation of action potential and subsequent nerve impulse conduction and affecting the anesthetic effect of the drug. Lidocaine directly reduces spontaneous depolarization and ventricular excitability during diastolic stage 4 with direct effect on the muscle tissue of the heart and especially the Purkinje network.

Dosage & Administration:


Caudal epidural anesthesia: 0.5-1 ml/50 kg B.W.

Cranial epidural anesthesia: 1 ml/5 kg B.W.


Maxillary nerve anesthesia: 10-20 ml

Epidural anesthesia: 5-10 ml

Treatment of arrhythmia: 0.25-0.5 mg/kg each 5-15 min by IV administration, for a total of 1.5 mg/kg, then as a CRI of 0.05 mg/kg/min

Treatment of Postoperative ileus: 1.3 mg/kg by IV administration over 15 min, followed as a CRI of 0.05 mg/kg/min

  • Analgesia: 2 mg/kg by IV administration, followed as a CRI of 0.05 mg/kg/min


Antiarrhythmic: 1-2 mg/kg by IV administration during 30 s and increase to 4 mg/kg B.W. if there has been no response.

Epidural: 4.4 mg/ kg B.W. to anesthetize up to the first lumbar vertebra (L1).


  • Antiarrhythmic: Start with 0.1-0.4 mg/kg initially and then increase to 0.25-0.75 mg/kg by slow IV administration if there has been no response.

Antiarrhythmic: Loading dose of 0.5-1 mg/kg IV, followed by 10-20 µg/kg/min (0.6-1.2 mg/kg/hr.) IV CRI.

  • Epidural: 4.4 mg/kg B.W.


Withdrawal time:

Meat: 3 days after the last treatment

Milk: 2 days after the last treatment


Do not use in hypersensitivity to lidocaine.

Do not use in infectious tissues and foci.

In the presence of septicemia, severe bleeding, hypotension, shock, complete cardiac block, should not be injected into the subarachnoid space.

High doses cause drowsiness, vomiting, seizure, nystagmus, sudden brain-heart attack, Excitement, hypotension, increase conduction of waves and atrioventricular contractions.


Cats are reportedly very sensitive to the CNS effects of lidocaine, monitor carefully and treat seizures with diazepam.

Keep out of reach and sight of children.

Use only under the prescription of a veterinarian.

In use stability:

28 days after first needle insertion.


Do not store above 25°C, keep away from light and freezing.
