lurocaine med vet

lurocaine med vet is a sterile injectable local anesthetic used in veterinary medicine to provide local or regional anesthesia during procedures or to relieve pain from injury, surgery, or diagnostics. It contains lidocaine hydrochloride, which blocks nerve impulses by inhibiting sodium channels.

It is analogous to Xylocaine (human and veterinary use), but labeled for veterinary administration.

Indications (Uses)

Used in a variety of species, including horses, cattle, dogs, cats, pigs, and small ruminants for:

Local or Regional Anesthesia:

Infiltration anesthesia (minor surgical sites)

Nerve blocks (e.g., dental, limb)

Epidural anesthesia (especially in cattle and horses)

Line blocks (e.g., flank anesthesia in cows)

Other Uses:

Aid in urethral catheterization

Diagnostic nerve blocks in lameness exams (horses)

Occasionally in emergency arrhythmias (IV use in small animals – off-label, and usually requires a different lidocaine product)

Mechanism of Action

Lidocaine (active in Lurocaine) works by:

Blocking voltage-gated sodium channels in neuronal membranes

Preventing nerve signal transmission

Resulting in temporary loss of sensation or pain relief in the area

Effect is rapid in onset and moderate in duration.

lurocaine med vet Dosage and Administration

Always administered by a veterinarian or trained professional.

Typical Dosages (by route and species):

Maximum safe dose:

Lidocaine without epinephrine:

Dogs: 4–6 mg/kg

Cats: 1–2 mg/kg (more sensitive)

Horses: up to 4 mg/kg depending on route and condition

Cattle: depends on site; epidural dose often 0.2–0.5 mg/kg

Toxic if overdosed, especially in cats and small animals

Onset and Duration

Onset: 2–5 minutes

Duration:

30–60 minutes (infiltration)

Up to 90 minutes (epidural)

Shorter if used IV

May be combined with epinephrine to prolong effect and reduce bleeding (off-label in veterinary use). lurocaine med vet

Veterinary Insight

Gold-standard choice for field blocks and epidurals in cattle

Preferred agent in lameness diagnostics in horses (low toxicity, fast acting)

Must be used carefully in small animals, especially cats lurocaine med vet

Always ensure dose calculation is accurate, especially for nerve blocks and epidurals
