🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAbsorption of this medicine depends on the route of administration and the vascularity of the injection site. Systemic absorption occurs when the medicine enters the bloodstream, which can lead to toxicity if excessive.
DistributionThis medicine is distributed throughout the body, with higher concentrations in highly perfused organs such as the liver, lungs, heart, and brain. It crosses the placenta and can affect the foetus.
Protein BindingApproximately 95% bound to plasma proteins, primarily alpha-1-acid glycoprotein.
MetabolismThis medicine is metabolised in the liver by conjugation with glucuronic acid and by amide hydrolysis.
Half-LifeThe elimination half-life is approximately 2.7 hours in adults, but may be prolonged in neonates and patients with hepatic impairment.
ExcretionMetabolites are excreted primarily in the urine, with only a small amount excreted unchanged.
BioavailabilityNot applicable for intrathecal, epidural, or peripheral nerve block administration as it is not intended for systemic absorption.
Onset of ActionOnset of action varies with the route: for spinal anaesthesia, onset is within 5-10 minutes; for epidural, 10-20 minutes; for peripheral nerve blocks, 10-30 minutes.
Peak Plasma TimePeak plasma concentration depends on the route and dose, typically occurring within 30-60 minutes after epidural administration.
Duration of ActionDuration of action ranges from 2 to 8 hours depending on the route, dose, and presence of vasoconstrictors. For spinal anaesthesia, it lasts 2-3 hours; for epidural, 3-5 hours; for peripheral nerve blocks, 4-8 hours.

How It Works

This medicine works by blocking sodium ion channels in the nerve cell membrane, thereby preventing the generation and conduction of nerve impulses. It binds to the intracellular portion of the voltage-gated sodium channels, stabilising the neuronal membrane and inhibiting depolarisation. This results in reversible loss of sensation in the area supplied by the affected nerves.

Mechanism Steps

1
Diffusion to nerve membrane: After administration, the medicine diffuses through the tissues to reach the nerve membrane.
2
Binding to sodium channels: It binds to the intracellular side of voltage-gated sodium channels in the nerve membrane.
3
Blockade of sodium influx: This binding blocks the influx of sodium ions, preventing depolarisation of the nerve.
4
Inhibition of impulse conduction: As a result, the generation and propagation of action potentials are inhibited, leading to loss of sensation.

Dosage Information

Adult DosageThe dose of this medicine varies depending on the procedure, route of administration, and patient factors. For spinal anaesthesia, a typical dose is 2-3 mL of 0.5% solution (10-15 mg). For epidural anaesthesia, doses range from 10-20 mL of 0.25-0.5% solution. For peripheral nerve blocks, doses vary. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may require lower doses due to reduced physiological reserve and increased sensitivity. Dose must be individualized by a qualified clinician.
Renal ImpairmentNo specific dose adjustment is established, but use with caution in severe renal impairment.
Hepatic ImpairmentUse with caution in severe hepatic impairment. Dose reduction may be necessary.
Maximum Daily DoseThe maximum dose should not exceed 2 mg/kg for adults. For a 70 kg adult, the maximum dose is 140 mg. However, the dose must be individualized by a qualified clinician.
