5. Pharmacological Properties
5.1 Pharmacodynamic Properties
Lignocaine Hydrochloride is well documented in Martindale 28th Edition page 900 - 904 and Goodman & Gilman, chapter 15 and pages 767 - 770.
Lignocaine Hydrochloride was first introduced in 1948 and is one of the most widely used local anaesthetics. However, it produces more prompt, more intense, longer lasting and more extensive anaesthesia than does an equal concentration of procaine (Peak anaesthesia within 2-5 minutes). Local anaesthetics are drugs that block nerve conduction when applied locally to nerve tissue in appropriate concentrations. They have good powers of penetration and their action is reversible. Their use is followed by complete recovery in nerve function with no evidence of structural damage to nerve fibres or cells.
Aminacrine Hydrochloride is a slow acting disinfectant. It exerts germicidal action against bacteria and fungi. It is also used as a surgical and endodontic irrigant and to treat local infections of the ear, mouth and throat. Its exact mode of action is not known but it involves disruption of certain metabolic pathways.
5.2 Pharmacokinetic Properties
Lignocaine is readily absorbed through mucous membranes. They exert their effects in the form of the non-ionised base. Lignocaine undergoes first-pass metabolism in the liver and bioavailablity is low after administration by mouth. It is rapidly de-ethylated to the active metabolite monoethylglycinexylidide and then hydrolysed by amidases to various compounds, including glycineexylidide which has reduced activity but a longer elimination half-life. Less than 10% of a dose is excreted unchanged via the kidneys. The metabolic products are excreted in the urine.
Aminacrine Hydrochloride if administered systematically is rapidly eliminated through the kidney (0.2 g being eliminated from the blood in 30 minutes. Medijel Pastilles dose 0.15mg Aminacrine Hydrochloride).
5.3 Preclinical Safety Data
There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the SPC.
