5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Stomatological Preparation, ATC code: A01AD

Cetylpyridium Chloride is a cationic disinfectant which is used for minor wounds, treating superficial infections of the mouth and preserving the product.

Lidocaine Hydrochloride is a local anaesthetic. It works by blocking nerve conduction when applied topically to nerve tissue. It acts on any part of the nervous system and on every type of nerve fibre. For example, when it is applied to the motor cortex, impulse transmission from that area stops, and when it is injected into the skin it prevents the initiation and the transmission of the sensory impulses. A local anaesthetic in contact with a nerve trunk can cause both sensory and motor paralysis in the area innervated. Many kinds of compounds interfere with conduction, but they often permanently damage the nerve cells. The great practical advantage of the local anaesthetics is that their use is reversible, their use is followed by complete recovery in nerve function with no evidence of structural damage to nerve fibres or cells.

5.2 Pharmacokinetic properties

Lidocaine produces more prompt, more intense, longer-lasting and more intense anaesthesia than does an equal concentration of procaine. Unlike procaine it is an aminoethylamide. It is an agent of choice, therefore, in individuals sensitive to ester-type local anaesthetics. Lidocaine is relatively quickly absorbed. Lidocaine is metabolised in the liver by mixed-function oxidases by dealkylation to monoethyl glycine and xylidide. The latter compound retains significant local anaesthetic and toxic activity. In man about 75% of xylidide is excreted in the urine as the further metabolite 4-hydroxy-2,6-dimethylaniline. The typical dose of Dentinox gel is about 150mg containing about 0.5mg of lidocaine hydrochloride (which approximates to about 0.1 mg/kg of bodyweight). Martindale recommends that the total dose of lidocaine hydrochloride should not exceed 200mg (3mg per kg of bodyweight). Thus, the dosage of Dentinox Gel is well within this level.
