Tetracaine Basic Details

Описание:

Тетракаин, also known as amethocaine, is a local anesthetic used to numb the eyes, nose, or throat. Tetracaine may also be used before starting an intravenous to decrease pain from the procedure. Typically it is applied as a liquid to the area. Onset of effects when used in the eyes is within 30 seconds and last for less than 15 минут.

Tetracaine was patented in 1930 and came into medical use in 1941. It is on the World Health Organization’s List of Essential Medicines, the most effective and safe medicines needed in a health system. The wholesale cost in the developing world is about 1.34 к 1.63 USD per 10 ml bottle. In the United Kingdom the eye drops cost the NHS about 0.49 pounds per dose.

Tetracaine Application

(1) In biomedical research, tetracaine is used to alter the function of calcium release channels (ryanodine receptors) that control the release of calcium from intracellular stores. Tetracaine is an allosteric blocker of channel function. At low concentrations, tetracaine causes an initial inhibition of spontaneous calcium release events, while at high concentrations, tetracaine blocks release completely.

(2) Tetracaine is the T in Tac, a mixture of 5 к 12 per cent tetracaine, 5М(per myriad), a half per mille (0.5‰), или .05 per cent (1 part in 2000) , а также 4 или 10 per cent hydrochloride used in ear, nose & throat surgery and in the emergemcy department where numbing of the surface is needed rapidly, especially when children have been injured in the eye, ear, or other sensitive locations.

(3) Tetracaine is synthesized from 4-butylaminobenzoic acid. The ethyl ester is formed through an acid-catalyzed esterification reaction. Base-catalyzed transesterification is achieved by boiling the ethyl ester of 4-butylaminobenzoic acid with excess 2-dimethylaminoethanol in the presence of a small amount of sodium ethoxide.

Tetracaine Dosage:

Tetracaine is given as an injection through a needle placed into an area of your middle or lower back near your spine. You will receive this injection in a hospital setting.

Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving tetracaine injection.

Spinal numbing medicines can have long-lasting effects on certain body processes such as sexual function, bowel or bladder control, and movement or feeling in your legs or feet. Talk with your doctor about these effects.

Since this medicine is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

Since tetracaine is given as needed before a surgery or other medical procedure, you are not likely to be on a dosing schedule.
