Vitamin H3

Vitamin H3 Uses, Dosage, Side Effects, Food Interaction and all others data.

A local anesthetic of the ester type that has a slow onset and a short duration of action. It is mainly used for infiltration anesthesia, peripheral nerve block, and spinal block. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1016). Vitamin H3 has also been investigated as an oral entry inhibitor in treatment-experienced HIV patients .

Vitamin H3 is an anesthetic agent indicated for production of local or regional anesthesia, particularly for oral surgery. Vitamin H3 (like cocaine) has the advantage of constricting blood vessels which reduces bleeding, unlike other local anesthetics like lidocaine. Vitamin H3 is an ester anesthetic. It is metabolized in the plasma by the enzyme pseudocholinesterase through hydrolysis into para-aminobenzoic acid (PABA), which is then excreted by the kidneys into the urine.

Uses

Vitamin H3 is a local anesthetic used for anesthesia, peripheral nerve block, and spinal nerve block.

Used as a local anesthetic primarily in oral surgery

Vitamin H3 is also used to associated treatment for these conditions: Otalgia

How Vitamin H3 works

Vitamin H3 acts mainly by inhibiting sodium influx through voltage gated sodium channels in the neuronal cell membrane of peripheral nerves. When the influx of sodium is interrupted, an action potential cannot arise and signal conduction is thus inhibited. The receptor site is thought to be located at the cytoplasmic (inner) portion of the sodium channel. Vitamin H3 has also been shown to bind or antagonize the function of N-methyl-D-aspartate (NMDA) receptors as well as nicotinic acetylcholine receptors and the serotonin receptor-ion channel complex.
