Procaine is an anesthetic agent indicated for production of local or regional anesthesia, particularly for oral surgery. Procaine (like cocaine) has the advantage of constricting blood vessels which reduces bleeding, unlike other local anesthetics like lidocaine. Procaine 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. Procaine 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. Procaine 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.
Ligustrazine (tetramethylpyrazine) is a bioactive ingredient extracted from the widely-used Chinese herb, Chuanxiong. It inhibits of platelet aggregation, enhances of vessel dilation, increases cerebral blood flow and possesses neuroprotective properties. The injection solution of ligustrazine has been used especially in China to treat ischemic stroke, coronary heart disease, diabetic nephropathy, and knee osteoarthritis. Ligustrazine was also evaluated in clinical as a remedy for pressure sores, as a salvage agent for patients with non-Hodgkin's lymphoma, as a treatment for bronchial asthma and vertebrobasilar insufficiency.
