procaine profile

Procaine is a local anesthetic that blocks nerve conduction by inhibiting the influx of sodium ions into nerve cells. It is synthesized by reacting p-aminobenzoic acid with diethylaminoethanol. Procaine is typically administered by injection and is used to provide pain relief during medical procedures, such as dental work, surgery, and childbirth. It is also used to treat certain types of pain, such as chronic pain and neuralgia. Procaine is an important drug because it is effective, safe, and relatively inexpensive. It is studied to develop new and improved local anesthetics, and to investigate its potential therapeutic uses, such as in the treatment of cancer and inflammatory diseases.'

Procaine: 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). [Medical Subject Headings (MeSH), National Library of Medicine, extracted Dec-2023]

procaine : A benzoate ester, formally the result of esterification of 4-aminobenzoic acid with 2-diethylaminoethanol but formed experimentally by reaction of ethyl 4-aminobenzoate with 2-diethylaminoethanol.

Role	Description
local anaesthetic	Any member of a group of drugs that reversibly inhibit the propagation of signals along nerves.

central nervous system depressant	A loosely defined group of drugs that tend to reduce the activity of the central nervous system.
peripheral nervous system drug	A drug that acts principally at one or more sites within the peripheral neuroeffector systems, the autonomic system, and motor nerve-skeletal system.
drug allergen	Any drug which causes the onset of an allergic reaction.

vitamin b 6 Vitamin B 6: VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990).

Localized tetanus presents itself as a mild condition with manifestations restricted to muscles near the wound. It may progress to the generalized form.	0	9.01	15	0

Pheochromocytoma A usually benign, well-encapsulated, lobular, vascular tumor of chromaffin tissue of the ADRENAL MEDULLA or sympathetic paraganglia. The cardinal symptom, reflecting the increased secretion of EPINEPHRINE and NOREPINEPHRINE, is HYPERTENSION, which may be persistent or intermittent. During severe attacks, there may be HEADACHE; SWEATING, palpitation, apprehension, TREMOR; PALLOR or FLUSHING of the face, NAUSEA and VOMITING, pain in the CHEST and ABDOMEN, and paresthesias of the extremities. The incidence of malignancy is as low as 5% but the pathologic distinction between benign and malignant pheochromocytomas is not clear.
