Absorption, Distribution and Excretion
In rats, guaiacol is rapidly absorbed, being present in the blood 5 minutes after oral administration, and reaching its peak plasma concentration in about 10 minutes. Its elimination from the blood is usually as rapid.
Excreted by rabbits in combined form with sulfate (15%) and glucuronic acid (72%).
CREOSOTE IS RAPIDLY ABSORBED FROM THE GASTROENTERIC TRACT AND THROUGH THE SKIN. IT APPEARS TO BE EXCRETED IN THE URINE MAINLY IN CONJUGATION WITH SULFURIC, HEXURONIC, & OTHER ACIDS. OXIDATION ALSO OCCURS WITH THE FORMATION OF CMPD THAT IMPART A SMOKY APPEARANCE TO THE URINE. TRACES ARE EXCRETED BY WAY OF THE LUNGS.

其他信息
O-methoxyphenol appears as colorless to amber crystals or liquid. Density (of solid) 1.129 g / cm3. Solidifies at 28 °C (82.4 °F), but may remain liquid for a long time even at a much lower temperature. Slightly water soluble. Soluble in aqueous sodium hydroxide. Used medicinally as an expectorant. Used, because of its anti-oxidant properties, as an anti-skinning agent for paints.
Guaiacol is a monomethoxybenzene that consists of phenol with a methoxy substituent at the ortho position. It has a role as an expectorant, a disinfectant, a plant metabolite and an EC 1.1.1.25 (shikimate dehydrogenase) inhibitor. It is functionally related to a catechol.
Guaiacol is an agent thought to have disinfectant properties and used as an expectorant. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma.
Guaiacol has been reported in Angelica gigas, Rhodotorula mucilaginosa, and other organisms with data available.
Guaiacol is a phenolic compound with a methoxy group and is the monomethyl ether of catechol. Guaiacol is readily oxidized by the heme iron of peroxidases including the peroxidase of cyclooxygenase (COX) enzymes. It therefore serves as a reducing co-substrate for COX reactions. Guaiacol is a phenolic natural product first isolated from Guaiac resin and the oxidation of lignin. It is a yellowish aromatic oil that is now commonly derived from guaiacum or wood creosote. It is used medicinally as an expectorant, antiseptic, and local anesthetic. Guaiacol is used in traditional dental pulp sedation, and has the property of inducing cell proliferation; guaiacol is a potent scavenger of reactive oxygen radicals and its radical scavenging activity may be associated with its effect on cell proliferation. Guaiacol is also used in the preparation of synthetic vanillin. Guaiacol is also present in wood smoke, as a product of pyrolysis of lignin. Guaiacol has been found in the urine of patients with neuroblastoma and pheochromocytoma. (A3556, A3559).

For the symptomatic relief of coughs associated with colds, bronchial catarrh, influenza and upper respiratory tract infections such as laryngitis and pharyngitis. Codeine is a well-known centrally acting cough suppressant. Guaiacol acts as an expectorant, loosening bronchial secretions in the respiratory tract. /Guaiacol, codeine combination/
Drug Warnings
THE REPEATED ABSORPTION OF THERAPEUTIC DOSES FROM GASTROENTERIC TRACT MAY INDUCE SIGNS OF CHRONIC INTOXICATION, CHARACTERIZED BY DISTURBANCES OF VISION & DIGESTION (INCR PERISTALSIS & EXCRETION OF BODY FECES). IN ISOLATED CASES OF "SELF-MEDICATION", HYPERTENSION & ALSO GENERAL CARDIOVASCULAR COLLAPSE HAVE BEEN DESCRIBED.
WHEREVER CREOSOTE IS INDICATED FOR INTERNAL MEDICATION CREOSOTE FROM WOOD TAR SHOULD BE DISPENSED & UNDER NO CIRCUMSTANCES SHOULD CREOSOTE FROM COAL TAR BE GIVEN, UNLESS EXPLICITLY SO DIRECTED.
