4.2 Drug Warning

Dil phenol solutions (1 to 2%) are used medicinally as antipruritic preparations for the skin. Their repeated use over large skin areas or on particularly moist areas (axillary region, groin, feet) should be avoided.

Gosselin, R.E., R.P. Smith, H.C. Hodge. Clinical Toxicology of Commercial Products. 5th ed. Baltimore: Williams and Wilkins, 1984., p. III-344


Soln of phenol (6%) in glycerine are sometimes employed in medical practice to produce nerve blocks. The spread of phenol beyond the intended site (stellate ganglion) resulted in infarction on the cervical cord with extensive paralysis in one patient and neurolosis of the cervical posterior roots with respiratory arrest in another.

4.3 Minimum/Potential Fatal Human Dose

Ingestion of as little as 4.8 g of pure phenol caused death in 10 min.

NIOSH; Criteria Document: Phenol p.65 (1976) DHEW Pub NIOSH 76-196


4.4 Drug Indication

Phenol is primarily indicated for minor sore throat pain, sore mouth, minor mouth irritation, and pain associated with canker sores. Additionally, phenol is indicated in the treatment of focal spasticity.


5 Pharmacology and Biochemistry
5.1 MeSH Pharmacological Classification

Sclerosing Solutions

Chemical agents injected into blood vessels and lymphatic sinuses to shrink or cause localized THROMBOSIS; FIBROSIS, and obliteration of the vessels. This treatment is applied in a number of conditions such as VARICOSE VEINS; HEMORRHOIDS; GASTRIC VARICES; ESOPHAGEAL VARICES; PEPTIC ULCER HEMORRHAGE. (See all compounds classified as Sclerosing Solutions.)


Disinfectants

Substances used on inanimate objects that destroy harmful microorganisms or inhibit their activity. Disinfectants are classed as complete, destroying SPORES as well as vegetative forms of microorganisms, or incomplete, destroying only vegetative forms of the organisms. They are distinguished from ANTISEPTICS, which are local anti-infective agents used on humans and other animals. (From Hawley's Condensed Chemical Dictionary, 11th ed) (See all compounds classified as Disinfectants.)


Anti-Infective Agents, Local

Substances used on humans and other animals that destroy harmful microorganisms or inhibit their activity. They are distinguished from DISINFECTANTS, which are used on inanimate objects. (See all compounds classified as Anti-Infective Agents, Local.)

5.3 Absorption, Distribution and Excretion

Absorption

Phenol is rapidly absorbed through the skin and into the lungs.


Route of Elimination

The kidney is the primary route of elimination of phenol.


Volume of Distribution

At I5 min after exposure, the liver contained the highest level of phenol, consisting mainly of free phenol. After 82 minutes post administration, phenol is uniformly distributed in the liver, blood, kidneys, lungs, along with the heart, testes, thymus and the spleen. With the passage of time, the proportion of free to conjugated phenol changed. By 360 minutes most phenol appears in conjugated forms.


Clearance

In rabbits, 72% is excreted in the urine, 1% in the feces, 4% in the carcass following sacrifice, and trace amounts were exhaled.


Phenol is absorbed by all routes of administration and can reach circulation even when applied to intact skin.

Gilman, A. G., L. S. Goodman, and A. Gilman. (eds.). Goodman and Gilman's The Pharmacological Basis of Therapeutics. 6th ed. New York: Macmillan Publishing Co., Inc. 1980., p. 967


Absorption of 2 g of phenol could result from 8 hr inhalation at about 50 ppm.

American Conference of Governmental Industrial Hygienists, Inc. Documentation of the Threshold Limit Values, 4th ed., 1980. Cincinnati, Ohio: American Conference of Governmmental Industrial Hygienists, Inc., 1980., p. 328


The extent of absorption of phenol through rabbit skin is more strongly influenced by the area of the skin exposed than by the concentration of the applied solution in water.

WHO; Environ Health Criteria 161: Phenol (1994). Available from, as of April 1, 2003: https://www.inchem.org/documents/ehc/ehc/ehc161.htm#PartNumber:6


Renal excretion is principal route of elimination. ... In man 90% of non-toxic oral dose (0.01 mg/kg) of (14)C-labeled phenol was excreted in 24 hr, principally as sulfate (77% of the excreted label) and as glucuronide (16%), with small amt of sulfate and glucuronide conjugates of ... hydroquinone. With larger doses, free (unmetabolized) phenol can presumably be found in urine.

Gosselin, R.E., R.P. Smith, H.C. Hodge. Clinical Toxicology of Commercial Products. 5th ed. Baltimore: Williams and Wilkins, 1984., p. III-346

5.4 Metabolism/Metabolites

Phenyl sulfate, phenyl glucuronide, quinol sulfate, and quinol glucuronide were detected in human beings as phenol metabolites.


Phenols are subjected to oxidative metabolism leading to ortho- and para-hydroxylated products. These metabolites are then transformed into equimolar amounts of two conjugates, sulfates and glucuronides.

Britt DL, Hushon JM; Biol Effects, Crit and Stand Haz Pollut Assoc Energy Technol p.29 (1976)


Metabolism in rabbits given a lethal dose of phenol (0.5 g/kg) resulted in: 47% oxidation to carbon dioxide and water plus traces of 1,4-dihydroxybenzene and ortho-dihydroxybenzene, 3% excreted in urine, 50% remaining in the carcass. Amounts were exhaled in air and excreted in in the feces. Metabolism in rabbits given a sublethal dose of phenol (0.3 g/kg) resulted in: 23% oxidation to carbon dioxide and water plus traces of 1,4-dihydroxybenzene and ortho-dihydroxybenzene, 72% excreted in the urine, 4% remaining in the carcass, 1% excreted in the feces, and trace amounts exhaled in air. Urinary route resulted in either excretion as free phenol or as conjugate. (Conjugation with sulfuric acid, glucuronic acid or other acids). /From figure/

USEPA; Ambient Water Quality Criteria Doc: Phenol p.C-16-19 (1980) EPA 440/5-80-066


The cat was shown to be sensitive to phenol. In addition to sulfate conjugates, free 1,4-dihydroxybenzene was found as a major metabolite which may account for the toxicity observed in the cat.

USEPA; Ambient Water Quality Criteria Doc: Phenol p.C-19 (1980) EPA 440/5-80-066


Some species differences have been noted in the metabolism of phenol. Man, rat, mouse, jerboa, gerbil, hamster, lemming, and guinea pig excreted four metabolites: sulfate and glucuronic acid conjugates of phenol and of 1,4-dihydroxybenzene. The squirrel and capuchin monkeys excreted phenol glucuronide, 1,4-dihydroxybenzene glucuronide, and phenol sulfate. The ferret, dog, hedgehog, and rabbit excreted phenol sulfate, 1,4-dihydroxybenzene sulfate, and phenyl glucuronide. The Rhesus monkey, fruit bat, and chicken excreted phenyl sulfate and phenyl glucuronide but not 1,4-dihydroxybenzene conjugates. The cat excreted only phenyl sulfate and 1,4-dihydroxybenzene sulfate, and the pig excreted phenyl glucuronide as its major phenol metabolite. Relatively low doses were utilized in this study.

5.5 Biological Half-Life

Urine: 3.5 hours; [TDR, p. 1020]

TDR - Ryan RP, Terry CE, Leffingwell SS (eds). Toxicology Desk Reference: The Toxic Exposure and Medical Monitoring Index, 5th Ed. Washington DC: Taylor & Francis, 1999., p. 1020


Elimination half-life was 13.86 hours, considerably longer than previously reported /in a 47 yr old male with accidental dermal exposure to his left foot (3% of body surface area)/.

PMID:9865239 Bentur Y et al; J Toxicol Clin Toxicol 36 (7): 707-11 (1998)


The excretion of phenol was studied in human volunteers exposed to phenol by inhalation or skin absorption. The human body behaved almost like a single compartment with respect to phenol absorption and clearance with an excretion rate constant of K= 0.2/hr This corresponds to a half-life of approximately 3.5 hours.

USEPA; Ambient Water Quality Criteria Doc: Phenol p.C-20 (1980) EPA 440/5-80-066


5.6 Mechanism of Action

Phenol is a potent proteolytic agent. Concentrations in the 5% to 7% range dissolve tissue on contact via proteolysis. In high concentrations when injected next to a nerve, phenol produces a chemical neurolysis which is nonselective across nerve fiber size and most prominent on its outer aspect. Local anesthetic effects occur within 5-10 minutes.


The effects of monoamine depletors and monoamine denervators on phenol induced tremor were studied in mice. The tremor induced by phenol was enhanced by pretreatment with reserpine or tetrabenazine, but not with syrosingopine. However, alpha-methyl-p-tyrosine, p-chlorophenylalanine or 6-hydroxydopamine did not affect the tremor. These results suggest that the depletion of central monoamines as a whole contribute to the enhancement of the tremor induced by phenol.
