4 Drug and Medication Information
4.1 Therapeutic Uses

Benzyl benzoate is used as an alternative agent for the topical treatment of scabies and also has been used for the topical treatment of pediculosis (lice infestation). ... Benzyl benzoate lotion, in an approximate concentration of 28% w/w, is applied topically. The drug should not be administered orally. Containers of the lotion should be shaken before using.

Scabicide, pediculicide.

O'Neil, M.J. (ed.). The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals. Cambridge, UK: Royal Society of Chemistry, 2013., p. 199


VET: Acaricide, pediculicide. Contraindicated in cats.

O'Neil, M.J. (ed.). The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals. Cambridge, UK: Royal Society of Chemistry, 2013., p. 199


4.2 Drug Warning

Studies in animals showed that oral ingestion of large doses of benzyl benzoate resulted in progressive incoordination, CNS excitation, seizures, and death.

American Society of Health-System Pharmacists; Drug Information 2018. Bethesda, MD. 2018


When used in appropriate dosage, topically applied benzyl benzoate appears to have a low order of toxicity. Slight local irritation (especially of the male genitalia), itching, and allergic skin sensitivity may occur, and contact with the face, eyes, mucous membranes, and urethral meatus should be avoided. Repeated application of benzyl benzoate frequently causes contact dermatitis.

American Society of Health-System Pharmacists; Drug Information 2018. Bethesda, MD. 2018


Benzyl benzoate is contraindicated in patients with a history of hypersensitivity to the drug.

American Society of Health-System Pharmacists; Drug Information 2018. Bethesda, MD. 2018


Benzyl benzoate should not be applied to acutely inflamed skin or raw, weeping surfaces. If primary irritation or hypersensitivity occurs, treatment should be discontinued and the drug removed with soap and water.

American Society of Health-System Pharmacists; Drug Information 2018. Bethesda, MD. 2018


VET: Cats are particularly susceptible to this action, and the use of benzyl benzoate in this species is therefore contraindicated. The most prominent feature is nervous excitability. The clinical signs resemble those of poisoning by benzoic acid.

Humphreys, D.J. Veterinary Toxicology. 3rd ed. London, England: Bailliere Tindell, 1988., p. 131


4.3 Drug Indication

Used to kill lice and the mites responsible for the skin condition scabies.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Benzyl benzoate is one of the older preparations used to treat scabies. Scabies is a skin infection caused by the mite sarcoptes scabiei. It is characterised by severe itching (particularly at night), red spots, and may lead to a secondary infection. Benzyl benzoate is lethal to this mite and so is useful in the treatment of scabies. It is also used to treat lice infestation of the head and body. Benzyl benzoate is not the treatment of choice for scabies due to its irritant properties.


5.2 MeSH Pharmacological Classification

Insecticides

Pesticides designed to control insects that are harmful to man. The insects may be directly harmful, as those acting as disease vectors, or indirectly harmful, as destroyers of crops, food products, or textile fabrics. (See all compounds classified as Insecticides.)


5.3 ATC Code

P - Antiparasitic products, insecticides and repellents

P03 - Ectoparasiticides, incl. scabicides, insecticides and repellents

P03A - Ectoparasiticides, incl. scabicides

P03AX - Other ectoparasiticides, incl. scabicides

P03AX01 - Benzyl benzoate


5.4 Absorption, Distribution and Excretion

Absorption

No data are available on percutaneous absorption of benzyl benzoate. Some older studies have suggested some percutaneous absorption, however the amount was not quantified.


The maternal and fetal toxicity of benzyl benzoate, commonly used as antiparasitic insecticide, was evaluated in pregnant rats after a daily oral dose of 25 and 100 mg/kg. Biochemical, histopathological, and morphological examinations were performed. Dams were observed for maternal body weights and food and water consumption and subjected to caesarean section on (GD) 20. Maternal and fetal liver, kidney, heart, brain, and placenta were examined histopathologically under light microscope. Maternal and fetal liver and placenta were stained immunohistochemically for vascular endothelial growth factor (VEGF). Morphometric analysis of fetal body lengths, placental measurements, and fetal skeletal stainings was performed. Statistically significant alterations in biochemical parameters and placental and skeletal measurements were determined in treatment groups. In addition to histopathological changes, considerable differences were observed in the immunolocalization of VEGF in treatment groups. These results demonstrated that benzyl benzoate and its metabolites can transport to the placenta and eventually enter the fetuses.

PMID:21922633 Kockaya EA, Kilic A et al; Environ Toxicol 29 (1): 40-53 (2014)


The percutaneous absorption of benzyl benzoate measured in vivo in human and monkey studies. With the application sites occluded, 54% of the applied dose penetrated human skin in 24 hr compared with 69% absorption in the monkey skin.

PMID:2379896 Bronaugh RL et al; Food Chem Toxicol 28 (5): 369-74 (1990)


5.5 Metabolism/Metabolites

Rapidly hydrolyzed to benzoic acid and benzyl alcohol, which is further oxidized to benzoic acid. The benzoic acid is conjugated with glycine to form hippuric acid.


Converted to hippuric acid in vivo.

5.6 Mechanism of Action

Benzyl benzoate exerts toxic effects on the nervous system of the parasite, resulting in its death. It is also toxic to mite ova, though its exact mechanism of action is unknown. In vitro, benzyl benzoate has been found to kill the Sarcoptes mite within 5 minutes.
