  • TITLE: Lindane and Other Treatments for Lice and Scabies: a Review of Clinical Effectiveness and Safety
    TITLE: Lindane and Other Treatments for Lice and Scabies: A Review of Clinical Effectiveness and Safety DATE: 11 June 2010 CONTEXT AND POLICY ISSUES: Head lice infestation (Pediculosis capitis) affects millions of children and adults worldwide each year.1 Direct head-to-head contact is the most common mode of transmission.2 The highest prevalence of infestation occurs in school aged children aged three to eleven years, with girls being more commonly affected than boys.1,2 Although head lice are not generally associated with serious morbidity, they are responsible for significant social embarrassment and lost productivity in schools or offices.1 Scabies, an infestation of the skin by the mite Sarcoptes scabiei, represents a common public health concern particularly in overcrowded communities with a high prevalence of poverty.3 Scabies is transmitted by close-person contact and occasionally by clothing or linens.3 Complications include secondary bacterial infections and post-streptococcal glomerulonephritis.3 Topical products available in Canada for the treatment of head lice and scabies are presented in Appendix 1 and Appendix 2. Insecticidal agents such as permethrin and lindane have historically been considered the standard treatments for head lice and scabies.2,3 Toxicity is low following topical administration of permethrin due to minimal percutaneous absorption.4 However, several jurisdictions have banned lindane due to concerns of neurotoxicity and bone marrow suppression, as well as potential negative effects on the environment (contamination of waste water).5 Furthermore, widespread use of permethrin, pyrethrins/piperonyl butoxide, and lindane has led to resistance and higher rates of treatment failure.6 Resistance patterns and rates to these agents in Canada have not yet been studied.6 Due to concerns surrounding resistance and neurotoxicity, patients and caregivers have searched for alternative treatments.

  • Therapeutic Class Overview Scabicides and Pediculicides
    Therapeutic Class Overview Scabicides and Pediculicides Therapeutic Class Overview/Summary: The agents indicated for the management of scabies and head lice are listed in Table 1. The skin and mucous membrane scabicides and pediculicides are approved to treat pediculosis and scabies.1-10 Pediculosis is a transmissible infection, which is caused by three different kinds of lice depending on the location: head (Pediculus humanus capitis), body (Pediculus humanus corporis) and pubic region (Phthirus pubis). Pediculosis is often asymptomatic; however, itching may occur due to hypersensitivity to lice saliva.11 Scabies is also a transmissible skin infection caused by the mite Sarcoptes scabiei. Mites burrow into the skin and lay eggs, which when hatched, will crawl to the skin’s surface and begin to make new burrows. The most common clinical manifestation of scabies is itching, which is due to a hypersensitivity reaction to the mite or mite excrement.12 When treating scabies and lice, the goal of therapy is to eradicate the parasite. Benzyl alcohol inhibits lice from closing their respiratory spiracles, which causes the lice to asphyxiate.3 Crotamiton has scabicidal and antipruritic actions; however, the exact mechanism of action is unknown.4 Lindane is a central nervous system stimulant, which causes convulsions and death of the arthropod.1,2 Malathion is an organophosphate agent, which inhibits cholinesterase activity.5 Permethrin disrupts the sodium channel current, which leads to delayed repolarization and paralysis of the arthropod.1,2 Spinosad causes neuronal excitation, which leads to paralysis and death.6 The suspension also contains an unspecified amount of benzyl alcohol.

The toxic effect of permethrin and cypermethrin on engorged Ixodes ricinus females. Ann Agric Environ Med. 2014; 21(2): 259–262. doi: 10.5604/1232-1966.1108587 Abstract Introduction. Ixodes ricinus tick is of great medical and veterinary importance and has a wide range of geographical distribution. The study presents the effect of permethrin (Per) and cypermethrin (CM) on engorged I. ricinus females. Materials and method. The effect of perythroids studied on engorged I. ricinus females was assessed on the basis of the pre-oviposition and oviposition period. Remote effects of Per and CM application were assessed by investigation of the length and course of embryonic development and larval hatching from eggs laid by pyrethroid-treated females. Per (Copex WP) was used at doses of 0.78125–25.0 µg/1 specimen, and CM (Kordon 10WP) was applied at 0.3125–10.0 µg/1 specimen. Immediately after the feeding period, I. ricinus females were sprayed with 20 µl of a pyrethroid solution and kept at 28 °C and 75%RH. Results. The experiments demonstrated that CM exerted a stronger toxic effect on I. ricinus females than Per. The lowest doses of CM doubled the length of the pre-oviposition period while its highest doses prolonged the period nearly three times compared with the control.

They have been found to be relatively safe for humans and animals. Pyrethroids are recommended for personal protection against malaria and virus Zika by the World Health Organization. Pyrethroids act on voltage-gated sodium channels, which cause an influx of sodium ions into the nerve cells and permanent depolarization. They also influence activities of enzymes, especially in nerve and liver cells. Contact of pyrethroids with the skin, digestive tract, and respiratory tract results in their penetration into the body. Due to the importance of the subject, a summary of the current state of knowledge on the toxic effects of pyrethroids was presented in the comprehensive review by Chrustek et al, published in journal Medicina. Particular attention was paid to nephrotoxic, hepatotoxic, cardiotoxic, immunotoxic, neurotoxic, and behavioral effects of pyrethroids on human and animal bodies.

    DOSAGE AND ADMINISTRATION Apply a thin layer of Lindane Lotion over all skin from the neck down. One ounce is sufficient for an average adult. Do not prescribe more than 2 ounces for larger adults. Apply only once. Wash off in 8 to 12 hours. Do not retreat. (See boxed WARNINGS.) Patients should be provided specific information on use of product. (See PRECAUTIONS: Information for Patients and the Medication Guide.) Patients should be instructed on proper use of Lindane Lotion, especially the amount to apply, how long to leave on and the need to avoid retreatment. Patients should be informed that itching occurs after the successful killing of scabies (lice) and continued itching is not necessarily an indication for retreatment with Lindane Lotion. A Lindane Lotion Medication Guide must be given to the patient each time Lindane Lotion is dispensed, as required by law. The Lindane Lotion Medication Guide is an important part of the risk management program for the patient. HOW SUPPLIED Lindane Lotion, USP 1% is supplied in patient-size 2 fl oz (60 mL) bottles.
