OTC NCT05643820 ↗ Comparison of Oral Ivermectin and Permethrin 5% Lotion in Treatment of Pediculosis Capitis Completed Combined Military Hospital Abbottabad Phase 1 2022-03-01 In children, pediculosis is a common ectoparasitic infestation. Infestation of head lice (Pediculus humanus capitis) causes a variety of physical symptoms, including pruritus, excoriation, cervical lymphadenopathy, and conjunctivitis1. It also has a number of negative social consequences, including parental anxiety and stigmatization of infested children2. It is a significant public health issue that primarily affects school-aged children aged 8 to 113. In developing nations, prevalence rates of up to 40% have been reported4. The four urban areas of KPK (NWFP) reported prevalence of 36.7%5. People with a low socioeconomic background and poor hygiene are more likely to be affected6. Pediculosis capitis has been treated using a variety of treatment modalities. They include both physician prescription and over-the-counter medications. Permethrin or ivermectin had been used topically or orally. Permethrin is a neurotoxin that is synthesized. It is a pyrethroid neurotoxic that targets voltage-sensitive Sodium ion receptors in the neurological system of the insect, triggering nerve depolarization, hyperexcitation, muscular paralysis, and, eventually, parasite death7. Ivermectin is antiparasitic medication, it is possible to treat diseases like lymphatic filariasis, and ectoparasite infestations, primarily scabies, with ivermectin because it binds to glutamate gated chloride ion receptors of invertebrates and disrupts neurotransmission8. The rationale of this study is to study while comparing effectiveness of oral ivermectin and topical permethrin in management of pediculosis. The topical medication usage is problematic and had reported drug resistance9. There has been less regional or national research on the effectiveness of oral Ivermectin, so doctors less frequently use it in our department. Instead, the patients are treated for pediculosis capitis with topical Permethrin.

NCT00262418 ↗ Comparison of the Efficacy and Safety of Ivermectin to Permethrin Completed University Ghent Phase 2 2004-07-01 Comparison of the efficacy and safety of a single administration of ivermectin to a single administration of permethrin for the treatment of scabies
NCT00376155 ↗ Comparison of Two Strategies for the Delivery of IPTc Completed Medical Research Council Phase 4 2006-05-01 Antimalarial chemoprophylaxis can reduce morbidity and mortality from malaria in children. However, this approach to malaria control has not been implemented widely because of concerns over its possible effect on the development of resistance and natural immunity. Intermittent preventive treatment (IPT) may be able to achieve some of the beneficial effects of chemoprophylaxis without its drawbacks. Recently, it has been shown that IPT given to Senegalese children under the age of five years on three occasions during the malaria transmission season reduced the incidence of clinical malaria by approximately 90%. However, it is uncertain how this intervention can be most effectively delivered. Therefore, 26 Maternal and Child Health (MCH) trekking clinics in Upper River Division, south of the River Gambia, each with an average catchment population of 400-500 children under 5 years of age, will be randomly allocated to receive IPT from the MCH trekking team or from a IPT dispenser (village health worker, traditional birth attendant or a community mother based in a primary health care village). Treatment with a single dose of sulfadoxine /pyrimethamine (SP) plus three doses of amodiaquine will be given to all study subjects at monthly intervals on three occasions during the months of September, October and November. The primary end points will be the incidence of clinical attacks of malaria detected by passive case detection, and cost-effectiveness of the delivery methods. Important secondary endpoints will be the coverage and the equity of coverage of IPT in preventing malaria morbidity.
