Alice Lotion, manufactured by Square Pharmaceuticals Ltd., is a topical antiparasitic treatment formulated with Ivermectin BP 0.5%. It is specifically indicated for the treatment of head lice infestations in individuals aged 6 months and older. Ivermectin works by binding selectively to glutamate-gated chloride channels in the nerve and muscle cells of parasites, leading to their paralysis and death. This mechanism effectively eradicates lice and their eggs, providing relief from infestations.
