Case series of elderly patients with scabies topically applied with ivermectin via whole-body bathing.

As a novel method of ivermectin (IVM) administration for the treatment of scabies, we devised a whole-body bathing (WBB), in which patients are immersed in a fluid that contains IVM. A multi-institutional trial for elderly patients with scabies was conducted to investigate the efficacy and safety of IVM-WBB. Seven elderly patients with scabies were enrolled and received IVM-WBB up to four times at 1-week interval.

Pharmacokinetics of ivermectin applied topically by whole-body bathing method in healthy volunteers.

As a novel administration method of ivermectin (IVM) for scabies treatment, we proposed a "whole-body bathing method (WBBM)". In this method, the patients would bathe themselves in a bathing fluid containing IVM at an effective concentration. Previously, we demonstrated that WBBM could deliver IVM to the skin but not to the plasma in rats.
