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.

Effect of high-fat meal intake on the pharmacokinetic profile of ivermectin in Japanese patients with scabies.

Ivermectin (IVM) is used as an anthelmintic agent in many countries. To evaluate the effect of high-fat (HF) meal intake on the pharmacokinetics of IVM, a clinical trial was conducted in Japanese patients with scabies. The patients were administrated Stromectol(®) tablets in the fasted state, and after 1 week they were also administrated it after a HF meal (fed state).

Experimental study of pharmacokinetics of external, whole-body bathing application of ivermectin.

As a novel method improving the safety of conventional oral ivermectin (IVM) for scabies treatment, we conceived an idea called the "whole-body bathing method". In this method, the patients would bathe themselves in a bathing fluid containing IVM at an effective concentration. To evaluate the feasibility of the method, we investigated the IVM concentration in the skin and plasma after bathing rats in a fluid containing 100 ng/mL of IVM.
