TLDR Oral itraconazole effectively reaches and treats deep skin layers in guinea pigs.
The study investigated the distribution of orally administered 3H-labeled itraconazole in guinea pigs. After dosing the animals with 10 mg/kg/day for 2 days, autoradiography revealed that itraconazole accumulated in the epidermis, hair follicles, sebaceous glands, dermal fat, and hypodermal muscle tissue at 6, 24, and 48 hours post-administration. However, by 96, 168, and 336 hours, the drug's presence decreased to background levels. These findings supported the effectiveness of oral itraconazole in targeting deeper skin layers to eradicate infective organisms.
