Spotlight Commentary: Importance of Dose Redefining in the Process of Drug Repurposing

Minoxidil was applied to a single miniaturized hair follicle over four months, resulting in less miniaturization but not yet terminal growth. The user used a 5% minoxidil solution, specifically the Regaine brand, and observed changes using a handheld WiFi microscope.

High-dose oral minoxidil (>5 mg/day) can increase hair density in some men with androgenetic alopecia, but side effects like extra body hair and heart issues are common. Gradual dose increase is advised, but adverse effects may lead to discontinuation or dose adjustments.

A new extended-release oral minoxidil formulation claims to improve hair growth by maintaining steady blood levels, reducing side effects like hypotension, and potentially benefiting female hair loss. However, it is not considered groundbreaking as it builds on existing minoxidil treatments, and its effectiveness compared to current doses is debated.

Low-dose oral minoxidil shows mixed results, with some users experiencing hair regrowth and others seeing no significant change. Finasteride is also commonly used, often in combination with minoxidil, and is generally considered effective with a low rate of side effects.

Minoxidil, finasteride, and RU58841 are discussed as treatments for hair loss, with excitement around a new drug, PP405, and a reformulated oral minoxidil in trials. Concerns about cost, side effects, and long-term use are also mentioned.

VDPHL01, an extended-release oral minoxidil tablet, showed promising results in improving hair coverage for 79 to 86% of men in a trial, with fewer side effects compared to standard doses. Many users prefer oral minoxidil over topical due to ease of use and fewer side effects, especially for those with pets.
