Sequential Release Formulation for Multi-Factor Hair Growth
Sequential release systems must overcome significant diffusion barriers to maintain therapeutic levels of multiple growth factors. In controlled trials, initial burst releases can reach 60-70% of loaded cargo within the first 24 hours, followed by sub-therapeutic delivery rates thereafter. The co-delivery challenge becomes particularly pronounced when multiple bioactives have distinct physicochemical properties and stability requirements—requiring carrier systems that can maintain distinct release profiles within a single formulation.
The fundamental challenge lies in engineering delivery systems that can release multiple bioactive agents with independent kinetics while preserving their structural integrity and biological activity.
This page brings together solutions from recent research—including dual-modifier excipient systems for sustained polyamine delivery, liposome-encapsulated peptide-exosome complexes from adipose-derived stem cells, controlled-release CNP agonist formulations, and silk protein stabilization techniques for growth factor preservation. These and other approaches demonstrate how sequential delivery challenges can be addressed to maximize therapeutic efficacy while minimizing off-target effects.
