High penetration compositions (HPC) of a parent compound, which are capable of crossing biological barriers with high penetration efficiency. The HPCs are capable of being converted to parent drugs or parent drug-related compounds such as metabolites after crossing one or more biological barriers and thus can render treatments for the conditions that the parent drugs or parent drug-related compounds can. Additionally, the HPCs are capable of reaching areas that their parent drugs or parent drug-related compounds may not be able to access or to render a sufficient concentration at the target areas HPCs of NSAIA, for example, have demonstrated indications such as treating hair loss. A HPC can be administered to a subject through various administration routes, e.g., locally delivered to an action site of a condition with a high concentration or systematically administered to a biological subject and enter the general circulation with a faster rate.

Amines and amine derivatives that improve the buffering range, and/or reduce the chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules to form polyamines with differing pKa's will extend the buffering range, derivatives that result in polyamines that have the same pKa yields a greater buffering capacity. Derivatives that result in zwitterionic buffers improve yield by allowing a greater range of stability.
