They would have made it soluble for when tested on murine when administered intravenously as would have been injected via a syringe. By injection one can be very precise with amount of solute and weight of mouse.
From memory ADME was very good at the time. ie adsorption, distribution, metabolism and excretion.
However, by the oral route I take it we are meaning the ingestion of a solid and not a liquid. How consistent is the passing of a tablet through the gastro intestinal tract and how effective is its dissolution? We still need a solute ie what is left after a material has dissolved, then a solution is formed and after solution what remains is a solute and hopefully very little or no precipitate of the chemical. If all is well with the production of the solute then this can be used to measure absorbtion ie uptake via the solute passing through the capillary lining of the stomach. From the time you take the tablet, the tablet when entering the stomach needs to dissolve, Effects of uptake will be very different if taken on an empty stomach or with food.
Can we take this FLT tablet and administer like paracetamol with the 'I will have a couple now and one or two before I go to bed attitude'. No good this way if we do, as we need to know mol/s exact mol/g of solute and how efficient is the uptake of the drug when taken orally, more to establish a safety profile than anything else'
All appears very simplistic when in fact it is not.
I am sure the Chinese will overcome these hurdles.
That is the best I can understand if it is a solution problem.
A bit basic I know but, that is my understanding of the solution to the solute.
regards to the happy, the unhappy and all the rest.
