hi ,
i'm sorry to bother you but i have a question that i have tried to get an answer for years but no Doctor in my country were able to o answer me properly and i needed your expert opinion on that subject.
my question is a bit technical and is about the rate of absorption of topical vs oral
- indeed, if you're a good responder to topical do you get more minoxidil in your bloodstream by using 5 mg of oral min or using 12 ml of topical 5% per day ?
that's the dosage i'm using currently i'm applying 6 ml in the morning and 6 ml at night right before to go to bed so i get more than the required 4 hours that allows 75% of the dose to be absorbed properly and i'm appllying it all over my entire scalp ( hairline / crown / midscalp / donor zone / sides of the head) so there is no saturation or buildup of minoxidil in only one area of the scalp that would cause saturation and prevent the minoxidil from going systemic ( i'm trying to get the most systemic absorption possible to compare if my theory is true or not) .
i do apply such massive dosage with no health related sides whatsoever an i don't mind doing so)
Now , according to studies and the original rogaine data sheet Systemic absorption of minoxidil from topically applied solution ranges between 1% and 2% of the total applied dose
so let's say
ay i'm an hyper responder to topical min ( which i definitely am) and i get 2% of the applied dose :
the standard version with propylene glycol and ethanol of the topical 5 % minoxidil contains 50 mg of minoxidil per ml so if absorb in the bloodstream 2% of 50mg of minoxidil each time i apply 1 ml of topical minoxidil i get 1 MG of minoxidil going systemic ( 2% of 50 mg equal 1 mg if my calculs is correct)
now because i apply 12 ml of 5 % per day i get 12X this dose so according to those studies i should get 12 mg of minoxidil going in the bloostream just by using the topical which is superior in theory to using the 5mg pills orally so i'm really confused .
or maybe it works in a totally different way and using and 5 mg is superior and goes more systemic than even using 1000ml of topical per day i hav no idea .
i also found that graph ( linked file below) on dr donovan blog extracted from a previous study on minoxdil rate of absorption in the bloodstream and it shows most ppl only get a concentrations under 2ng/ml of minoxidil in the blood after using 1ml of topical min daily whereas using 5 mg you get a concentration of 156.6 ng /ml .
HOWEVER acording to that quote from the study top tier reponder to topical min 5 % ( which i am definitely ) gets up to 21ng/ml in the bloodtream by using only 1 ml of 5% topical so i imagine that someone like me using 12 ml daily is actually gettin up to 252ng/ml which is far superior to the 156.6ng/ml that using 5 mg of ORAL min gives and in that case topical seems to be superior than oral?
i really need your help to figure out.
the quote from the study :
"However, some patients using topical minoxidil occassionally do acheive much higher levels or minoxidil in the blood - even levels up to 21 ng/mL.- See more at: https://donovanmedical.com/hair-blog/oral-minoxidil-top-10#sthash.jT5vM4dj.dpuf
