I think that tretinoin works even without minoxidil, I am wrong ?
At really lower doses, fevipiprant was more effective, much more, than Setipiprant in Asthma . For me, is like comparing something even weaker than saw palmeto to dutasteride.
Lets put this for example, We know that DHT cause hair loss, what about a drug that will only inhibit 30 % of the systemic DHT ( compare to 70 % finasteride, almost 100 % of dutasteride ) it should work ? For me, setipiprant have to be see it in this way.
Hi James,
I think you are right, but I am not sure. It seems the PTGDS angle is still alive, but I wonder if any company will pursue it. Maybe inhibiting PTGDS is too unsafe. Or hard to do. I don't know. Here is the quote from a 2/2019 study for those that have not seen it yet "It has been suggested that inhibitors of PTGDR2 may reverse hair growth through inhibition by PGD2 activity[6]. A multicenter, randomized, double -blind, placebo -controlled, Phase 2A study of setipiprant (oral PTGD2 receptor antagonist) 500 mg tablets BID in Androgenetic Alopecia is being performed (ClinicalTrials.gov Identifier: NCT02781311). It is interesting that this receptor is not overexpressed in our patients. Perhaps research on treatment should focus on drugs that target PTGDS activity and not PTGDR2."
