Abstract

fetched live from OpenAlex

Finasteride is used to treat benign prostatic hyperplasia (BPH) and pattern hair loss (androgenetic alopecia or APA). The local administration of formulations with increased solubility and controlled release of finasteride are proposed using gallate-containing compositions within embolic microparticles or paste. Finasteride solubility in either epigallocatechin gallate (EGCG) or tannic acid (TA) solutions was assessed using HPLC. Poly(dl-lactide-co-glycolide) (PLGA) or poly(methylmethacrylate) (PMMA) microspheres (100-400 μm) containing finasteride and EGCG or TA were effectively manufactured. Embolic particles were loaded with finasteride/EGCG/TA. Dermal uptake of TA/EGCG/finasteride topical compositions was measured in pig skin. The solubility of finasteride was dramatically increased using EGCG- or TA-based compositions. Finasteride loaded microspheres released over two months which was increased by EGCG or TA inclusion. Embolic particles soaked up finasteride and EGCG or TA and released the encapsulated drug over two weeks. Dermal uptake of finasteride from EGCG- or TA-based formulations was enhanced between 10 and 50 fold in layers as deep as 500 μm when compared to a generic control formulation. Gallate-based formulations of finasteride increase drug solubility and allow for effective release of the drug from embolic formulations. Paste or powder EGCG- or TA-based formulations of finasteride greatly increase dermal penetration of the drug.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
