March 1991 in “Endocrinology” This study in rats suggests that combining the 5 alpha-reductase inhibitor 4-MA with the antiandrogen Flutamide may enhance prostate cancer therapy by additively inhibiting prostatic growth and mRNA levels of androgen-sensitive prostatic binding proteins.
December 2025 in “Molecular Pharmaceutics” In this study, researchers developed a coamorphous form of tadalafil and finasteride, showing improved solubility and dissolution in vitro, with results successfully translated in vivo in rats. They reported reasonable stability, suggesting this form could serve as a therapeutic alternative to the current marketed combination.
