The SX suffix on this label runs across a whole family of Indian sexual-health generics, jellies and tablets alike. Underneath it is plain tadalafil: four film-coated tablets at 20 mg each.
Tadalafil is a selective inhibitor of phosphodiesterase type 5. It carries no hormonal or androgenic activity whatsoever, which places it a long way from anything in the steroid part of the catalogue, and the same molecule is prescribed in urology for prostate enlargement. This four-tablet carton is the compact version of the brand; the identical tablets also come in larger strips.
