    The Biopharmaceutics Classification System (BCS) is a system to differentiate drugs on the basis of their solubility and permeability. [1] This system restricts the prediction using the parameters solubility and intestinal permeability. The solubility classification is based on a United States Pharmacopoeia (USP) aperture.

  9. Product lifetime - Wikipedia

    en.wikipedia.org/wiki/Product_lifetime

    Product lifetime or product lifespan is the time interval from when a product is sold to when it is discarded. [1] Product lifetime is slightly different from service life because the latter considers only the effective time the product is used. [1] It is also different from product economic life which refers to the point where maintaining a ...
