Document Summary
Therefore, their values are reported in meq: example: atomic weight of calcium is 40. Stability: not only refers to the active ingredient present in the product but also includes the excipients, containers and storage conditions, usp"s definition of stability of a pharmaceutical product: Extent to which a product retains, within specific limits, and throughout it"s period of storage and use, the same properties and characteristics that it possessed at the time of manufacture. Incompatibility: describes preventable physical and chemical reactions that can be minimized or eliminated through the use of corrective measures, all incompatibilities should be resolved when designing the formulation, temperature. Increasing concentration has no influence on percentage decomposition. Some substances absorb water readily and liquefy to give a jelly like appearance: may absorb water ad support microbial growth, microbial growth. Sometime ph adjustment used to improve solubility may result in antimicrobial (benzoic acid, parabens) or sweetener (sodium.
