Potency tests are designed to determine how much of an active drug is in a sample. Stability tests are used to determine an expiration date of a product or a beyond-use date of a preparation. Being able to employ the proper method to determine potency or stability is the key to understanding the difference between potency testing versus stability testing. In order to determine potency, a method...

The development of reliable and clinically relevant potency assays is essential to the practice of safe and effective allergen-specific immunotherapy. Allergen standardization in the United States is based on the establishment of a national reference assigned with a biological potency unit to which manufacturers' products are compared using validated relative potency assays. This ensures, at le...

The ideal antihistamine would optimize both receptor and clinical pharmacology, combining high receptor affinity, reflected by high potency, with outstanding clinical efficacy.
