While zafirlukast is generally well tolerated, headaches and stomach upset often occur. Some rare side effects can occur, which can be life-threatening, such as liver failure. eosinophilic granulomatosis with polyangiitis has ...
Dissociation constant. In chemistry, biochemistry, and pharmacology, a dissociation constant (KD) is a specific type of equilibrium constant that measures the propensity of a larger object to separate (dissociate) reversibly into smaller components, as when a complex falls apart into its component molecules, or when a salt splits up into its ...

The dose–response relationship, or exposure–response relationship, describes the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time. [ 1 ] Dose–response relationships can be described by dose–response curves.
In pharmacology, potency or biological potency[1] is a measure of a drug's biological activity expressed in terms of the dose required to produce a pharmacological effect of given intensity. [2] A highly potent drug (e.g., fentanyl, clonazepam, risperidone, benperidol, bumetanide) evokes a given response at low concentrations, while a drug of ...
