Source:
Synthesized from cholic acid obtained fromfrom cattle sources or
Synthesized from steroid sapogenins (diosgenin) obtained from plants
Disposition:
Oral administration; complete absorption
Metabolized similar to endogenous steroids
Molecular alterations given rise to differences in:
Affinity for mineralocorticoid or glucocorticoid receptors
Extent of protein binding
Stability
Spectrum of metabolic products
Prodrugs may be used (prednisone is converted to prednisolone)
Similar to those of cortisol (endogenous agents)
