Drug Name Allopurinol

In both the hypophysis and hypothalamus there are cortisol receptors through which cortisol can exert a feedback inhibition of ACTH or CRH release. By means of these cortisol “sensors,” the regulatory centers can monitor whether the actual blood level of the hormone corresponds to the “set-point. ”
Ideal properties of ODTs The performance of ODTs depends on the technology used during their manufacture. The necessary property of such tablets is the ability to disintegrate rapidly and disperse or dissolve in saliva, thereby obviating the need for water. Various technologies have been developed that enable ODT to perform this unique function.

 

As a prerequisite, the drug must have affinity for the carrier (blue triangle matching recess on “transport system”) and, when bound to the latter, be capable of being ferried across the membrane. Membrane passage via transport mechanisms is subject to competitive inhibition by another substance possessing similar affinity for the carrier.
When the system has high spontaneous activity, the antagonist may cause an effect that is the opposite of that of the agonist: inverse agonist. A “true” antagonist lacking intrinsic activity (“neutral antagonist”) displays equal affinity for both the active and inactive states of the receptor and does not alter basal activity of the cell.
