Drug Name Protonix

Agents active against blood schizonts do not prevent the (symptom-free) hepatic infection, only the disease-causing infection of erythrocytes (“suppression therapy”). On return from an endemic malaria region, a 2 wk course of primaquine is adequate for eradication of the late hepatic stages (P. vivax and P. ovale).
In pacemaker fibers, diastolic depolarization is hastened, so that the firing threshold for the action potential is reached sooner (positive chronotropic effect, B). The cardiostimulant effect of ?-sympathomimetics such as epinephrine is exploited in the treatment of cardiac arrest. Use of ?- sympathomimetics in heart failure carries the risk of cardiac arrhythmias.

 

G-proteins can undergo lateral diffusion in the membrane; they are not assigned to individual receptor proteins. However, a relation exists between receptor types and G-protein types (B). Furthermore, the ?-subunits of individual G-proteins are distinct in terms of their affinity for different effector proteins, as well as the kind of influence exerted on the effector protein.
Researchers have formulated ODT for various categories of drugs used for therapy in which rapid peak plasma concentration is required to achieve the desired pharmacological response.
