Regulation exerting influence

A distinction should be made between the different levels of political influence operating at different levels of policy. At the macro level, the body politic is regarded as representative of the public or the electorate. Hence, politics is a means by which society decides which regulatory direction is ethically acceptable, socially preferable, economically beneficial and scientifically reliable. From the perspective of representative democracy, therefore, it is desirable for politics to determine the overall legal frameworks within which dmgs are regulated. But at the micro level, where decisions are made which apply those legal frameworks to specific cases, it is not desirable for politics to exert influence on individual cases. 

Serotonin has been shown to have the strongest association with mood regulation norepinephrine has more influence on the brain s hormonal response and dopamine is correlated most often with reward-mediated behavior (Figure 1.6). However, it must be noted that neurotransmitters exert influence over many different aspects of neuronal function. 

Regulatory or allosteric enzymes like enzyme 1 are, in some instances, regulated by activation. That is, whereas some effector molecules such as F exert negative effects on enzyme activity, other effectors show stimulatory, or positive, influences on activity. 

The consumer movement, particularly the Consumers Health Fomm, also has considerable political influence. As a result of political pressure exerted by HIV/AIDS pressure groups and industry, the DRA was reviewed, new legislation introduced and new committees established to ensure that the regulatory authority responded more efficiently to public and political needs. Professional associations, especially the Pharmacy Guild of Australia, have traditionally played an active role in decisions related to pharmaceutical regulation. The Australian Pharmaceutical Advisory Council was established by the Australian Government to advise the Commonwealth Minister for Health on pharmaceutical policy. 

In terms of the influence exerted by the public and the private sectors on dmg regulation, these 10 countries can be placed along a continuum, as depicted in Figure 3.3 below. Cuba, where the Government has exclusive power over regulatory decisions, is at one extreme, and Australia, where consumers and the pharmaceutical industry have official representation and make recommendations to the TGA, at the other. 

GC exert their regulatory effects on the HPA system via two types of corticosteroid receptors the glucocorticoid receptor (GR) and the mineralocorticoid receptor (MR) (Reul and De Kloet 1985). GRs occur everywhere in the brain but are most abundant in hypothalamic CRH neurons and pituitary corticotropes. MRs, in contrast, are highly expressed in the hippocampus and, at lower expression levels, in hypothalamic sites involved in the regulation of salt appetite and autonomic outflow. The MR binds GC with a tenfold higher affinity than does the GR (Reul and De Kloet 1985). These findings on corticosteroid receptor diversity led to the working hypothesis that the tonic influences of corticosterone...
