Pharmacological efficacy

Efficacy pharmacology Evaluation of a drug s characteristics, effects, and uses with regard to the target illness, and its interactions with living organisms. [Pg.772]

Safety pharmacology generally uses larger group sizes than efficacy pharmacology, and it is important that the results are sufficiently reliable for regulatory decisions to be made. However, in some circumstances, methods exist to reduce animal use while at the same time maintaining scientific validity. One example is... [Pg.17]

In 2001, general pharmacology data have been classified in efficacy pharmacology, secondary/ safety pharmacology, and other pharmacology . All pharmacological studies should also comply with the GLP standards. [Pg.499]

The routine research of active fractions or active components from Chinese herbal medicine includes repeated extraction, separation, and bioactivity screening. The whole process is tedious, laborious, and expensive. Clearly, it would be difficult to predict the fate of these active components when they undergo the study of efficacy, pharmacology, and metabolism. Perhaps another point of view would be to consider how the human body reacts to a drug and the subsequent analysis of metabolism of active fractions or active components. This perspective may allow for novel studies on therapeutic basis of Chinese herbal medicine and result in breakthroughs in medicine. [Pg.581]

The mechanism of action of nootropic agents has been proposed to be their abiUty to faciUtate information acquisition, consoHdation, and retrieval (36). No one particular effect has been observed with any consistency for these agents, thus whereas a considerable amount of diverse preclinical pharmacological behavioral data has been generated using these compounds, the significance of these results in predicting clinical efficacy has not been established (43,44). Reviews on the biochemical and behavioral effects of nootropics are available (45—47). [Pg.95]

The therapeutic efficacy of a dmg is generally measured in terms of ED q or ID q which represent the concentration of dmg which produces 50% of the maximum effect or 50% of maximum inhibition. LD q represents the concentration of dmg that produces 50% fataUties in test animals. The therapeutic index is the ratio of the ED q versus LD q. Detailed descriptions of the terminology and fundamental principles of pharmacology are available (32) (see Pharmacodynamics). [Pg.239]

Doxepin [1668-19-5] (38), unlike other commercially available tricyclics, has an oxygen atom in the bridge between the two aromatic rings. It is marketed as a cis—trans mixture (1 5) of isomers, both of which are active. This close relative of amitriptyline (33) has both sedative and anxiolytic properties associated with its antidepressant profile. Maprotiline [10262-69-8] (39) and amoxapine [14028-44-5] (40) are pharmacologically, although not chemically, similar to the tricycHc secondary amines. Clomipramine [303-49-1] (41) has similar pharmacological and antidepressant efficacy. However, clomipramine is approved by the U.S. FDA only for the treatment of obsessive—compulsive disorder. Representative brands of tricycHc antidepressants marketed in the United States are Hsted in Table 2. [Pg.468]

Cardiac arrhythmias are an important cause of morbidity and mortality approximately 400,000 people per year die from myocardial infarctions (MI) in the United States alone. Individuals with MI exhibit some form of dysrhythmia within 48 h. Post-mortem examinations of MI victims indicate that many die in spite of the fact that the mass of ventricular muscle deprived of its blood supply is often quite small. These data suggest that the cause of death is ventricular fibrillation and that the immediate availability of a safe and efficacious antiarrhythmic agent could have prolonged a number of Hves. The goals of antiarrhythmic therapy are to reduce the incidence of sudden death and to alleviate the symptoms of arrhythmias, such as palpitations and syncope. Several excellent reviews of the mechanisms of arrhythmias and the pharmacology of antiarrhythmic agents have been pubflshed (1,2). [Pg.110]
