The drug burden index demonstrates that anticholinergic and sedative drug exposure is associated with poorer function in community-dwelling older people and provides a useful evidence-based tool for assessing the functional effect of exposure to medications in this population.
Effect of Obesity on the Pharmacokinetics of Drugs in Humans

Clinicians should design treatment regimens that account for any significant differences in the CL and Vd in the obese, using a size descriptor that corrects for differences in absolute CL between obese and non-obese individuals.
Pharmacokinetics and Clinical Effectiveness of Methylphenidate

It is difficult to predict which children will have a favourable response to methylphenidate, and therefore dosage must be titrated for optimal effect and avoidance of toxicity in each child, and further studies of the relationship between the pharmacokinetic and pharmacodynamic properties are required to allow the development of optimal dosage regimens.
Effect of Age, Gender, and Obesity on Midazolam Kinetics

Midazolam elimination half‐life (t1/2) after iv dosage was significantly prolonged in elderly (aged 60‐74 yr) versus young (24‐33 yr) males and in obese subjects (8.4 vs. 2.7, P < 0.001) and Vd was greater in the obese subjects even after correction for total weight, indicating disproportionate distribution of midAZolam into adipose weight.

It is confirmed that nitrite reduction at reduced oxygen pressures is a major source for red cell NO and the formation and potential release from the red cell of this NO could have a major impact in regulating the flow of blood through the microcirculation.
Caloric restriction and intermittent fasting alter spectral measures of heart rate and blood pressure variability in rats

The results suggest an additional cardiovascular benefit of DR that merits further studies of this potential effect in humans, and alter spectral measures of heart rate and blood pressure variability in rats.

It is concluded that some existing highly selective methods for food protein measurement have potential for routine quality control, but their successful implementation will require matrix-specific validation and the use of supporting reference materials.
High‐Risk Prescribing and Incidence of Frailty Among Older Community‐Dwelling Men

High–risk prescribing may contribute to frailty in community–dwelling older men and the Drug Burden Index, a dose–normalized measure of anticholinergic and sedative medicines, in 1,662 men ≥70 years of age.
Physical and Cognitive Performance and Burden of Anticholinergics, Sedatives, and ACE Inhibitors in Older Women
- Y.-J. Cao, DE Mager, D. Abernethy
- MedicineClinical pharmacology and therapy
- 1 March 2008
The risk associated with exposure of vulnerable older women to drugs with anticholinergic properties, and to a lesser extent those with sedative properties, implies that such drugs should not be used in this patient group without compelling clinical indication.

Higher Drug Burden Index is associated with poorer physical performance and functional status in community-dwelling older Australian men.
