Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

31
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

The Placebo Effect01:54

The Placebo Effect

6.1K
The placebo effect occurs when people's expectations or beliefs influence or determine their experience in a given situation. In other words, simply expecting something to happen can actually make it happen.

Observational Studies01:11

Observational Studies

8.1K
Observational studies are a type of analytical study where researchers observe events without any interventions. In other words, the researcher does not influence the response variable or the experiment's outcome.
There are three types of observational studies – Prospective, retrospective, and cross-sectional.
Prospective Study
Prospective studies, also known as longitudinal or cohort studies, are carried out by collecting future data from groups sharing similar characteristics. One...

Substance Use Disorders Affecting Sleep01:24

Substance Use Disorders Affecting Sleep

146
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.
Understanding the concepts of physical dependence,...

Assessment of the Cardiovascular System I: Subjective Data

235
A thorough health history and physical assessment are essential for identifying cardiovascular disease (CVD) symptoms and distinguishing them from other health issues.
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...

Drug Abuse and Addiction: Pharmacological Phenomena01:15

Drug Abuse and Addiction: Pharmacological Phenomena

397
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Summary

Increased sedentary time (ST) is linked to higher prescription medication use in adults. Even small increases in daily ST or sedentary bouts significantly raise medication prevalence, highlighting the health risks of prolonged sitting.

Area of Science:

  • Public Health
  • Epidemiology
  • Behavioral Science

Background:

  • Physical activity (PA) is linked to reduced medication use, but sedentary time (ST) is less understood.
  • ST is independently associated with chronic disease and mortality, irrespective of PA levels.
  • Limited research explores ST's direct impact on prescription medication consumption.

Purpose of the Study:

  • To investigate the independent associations between objectively measured ST, sedentary bout patterns, and prescription medication use.
  • To analyze how average daily ST, sedentary bout frequency, and duration relate to medication consumption in adults.

Main Methods:

  • Objective measurement of ST using accelerometers over seven days.
  • Self-reported prescription medication use and types.
  • Poisson regression analysis to determine associations between ST metrics and medication prevalence.

Main Results:

  • Higher daily ST significantly correlates with increased prescription medication use.
  • Each additional hour of ST per day increased medication prevalence by 66%.
  • Each sedentary bout and each minute increase in bout duration were also linked to higher medication prevalence.

Conclusions:

  • Objectively measured sedentary time is independently associated with a higher prevalence of prescription medication use in adults.
  • Reducing sedentary time may be a viable strategy to lower medication consumption.
  • Further research into sedentary behavior interventions is warranted.
