Factors Affecting Drug Response: Overview01:21

Factors Affecting Drug Response: Overview

2.0K
When it comes to infants and young children, they are typically administered smaller doses of medication in comparison to adults. This is primarily because their organ functions still need to fully develop, meaning their bodies are not as efficient at metabolizing or eliminating drugs. Additionally, their blood-brain barrier is more permeable than in adults. As a result, high concentrations of drugs can easily penetrate the central nervous system (CNS), potentially leading to neurological...

Drug Dosage Regimen: Overview01:15

Drug Dosage Regimen: Overview

3.5K
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...

Routes of Drug Administration: Overview01:22

Routes of Drug Administration: Overview

6.2K
Drug administration involves delivering drugs to the body through various routes, such as enteral, parenteral, and topical.
Enteral administration refers to drugs absorbed through the gastrointestinal tract. They can be swallowed (perorally), placed under the tongue (sublingually), or on the inner lining of the cheeks (buccally). Perorally administered drugs take time to be absorbed and have a slower onset of action. The rectal route is another form of enteral administration, which allows for...

Factors Influencing Drug Absorption: Disease States and Pharmacology01:25

Factors Influencing Drug Absorption: Disease States and Pharmacology

516
Multiple disease states can significantly influence the oral drug absorption process by affecting blood flow and the functionality of the gastrointestinal (GI) system. Various GI diseases, including conditions that alter GI motility, such as diarrhea, decreased acid secretions (achlorhydria), and infections, have been associated with reduced drug absorption.
Substances such as alcohol and specific drugs, including antineoplastics, can also negatively impact drug absorption. For instance,...

Drug Delivery: Overview01:16

Drug Delivery: Overview

294
The selection of a drug's delivery route depends upon its physicochemical properties, including lipid or water solubility and ionization, as well as the therapeutic requirement, such as immediate or sustained effect. These routes can be divided into three primary categories: enteral, parenteral, and topical.
Enteral delivery involves administering drugs directly through swallowing, sublingual placement, or buccal application. Orally administered drugs predominantly navigate the...

Factors Affecting Drug Distribution: Miscellaneous Factors01:19

Factors Affecting Drug Distribution: Miscellaneous Factors

338
Drug distribution in the human body is a complex process influenced by various individual factors, including age, pregnancy, obesity, diet, body water composition, pH levels, and specific disease conditions.
Age plays a significant role due to differences in body composition among different age groups. Infants, for instance, have a higher proportion of total body water and lower albumin levels, a protein that binds drugs in the bloodstream. This unique composition in infants enhances the...

Area of Science:

  • Public Health
  • Epidemiology
  • Health Policy

Background:

  • Designing effective mass drug administration (MDA) campaigns is critical for disease control.
  • Optimal coverage depends on understanding and addressing contextual factors influencing intervention uptake.

Approach:

  • A comprehensive literature review was conducted to identify factors affecting MDA delivery.
  • 37 articles detailing contextual factors and 13 with modeling data were analyzed.

Key Points:

  • Participant acceptability, particularly concerns about adverse events, significantly impacts MDA uptake.
  • Feasibility issues, including drug delivery logistics and addressing specific populations (e.g., pregnant women), are vital.
  • Cost analysis reveals drug prices as a primary driver, with potential savings through integrated delivery.

Conclusions:

  • An evidence gap exists regarding the direct assessment of values and health equity in MDA programs.
  • Successful MDA program design necessitates careful consideration of programmatic goals, participant values, and the broader sociopolitical and economic context to ensure equitable access and success.
