Insights

This meta-analysis reviewed studies on intracellular delivery of antimicrobial agents. Many studies lacked rigorous methods and complete data, hindering clinical translation of these promising drug delivery platforms.

Area of Science:

  • Pharmacology
  • Microbiology
  • Drug Delivery Systems

Background:

  • Intracellular pathogens pose significant treatment challenges.
  • Carrier-mediated delivery systems offer a promising strategy to enhance antimicrobial efficacy against intracellular infections.
  • Evaluating the quality of existing research is crucial for advancing this field.

Purpose of the Study:

  • To assess the trends in research on intracellular delivery of antimicrobial agents.
  • To evaluate the methodological quality and completeness of studies in this area.
  • To identify gaps and limitations hindering clinical translation.

Main Methods:

  • A systematic meta-analysis was conducted.
  • Searches were performed in PubMed, Embase, and reference lists of reviews.
  • Included studies focused on carrier-mediated intracellular delivery and pharmacodynamics (PD) of antimicrobials against intracellular pathogens.

Main Results:

  • 99 studies were analyzed, with bacteria being the most targeted pathogen (62.6%).
  • Significant methodological gaps were identified: 21.2% lacked cell verification, and only 31.3% provided comparative drug data.
  • Many studies (approx. 8%) lacked essential experimental evidence for claimed intracellular delivery.

Conclusions:

  • Current research on intracellular antimicrobial delivery often suffers from poor methodological quality and incomplete data.
  • Improvements in study design, verification methods, and data reporting are essential.
  • Enhancing research rigor will facilitate the clinical translation of novel intracellular delivery platforms for antimicrobial therapeutics.

Drug Delivery: Overview01:16

Drug Delivery: Overview

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...

Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport01:23

Mechanisms of Drug Absorption: Paracellular, Transcellular, and Vesicular Transport

Drugs need to permeate cell membranes to reach their target sites after administration. Orally administered drugs must transcend intestinal epithelial membrane barriers to infiltrate the systemic circulation. Drugs with a molecular weight of less than 500 Daltons diffuse through gaps between neighboring cells, called paracellular pathways.
However, most drugs use the transcellular route, traversing directly through the cell membranes via two mechanisms: passive and active transport. Passive...

Methods for Studying Drug Absorption: In vitro

In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

Drug Delivery: Miscellaneous Routes

Drug delivery methods like oral inhalation, nasal sprays, transdermal patches, eye drops, intravitreal injection,  and rectal administration provide localized effects with reduced toxicity.
Oral inhalation and nasal sprays swiftly transfer drugs across the respiratory epithelium's mucosal layer. Inhaled glucocorticoids and bronchodilators directly target lung conditions such as asthma, while fluticasone nasal spray mitigates allergic rhinitis.
Transdermal patches transport drugs...

Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Combined Effects of Drugs: Synergism01:27

Combined Effects of Drugs: Synergism

Synergism is a useful mechanism where combining two or more drugs is more effective than each constituent used alone. Such combinations are also called supra-additive interactions. The drugs collectively enhance the final therapeutic effect by acting on different targets. Another advantage is that the low dose of each constituent drug is sufficient to achieve the desired effect. This helps reduce the duration of therapy and lower the adverse effects of these drugs.
Such synergistic combinations...
