Source: Madeline Lassche, MSNEd, RN and Katie Baraki, MSN, RN, College of Nursing, University of Utah, UT Oral medications are the route most preferred by patients and are one of the most commonly used routes of medication administration by providers. Most oral preparations are taken by mouth, swallowed with fluid, and absorbed via the gastrointestinal tract. Oral medications are available in solid forms (e.g., tablets, capsules, caplets, and enteric-coated tablets) and liquid forms (e.g.,...

Biofilms formed on tooth surfaces are highly complex and exposed to constant innate and exogenous environmental challenges, which modulate their architecture, physiology and transcriptome. We developed a toolbox to examine the composition, structural organization and gene expression of oral biofilms, which can be adapted to other areas of biofilm research.

The following protocol describes a novel method for chronic oral drug administration using an orally dissolving strip (ODS) in lieu of the more commonly used oral gavage method. We demonstrate that preclinical, oral drug delivery using the ODS method represents a safe, convenient, and humane alternative to oral gavage.

Changes in the oral microbiome throughout childhood are of growing interest. Comparison of different microbiome studies reveals a lack of standardized sampling protocols. Limited space makes sampling the sound subgingival sulcus of children challenging. Paper point sampling is presented here in detail as the method of choice for this area.
FAQs
Once swallowed, a tablet, capsule, or liquid must interact with gastrointestinal fluids so the active ingredient can be released and become available for absorption. The sequence from formulation breakdown to uptake influences how much drug enters circulation and how consistently therapeutic effects occur. Researchers therefore assess these stages when comparing dosage forms and evaluating pharmacokinetic behavior.
After absorption from the gastrointestinal tract, an orally administered drug may be metabolized in the liver before reaching systemic circulation. This first-pass process can reduce the amount of active ingredient available throughout the body and complicate interpretation of dose-response relationships. Pharmacology studies account for it when assessing bioavailability, therapeutic exposure, efficacy, and safety.
Food intake, gastrointestinal function, and interactions with other drugs can alter how an oral medication is absorbed or processed. These influences may change the amount of active ingredient reaching systemic circulation and can affect therapeutic outcomes. For this reason, researchers examine administration conditions and patient-related variables when interpreting pharmacokinetic data and safety findings.
A typical evaluation follows the medication from swallowing through dissolution, active-ingredient release, gastrointestinal absorption, and possible first-pass metabolism in the liver. Investigators then examine how much drug becomes available systemically and relate that exposure to therapeutic effects and safety. This workflow helps compare dosage forms and identify conditions that may influence performance.
Studies of oral medication can characterize dosage forms, bioavailability, pharmacokinetics, efficacy, and safety. Bioavailability indicates the drug's availability for systemic effects, while pharmacokinetics examines its movement through the body. Together, these measurements help researchers determine whether a formulation delivers the active ingredient consistently and whether its observed therapeutic effects occur within an acceptable safety profile.
Its noninvasive administration and convenience make oral medication valuable for treatment and for studies of local or systemic therapeutic effects. These practical features can support adherence, meaning consistent use of the prescribed medication. However, food, gastrointestinal conditions, and drug interactions may alter absorption, so convenience does not guarantee uniform exposure or identical therapeutic outcomes.
