EUCASTin

EUCASTin is a fictional antimicrobial compound used in educational and methodological contexts to illustrate how the European Committee on Antimicrobial Susceptibility Testing (EUCAST) guidelines apply to antimicrobial susceptibility testing. It is not a real drug and has no clinical approval.

In this conceptual example, EUCASTin represents a broad-spectrum agent whose activity is assessed against representative bacterial isolates. No clinical data exist for EUCASTin, and it is not intended for therapeutic use.

Testing and interpretation: In simulations, minimum inhibitory concentration (MIC) values for EUCASTin are determined by standard methods such as broth microdilution or disk diffusion. Results are interpreted using EUCAST breakpoints, classified as susceptible (S), susceptible with increased exposure (I), or resistant (R).

Purpose and use: The EUCASTin example demonstrates how laboratory results translate into reporting and clinical decision making, including the consideration of achievable drug concentrations and dosing strategies. It also clarifies the distinction between real pharmacotherapies and teaching tools.

Notes: This entry emphasizes that EUCASTin is a fictional construct created for instructional purposes and should not be confused with real antimicrobial agents or clinical guidance. For real practice, EUCAST guidelines and approved drugs should be consulted.
