A slow-drip capsule stretches medicine through the day
The idea behind the cue
Extended-release formulations are designed to release drug over an extended period, often reducing dosing frequency and smoothing peaks and troughs. They should generally not be crushed, split, or chewed because that can defeat the release design.

A slow-drip capsule stretches medicine through the day
Acronym
ES — Eccentric Sloths.
Story
A capsule pours beads from a tiny hourglass while the patient goes about the day. The medicine is built to release gradually instead of all at once.
Connect the pieces
- E (Eccentric) → Extended-release: Release drug over an extended period, often lowering dosing frequency and smoothing peaks and troughs.
- S (Sloths) → Sustained-release: A slow-release pattern over time; crushing or chewing can defeat the designed release behavior.

Know the limits
Not every product labeled ER uses the same technology or has identical handling instructions.
