Dextroamphetamine amphetamine er?

Short answer:

- Dextroamphetamine: the D-enantiomer of amphetamine. It’s a stimulant used for ADHD and narcolepsy. It’s available in immediate-release (IR) and extended-release (ER) forms.

- Amphetamine (ER): usually means an extended-release product that contains a racemic mixture (both dextro- and levo- enantiomers) or mixed amphetamine salts. Examples: Adderall XR (mixed salts, extended-release), Mydayis (extended-release, long-acting).

Key points:

- ER = extended-release, designed to release the drug over a longer period (often 8–16 hours depending on the product).

- Dextroamphetamine ER examples include Dexedrine Spansule (dextroamphetamine sulfate, ER).

- Dosing is once daily in many cases; swallow capsules whole unless the label says otherwise. Do not adjust without a clinician’s guidance.

If you’re asking about a specific product or need guidance on choosing between them, tell me the brand/name or your goal (ADHD, narcolepsy, duration needed), and I can tailor the info. And always consult a clinician for medical advice.
