hydrobromide
Very LowSpecialized/Technical
Definition
Meaning
A crystalline chemical compound formed by the combination of hydrobromic acid with an organic base, particularly used in medicinal chemistry to improve stability or solubility.
The salt form of an alkaloid or amine drug, where the molecule is bound to a hydrobromic acid (HBr) molecule. This formulation often provides better stability and shelf life for pharmaceutical products.
Linguistics
Semantic Notes
This term is almost exclusively used in pharmaceutical, chemical, and medical contexts. It does not have a metaphorical or layperson's meaning. It is typically part of a full drug name (e.g., scopolamine hydrobromide).
Dialectal Variation
British vs American Usage
Differences
No significant differences in usage, spelling, or meaning. Both varieties use the same term with identical application in technical fields.
Connotations
None beyond its strict pharmaceutical/chemical meaning.
Frequency
Equal, very low frequency in both varieties, confined to highly specialized texts.

Context Usage
Business
Rare, only in pharmaceutical manufacturing or procurement contexts.
Academic
Used in pharmacology, medicinal chemistry, and pharmaceutical science research papers.

Virtually never used. A patient might see it on a medication label.
Technical
Primary context. Precise term for a specific drug salt formulation in chemistry and medicine.
Examples
By Part of Speech
verb
British English
- The amine was hydrobromided to form a stable salt.
American English
- The compound was hydrobrominated to yield the hydrobromide salt.
adjective
British English
- The hydrobromide formulation is preferred for this injection.
American English
- The hydrobromide salt version has better solubility.
Examples
By CEFR Level
- This medicine label says 'hydrobromide'.
- The doctor explained that the 'hydrobromide' part of the drug name is just a salt.
- Scopolamine hydrobromide is commonly used to treat motion sickness and nausea.
- The pharmacological efficacy of dextromethorphan is unchanged in its hydrobromide salt form, but its crystallinity and handling properties are significantly improved.
Learning
Memory Aids
Mnemonic
Imagine a HYDROgen BROMIDE molecule latching onto a medicine (like 'hydro' from water and 'bromide' from the element bromine) to make a stable salt.
Conceptual Metaphor
A chemical 'carrier' or 'stabilizing jacket' for an active drug molecule.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with generic 'bromide' (бромид). 'Hydrobromide' is a specific salt. Do not translate it as 'гидробромид' without verifying the standard pharmaceutical term in Russian, which is often 'гидробромид' but sometimes part of a standardized drug name.
Common Mistakes
- Misspelling as 'hydrobromine' or 'hydrobromid'. Incorrectly using it as a standalone term for a drug instead of as a salt suffix (e.g., saying 'I took a hydrobromide').

FAQ
Frequently Asked Questions
No. It is the salt form of a drug. The active part is the base molecule (e.g., scopolamine). 'Hydrobromide' refers to the hydrobromic acid salt attached to it.
Yes. They are different salt forms using different acids (hydrobromic acid vs. hydrochloric acid). This can affect the drug's properties like solubility, stability, and melting point.
Generally, no. It is important for pharmacists, chemists, and doctors. Patients only need to recognize it as part of a medication's full name.
Almost never in correct usage. It is almost always preceded by the name of the alkaloid or amine (e.g., 'atropine hydrobromide').
