Bimeda US launches Macrosyn™ (tulathromycin injection) 100mg, becoming the first available and launched FDA-approved brand alternative Draxxin® in the US.


Bimeda is pleased to announce the launch of Macrosyn (tulathromycin injection) 100mg. Macrosyn is a ready-to-use injectable solution containing 100 mg of tulathromycin/mL, a broad spectrum, fast-acting antibiotic for use in cattle and swine. Macrosyn is available in 100mL, 250mL, and 500mL sizes.

In gaining approval from the U.S. Food and Drug Administration (FDA), Macrosyn was granted the same label claims as Draxxin and is bioequivalent to the pioneer product in:

• Active ingredient & inactive ingredients (including carriers and excipients)
• Strength, dosage form & route of administration

Additionally, Macrosyn meets the same quality and safety requirements and is manufactured at an approved FDA facility.

Gavin Tierney, CEO, Bimeda, shared his excitement, commenting that:

“Macrosyn is a great addition to Bimeda’s extensive range of products. Our longterm experience in the brand alternative business is proving successful by being the
first to the US market with a brand alternative tulathromycin. We are also proud to
license and manufacture Macrosyn in our new state-of-the-art production line in
North America.”
