Polymast / Polymyxin B, Neomycin, Oxytetracycline, & Hydrocortisone Sterile Ointment: The Definitive Guide to Bovine Mastitis Therapeutics, Pharmacology, and Clinical Management

Managing acute and chronic mastitis, localized udder infections, teat injuries, and bacterial inflammatory flare-ups in lactating dairy cattle requires a broad-spectrum, multi-antimicrobial intramammary or topical formulation that provides rapid antibacterial action alongside potent anti-inflammatory relief. When high-yielding dairy cows experience bacterial invasion (such as Staphylococcus aureus, Streptococcus species, Escherichia coli, and other coliform pathogens) through the teat canal, prompt intervention is essential to halt intramammary tissue damage, prevent permanent quarter loss, restore milk quality, and protect overall herd profitability.

Left unmanaged, clinical mastitis leads to severe udder edema, systemic endotoxemia, permanent fibrosis of the mammary parenchyma, drastically elevated somatic cell counts ($\text{SCC}$), and severe economic losses from discarded milk and reduced lactation yield.

Relying solely on single-agent antibiotics or delayed intervention frequently fails to control mixed-bacterial infections or reduce acute inflammatory swelling within the delicate secretory tissues of the udder.

To provide comprehensive bactericidal coverage backed by established veterinary standards, practitioners rely on multi-active synergistic combinations. Polymast is a professional-grade veterinary formulation combining broad-spectrum antibiotics (Polymyxin B, Neomycin, and Oxytetracycline) with a targeted corticosteroid (Hydrocortisone) to deliver localized infection control and rapid anti-inflammatory relief engineered specifically for dairy cattle management.

Antimicrobial & Anti-Inflammatory Pharmacology

Polymast delivers a multi-faceted biochemical mechanism designed to eradicate Gram-positive and Gram-negative pathogens while simultaneously suppressing local inflammatory cascades:

1. Multi-Agent Mechanism of Action

• Polymyxin B Sulfate: Specifically targets and disrupts the cell membranes of Gram-negative bacteria (including Pseudomonas aeruginosa and Escherichia coli), neutralizing bacterial endotoxins within the udder.

• Neomycin Sulfate: An aminoglycoside antibiotic that binds to bacterial ribosomes, inhibiting protein synthesis and providing robust activity against various Gram-negative and Gram-positive organisms.

• Oxytetracycline Hydrochloride: A broad-spectrum tetracycline that halts bacterial growth by preventing polypeptide chain elongation, covering a wide array of secondary mastitis-causing pathogens.

• Hydrocortisone: A fast-acting glucocorticoid that rapidly reduces localized capillary permeability, edema, pain, heat, and swelling within the infected mammary quarter, protecting secretory tissue from permanent scar-tissue formation.

Primary Clinical Indications

Polymast is indicated across dairy cattle management for the targeted treatment of udder health challenges:

• Lactating Cow Mastitis: Treatment of clinical and subclinical bacterial mastitis caused by susceptible strains of Staphylococcus aureus, Streptococcus agalactiae, Streptococcus uberis, Escherichia coli, and associated pathogens in milking dairy cattle.

• Udder and Teat Inflammatory Care: Alleviation of acute swelling, congestion, and pain associated with localized bacterial infections or environmental udder trauma.

• Post-Milking Prophylactic Support: Supporting hygiene and infection control in high-risk quarters under veterinary direction.

Recommended Administration and Dosing Protocols

To guarantee absolute sterility, proper intramammary distribution, and compliance with milk safety standards, Polymast must be administered strictly according to approved route and hygienic guidelines.

Dosing Reference Table

The table below outlines standard operational parameters for Polymast administration in lactating dairy cattle:

Clinical Safety, Precautions, and Storage

• Milk and Meat Withdrawal Periods: Because antimicrobials and corticosteroids are infused directly into the mammary gland, strict adherence to mandatory pre-slaughter meat withdrawal and milk discard times is required. Milk taken from treated animals must be withheld from human consumption during treatment and for the specified withdrawal duration following the last administration.

• Aseptic Infusion Hygiene: To prevent introducing new environmental pathogens (such as Pseudomonas or yeasts) into the udder, always sanitize teat ends meticulously prior to application.

• Storage Parameters: Store in a cool, dry place protected from direct sunlight at controlled room temperatures between 15°C and 30°C (59°F to 86°F). Keep out of reach of children.

Frequently Asked Questions (FAQ)

What are the active ingredients in Polymast?

Polymast combines three broad-spectrum antibiotics (Polymyxin B, Neomycin, and Oxytetracycline) with the anti-inflammatory corticosteroid Hydrocortisone.

Can Polymast be used in milking dairy cows?

Yes, it is specifically formulated to treat mastitis and udder inflammation in lactating dairy cattle, though milk withholding times must be strictly observed.
