Buy Excede (Ceftiofur Crystalline Free Acid) Sterile Suspension Online
Managing acute bacterial respiratory infections in horses and livestock requires rapid, sustained antimicrobial coverage to prevent permanent lung damage and systemic stress. In equine medicine, lower respiratory tract infections caused by Streptococcus zooepidemicus can lead to severe coughing, nasal discharge, high fever, and prolonged lay-off times. Similarly, Bovine Respiratory Disease (BRD) complex in beef and dairy cattle can spread rapidly through pens, causing lung consolidation and significant economic losses.
Conventional daily antibiotic protocols require repeated captures, restraining stress, and multiple needle sticks. This frequent handling increases anxiety in sick animals, elevates labor costs, and increases the risk of injection-site trauma.
To achieve sustained therapeutic blood levels while minimizing animal stress, veterinary practitioners rely on sustained-release beta-lactam antimicrobials. Excede Sterile Suspension (manufactured by Zoetis) is a premier, broad-spectrum third-generation cephalosporin antibiotic. Powered by Ceftiofur Crystalline Free Acid (CCFA) at a concentration of , Excede utilizes a patented oily suspension base that slowly releases active ceftiofur into circulation. This unique formulation maintains therapeutic plasma concentrations for up to 7 to 10 days from a minimal injection schedule.
This comprehensive clinical manual covers the sustained-release pharmacology, species-specific injection routes, target pathogen indications, and precise administration protocols for Excede.

Beta-Lactam Mechanism of Action
Ceftiofur is a broad-spectrum, third-generation cephalosporin that acts bactericidally against Gram-positive and Gram-negative pathogens. It operates by inhibiting bacterial cell wall synthesis. Ceftiofur binds to essential penicillin-binding proteins (PBPs) involved in cross-linking the peptidoglycan cell wall layer, leading to osmotic instability, cell wall rupture, and rapid bacterial death.
Extended-Release Crystalline Depot
Unlike conventional ceftiofur sodium or ceftiofur hydrochloride salts that absorb and clear rapidly, Ceftiofur Crystalline Free Acid (CCFA) is formulated in a specialized sustained-release oil base:
-
Slow Dissolution: Following subcutaneous or intramuscular injection, the crystalline matrix forms a localized depot that slowly releases active ceftiofur into the capillaries over several days.
-
Metabolic Conversion: In the body, ceftiofur is rapidly metabolized to its primary active metabolite, desfuroylceftiofur, which retains equivalent antimicrobial activity and binds to plasma proteins to maintain extended tissue protection.
Target Pathogen Spectrum
-
Equine Pathogens: Primary activity against Streptococcus equi subsp. zooepidemicus, a leading cause of equine lower respiratory tract infections.
-
Bovine Pathogens: Broad activity against Mannheimia haemolytica, Pasteurella multocida, Histophilus somni, and anaerobic foot rot pathogens including Fusobacterium necrophorum and Porphyromonas levii.
Core Multi-Species Clinical Indications
Excede 200mg/ml is a foundational therapeutic tool across equine performance stables and commercial livestock operations:
-
Equine Lower Respiratory Tract Infections: Treats acute respiratory infections caused by susceptible strains of Streptococcus zooepidemicus in horses.
-
Bovine Respiratory Disease (BRD) Treatment & Metaphylaxis: Controls and treats BRD associated with M. haemolytica, P. multocida, and H. somni in beef, non-lactating dairy, and lactating dairy cattle.
-
Bovine Foot Rot (Interdigital Necrobacillosis): Provides rapid, sustained treatment for acute foot rot infections in cattle.
Recommended Administration and Dosing Protocols
Because Excede utilizes an extended-release crystalline formulation, administration routes and anatomical injection sites differ significantly between cattle and horses. Strictly follow these species-specific protocols.
Species Dosing and Administration Reference Table
The table below outlines standard clinical dosing parameters for Excede 200mg/ml:
Clinical Safety, Regulatory Compliance, and Storage
-
Strict Anatomical Route Compliance:
-
In cattle, Excede must be injected at the base of the ear. Do not inject subcutaneously in the neck or body, as this alters depletion kinetics and can result in violative tissue residues.
-
In horses, Excede must be administered intramuscularly. Do not inject subcutaneously in horses.
-
-
Intra-Arterial Injection Warning (Cattle Ear Site): When administering at the base of the ear in cattle, avoid injecting into the carotid arteries at the base of the skull, as accidental intra-arterial entry can cause sudden central nervous system collapse or death.
-
Milk Safety in Dairy Cattle: Excede carries a 0-hour milk discard period when administered strictly according to label directions at the base of the ear in lactating dairy cows.
-
Slaughter Withdrawal Period (Cattle): Must not be slaughtered for human consumption within 13 days of the last treatment.
-
Storage Parameters: Store at controlled room temperature between 20°C and 25°C (68°F to 77°F). Protect from freezing. Shake well before use to resuspend the crystalline oil base. Use within 12 weeks of first puncture.
Frequently Asked Questions (FAQ)
Why is Excede injected at the base of the ear in cattle?
Injecting at the base of the ear allows the oil-based crystalline suspension to form a sustained-release depot that depletes predictably without leaving violative drug residues in edible muscle tissues, allowing for a 0-hour milk discard period in dairy cows.
How many doses of Excede do horses require for a complete treatment cycle?
Horses require a 2-dose treatment regimen. The second intramuscular injection must be administered exactly 4 days (96 hours) after the first dose to maintain therapeutic blood levels against Streptococcus zooepidemicus.
Does Excede require refrigeration?
No. Excede should be stored at controlled room temperature between 20°C and 25°C. Do not freeze. If the product settles during storage, shake the vial vigorously before drawing up the dose to ensure an even suspension.
