Introduction to Marbofloxacin (Zeniquin®)

Marbofloxacin is a synthetic fluoroquinolone antibiotic used in vet medicine. It’s known by the name 9-fluoro-2,3-dihydro-3-methyl-10-(4-methyl-1-piperazinyl)-7-oxo-7H-pyrido[3,2,1-ij][4,1,2] benzoxadiazine-6-carboxylic acid². Vets use it for dogs, cats, and other animals like rabbits, reptiles, and birds with special permission.

What is Marbofloxacin?

Marbofloxacin is a powerful antibiotic from the fluoroquinolone group. It works fast to kill bacteria, killing them in 20-30 minutes². You can give it to dogs orally or on the skin for infections in the skin, lungs, or mammary glands. The usual dose is 2.75 – 5.5 mg/kg once a day².

Marbofloxacin Brand Names

The brand names for marbofloxacin include Zeniquin®, Aristos®, Boflox®, Forcyl®, Kelacyl®, Marbocyl®, and Aurizon®³. You can buy it in tablets of 25 mg, 50 mg, 100 mg, and 200 mg³. For some infections, you might need to give it for up to 30 days. For urinary tract infections, it’s given for at least 10 days³.

“Marbofloxacin is a broad-spectrum antibacterial agent from the fluoroquinolone class of chemotherapeutic agents.”

How Marbofloxacin Works

Marbofloxacin is the key ingredient in Zeniquin®. It’s a fluoroquinolone that stops bacteria from making DNA during replication⁴. This makes it a strong choice for fighting many types of bacterial infections⁴.

Marbofloxacin works by blocking two important enzymes in bacteria: DNA gyrase and topoisomerase IV⁴. These enzymes help bacteria replicate and divide. By stopping these enzymes, marbofloxacin prevents bacteria from growing and dying⁴.

Marbofloxacin is especially good at fighting certain bacteria⁴. It’s been shown to work better than other antibiotics against bacteria from rabbits with respiratory infections⁴.

Marbofloxacin is easy for dogs and other animals to absorb and use well⁴. It spreads quickly in the body and gets to where it’s needed, making it a trusted treatment for many bacterial infections⁴.

“Marbofloxacin is a broad-spectrum bactericidal antibiotic with a high cure rate (about 70%) for naturally-occurring infected dogs when administered at a dosage regimen of 2 mg/kg body weight orally once daily for 28 days.”⁴

In short, marbofloxacin’s way of working, its antibacterial action, and how it moves through the body make it a top choice for fighting bacterial infections in dogs and other animals.

Marbofloxacin (Zeniquin®) for dog

Zeniquin® tablets with marbofloxacin are approved by the FDA for treating infections in dogs and cats⁵. They are used for skin infections, wounds, and urinary tract infections caused by certain bacteria⁵.

Zeniquin® is the main brand for marbofloxacin in the U.S. But, it’s also used in other animals like rabbits, reptiles, and birds⁶. Vets use it for conditions not listed in the FDA approval, if it’s right for the patient⁶.

Marbofloxacin in Zeniquin® works well against many bacterial infections in dogs and cats⁷. It’s absorbed well by dogs, with about 94% being used by the body⁷. In dogs, about 40% of the dose goes out in the urine. Cats excrete around 70%⁷.

“Marbofloxacin is a valuable tool in the veterinary arsenal, providing effective treatment options for various bacterial infections in our canine and feline patients.”

Marbofloxacin is usually safe, but vets must think about the right dose and side effects⁷⁵⁶.

Dosage and Administration

Vets need to think about several things when figuring out the right dosage and how to give Marbofloxacin (Zeniquin®) to dogs. They should give Marbofloxacin orally at a rate of 1.25 mg per lb of body weight every day. If needed, they can up the dose to 2.5 mg/lb⁸⁶.

Recommended Dosage

For treating skin and soft tissue infections in dogs, give Zeniquin tablets at 2.75 mg/kg once a day for 5 to 14 days⁸. You can increase the dose to 5.5 mg/kg for a few days after symptoms stop, up to 30 days, if the infection is severe⁸.

For urinary tract infections, use Zeniquin tablets at 2.75 mg/kg once a day for 10 to 14 days⁸. If the infection doesn’t get better in 5 days, check the diagnosis again⁸.

Duration of Treatment

For skin and soft tissue infections, give Zeniquin tablets for 2-3 days after symptoms stop, up to 30 days⁸⁶. For urinary tract infections, keep giving Zeniquin for at least 10 days⁸⁶.

Some things can change how much medicine a dog needs, like the type and severity of the infection, how likely the bacteria is to respond, and the dog’s own immune system strength⁷.

Pharmacokinetics of Marbofloxacin

Marbofloxacin, found in Zeniquin®, has great pharmacokinetic traits that make it effective⁹. It gets absorbed quickly and almost fully from the gut, with an AUC of 10.50 ± 2.00 μg·h/mL⁹. The highest level in blood was between 1.73 ± 0.35 μg/mL and 2.56 ± 0.71 μg/mL⁹. Its bioavailability of nearly 100% means most of the dose gets into the bloodstream¹⁰.

Absorption and Distribution

Marbofloxacin spreads widely in the body, reaching or beating the MIC for many bacteria within 2 hours⁹. Its broad distribution and deep tissue penetration help it fight a wide range of infections¹¹.

Metabolism and Excretion

Marbofloxacin leaves the body mainly through urine and stool¹¹. About 40% of an oral dose goes straight out in the urine, and the rest gets broken down by the liver¹¹. It takes around 8 hours to half-clear from the body at first, and 3.9 hours by the tenth day, showing quick removal⁹.

Studies on marbofloxacin have been done on many animals, like dogs, cats, and birds¹⁰. These studies help us understand how the drug works in different animals. This knowledge helps set the right doses for treating bacterial infections in pets and farm animals.

The table shows how Petsen and Marbocyl marbofloxacin work in beagle dogs¹⁰. It shows marbofloxacin’s high absorption and good pharmacokinetics in dogs.

In summary, marbofloxacin has great pharmacokinetic traits. It absorbs fast, spreads widely, and is cleared through urine and stool⁹¹¹. These traits make it effective against many bacterial infections in animals.

It’s important to watch the patient closely when using marbofloxacin⁸. Vets must think about the risks and benefits for each patient.

Potential Side Effects

Marbofloxacin can cause side effects, especially in the stomach, leading to vomiting, diarrhea, and less appetite¹³. Serious issues like joint problems, lack of appetite, and seizures are also possible¹. Cats might face blindness and eye issues with high doses¹³.

Marbofloxacin can make seizures worse in those prone to them, especially if they have liver or kidney problems¹³. It also makes skin more sensitive to the sun, so pets should avoid the sun too much¹.

Marbofloxacin comes in different sizes, but the usual dose for pets is 2.75 to 5.5 milligrams per kilogram of body weight daily¹⁷. Taking too much can harm the nervous system¹⁷.

Be careful with young pets when giving them marbofloxacin. Puppies and kittens need special care to avoid joint damage¹³. Cats and dogs under certain ages should be watched closely¹.

Don’t give marbofloxacin to pregnant or nursing pets, or those with seizure disorders or liver or kidney issues¹. Also, be aware of interactions with other medicines¹³¹⁷¹.

In conclusion, marbofloxacin is a useful antibiotic for dogs, but we must watch out for side effects to keep our pets safe¹³¹⁷¹.
