Norodine contains two ingredients which act synergistically to block important metabolic pathways in bacteria. This results in efficacy against a wide range of different bacteria and so Norodine can be used for many types of infection. It is used for infections affecting the respiratory and alimentary systems, as well as many other types of soft tissue infection, including infected wounds and septicaemia. The different formulations of Norodine are intended for use in dogs, cats, horses and calves.

Pharmacological particulars

Pharmacotherapeutic group: Antibacterials for systemic use.

ATC Vet Code: QJ01EW10

Pharmacodynamic properties

Sulphadiazine (SDZ) inhibits the incorporation of para-aminobenzoic acid into folic acid and trimethoprim (TMP) inhibits the enzyme dihydrofolate reductase (DHFR) which converts dihydrofolic acid into tetrahydrofolic acid. TMP and SDZ act together synergistically with a double-blockage mode of action. The combination is bactericidal inhibiting sequential steps in the synthesis of purines which are required for DNA synthesis. TMP-SDZ combinations have a broad bactericidal action against many gram-positive and gram-negative aerobic bacteria, and a large proportion of anaerobic bacteria.

of tabletswhat is the doseage for a 40kg dog per day

  • Veterinary Advisor

The dose specified by Norbrook for a 40kg dog would be 2.5 tablets daily. However Norodine is often given twice daily so it would be best to consult your vet for the dose they recommend.

Routine prescriptions

Rebecca Lea

  • VioVet customer since 2015
  • From: Wiltshire, United Kingdom

I run a sales prep yard and need routine antibiotics/bute/gastroguard etc etc for a number of horses, up to 12.
Can I get my vet to write a general prescription covering all these drugs or do I need to lodge a specific prescription every time I need to order?

  • Non-Executive Director

Basically we can supply pretty much whatever your vet allows on the prescription. If you ordered vast amounts which were clearly above what a yard of your size could use, we would have to question it. However as long as your purchases seem reasonable for what you are doing, we will supply whatever we can. That means it is down to your vet to prescribe whatever he/she thinks is reasonable in the circumstances. If your vet is happy to provide a prescription which allows for all the medication you require, then you can send it to us and just draw amounts of medication off that one prescription as you need them. You might need a new prescription every 6 months or a year, but it could cover whatever you need. However this is entirely down to your own vet and he/she is given great freedom within the law to prescribe whatever is reasonable in the circumstances. Vets are given guidelines from the RCVS and different vets interpret these in slightly different ways, but essentially it is up to your own vet.
