…but will it deliver?

I’m always on the lookout for neat new drugs to complement my arsenal of pharmaceuticals—and this one has the potential to change the way I practice medicine.

Marketed as Convenia in Europe, Pfizer’s new one-time injectable, two-week duration third-generation cephalosporin is an antibiotic approach that may also revolutionize how YOU deal with your pets’ healthcare needs.

Why?

Three reasons:

1-Because some pets are impossible to administer pills to. An injectable antibiotic lasting a full two weeks means I don’t have to convince my clients that pilling their fractious pets is a doable endeavor.

2-Because much as I may trust my clients, I know that busy lives mean sometimes the pills go by the wayside. And that means that I often feel responsible for the failure of my therapeutic regimens—despite knowing it’s possible my clients didn’t hold up their end of the bargain.

3-And finally, because a failure to administer antibiotic drugs in an appropriate manner means that bacterial resistance is a possibility. For reasons of public health and future antibiotic efficacy, this is a big deal. That’s why it makes me crazy to hear my clients say: “Oh that antibiotic—I have plenty left over from last time.” Grrrrrr…

It’s the Holy Grail of antibiotic therapy in animals: Create a drug indisputably efficacious over a prolonged period of time so that the vagaries of human administration and animal acceptance are minimized.

A few months ago, one of Dolittler’s UK readers extolled the virtues of this approach, then already available in Great Britain. She’d explained that the higher price for the two-week duration was way worth paying for when it came to her cat’s health. Presumably, her cat was one of the many kitties whose reluctance to accept oral treatments meant failure for almost every antibiotic approach.

At that time I was fascinated by the prospect of such a marvel. “GIMME!,” I remember commenting. This is something I absolutely need!

So when Pfizer’s reps recently made their way to my doorstep, promising me unprecedented access to this drug, I rejoiced. Our hospital has been selected as one of the local recipients of a sizable freebie sample—with one catch: I’m only to use the gifted antibiotic in my canine patients—for now, anyway.

Clearly, Pfizer sees great promise in the drug. But the company’s well aware that the smaller feline doses are unlikely to generate enough profit to justify their licensing expense. They need to push canine adoption of the drug if they’re to recoup their expenses in what they consider a reasonable timeframe.

But will my dog owners pay $100 a dose? Dunno. I do know my cat owners will gladly fork over $40, especially if their alternative is an angry kitty who’s willing to mount a clawed defense against offensive oral antibiotics.

So now it's your turn...will you pay up for Convenia's convenience?

Comments
Absolutely!!! I have one of those kitties myself and the inability to administer antibiotics has been a problem in the past. I would gladly pay extra to avoid the claws!

Provided it turns out to be safe, this is very exciting.

I have one kitty who is virtually impossible to medicate orally. After her dental, with extractions, my ability to get her rx'ed antibiotic into her was very unreliable. As she is now 8 years old and has transitioned into "geriatric" classification, I am full of dread for the day when she gets old age diseases requiring regular meds. I'm just not going to be able to pill this cat, or give her syringes full of liquid.

I am quite certain shots would be a much better option.

I know this is only an antibiotic but there are so many things that require antibiotics that I am sure this will come up again.

Aside: It never ceases to amaze me how many people whose cats are diagnosed with feline diabetes press their vets for alternatives to giving insulin shots. Often these people are given oral meds which are not effective in most cats and even when they work, I have been told that all they really do is force the failing pancreas to work even harder and can make things worse in the long haul.

But what really amazes me is that people prefer the struggle of pilling a cat to giving a shot in their scruff that they barely feel! If people realized how easy the shots are compared to the pills, I wonder if that would sway them?

My guys had it last year within days of its approval here in Canada and it seems to work very well. It sure beats liquids - yuk! - and while pills are pretty easy to administer, the 'conveniance' of a two-week injection is great.

I think we've used it about three times, fortunately not since 2007 - touching wood right now, everybody's been spectacularly healthy for a long time, even my old heart-failure suffering Wiener dog.
# Posted By Caveat | 5/8/08 10:20 AM
Having own cats that could do Exorcist style neck movements while claw-milling like a woodchipper--yesIi would go for that option.
# Posted By emily | 5/8/08 10:20 AM
Incidentally, regarding cost, it depends on the size of the dog. I have two Toys and my mini-dachshund, so it cost me around $18 a pop here which is actually cheaper than pills or liquids.
# Posted By Caveat | 5/8/08 10:22 AM
are you kidding I would sell my soul; not to have to pill another cat with antib's and if the manufactuere doenst think that cat owners will fork up big $$ for this they are mistaken
# Posted By james | 5/8/08 10:37 AM
not for the dogs - don't have problems medicating them, plus I'm not crazy about a drug that would stay in the system that long - what would happen if the dog didn't tolerate it very well?

for the cat - it would depend....
# Posted By lm | 5/8/08 11:48 AM
I would pay more than $40 for 2 weeks of antibiotics that I didn't have to somehow get down a cat's throat! I have one who is practically feral and who will not allow me to approach her after something like a vet visit. Pilling her is impossible unless I want to traumatize us both. What a god-send it would be to have one simple shot!
# Posted By Andrea | 5/8/08 2:52 PM
Reading this made me laugh as I have just been bitten in the thigh by my rescued rabbit (only had her 3 weeks, extremely scared of people) whilst attempting to administer Baytril-she had a reaction to her Myxi vaccination and then scratched it into a necrotic patch..

So a big YES PLEASE to long-acting medicines of any kind in the veterinary sphere. Although to raise the other side of the issue, after having seen a friend go through hell with the injectable contraceptive (lasts 6 months!), side-effects would be something to look at as a client. I would perhaps choose the shorter-acting drugs for the more people friendly of my pets.
# Posted By Sian | 5/8/08 4:09 PM
No, I would not use a new, long-acting drug on my dogs.

I've had some nasty drug reactions myself, and I don't like the idea of my animal suffering from a two-week period of distress that can't be stopped.

Drugs are tested, sure, but it's not until they are widely used that we know about a lot of side effects. I'm old enough and suspicious enough of marketing that it won't be my pets that suffer. Even though my vet was pushing them, I didn't do the long-term heartworm treatments, either, and I haven't lost a night of sleep about that one.

I have no trouble pilling my dogs, and like the idea that I can STOP the meds and call my vet if something goes terribly wrong.
# Posted By Sue | 5/8/08 5:26 PM
I was going to say yes, even without owning cats. However, everyone who brought up the potential for adverse reactions to long lasting medication has a great point. For the impossible to pill dog (yes they exist) it'd take a daily or every-other-day injectable antibiotic. She's much more cooperative about needles than she is about pills.
# Posted By AdoptedAPBTs | 5/8/08 5:57 PM
My experience with Convenia (my dachs had it twice for upper respiratory problems, my Griff once for an abscess and dental extraction) is that were zero side effects. No diarrhoea, no vomiting, no problems at all. There are also no food restrictions such as with Clavamox (no dairy of any kind for the course).

I'm not saying it's harmless, no drug is, but that was my experience and I'd let them take it again if it was the right drug for the problem.
# Posted By Caveat | 5/8/08 6:23 PM
It would save on tablets being spat out and not noticed until too late, but what I would really like is an antibiotic that did not lead to diarrhea, in other words didnt kill the good bacteria as well as the bad.
# Posted By Robin | 5/8/08 6:33 PM
I'm loving the name...
# Posted By anna | 5/8/08 10:18 PM
I'm not a big fan of "new "drugs. But even if it's not a new antibiotic and just a new dosing form, there are some important things I would need to know....like how it is suspended to make it long lasting....does it contain thimerisol?.....cats are much more sensitive long term to more things than people and dogs...
I hate pilling my cats...but a pill gun works wonders, and those I can't pill get injectible antilb's when needed. There are also pill pockets, they work well and now I see pill dough....then there is always a little cheese....

I'd have to wait quite a while and know quite a bit more before I was willing to use this.
# Posted By LorriM | 5/8/08 11:22 PM
Add me to those who would prefer injection to pills for my cats. Although I can give them pills, they don't like it any; but they barely even flinch at injections. Even daily injections would be better than daily pills. And I think the concern for side effects is no worse than with any drug: although the immediate gut feeling is to think "lasts two weeks? must be really strong", that probably isn't true; short- or long-acting drugs both have a variety of ways they could go wrong.
# Posted By T.T. | 5/8/08 11:26 PM
Is there anything like that for fleas?? **Just wondering.
# Posted By ashleigh | 5/8/08 11:27 PM
Personally, I prefer to have pills encased in yummy treats like peanut butter. Much better than getting a shot.

Sincerely,
Aoife the flat-coated retriever
# Posted By flattie | 5/9/08 12:13 AM
I'm with Im and Sue (and others?) -- I can't justify the expense for my dog, who is easy to pill. And I've become an ace record keeper, even for two weeks at a time.

I hasn't even thought of the potential of a drug reaction which might last for two weeks. Is there a way to check beforehand -- something like "test in an inconspicuous spot before using"?
# Posted By M | 5/9/08 1:56 AM
One thing I like about the product is its extensive use in Europe and Canada where minimal reactions have been noted. Plus, third generation cephalosporins like this one tend to have fewer GI effects. So, for example, if your pet can take Simplicef just fine, this should be no different--theoretically. But I'm with you on preferring to pill my dogs if I'm sure I can get it into them on a timely basis. Cats? It's hit or miss depending on the personality type I'm dealing with. And a few dogs are equally difficult (small, picky eaters, especially. I think I'll be using a lot of this.
# Posted By Dr. Patty Khuly | 5/9/08 8:33 AM
Ashleigh: For fleas, I've been using Comfortis if Frontline and Advantage don't seem to be doing the trick. It's a once a month pill but it's only for dogs. Injectable flea meds have not yet been developed--I imagine the market to be quite small.
# Posted By Dr. Patty Khuly | 5/9/08 8:35 AM
Is the dosage determined by weight? Or is it yet another One-Dose-Fits-All med? I would not pay $100 for long lasting antibiotics for my dog (she's only 8 pounds).All it takes for her to gulp down a pill is a little peanut butter or cream cheese. No sweat.

It's interesting how disconnected Pfizer is from their target market. It seems, from these comments alone, that cat people would benefit greatly from this and would be willing to pay the higher cost.
# Posted By Creature of Habit | 5/9/08 8:47 AM
Creature: Pfizer will definitely make this available for cats--I just think they want to get the excitement going in the dog market, too (hence the freebie). And yes, it varies by weight. I think someone earlier said their small dogs' dose cost $18.
# Posted By Dr. Patty Khuly | 5/9/08 9:35 AM
Ashleigh: Injectable fleatreatment does exists (at least in Europe). The active drug is called lufenuron, it stops the fleas development from eggs to larvae and from larvae to full-grown fleas. It does not kill adult fleas, so it can only be used as a preventive treatment. One injection lasts 5-6 months. We have a few clients, who perfer this kind of fleatreament, but mostly people are happy with the spoton, so they safe their cat the trip to the vet.

Pills are no problem for my dog. I could give her a pill the size of a golfball if I wrapped it in a piece of cheese first.

If there is any evidence that it works better to knock down my dogs periodic ear infections hen I would certainly spring for it.
# Posted By Larry | 5/9/08 3:15 PM
Here are my questions: Would this particular antibiotic be chosen if it were not injectible? IOW is it the appropriate drug for the situation or does it being injectible override all other considerations? What is known about bacterial resistance to this product right now? Does Europe or Canada have a reporting mechanism for adverse reactions like the US does and is it public like the Adverse REaction synopses available to us? Or will we be seeing reports of heretofore "unknown" reactions within a year or so. And Dr. Patty, do the drug reps give you full research articles to go with the freebies?

Oh, and I wouldn't touch lufenuron (injectible Program) with a barge pole. Cats do not need more shots. There have been some problems with long persisting lumps with this product. CLEANING is the primary reaction to a flea infestation, followed by something like Precor and a topical.
# Posted By CathyA | 5/10/08 9:26 AM
Oh yeah, that's right. We have it here, too. It's called Program. I haven't used it in about ten years. Sorry for the short memory.
# Posted By Dr. Patty Khuly | 5/13/08 11:30 AM
Oops: In the comment above I was addressing the injectable flea medication issue.

CathyA: I think antibiotic selection in pets is often related to its convenience and our clients' compliance. If we make it convenient, you'll be more compliant. Hence, we should see less resistance.

Is it the right antibiotic? Well...depends. It's best for wounds and skin infections. It wouldn't be my choice for respiratory, gastrointestinal or urinary issues, for example. Vets do actually make antibiotic decisions based on more than just convenience, of course, but it's a big issue for us.
# Posted By Dr. Patty Khuly | 5/13/08 11:36 AM
I wonder if you feel that Vets are not giving pets far too many needless antibiotics since here the Veterinary Times have published an article saying that Vets are over-prescribiing antibiotiics and I found that I hardly ever left the Vet without being given a packet of antibiotics and feel Vets give them for just about everything even illnesses they know will not be cured by antibiotics such as struvite crystals which are caused by feeding dry pet food and a lack of protein in pet food and lack of water taken in by cats fed dry food but instead of realising this was the cause of my cat's illness the Vet gave me endless antibiotics and kept catheterising my cat and operated on him. He admitted that infection is not usually anything to do with struvite crystals but here a BBC report says Vets are giving needless drugs just to make money. I am concerned that Vets use an arsenal of pharmaceutical drugs on pets instead of telling clients to boost the immune system of the pet by taking it off all pet food and feeding it the food Mother Nature intended it to be fed since giving steroids etc. only mask the illness so sorry Dr. Khully I can't get excited about Pfizer. The Wellcome Trust have given 13 M Pounds Sterling between all the British veterinary schools but to me this is just like the pet food companies giving funding to the veterinary schools since it means Vets give out drugs and think there is a pill for every illness when they should be boosting the immune system of animals by getting them off all pet food and helping the immune system fight any illness or infection.

My cat just started this 2 days ago. I have not noticed any side effects. Before the shot, I thought he was going to die and now I think we may have some hope. We did blood work and test and nothing shows up. Thinking he got bit by infected mosquito!!!! Not sure if he has West Nile but praying its just an infection. I will write back after he has been on this longer. 2 days can't tell yet but hes hanging in there!
