Volume measurement conversion.

[Cranfield]

Being a total Luddite I am rather confused over some cat medicine I have to administer (to the cat).

 

It is an aerosol type container and is a paste like substance.

The dose is "1 to 2 ml twice a day".

Each "pump" releases 1 ml.

 

My question is, the container holds 250mg, so at 4 ml a day, how many days will it last ?

[Chard]

Seems to be a converter thingey here

 

But I'm getting confused fiddling with it

 

I don't see how it would work actually, as different liquids/substances would have different strengths/weights etc.

 

The plot thickens

I may be wrong Cranfield but the 250mg may relate to the active ingredients in the paste rather than the actual volume,

 

Is it a long term medecine or just one for a course of treatment?

tough one, it really depends on the weight and volume of the paste. as daft as it sounds, weighing one mil of the paste would possibly be your best bet to work out an accurate result

actually I'm right as 1 milligram = 0.001 grams so can't relate to the size of your container just the amount of active ingredient in it

[Cranfield]

Thanks for the replies and having checked the translation (its written in French), it seems that it is the contents of each ml that contains 250 mg of an active ingredient, not the container.

 

My wife (who speaks French) is now searching the container with a magnifying glass, to see if the contents are mentioned anywhere in the small print.

How big is the container? I assume it is a cylinder, so height and diameter.

We can assume it density (SG) to be close to that of water and therfore 1000 kg/m3. And from that we can get very close to number of how many days it will last @ 2ml per day.

actually landy, when it comes to aerosols the 1 g/ml water assumption breaks down. That is because the propellants are so much lighter that the actual density of the dispensed product will be lower than 1 in many cases. And, in this case it is a paste so without knowing what the paste is made from the density could be all over the map.

 

Better bet is to put the rough can dimensions up, calculate the capacity, and compare against the chart here:

 

http://www.bama.co.uk/prescribed_quantities/

 

That will get you in the ballpark. Also look for this symbol on the can. That tells you it complies with the aerosols directive and the fill levels will be pretty close to what the FEA recommends and what BAMA outlines on their page above.

 

 

 

Realistically, is the can the size of an aerosol room air freshener? I suspect not and they are in the 300ml range. That would be 75 days at 4 ml /day. More realistically it is the size of a travel aerosol hair spray which is 100ml (thus 25 days or so). There are aerosols that are smaller as well. If you're talking about a 3" 12 ga magnum cartridge then you're in the 50 ml territory or abotu 2 weeks.

 

Thanks

I think Cranfield need to confirm, but from reading it my view is that it was not a gas / aerosol, but simpley a press to pump type unit dispensing a paste. Like a hand wash dispenser.

 

So ineffect there is no proplant other than the mechnaical action of the pump unit.

I think working this out is going to be the easy bit - Now try giving it to the cat !!

Yes!!! Reminds me of

 

 

Washing the toilet bowl

=======================

 

1. Put both lids of the toilet up and add 1/8 cup of pet shampoo to the

water in the bowl.

 

 

2. Pick up the cat and soothe him while you carry him towards the

bathroom.

 

 

3. In one smooth movement, put the cat in the toilet and close the lid.

You may need to stand on the lid.

 

 

4. The cat will self agitate and make ample suds. Never mind the noises

that come from the toilet, the cat is actually enjoying this.

 

 

5. Flush the toilet three or four times. This provides a 'power-wash'

and rinse'.

 

 

6. Have someone open the front door of your home. Be sure that there are

no people between the bathroom and the front door.

 

 

7. Stand behind the toilet as far as you can, and quickly lift the lid.

 

 

8. The cat will rocket out of the toilet, streak through the bathroom,

and run outside where he will dry himself off.

 

9. Both the toilet and the cat will be sparkling clean.

 

Yours Sincerely,

 

The Dog

It is a press to pump type container, it just looks like an aerosol.

My wife has calculated (don't ask) that there is 100ml in the container, she is a wondrous being and very lucky to be married to me.

Incidentally, the cat loves it and actually licked the residue off my finger (which is what it said in the advert).

25mg = 2500ml

2500 devide by 4 =6.25

anser 6.25 days

I will bet on 25 days @ 2 pumps twice per day i.e 4ml per day, with 100ml in the container.

What is the products name? If it is a drug it should state a dose rate.

 

eg if it was amoxycillin the dose rate would be 10mg/kg. Assume the cat weighs 5kg. Cat requires 5*10 = 50mg/day.

 

If the container contains 250mg and the appropriate dose is 4ml then we have 5 days supply (250mg/50mg/day) so 4ml*5 days means the bottle contained 20ml!

no theres 25mg in the bottle whitch there is 1000ml to the mg so thats 2500ml devide that by the amount that has to be administed each day whitch is 4 ml

comes to 6.25 so thats 6 and 1/4 days worth

apache we would have the same anser

 

cranfield let us know how long it lasts for lol

[malkiserow]

My guess is that the weight should be for the contents not the whole package.

 

Assuming 1 pump per dose twice a day that would be about 110 days worth allowing for the pump pipe being a bit shy of the base.

 

Therefore 2 pumps per dose means about 55 days

forget the mg people and work on the dose

 

If you're giving 1ml per day then you've 100 days supply, if its 2 ml its 50 days supply really not that complicated

So my answer of 25 days at 4ml per day is the same as 2ml per day = 50 days.

 

Come on Cranfield put us out of our missery!

[night owl]

stupid topic lol forgot i had the toast under the grill intill the fire alrm went of any one for black toast lol

[Cranfield]

As I said in post 12, its 100ml at 4 ml a day it will last 25 days.................I think.

[night owl]

now im confused lol in post 1 you said 250mg . never mind its friday shooting tommor

[casts_by_fly]

the 250 was the active drug in a dose. 250 mg per pump (1 ml). Cranfield made a mistake in his first post but corrected it later.

 

Thanks,

Rick

Best way to administer a pump action cure all to a cat is to get your good lady to throw it in the air whilst simultaneously shouting "PULL"

 

Only Joking of Course.
