Re: How many tablets will it take to fill the order? I have been trying to solve and can't get answer, help me.......!..

[Guest guest]

What is ordered is 125 mg bid x 7da

What you have is 0.5 gm, so you would convert 0.5 grams to mg

which is 500 mg

so now since your measurements are the same, math can be done.

how much is needed:

125mg x 2(bid) x7da= 1,750mg

how much of what you have on hand that will make up what is ordered:

by dividing-

1,750mg/500mg= 3.5 tabs

I double checked my work, so i hope this helps you.

Dear battin,

I do apologize that it has taken me a while to get back to you. I have had

problems with the site for the last 7 days with the remodeling. It appears for

now that has reverted back to its old format, which I am happy about. But

I am sure they will try it again in a beta stage.

Well I tried to reply several times and actually thought I had, but every time I

pushed the 'send/post' button it shut down my site. So it was not until Sat

night that I realized that my posts were not all up.

Well let me get to your question now:

Notice that 125mg is 1/4 of 500mg. One problem is that the drug must be scored

to get a one -half ro one-quarter tablet for a dose.

Scored means it has a grove or line that you use to cut the tablet. It implies

that there is no special coating on the tablet that if broken or cut would mean

the inside is exposed to the person's stomach or mouth or intestines to burn or

cause an ulcer OR that it would not cause an overdose in the case of a timed

release drug.

To solve IF the tablet was scored:

Convert 0.5 gm to 500 mg using dimensional analysis: 0.5 gm x 1000mg/1 gm = 500

mg

Ratio/Proportion would work well also.

Using R/P find how many tablets you will need per dose IF they were scored:

Flagyl 125 mg bid x 7 days

500mg-----125 mg

------- = -------

1 tab -----X tab

1 x 125

-------- = X tab = 0.25 tablet (1/4 tablet)

500 mg

So the question remains is the tablet scored?

I am going to ask you to do the research!

Now how many tabs would we need if the tablet is scored?

0.25 tablet/dose x 2 doses/day x 7 days/Rx

Answer = 3.5 tablets IF Scored

It could be answered by ratio/proportion all at once

Flagyl 125 mg bid x 7 days

First find out the total number of mg you need for the whole 'duration' or Rx:

125 mg/dose x 2 doses /day x 7 days / Rx = 1750 mg/Rx

Then use R/P:

500mg-----1750 mg

------- = -------

1 tab -----X tab

1 x 1750

-------- = X tab = 3.5 tablets (notice you will need scored tablets)

500 mg

Again I will ask YOU to do some research to find out what this drug looks like:

scored or not. Then get back to me/US and let us know give us the link etc.

Others at home doing this problem should also do the research. WHY? Well in a

REAL classroom you would LEARN and DO such researches because on the job you

would have to.

Try to find pictures of this drug or a description of it.

Hope this helps you out,

Dear meyaiwee,

I tried to answer you about an hour ago, but I accidentally pressed somethng

near my space bar and it dissappeared.

You may have the makings of a pharm tech teacher as soon as you get more

experience. While your explanation matematically is good, you need to know more

about the dosage form of the drug and its availability. Only experience or

research will tell you this.

ANY time you end up with a fraction of a tablet you must be certain if breaking

or cutting that tablet is pharmacologically advisable, sound and would not harm

the patient.

Please refer to my previous post and my answer regarding this. Then go to the

net or books and research this drug, dosage form and availability.

IF you find that it can not be cut or it is not scored, try to find out the

reason why. Is there an alternative to this prescription. What should be done?

by the tech? by the RPh?

Thank you for your feedback.

I'm fairly new to this group, so while i was going through posts I came across

this question that I knew how to answer. What I didn't know is that it had

already been answered, although I'm glad I did because you pointed out something

I need to keep in mind.

I'll be sure to look into the common drugs and their dosage forms and apply them

to memory for future reference.
