The usual starting dose of sodium oxybate is 4.5 g per night in two equally divided doses, taken 2.4 to 4 hours apart. a sodium oxybate oral solution is available in 180-ml bottles, containing sodium oxybate, 50% w/v. how many divided doses are available in each container?

40

Step-by-step explanation:

The starting dose of Sodium Oxybate is 4.5 gm per night in two equally divided doses.

So, each divided doses of Sodium Oxybate will contain 4.5/2 =2.25 gm.

Now, a Sodium Oxybate oral solution is available in a 180 ml bottle that contains 50% w/v of Sodium Oxybate.

Hence, 50 gm of Sodium Oxybate will be there in 100 ml of the solution.

So, 50×180/100 =90 gm of Sodium Oxybate will be there in 180 ml of the solution.

Therefore, in each container of the oral solution, there will be 90/2.25 =40 divided doses are available. (Answer)
