Solution

To prepare the prescription, you need to calculate the amount of Losartan and Lactose needed for each capsule and then multiply by the total number of capsules.

  1. Determine the amount of Losartan per capsule:

The prescription calls for 15 mg of Losartan per capsule. Since the tablets are 50 mg each, you would need to use 0.3 (15 mg / 50 mg) of a tablet for each capsule.

  1. Determine the amount of Lactose per capsule:

The prescription calls for the total weight of each capsule to be 150 mg. Since you already have 15 mg of Losartan, you would need to add 135 mg (150 mg - 15 mg) of Lactose to each capsule.

  1. Calculate the total amount for 30 capsules:

For Losartan, you would need 9 tablets (0.3 tablet/capsule * 30 capsules).

For Lactose, you would need 4050 mg (135 mg/capsule * 30 capsules).

So, to prepare 30 capsules, you would need 9 Losartan tablets and 4050 mg of Lactose.
