Tolaz MD 10 (olanzapine)	10 tablets, 10 mg each	29
Oleanz 10 (olanzapine)	10 tablets, 10 mg each	86
Olan 10 (olanzapine)	10 tablets, 10 mg each	65

Total dose = 100 tablets = 100 × 10 = 1000 mg. Total cost = 582 Indian rupees for 100 tablets. Total dose = (number of tablets in one strip/package multiplied by dose of each tablet) × number of strips/packages. Per mg cost = total cost (Indian rupees)/total dose (mg) = 582/1000 = 0.58 Indian rupees per mg.
