Based on the information provided, the current inventory count for Enablex for overactive bladder is 405 tablets. The par level, which is the desired or minimum level of inventory to be maintained, is 100 tablets.
To determine the reorder quantity, you can calculate the difference between the current inventory and the par level:
Reorder Quantity = Par Level - Current Inventory
Reorder Quantity = 100 tablets - 405 tablets = -305 tablets
In this case, you have an excess of 305 tablets over the par level. Since you want to maintain a par level of 100 tablets, you do not need to reorder any Enablex tablets at this time. Your inventory is sufficient.
