We are facing the issue in getting attribute value

Hai

We have created the Dropdown attribute in programatically .Unfortunately We made the mistake in source file ,for value we given the static value entries.

                      ['label'=>'Tablets', 'value'=>'1'],
                      ['label'=>'Wafers', 'value'=>'2'],
                      ['label'=>'Wet', 'value'=>'3'],
                      ['label'=>'Whole Bean', 'value'=>'4'],
                      ['label'=>'Wipess', 'value'=>'5']

Now we are facing the issue in getting attribute value.If we are trying to change the value manually.I will not reflect in admin product creation and updation?

Can you please suggest the solution?
