To create a 1:15 ointment, you would need 1 part active drug and 15 parts ointment base. Since you have 95 grams of active drug, you would need (95 grams / 1 part) * 15 parts = 1425 grams of ointment base. Therefore, you would need a total of 1425 grams of ointment base to create a 1:15 ointment with 95 grams of active drug.
