math calculations with oral inhalers (1)

Calculate the total quantity and the total days supply for the following Rx: advair 250/50 1 inhalation bid #1 5 refills ------------------------------------------------------------ The doctor has prescribed advair diskus 250mcg/50mcg inhalation powder. It is supplied as an inhalation device containing 60 blisters, that is, 60 doses. The doctor says for the pharmacist to dispense one device. So, the total quantity to be dispensed is 60 doses. The sig says: use 1 inhalation by mouth twice daily The patient will use 2 inhalations per day. Then, the total days supply will be 60 divided by 2 which is 30 days. Notice that the doctor has given the patient 5 refills.

Calculate the total quantity and the total days supply for the following Rx: Combivent inh iii units ii puffs tid ------------------------------------------------------------ The doctor has prescribed Combivent Inhalation with 200 metered actuations and the content of the inhaler is 14.7g In other words, each inhaler has 14.7 g of medicine. The doctor wants the pharmacist to dispense 3 units, that is, 3 inhalers. We know that 1 inhaler = 14.7 g and, then, 3 inhalers = 44.1 g So, the total quantity to be dispensed is either 44.1g or 45g depending on the pharmacy computer system. The sig says: inhale 2 puffs by mouth three times daily In other words, the patient will inhale 6 puffs per day. We know that each inhaler has 200 actuations, that is, 200 puffs. But, the pharmacist will dispense 3 inhalers. Each inhaler has 200 puffs and, then, 3 inhalers have 600 puffs. So, the total days supply will be 600 puffs divided by 6 puffs which is 100 days. It is worth noting that most insurance companies may not want to pay for 3 inhalers all at once. The insurance company may force the patient to pick up one inhaler at a time. In this case, the total quantity prescribed would be either 44.1g or 45g, but the total quantity dispensed would be either 14.7g or 15g and the total days supply would be 200 puffs divided by 6 puffs which is 33 days.
