Hi - i am...

Hi - i am doing research and need an answer to something....if i submit a prescription to a drug store (let's say it is Teva's ProAir asthma drug) can a pharmacy choose to provide the same drug by a different manufacturer (if the script mentions Teva) or do they have to prescribe the drug made by Teva? Secondly, if they DO prescribe something else, how do they choose which Manufacturer? Does each retail pharmacy chain have a specific list of manufacturers that they get discounts from? If that is true, does that mean when I give the same script to Walgreens, CVS and Rite Aid respectively for Teva ProAir could I potentially be getting the drug but from a competitor to Teva that also sells basically the same thing under its own brand? Thanks and take your time. I know this is a complicated question, Pearl

Doctor's Assistant: After your first paid question, we offer a week's free trial membership when you can ask as many questions as you like. What medications do you take daily? Are you allergic to any medications?

How much will it cost to get this question answered? See above

Doctor's Assistant: It can cost anywhere from $10 to $100, depending on the type of issue and how much of the Pharmacist's time your question is expected to take (how complex and lengthy an answer you require). Anything else in your medical history you think the doctor should know?

Did you read my question? I already submitted it. Please see above

Hi there. You are speaking with Dr Jonathan. Please allow me a moment to prepare my response.

If a doctor checks off "do not substitute" on a prescription, the pharmacy filling it must dispense exactly what is written on the prescription. In the case of Proair, that is a brand name, so no other manufacturer can sell a product called Proair. There are other inhalers that contain the same medication, but under different brand names. However, for other medications, if nothing is specified on the prescription, then you will get the drug made by the manufacturer which the pharmacy decides to use.
Ask Your Own Pharmacy Question
Excluding a handful of medications, like Synthroid and Coumadin, the manufacturer is irrelevant because the active drug is tested by the FDA to be equivalent across all manufacturers.

I hope that wasn't too wordy.

OK, that makes sense. However, let's say the doctor says in the script "salbutamol" (which is the actual drug name) instead of Teva ProAir. And lets say that Merck and Teva both market "salbutamol" under different brand names. Then CVS can prescribe Teva's Proair salbutamol if they get a better discount from Teva, and Walgreens is allowed to prescribe Merck's version of salbutamol if they have a better contract with Merck. Is that right? thanks for the follow-up answer.
Albuterol would be the actual drug name in Proair. Yes that is correct. For your reference, the three main brand names of albuterol hfa inhalers in the U.S. are Proair, Ventolin, and Proventil. If albuterol is written on the prescription, you will get whichever one your pharmacy decides to stock.

Thank you. Got this information from Thomson's Cortellis Teva Pharma Pipeline report. Dated September 5, 2017. Refers to the drug name as salbutamol MDI, and one of the synonyms as albuterol. Not sure which is which, but the FDA patent number is ***** to the drug name. The client needs all of the associated patent work in addition to this explanation.(excerpt from the table below):Drug Name: salbutamol MDI, IVAX CorpKey Synonyms:
albuterol MDPI;ProAir HFA;Salamol CFC-Free;ProAir Dose Counter;Salamol
Steri-Neb;albuterol sulfate HFA;Albuterol Spiromax;albuterol sulfate;ProAir

P.S. I am trying to find some kind of source on the Web that backs up what you just told me....like "best practices for retail pharmacist" or something. I know this is a total crap-shoot but if you know of a manual or website that indicates that pharmacists are allowed to prescribe any manufacturer they choose if the backing FDA drug is the same, that would be great. Otherwise, no worries at all. Thanks again!
This is an excerpt from the FDA website: Distributors or repackagers of products listed in the Orange Book are not identified. Because distributors or repackagers are not required to notify FDA when they shift their sources of supply from one approved manufacturer to another, it is not possible to maintain complete information linking product approval with the distributor or repackager handling the products.

It sort of touches on it. But I'll give you the full link and maybe you can find your way to something more specific.

Thank you so much, Doctor. This is exactly what I needed. By the way, you were right about Albuterol. The Orange Book shows the two ProAir products, as ALBUTEROL SULFATE (main ingredient). I have taken alot of your time. Enjoy your weekend!Best,
Jen

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.
