503A AND 503B

Compounding pharmacy software that keeps the formula, the lot and the prescription together

A compounding pharmacy is a pharmacy that makes a preparation to order rather than dispensing a manufactured product, and federal law splits the work in two. Section 503A covers patient specific compounding and caps out of state distribution at 5 percent where the state has signed no memorandum of understanding. Section 503B outsourcing facilities register with FDA each year and report their products in June and December. Neurobird holds the formula, the lot and the prescription on one record.

The daily reality

What compounding pharmacies actually deal with

A formula is changed on a bench sheet and the previous version survives only in someone's memory.
A recall names a bulk substance lot and the search for every affected prescription starts in a paper log.
Beyond use dates are worked out per batch and stored per batch, so nothing warns you before one expires.

Why it stays broken

Compounding is manufacturing carried out inside a pharmacy, and pharmacy software was written to dispense. The dispensing system holds prescriptions, the bench sheet holds the formula, and lot numbers live in a bound book. Nothing links a finished preparation back to the bulk substance lot it came from, which is the first thing a recall asks for.

Contaminated compounded drugs from one Massachusetts pharmacy caused more than 750 infections and more than 60 deaths across 20 states in 2012.

Outsourcing facilities are a category of compounders established in 2013 by the Drug Quality and Security Act.

What it does

Neurobird Compounding Pharmacy Document Automation Platform

One record per preparation: the master formula and its version, every component lot that went in, the beyond use date, who compounded it and which prescription or order it left on.

  • 1Version every master formula so the sheet used on a given day can still be produced years later
  • 2Tie each component lot to the preparations made from it, in both directions, for recall
  • 3Calculate and hold beyond use dates against the preparation rather than a shelf label
  • 4Keep registration, reporting and equipment records where an inspector can be walked through them

What changes with Neurobird Compounding Pharmacy?

The same work, read left to right: how it runs today, and how it runs once the record is in one place.

Who is this for?

The same bench, three different operations.

503A pharmacy

Patient specific compounding

Every preparation answers to a prescription. You need the formula version, the lots and the prescription joined so a recall is a query, not a search.

Sterile compounder

You run a cleanroom

Environmental monitoring, competency evaluations and equipment calibration all have their own intervals. You need them on the same calendar as the batches.

503B outsourcing facility

You supply office stock

Registration renews annually and product reports are due twice a year. You need the product list to come out of the batch records rather than a spreadsheet.

How does Neurobird Compounding Pharmacy work?

  1. Version the formula

    A master formula is an object with versions and effective dates, so the sheet used on a given day is recoverable rather than reconstructed.

  2. Bind the lots

    Each component lot is attached to the preparation it went into, so one query answers both recall directions instead of a week in a log book.

  3. Date and dispense

    Beyond use dates attach to the preparation and travel with it, and the prescription or the facility order that received it stays linked to the lot.

What the rules say about compounded preparations

The law that split compounding in two, the distribution cap, the registration cycle and the reason all of it exists.

Key terms

What is the difference between 503A and 503B?
Section 503A covers traditional pharmacy compounding against patient specific prescriptions. Section 503B created outsourcing facilities, which register with FDA, work to current good manufacturing practice and may supply office stock without a patient name. A 503A pharmacy without a state memorandum of understanding may send only 5 percent of its compounded products out of state.
What is a master formula record?
It is the controlled recipe for a preparation: components, quantities, equipment, procedure, beyond use dating and the checks required. Versioning it matters because a batch made two years ago has to be explainable against the sheet in force on that day, not the current one.

Does this replace our pharmacy dispensing system?

No. It sits beside it. The dispensing system handles prescriptions and billing. This holds the batch: formula version, component lots, beyond use date and the release, which is the part a recall or an inspection actually asks about.

Can it answer a recall in both directions?

That is the point of holding lots on the preparation. From a bulk substance lot you get every preparation made with it, and from a preparation you get every lot that went into it.
