Pharmacy partnerships503A and 503B

The pharmacy partner matched to what you prescribe.

Northstra Health is contracted with leading compounding pharmacies across the United States. Most practices already purchase compounded medications. The question is whether their pharmacy carries what they prescribe, ships on a schedule the clinic can absorb, and holds up under a board inspection.

How the pharmacy channel works

Prescriptions and office-use orders routed to the facility type the medication requires.

Two sides

Built for practices and pharmacies.

The partnership only works if it works for both.

For practices

The right partner, without the guesswork

Qualification against catalog, facility type, turnaround, and inspection history, with one point of contact through the transition.

For pharmacy partners

Qualified prescribers and territory growth

Introductions to practices whose prescribing matches the catalog, prioritized by a proprietary provider scoring model and supported through onboarding.

Facility types

503A and 503B, side by side.

Insights

From our pharmacy practice.

How we think about routing and partner quality.

Compounded medication capsules
Pharmacy

The compounding decision most practices get wrong.

Routing is the decision that matters: patient-specific prescriptions belong at a 503A pharmacy, office-use stock at a 503B outsourcing facility. Many practices need both and find out only after onboarding stalls.

Partner quality is a safety decision.

Outsourcing facilities enter and leave the federal registry more often than most practices realize. We qualify every partner on licensure, inspection history, turnaround, and catalog depth before a practice places its first order.
