Guides for pharmacies that make and ship medicine

503A vs 503B explained with the statute in hand: who regulates each, the prescription requirement, cGMP, registration and fees, reporting, bulk substance lists, labeling, interstate limits, inspection, testing, and what each model demands from your software.

A working USP <800> checklist for compounding pharmacies handling hazardous drugs: the HD list and assessment of risk, designated person, facility and engineering controls, receiving and storage, PPE, compounding, deactivation and cleaning, spills, environmental wipe sampling, medical surveillance, and the records that prove it.

What 21 CFR Part 11 requires of electronic records and electronic signatures in a compounding pharmacy or 503B: when it applies, §11.10 controls, audit trails, §11.50/§11.70 signature manifestation and linking, §11.200 two-component signatures, §11.300 password controls, validation — and why a signed PDF on a shared drive fails.

What serialization and the Drug Supply Chain Security Act mean for pharmacies: the product identifier, transaction data, the phased timeline and 2025–2026 dispenser deadlines, what a dispenser must do, why compounded drugs are excluded and why compounders serialize anyway, GS1 GTIN/SGTIN/SSCC/EPCIS, and per-unit recall.

How to ship temperature-sensitive compounded medications — GLP-1s, hormones, injectables — to patients reliably: USP storage definitions, what USP <797> and <1079> expect, qualifying packout against seasonal profiles, choosing carrier and service by lane, handling excursions with stability data, patient delivery, and the records that prove integrity.

A practical sequence for automating pharmacy fulfilment: make work visible as tasks, dispatch it, gate the stations with scans, then add machines that pull tasks from the same queue. What a warehouse execution system is, why it comes before robots, the pharmacy-specific overlay, and how to evaluate vendors on what is shipped.

How to run a compounded GLP-1 programme without buckling: API intake and licence gating, a daily refill run, cold-chain packout and excursion handling, strength variants and serials, API supply forecasting, wave-based floor work, and the numbers to watch each morning.

What breaks as a compounding pharmacy grows from a hundred orders a day to a thousand, in the order it breaks: intake, the floor, inventory and API supply, the batch record, visibility, and the second site. For each, the mechanism that fixes it and how to know you need it.

A practical roadmap for opening a compounding pharmacy: choosing 503A or 503B, state and DEA licensing, facility and cleanroom under USP <795>, <797> and <800>, equipment and staffing, the record system you need from day one, sourcing suppliers, and how your first orders will arrive.
