Pharma Formulation Support

Develop and optimize inhalation and nasal formulations for stability, performance, and delivery using lab-scale formulation tools.

We work with solutions, suspensions, and dry powders using spray drying, milling, bench chemistry, and HPLC testing for API and impurities.

Purpose & when to use

Pharma formulation support helps inhalation and nasal product teams turn choices about the active, excipients, solvents, propellants, and processing into testable solution, suspension, and dry-powder candidates. ARE Labs uses low-temperature spray drying, milling, pH, osmolality, and HPLC assay or impurity checks to connect development-stage CMC decisions with USP <601>, FDA MDI / DPI / nasal, and ISO 17025 quality expectations:

  1. FDA development-stage CMC screening for MDI, DPI, nebulizer, or nasal prototypes using excipient, solvent, propellant, and preservative design matrices.
  2. USP <601> inhalation formulation iteration using spray drying, milling, and paired PSD or emitted-dose checks for candidate powders.
  3. ICH Q8 / Q9 / Q10 risk-based formulation studies using HPLC, pH, and osmolality data to rank stability and manufacturability risks.
  4. FDA MDI / DPI / nasal comparability support using matched batches, controlled process logs, and performance tests after formulation or component changes.
  5. USP <1601> nebulization support using suspension or solution optimization, re-dispersion checks, and aerosol-output readouts for liquid formulations.

Use pharma formulation support when composition, processing, or storage behavior could affect aerosol performance, impurity profile, or dose consistency. The method plan connects each formulation variable to the downstream testing needed for the next CMC decision.

Built for inhalation, nasal, and spray formulations

Formulation programs serve drug-delivery and spray platforms where FDA, USP, ICH, and device constraints shape composition, process choice, and performance confirmation.

Setup configurations

A formulation support study begins with the decision the customer needs to make: screen formulation factors, produce a powder, improve a suspension, or determine how stability affects performance. Before materials enter the lab, the study setup defines composition ranges, batch size, process settings, storage state, analytical checks, and any paired aerosol tests.

Sample matrix

API, excipients, solvent, propellant, preservative, concentration, and composition constraints documented for each candidate.

Exposure profile

Spray-drying, milling, mixing, evaporation, storage, and pull conditions defined before batch preparation.

Sample numbers

Screening runs, confirmatory batches, retained samples, and paired test replicates sized to the formulation decision.

Calibration & verification

Balances, pH, osmolality, HPLC calibration, and process settings checked before and during the campaign.

Chain of custody

Batch labels, preparation records, storage transfers, analytical handoffs, and final disposition recorded for each candidate.

Quality anchors for formulation decisions

Formulation studies need a clear quality posture before screening begins. Defining it early sets expectations for method controls, batch records, analytical checks, paired performance confirmation, and report language.

  • USP <601>AccreditedInhalation and nasal performance checks when paired with aerosol testing.
  • ICH Q8 / Q9 / Q10AlignedQbD, risk management, and pharmaceutical quality-system framing.
  • FDA MDI / DPI / nasalAlignedDevelopment-stage CMC and submission-facing expectations for OINDP programs.

Key data outputs & reporting

Each formulation support study provides the composition, process, analytical, and decision records needed to compare candidates. Reports document batch recipes, process settings, storage history, pH, osmolality, HPLC assay or impurity results, and paired aerosol readouts when included. They also explain why each formulation was advanced or rejected. Data are organized by candidate, factor level, condition, pull point, and endpoint.

Primary outputs

  • Composition and process logs covering batch recipe, spray-drying or milling settings, mixing steps, and storage state.
  • API assay, impurity, pH, osmolality, yield, appearance, and re-dispersion summaries by candidate and condition.
  • Decision tables linking formulation variables to stability, manufacturability, PSD, emitted dose, plume, or aerosol-output outcomes.

QA / QC & data integrity

Formulation decisions depend on a clear record of how each candidate was prepared, stored, sampled, and measured. QA / QC records cover instrument checks, batch identity, storage state, analytical suitability, repeat preparations, retained samples, and reviewer-ready notes. They also track each handoff from formulation work through aerosol or chemistry readouts.

Calibrated balances, pH meters, osmometers, and HPLC systems verified before use.

Batch records capturing raw materials, lot identity, process settings, yield, appearance, and deviations.

HPLC system suitability, calibration verification, blanks, and sample-sequence controls where assay or impurity data are reported.

Duplicate preparations or confirmatory batches for candidates that advance beyond screening.

Controlled storage, pull-point logs, and chain-of-custody records for retained or stability-linked samples.

Common questions

Questions about formulation often arise as pharmaceutical development, CMC, device, analytical, and regulatory teams turn an active ingredient and device concept into testable candidates. The answers below cover liquid and powder formulations, excipient screening, impurity tracking, paired aerosol testing, stability links, and study deliverables. If your active, device, or regulatory framework requires a different setup, contact ARE Labs to discuss the study.

Q.Can you support both liquid and dry-powder formulations?
A.Yes. We support solutions, suspensions, and dry powders using mixing, rotary evaporation, spray drying, milling, pH, osmolality, and HPLC checks. When needed, we pair promising candidates with aerosol performance testing.
Q.Can you track impurities and degradation?
A.Yes. HPLC assay and impurity profiling can be included in screening or stability-linked pulls, allowing formulation choices to be compared by chemical stability as well as appearance and performance.
Q.How do you choose a formulation path?
A.We begin with the target product profile, device constraints, active stability, route of delivery, and CMC decision. From there, we determine whether the first pass should use solution, suspension, powder, or parallel screening paths.
Q.Can aerosol testing be included with formulation work?
A.Yes. PSD, emitted dose, plume, spray pattern, or aerosol-output studies can be paired with formulation batches. This ties changes in composition to measured delivery outcomes.
Q.What do I receive after the study?
A.Deliverables usually include a PDF report, batch records, CSV or XLSX datasets, assay tables, trend plots, comparison figures, and the rationale for candidate selection tied to the agreed decision.
