ALG-002 / v2.0
Peanut suspension
The existing technical example is assessed as a suspension under development. Clinical immunotherapy literature does not establish quality or dating of this local product.
Development dossier · No validated formula, clinical dosing schedule or established finished-preparation BUD.
Material and strength basis
Record Arachis hypogaea, form/milling, roasting or defatting, lot and allergenic contaminants. Distinguish food mass from total protein and individual-analyte content. A well-characterised material does not automatically establish suspension uniformity.
Redispersibility and syringe
Study particle distribution, settling, compact sediment and recovery after the intended shaking. Check clogging, dead volume, adsorption and actual withdrawal with the exact syringe/adapter. Assess delivery during the last container withdrawals too.
What PALFORZIA evidence covers
The FDA label covers a specific standardised powder with controlled doses. It directs emptying the dose into semisolid food and consuming promptly, and excludes liquid mixing for that administration. It does not establish dating for a premade oral suspension. Anaphylaxis, uncontrolled-asthma and eosinophilic-oesophagitis warnings concern the actual product and clinical assessment.
Dating and release
Require protein/analyte retention, uniformity, microbiology and in-use data for the exact matrix. Refrigeration does not replace a study. This dossier assigns no numerical BUD. Release requires technical and clinical agreement with results, not only a completed form.
