What Are Oral Dissolvable Strips?
Oral dissolvable strips (ODS) are thin, polymer-based films designed to dissolve rapidly on the sublingual or buccal mucosa. Originally developed for pharmaceutical applications such as antiemetics and analgesics, this technology has been adapted for research-grade peptide delivery with remarkable results.
Unlike traditional lyophilized powder that requires reconstitution and subcutaneous injection, ODS formulations offer a non-invasive pathway for compound administration in research settings.
How Sublingual Absorption Works
The sublingual region—beneath the tongue—is rich in blood vessels and highly permeable epithelial tissue. When a strip is placed sublingually, the polymer matrix dissolves within 30–90 seconds, releasing the active compound directly into the capillary bed.
This bypasses first-pass hepatic metabolism, meaning the compound enters systemic circulation without being degraded by liver enzymes. For peptides, this can result in significantly higher bioavailability compared to oral capsule delivery, where gastric acid and enzymatic degradation can destroy the peptide before absorption occurs.
Advantages Over Traditional Delivery
- No Reconstitution Required — Eliminates the need for bacteriostatic water, syringes, and sterile technique
- Precise Dosing — Each strip contains a metered, uniform dose manufactured under cGMP conditions
- Improved Stability — The dry film matrix protects peptides from moisture-induced degradation
- Room Temperature Storage — Many ODS formulations remain stable without refrigeration
- Rapid Onset — Sublingual absorption can begin within minutes of application
The cGMP Manufacturing Process
Manufacturing oral dissolvable strips at pharmaceutical grade requires current Good Manufacturing Practice (cGMP) facilities. The process involves dissolving the active peptide into a polymer solution (typically pullulan or HPMC-based), casting the solution onto a release liner in a controlled-thickness film, and then drying under precise temperature and humidity conditions.
Each strip is then cut to exact dimensions, individually packaged in moisture-barrier sachets, and subjected to quality control testing including content uniformity, dissolution rate, and stability assays. This level of manufacturing precision ensures batch-to-batch consistency that is difficult to achieve with traditional compounding.
ROEHN's oral dissolvable strips are manufactured in FDA-registered, cGMP-compliant facilities with full batch testing and certificate of analysis documentation for every lot produced.
