Understanding Sublingual ODTs
An orally disintegrating tablet (ODT) is formulated to dissolve in the mouth without the need for water. Specifically, sublingual ODTs are placed under the tongue, allowing the medication to be absorbed directly into the bloodstream through the oral mucosa. This route can bypass the gastrointestinal tract and first-pass metabolism in the liver, potentially leading to faster and more efficient drug absorption.

Advantages of Sublingual ODTs
Bypassing the Digestive System
Certain medications, such as peptides and hormones, can be degraded by stomach acids or enzymes, reducing their effectiveness. Sublingual administration allows these drugs to enter the bloodstream directly, potentially enhancing their bioavailability.
Avoiding First-Pass Metabolism
When drugs are absorbed through the digestive system, they often undergo first-pass metabolism in the liver, which can diminish their potency. Sublingual absorption circumvents this process, potentially leading to more consistent therapeutic effects.
Enhanced Convenience
Sublingual ODTs eliminate the need for water and swallowing, making them an excellent option for individuals with dysphagia or those seeking a more convenient medication regimen.
Proper Use of Sublingual ODTs
To ensure optimal absorption:
- Place the tablet under your tongue.
- Allow it to dissolve completely, which usually takes 1–2 minutes.
- Avoid eating or drinking for at least 5–10 minutes afterward.
- Follow to the dosing schedule recommended by your healthcare provider.
When Sublingual Delivery Is Most Beneficial
Sublingual ODTs may be particularly advantageous for:
- Peptide therapies
- Hormonal treatments
- Medications requiring rapid onset
- Patients with gastrointestinal sensitivities
- Individuals who have difficulty swallowing pills
What the Science Says
Research supports the clinical value of ODTs and sublingual delivery methods, especially in cases where faster onset, improved adherence, or enhanced bioavailability is needed.
Faster Onset and Better Compliance
A study published in the International Journal of Pharmaceutics found that ODTs may offer faster onset of action compared to standard oral tablets due to their direct absorption in the mouth and shorter time to dissolution. This can be especially beneficial for medications where rapid absorption improves outcomes or comfort.
Improved Bioavailability in Sensitive Medications
For certain peptides and protein-based therapies, oral delivery is notoriously difficult due to enzymatic degradation in the GI tract. A Journal of Controlled Release study explored sublingual delivery for peptide-based drugs and noted significantly improved absorption through the oral mucosa compared to traditional oral routes.
Enhanced Absorption Through Sublingual Delivery
🔬 A study conducted by iX Biopharma demonstrated that their sublingual semaglutide wafer (iXB 401) achieved approximately 20 times greater bioavailability compared to oral semaglutide (Rybelsus®) in a rat model, highlighting the potential of sublingual routes for peptide delivery.
A Sublingual Solution: Sermorelin ODT
Recognizing the benefits of sublingual delivery, Eden offers Sermorelin ODT, a sublingual tablet designed to stimulate growth hormone production. This formulation provides a convenient, needle-free alternative to injectable therapies, with the added advantage of not requiring refrigeration.
Conclusion: Smarter Delivery for Select Therapies
For certain medications—especially fragile molecules like peptides—sublingual delivery offers clear, research-backed advantages. By bypassing the gastrointestinal tract and first-pass metabolism, sublingual ODTs may improve bioavailability, provide faster onset of action, and simplify daily routines.
At Eden, we believe that how you take your medication matters. Our Sermorelin ODT is a thoughtfully compounded, sublingual tablet designed to offer a needle-free, convenient option for individuals seeking growth hormone support. As always, speak with your provider to determine whether this treatment is right for your goals and needs.
