Eloralintide- Summary
- Dermorphin is a naturally occurring heptapeptide opioid isolated from the skin of South American phyllomedusine frogs. It is one of the most potent endogenous mu-opioid receptor agonists known, approximately 30-40 times more potent than morphine by weight. Explored for pain management and fatigue modulation.
- Eloralintide is a long-acting amylin analog under development by OPKO Health. Amylin is co-secreted with insulin and regulates post-meal glucose by slowing gastric emptying, suppressing glucagon, and promoting satiety. Eloralintide is designed for once-weekly dosing, differentiating it from the short-acting pramlintide (Symlin). It is being studied for obesity and type 2 diabetes as a complement to GLP-1 based therapies.
- Half-Life
- Estimated 30-60 minutes (longer than endorphins due to D-Ala)
- ~7 days (estimated, long-acting design)
- Admin Route
- Subcutaneous (research), Intrathecal (research), Intranasal (research)

- Typical Dose
- Not established for human use; research doses vary widely
- Under investigation in Phase 1/2 trials
- Frequency
- Not established
- Once weekly
- Key Benefits
- Potent analgesia superior to morphine on a per-weight basis
- May reduce perception of fatigue in high-intensity activity
- Longer-lasting than endogenous opioids due to D-amino acid substitution
- Research tool for mu-opioid receptor pharmacology
- Potential therapeutic application in refractory pain
- Once-weekly dosing (vs multiple daily injections for pramlintide)
- Appetite suppression via central amylin receptor activation
- Reduction in post-meal glucagon secretion
- Complementary mechanism to GLP-1 agonists for combination therapy
- Slows gastric emptying for prolonged satiety
- Potential additive weight loss when combined with GLP-1 agents
