State of the Art: Oral GH Secretagogues and Their Clinical Future
Comprehensive review of orally active GH secretagogues including their pharmacology, clinical trial results, and therapeutic potential across GH deficiency, aging, and catabolic states.
Quick Facts
What This Study Found
Oral GH secretagogues effectively increase GH and IGF-1 through a specific receptor, with clinical potential spanning GH deficiency, aging, and catabolic states, though their optimal therapeutic role remained to be defined.
Key Numbers
How They Did This
Comprehensive review of published preclinical and clinical data on oral GH secretagogues.
Why This Research Matters
This review represented the most complete clinical assessment of oral GH secretagogues available at the time, helping define where these agents fit in endocrine therapeutics and identifying which clinical applications showed the most promise.
The Bigger Picture
The development of oral GH secretagogues represented a potential paradigm shift in treating GH-related disorders. Instead of daily GH injections, patients could potentially take a pill that stimulates natural GH production. This review captured the field's optimism while noting that optimal clinical applications were still being defined.
What This Study Doesn't Tell Us
1998 review — clinical trial database was still developing. Long-term outcome data not available. The therapeutic niche for oral GH secretagogues versus GH replacement was not yet resolved.
Questions This Raises
- ?Will oral GH secretagogues replace GH injections for any indications?
- ?What are the long-term metabolic effects of chronic GH secretagogue use?
- ?Can oral GH secretagogues improve outcomes in critically ill catabolic patients?
Trust & Context
- Key Stat:
- Effective oral GH stimulation Multiple oral compounds demonstrated consistent GH and IGF-1 elevation in clinical trials across diverse patient populations
- Evidence Grade:
- Comprehensive clinical review in Annals of Medicine. Synthesizes substantial preclinical and clinical evidence but reflects early-stage clinical development.
- Study Age:
- Published in 1998, this review captures the peak of pharmaceutical interest in oral GH secretagogues. Many compounds discussed did not ultimately reach market, though MK-677 remains widely studied.

What do these levels mean? →Frequently Asked Questions
What makes a GH secretagogue 'orally active'?
Most peptide-based GH releasers are destroyed by digestion and must be injected. Orally active secretagogues are non-peptide molecules that survive digestion and absorb through the gut, allowing them to be taken as pills.
Did oral GH secretagogues ever become approved medications?
Despite promising clinical trial results, most oral GH secretagogues from this era did not achieve regulatory approval for GH-related indications. However, MK-677 continues to be studied in clinical trials for various conditions.
