Diazoxide: From Hyperinsulinemic Hypoglycemia to Alopecia
One-Sentence Summary
Diazoxide is a KATP channel opener, originally used to treat hyperinsulinemic hypoglycemia, including insulinoma and congenital hyperinsulinism. The TxGNN model’s top-ranked predictions are hair-related conditions. The most clinically meaningful of these is Alopecia (score 0.9991), supported by 0 clinical trials and 6 publications. These are mostly indirect: reviews, case reports and one animal study. This report evaluates alopecia (rank 4) as the lead candidate. The three higher-scoring predictions have no trials or literature at all, so they are covered only in the notes below the Quick Overview table.

Notes on the other top predictions:
- Hypotrichosis simplex of the scalp, congenital hypotrichosis milia and diffuse alopecia areata (ranks 1–3) have no trials or literature (L5).
- Hypertrichosis (rank 7) is an adverse effect of diazoxide, so the prediction is not a treatment opportunity.
- Autosomal dominant hyperinsulinism due to Kir6.2 deficiency (rank 10) falls within the original indication class. However, KATP channel variants often impair diazoxide response, and no specific evidence was retrieved.
Why is This Prediction Reasonable?
Detailed mechanism of action data is not available in the data compiled for this report. Diazoxide is known to open KATP channels (SUR/Kir6.x). In the pancreas this suppresses insulin release, which explains its use in hyperinsulinemic hypoglycemia.
The link to hair disorders comes from a well-documented side effect: hypertrichosis. It has been reported in neonates and children on systemic diazoxide. In a Japanese post-marketing survey of 384 patients, it was the most common adverse reaction (8.6%). Diazoxide shares this property with minoxidil, whose sulfate metabolite is also a KATP opener. Minoxidil is a recognised hair-growth agent.
Supporting this, topical diazoxide induced hair regrowth in the bald scalps of macaques (PMID 2085505, PMID 8326148). The original and new indications are not pharmacologically related. The prediction rests on a shared channel-opening mechanism and a side-effect phenotype, not on any disease-pathway similarity. The high TxGNN score likely reflects hair-phenotype network proximity.
For alopecia areata (rank 3), the immune-mediated follicular attack is not addressed by KATP opening.

- Others: bupropion, morphine, dronabinol.
Reported adverse effects in the literature: hypertrichosis, fluid retention, cardiac failure, necrotizing enterocolitis in neonates, petechial rash and acute renal failure.
Package insert warnings and contraindications were not available. Please refer to the package insert for authoritative safety information.
Conclusion and Next Steps
Decision: Hold
Rationale: The predictions are driven by the hypertrichosis side effect, and the evidence is limited to a macaque study, reviews and case reports. No human trial exists for any hair-loss indication. Systemic diazoxide also carries a substantial safety burden: fluid retention, cardiac failure and glucose interactions. The registered oral capsules are therefore poorly suited to a cosmetic or dermatological use.
To proceed, the following is needed:
- Package insert warnings and contraindications, which currently block safety screening
- Mechanism of action data (MOA)
- Human data for a topical diazoxide formulation in androgenetic alopecia, with a registered topical product or a development plan
- Comparison against minoxidil, the existing KATP-opener standard, to show added value
- Systemic exposure and safety data for topical use
- For the Kir6.2 hyperinsulinism prediction (rank 10), a separate review of variant-specific diazoxide responsiveness in the congenital hyperinsulinism literature
