Panthenol (Dexpanthenol): Pro-Vitamin B5 for Wound Healing and Skin Care
Panthenol (dexpanthenol, provitamin B5) is a stable precursor to pantothenic acid (vitamin B5), readily absorbed through the skin and converted to pantothenic acid in tissues. It is one of the most widely used ingredients in dermatology and wound care.
Used topically for wound healing acceleration, skin hydration, prevention of skin irritation, and treatment of minor skin damage. Also formulated as nasal spray for rhinitis, eye drops for dry eye, and oral supplement.
Mechanism of Action
Converted to pantothenic acid, a component of coenzyme A (CoA), which is essential for fatty acid synthesis, cellular energy metabolism (Krebs cycle), and synthesis of skin lipids. Promotes keratinocyte proliferation, epithelialisation, and collagen cross-linking. Has humectant properties — attracts and retains moisture in the stratum corneum.
Indications & Use
Topical: wound healing (minor wounds, burns, abrasions), dry and irritated skin (eczema, nappy rash, radiotherapy skin reactions), post-procedure skin care (after peels, laser). Nasal spray: dry nasal mucosa, rhinitis sicca. Eye drops: dry eye. Wound gel/ointment (Bepanthen, Pantoderm).
Dosage
Topical cream/ointment (typically 5%): apply 1–3× daily to affected area. No maximum dose for topical use. Nasal spray: 1–2 applications per nostril 2–3× daily. Eye drops: 1 drop 3–5× daily. Oral supplement: 5–10 mg/day.
Side Effects
Excellent tolerability profile. Rare: contact allergy (very uncommon given wide use). No known systemic toxicity with topical application. Safe in pregnancy, breastfeeding, neonates, and elderly.
Drug Interactions
No clinically significant drug interactions for topical use. IV dexpanthenol should not be given within 1 hour of suxamethonium (may enhance neuromuscular blockade — rare clinical relevance).
Contraindications
Known hypersensitivity to panthenol or any excipient (very rare). No other relevant contraindications for topical use.
Frequently Asked Questions
Is Bepanthen suitable for newborns?
Yes. Bepanthen (dexpanthenol 5% cream) is specifically recommended for nappy rash in newborns and infants. It is one of the safest topical preparations with no known toxicity in neonates and is widely used as standard care.
Can panthenol be used on open wounds?
Yes — in gel or ointment formulations, panthenol is specifically used for superficial wounds, burns, and abrasions to promote healing and prevent drying. It does not delay healing or cause infection risk at standard use.
Does panthenol help with hair?
Panthenol is widely used in hair care products. It penetrates the hair shaft, adds moisture and volume, reduces frizz, and may reduce hair breakage. However, it does not stimulate hair follicle growth or treat hair loss.
