DL-Panthenol (DL-Pantothenyl alcohol) is the alcohol analog of pantothenic acid (vitamin B5) and is thus a provitamin of B5. In organisms, it is quickly oxidized to pantothenate.

D-Panthenol (D-Pantothenyl alcohol) is an alcoholic analogue of D-pantothenic acid and cholinergic agent. D-Panthenol acts as a precursor of coenzyme A necessary for acetylation reactions and is involved in the synthesis of acetylcholine. Although the exact mechanism of the actions of D-Panthenol is unclear, it may enhance the effect of acetylcholine. D-Panthenol acts on the gastrointestinal tract and increases lower intestinal motility. It is also applied topically to the skin to relieve itching and to promote healing.

Pantethine (Pantomin) (Bis-pantethine) is a dimeric form of vitamin B5. Pantethine is less stable than pantothenic acid and tends to decompose over time if it is not kept refrigerated, so most vitamin B5 supplements are in the form of calcium pantothenate. It is available as a dietary supplement and is used to treat acne and improve the blood-cholesterol profile.

(R)-Pantetheine (Pantetheine) is the biologically active form of VB5 (pantothenic acid), which occurs in nature in various forms of Pantetheine-containing ligands (PCL). (R)-Pantetheine increases platelet cell membrane fluidity and inhibits platelet aggregation.
