2,4-Diaminopyridine Use and Manufacturing

2,4-Pyridinediamine was studies for its interaction with cholinesterase inhibitors, neostigmine (N390010) and edrophonium (E336000) as a combined treatment for the restoration of muscle contraction. E xperiments have shown the doses of neostigmine and edrophonium could be halved when they were combined with a small small amount of 2,4-pyridinediamine without apparent loss of antagonistic potency.
