Description
Phenytoin Product Overview
Phenytoin (C15H12N2O2) is a white crystalline powder that is practically insoluble in water. For capsules and injections, producers usually use its sodium salt, which dissolves much better. Introduced in 1938, it is one of the oldest antiepileptic APIs still in wide use.
Pharmaceutical companies use phenytoin in chewable tablets, oral suspensions and, as the sodium salt, in capsules and injections. Because the gap between effective and toxic levels is narrow, regulators require tight control of dissolution and bioequivalence, which makes API consistency particularly important. Veterinary producers use it in some products for dogs.
Newer antiepileptic APIs in our range include Levetiracetam, Lamotrigine and Carbamazepine. Zyntex supplies phenytoin from qualified producers, only to licensed pharmaceutical companies.
