Phenytoin is classified as a hydantoin derivative and despite its narrow therapeutic index, it is one of the most commonly used anticonvulsants.[A33595,A188832,A189219] Since it's introduction about 80 years ago, phenytoin has not only been established as an effective anti-epileptic, but has also been investigated for several other indications such as bipolar disorder, retina protection, and wound healing.[A188826,A188832] Clinicians are advised to initiate therapeutic drug monitoring in patients who require phenytoin since even small deviations from the recommended therapeutic range can lead to suboptimal treatment, or adverse effects.[A189219,A35884] Both parenteral and oral formulations of phenytoin are available on the market.
Azelastine is a phthalazine compound having an oxo substituent at the 1-position, a 1-methylazepan-4-yl group at the 2-position and a 4-chlorobenzyl substituent at the 4-position. It has a role as a H1-receptor antagonist, an anti-allergic agent, an anti-asthmatic drug, a bronchodilator agent, a platelet aggregation inhibitor and an EC 1.13.11.34 (arachidonate 5-lipoxygenase) inhibitor. It is a member of phthalazines, a tertiary amino compound and a member of monochlorobenzenes.
