None (16) ·
Positive allosteric modulator of the GABA<sub>A</sub> receptor at the benzodiazepine binding site; increases frequency of Cl<sup>−</sup> channel opening, producing anxiolytic, sedative, hypnotic, anticonvulsant, and skeletal-muscle relaxant effects. (1) ·
'"`UNIQ--vote-0000001D-QINU`"' '''QT prolongation''' risk at high doses prompted the FDA's 2015 caution against use in patients with prolonged QT or with concurrent QT-prolonging medicines'"`UNIQ--ref-0000001E-QINU`"'. (1) ·
'"`UNIQ--vote-00000D7A-QINU`"' Substantial QT-interval prolongation — the most QT-prolonging fluoroquinolone — limits use in patients on other QT-prolonging agents or with electrolyte abnormalities'"`UNIQ--ref-00000D7B-QINU`"'. (1) ·

'"`UNIQ--vote-00001284-QINU`"' Systemic oral ketotifen (available outside US) has historical use for asthma adjunct therapy via the same dual mechanism, but oral use produces sedation and weight gain — the topical ophthalmic application largely avoids both'"`UNIQ--ref-00001285-QINU`"'. (1) ·
'"`UNIQ--vote-000013B1-QINU`"' Topical application minimizes systemic antihistaminic burden; the characteristic bitter taste with nasal use (drainage to oropharynx) is the main tolerability issue'"`UNIQ--ref-000013B2-QINU`"'. (1)
uses:
No approved medical problem. Encountered as a designer/research benzodiazepine and, increasingly, as an adulterant in illicit opioid supplies. (1) ·
