Phenothiazines interactions

A confusing situation as the results are inconsistent. The concurrent use of phenytoin and the phenothiazines cited need not be avoided, but it would be prudent to watch for any signs of changes in serum phenytoin levels that would affect antiepileptic control. It is also worth remembering that phenothiazines may decrease the seizure threshold. In one study a trend towards increased seizure frequency was noted after phenothiazines were added, or doses increased. Also note that phenytoin may reduce levels of some phenothiazines. Whether all phenothiazines interact similarly is uncertain. [Pg.563]

When phenothiazine interacts with peroxide radicals, radicals of the corresponding azotoxide (XI), the EPR spectrum of which is shown in Fig. 40a, are also formed. [Pg.52]

The most commonplace substrates in energy-transfer analytical CL methods are aryl oxalates such as to(2,4,6-trichlorophenyl) oxalate (TCPO) and z s(2,4-dinitrophenyl) oxalate (DNPO), which are oxidized with hydrogen peroxide [7, 8], In this process, which is known as the peroxyoxalate-CL (PO-CL) reaction, the fluorophore analyte is a native or derivatized fluorescent organic substance such as a polynuclear aromatic hydrocarbon, dansylamino acid, carboxylic acid, phenothiazine, or catecholamines, for example. The mechanism of the reaction between aryl oxalates and hydrogen peroxide is believed to generate dioxetane-l,2-dione, which may itself decompose to yield an excited-state species. Its interaction with a suitable fluorophore results in energy transfer to the fluorophore, and the subsequent emission can be exploited to develop analytical CL-based determinations. [Pg.179]

Drugs that may interact with nitrates include alcohol, alteplase, aspirin, beta-blockers, calcium channel blockers, dihydroergotamine, heparin, nondepolarizing muscle relaxants, phenothiazines, phosphodiesterase inhibitors (eg, sildenafil, tadalafil, vardenafil), and vasodilators. [Pg.417]

Drugs that interact with oxybutynin include atenolol, digoxin, haloperidol, phenothiazines, amantadine, and anticholinergic agents. [Pg.660]

Hypersensitivity to the drug or any other component of the product (cross-sensitivity between phenothiazines may occur) comatose or greatly depressed states caused by CNS depressants or from any other cause (phenothiazines, clozapine, loxapine, molindone, pimozide, haloperidol) coadministration with other drugs that prolong the QT interval and in patients with congenital long QT syndrome or history of cardiac arrhythmias (mesoridazine, thioridazine, pimozide, ziprasidone see Drug..Interactions). [Pg.1100]

Drug/Lab test interactions Phenothiazines may produce false-positive phenylketonuria (PKU) test results. Phenothiazines may cause false-positive pregnancy test results. [Pg.1108]

Drugs that may interact with Gl anticholinergics include amantadine, atenolol, digoxin, phenothiazines, and tricyclic antidepressants. [Pg.1361]
