New amantadine (Am) ion selective plastic membrane electrodes of both conventional and coated graphite types based on the ion-pair of amantadinium tetraphenylborate (Am-TPB) ion-pair are prepared. The conventional type electrode was fully characterized in terms of membrane composition, life span, pH, ionic strength and temperature. It was applied to potentiometric determination of amantadine in pure state and pharmaceutical preparation under batch and flow injection conditions. The selectivity of the electrode toward a large number of inorganic cations, sugars and amino acids was tested. The solubility product of the ion-pair and the formation constant of the precipitation reaction leading to the ion-pair formation were determined conductimetrically.

UI	MeSH Term	Description	Entries
D011199	Potentiometry	Solution titration in which the end point is read from the electrode-potential variations with the concentrations of potential determining ions. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
D000547	Amantadine	An antiviral that is used in the prophylactic or symptomatic treatment of influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The mechanisms of its effects in movement disorders are not well understood but probably reflect an increase in synthesis and release of dopamine, with perhaps some inhibition of dopamine uptake.	1-Aminoadamantane,Adamantylamine,Adekin,Aman,Amanta,Amanta-HCI-AZU,Amanta-Sulfate-AZU,Amantadin AL,Amantadin AZU,Amantadin Stada,Amantadin-neuraxpharm,Amantadin-ratiopharm,Amantadina Juventus,Amantadina Llorente,Amantadine Hydrochloride,Amantadine Sulfate,Amixx,Cerebramed,Endantadine,Gen-Amantadine,Infecto-Flu,Infex,Mantadix,Midantan,PMS-Amantadine,Symadine,Symmetrel,Viregyt,Wiregyt,tregor,1 Aminoadamantane,AL, Amantadin,AZU, Amantadin,Amanta HCI AZU,Amanta Sulfate AZU,AmantaHCIAZU,AmantaSulfateAZU,Amantadin neuraxpharm,Amantadin ratiopharm,Amantadinneuraxpharm,Amantadinratiopharm,Gen Amantadine,GenAmantadine,Hydrochloride, Amantadine,Infecto Flu,InfectoFlu,Juventus, Amantadina,Llorente, Amantadina,PMS Amantadine,PMSAmantadine,Stada, Amantadin,Sulfate, Amantadine
D017022	Flow Injection Analysis	The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
