Amantadine aerosols in normal volunteers: pharmacology and safety testing. 1979

F G Hayden, and W J Hall, and R G Douglas, and D M Speers

The acceptability and pharmacology of intermittent aerosol administration of amantadine was assessed in healthy volunteers. Amantadine solutions of 2.5, 1.5, or 1.0 g/100 ml were used for 12 30-min, twice-daily aerosol treatments in 15 subjects. Overall, the aerosol treatments were well tolerated. During and up to 1 h after aerosol exposures, nasal irritation, rhinorrhea, dysgeusia, or a combination of symptoms was experienced by some of the subjects receiving either of the two higher amantadine concentrations. Aerosol treatments were associated with small but statistically significant decreases in maximal expiratory flow rates. One hour after aerosol treatments with the 1.0-g/100 ml solution, amantadine levels in nasal wash samples (mean, 30.3 micrograms/ml; range, 1.7 to 108 micrograms/ml) greatly exceeded blood and nasal wash levels reported after oral administration. Amantadine can be administered safely by small-particle aerosol to humans in doses that could be expected to exert an antiviral effect in influenza A virus infections.

D000336	Aerosols	Colloids with a gaseous dispersing phase and either liquid (fog) or solid (smoke) dispersed phase; used in fumigation or in inhalation therapy; may contain propellant agents.	Aerosol
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
D001419	Bacteria	One of the three domains of life (the others being Eukarya and ARCHAEA), also called Eubacteria. They are unicellular prokaryotic microorganisms which generally possess rigid cell walls, multiply by cell division, and exhibit three principal forms: round or coccal, rodlike or bacillary, and spiral or spirochetal. Bacteria can be classified by their response to OXYGEN: aerobic, anaerobic, or facultatively anaerobic; by the mode by which they obtain their energy: chemotrophy (via chemical reaction) or PHOTOTROPHY (via light reaction); for chemotrophs by their source of chemical energy: CHEMOLITHOTROPHY (from inorganic compounds) or chemoorganotrophy (from organic compounds); and by their source for CARBON; NITROGEN; etc.; HETEROTROPHY (from organic sources) or AUTOTROPHY (from CARBON DIOXIDE). They can also be classified by whether or not they stain (based on the structure of their CELL WALLS) with CRYSTAL VIOLET dye: gram-negative or gram-positive.	Eubacteria
