As to amphocetrin and voriconazole, I simply don't know. Ampho is impossible to score in my jurisdiction, except for IV treatments for hospital patients, and voriconazole and other new-generation azoles are prohibitively expensive here (up to $20k for a course of treatment).
...fluconazole, on the other hand, goes for $0.60 a pop, which makes it the poor man's alternative (but DAMN is it fatiguing as hell). I prefer my itraconazole @ $1.50 a pill. For me at least, it is WAY milder on the system, yet if you take it correctly, with food and acidic drink such as lemonwater, it seems to work just as well.
Then again, these things seem to differ - I take Rumikoz-brand generic itra by Valenta. My pharmacy once ran out and stuck me with similarly-priced Irunin-brand generic itra by VeroPharm, and that stuff did nothing whatsoever for me. I was like what the hell for a couple days, and then noticed barely-digested capsules floating around in the toilet bowl. Apparently, that crap's capsule design just doesn't dissolve properly sometimes. Pity this isn't America, where I could sue their asses for a couple mil... :(
