My first language is Finnish, which has a very straightforward correspondence between spelling and pronunciation. I would divide the drug names into four categories based on how they sound: Obviously a substance: Amantidine, Sildenafil Generic fantasy names / pronounceable strings with no meaning: Azafen, Clédial, Cymbalta, Desyrel, Edronax, Luvox Could be Tolkienian, but it's spelled wrong: Sintamil Could be Tolkienian, but the final syllable is wrong: Elronon, Eskalith, Nardil Additionally, the two Tolkien characters I had to guess were both kings of Gondor: Minalcar and Narmacil. Their names are in Quenya, while the commonly used names for elves etc. are in Sindarin, which sounds different.
