A Tibetan musical score from the 19th century. Sheet music is a handwritten or printed form of music notation that uses modern musical symbols to indicate the pitches (melodies), rhythms and/or chords of a song or instrumental musical piece.
Generic Ramelteon. Generic ramelteon is expected to become available as early as 2017, when ramelteon's patent expires. Until an approved version actually becomes available on the market, you should not purchase any so-called generic ramelteon products because these medicines may be fake, substandard, and potentially dangerous.
Generic Butrans. There are currently no generic Butrans (buprenorphine patch) products available in the United States. Although the first patent for Butrans expired in November 2010, it is likely that other patents prevent manufacturers from making a generic version. The next patent is set to expire in December 2015, which would be the earliest date a generic product could become available.
