China has
become the world's largest producer of antipyretic and analgesic drugs,
with the output of aspirin, paracetamol, analgin and other varieties
exceeding 10000 tons, and that of phenacetin, aminopyrine, antipyrine
and other varieties exceeding 1000 tons. At present, the output of
antipyretic and analgesic drugs in China is growing rapidly, and it is
expected that it will increase by about 8% in the future. The production
of intermediates for antipyretic and analgesic drugs is large and there
are many manufacturers. With the increase of antipyretic and analgesic
drugs, the intermedia have also obtained considerable development.
In
2003, the domestic consumption of paracetamol increased rapidly, and
the export also showed a rapid growth momentum. The export volume was
28163 tons, and the annual export volume increased by about twice
year-on-year. In the first half of 2004, although its export growth
slowed down, it still increased. From 2004 to May, the export volume of
paracetamol was 12501 tons, slightly higher than the same period last
year. Para aminophenol is an important intermediate for the synthesis of
paracetamol, which has also grown rapidly in recent years. At present,
the annual output of paracetamol in China is about 32000 tons. It is
estimated that by 2005, the domestic output of paracetamol will reach
more than 50000 tons, and the pharmaceutical industry will consume 45000
tons of paracetamol. With the application in other fields, the total
demand for paracetamol in 2005 will be about 50000 tons. The market gap
is large, and the development and utilization prospects are broad.
