A mainland pharmaceutical company is awaiting government approval to market a Chinese version of Viagra - which it plans to name Jin Ge, loosely translated as gold sword."
Since the drug sildenafil citrate became widely available in 1998 after its discovery by scientists at the US pharmaceutical giant Pfizer, Viagra has become the prime treatment for erectile dysfunction among men globally.
The genuine product enjoys a near monopoly in China, with annual sales of one billion yuan (HK$1.25 billion).
But the manufacture and sale of knock-offs, or "generic Viagra," is common in the mainland, where Pfizer's patent claim is rarely enforced.
Now the Guangzhou Baiyunshan Pharmaceutical's "Jin Ge" is awaiting official blessing from the China Food and Drug Administration, which it expects this year.
