India on Thursday said it is lodging with China a strong protest against fake anti-malarial 'Made-in-India' drugs detained by Nigerian authorities, maligning the Indian pharmaceutical industry for consignments which actually originated from the neighbouring country. "Taking serious note of the action by scrupulous elements to malign the Indian generic pharma industry, Embassy of India in Beijing, has been requested to lodge a strong protest with concerned Chinese authorities and also to impress upon them to take stringent action against such scrupulous elements," a commerce ministry statement said here. It said the government's Drug Regulatory Authority (NAFDAC) has reported about the detention of a large consignment of fake anti-malarial generic pharmaceuticals labelled 'Made in India' but produced in China.
