* FDA chief says important for India to work with foreign regulators
* Indian regulator says will follow own quality standards
* FDA visit follows sanctions against Indian drugs firms

MUMBAI, Feb 18 (Reuters) - The head of the U.S. Food and Drug Administration (FDA) called for more collaboration among regulators to improve drug quality and safety as she wrapped up a visit to India after recent import bans on drugs from a handful of plants in the country.
In recent months the FDA has banned the import of drugs and drug ingredients from leading Indian manufacturers including Ranbaxy Laboratories and Wockhardt, citing quality concerns.
The bans threaten the image and market share of India's $14 billion pharmaceuticals sector in the United States. India is second only to Canada as a drug exporter to the United States, where it supplies about 40 percent of generic and over-the-counter drugs.
"We think this is a critical moment in time, when we have to think and act in new ways, and that requires real commitment as national regulators to work as a coalition of global regulators," FDA Commissioner Margaret Hamburg told reporters.
"And that is why it is so important that the Indian regulator really joins us at the table, because they are so important in the global marketplace for medical products."
Hamburg met regulatory and health ministry officials as well as executives of drugmakers including Ranbaxy and Wockhardt.
Quality was the central theme of Hamburg's visit, which included a trip to the Taj Mahal.
"It was evident," Hamburg wrote in a blog post on Friday, "that those responsible for building the Taj and those that are preserving the centuries-old structure are committed to extraordinary quality."
She said that "vision of quality and care" remained with her as she met executives from Indian drug exporters.
FDA ACTION NOT BINDING
During the visit, Hamburg and ministry officials signed a statement of intent to achieve, among other things, "convergence in regulations in keeping with international standards".
The agreement provides for U.S. and Indian regulators to inform each other before inspecting drugmakers' plants, so host-country inspectors can join as observers.
The Drug Controller General of India on Monday told Reuters that he sees scope for India's Central Drugs Standard Control Organization (CDSCO) working with the FDA and improving regulatory practice, adding that the Indian regulator will continue to follow its own quality standards.
"We don't recognise and are not bound by what the U.S. is doing and is inspecting," G.N. Singh said. "The FDA may regulate its country, but it can't regulate India on how India has to behave or how to deliver."
Industry officials in India say that weak domestic regulatory oversight and a lax approach to quality control by some drugmakers means that a large number of sub-standard drugs reach the market undetected.
Singh, however, said his agency inspects manufacturing facilities in India regularly and that it plans to raise the number of inspectors to 5,000 in three to five years, from about 1,500 now.
U.S. GENERIC DEMAND
Most of the drugs that Ranbaxy, Wockhardt and their Indian peers, including Dr Reddy's Laboratories and Lupin , export to the United States are cheaper copies of drugs with expired patent protection.
Demand for such drugs, known as generics, is rising in the United States, where the government is pushing to reduce healthcare costs. With increased demand has come greater regulatory scrutiny in India, which has the largest number of FDA-approved plants outside the United States.
The FDA inspected 111 Indian plants last year, compared with 72 in 2010, the regulator's data shows. The number of inspections in China rose to 78 from 48.
Last month the FDA banned imports from Ranbaxy's fourth and final Indian plant, meaning that the company can only sell drugs from its U.S. factory.
The FDA acted similarly in November against a second Wockhardt plant, which made generic versions of AstraZeneca's hypertension drug Toprol, citing flaws in the manufacturing process.
As a result of the sanctions, the companies face delays in selling new generics in their biggest market as well as the cost of hiring external consultants to ensure compliance with the FDA's manufacturing standards.
