UPDATE 1-Generic drugmaker Endo tops estimates, raises revenue forecast

(Adds details, shares, forecast)

Aug 8 (Reuters) - Endo International Plc reported a higher-than-expected quarterly profit, buoyed by higher sales from its sterile injectibles and U.S. branded drugs businesses, and the generic drugmaker raised its 2017 revenue forecast.

Endo's shares were up 5.6 percent at $9.83 before the bell on Tuesday.

The Dublin, Ireland-based drugmaker raised its full-year revenue forecast to $3.38 billion to $3.53 billion from $3.45 billion to $3.60 billion.

Excluding items, Endo earned 93 cents per share, above the average analyst estimate of 73 cents per share, according to Thomson Reuters I/B/E/S.

However, total revenue fell 4.9 percent to $875.7 million, hurt by weakness in Endo's U.S. generics business, but came in ahead of analysts' average estimate of $836.4 million.

Net loss from continuing operations was $696 million, or $3.12 per share, in the second quarter ended June 30, from a profit of $389.8 million, or $1.75 per share, a year earlier.

The drugmaker paid impairment charges of $725 million in the quarter, partly related to the withdrawal of its opioid painkiller Opana ER and the shutdown of its Alabama manufacturing facility.

Endo's results come a week after the world's No. 1 generics drugmaker Teva Pharmaceutical Industries Ltd posted a steeper-than-expected drop in its second-quarter earnings, hurt by accelerated price erosion in the United States.
