CAIRO (Reuters) - Egypt's central bank said it is offering $120 million in its regular currency sale on Tuesday to be used for imports of pharmaceutical products, manufacturing components, vaccines and related chemicals and infant formula.

Egypt's economy has been hobbled by a shortage of foreign currency since a 2011 uprising drove away tourists and foreign investors. Dollars are rationed through weekly auctions imports of essential goods get priority.

The central bank, which has been keeping the pound artificially strong, devalued the currency on March 14 to 8.85 per dollar from 7.7301 and announced a more flexible exchange rate policy. It later strengthened the pound to 8.78 per dollar, where it has remained since.

A weaker currency has made it more expensive to import raw materials, and with the price of finished medicines fixed by the Health Ministry, some manufacturers have stopped making cheap generic medicines to staunch growing financial losses.

On Monday, Egypt raised the price cap on medicines that cost up to 30 Egyptian pounds ($3.38) by 20 percent in an effort to address drug shortages, the health minister said on Monday.
