Bengaluru-based Medlife International, which operates an online pharmacy, has raised $15 million via non-convertible debentures from Mauritius-based Wilson Global Opportunities Fund. The company will use the capital for its working capital requirements, repaying existing loans and business development, according to its latest regulatory filings. It will pay an interest of 14% a year and repay the entire debt in 48 months over four equal installments. The company has also created a security interest on its current and moveable assets and on those of Medlife Wellness Retail.
