Switzerland-based Alliance Boots, which owns the Boots and Boots Opticians brands in the UK, saw overall sales surge by 10.6% to £23.3bn, driven by a 23.6% increase in sales at its pharmaceutical wholesale division.
Pre-tax profits for the group increased by 38% to £673m.
Stefano Pessina, executive chairman of Alliance Boots, said: "Alliance Boots continues to perform strongly, delivering a double digit growth in trading profit through a combination of organic growth and acquisitions, while at the same time reducing net borrowings.
"Looking to the year ahead, we are planning for consumer demand to be subdued and expect governments to continue to seek ways to contain growth in healthcare expenditure. In spite of this, we are confident about our future prospects both in the short and longer term.
