FRANKFURT (Reuters) - Swiss drugmaker Novartis raised its 2024 earnings guidance for the second time on Thursday, driven by a gain in prescriptions of drugs including heart failure treatment Entresto and Kesimpta for multiple sclerosis.

It said in a statement that full-year adjusted operating income is expected to grow by a "mid- to high teens" percentage, where it had previously seen a "low double-digit to mid-teens" percentage.
