Market Growth Factors

The global rise in infectious diseases is the main factor that drives the growing market of antibiotics. The diseases include pneumonia, tuberculosis, urinary tract infections, and gastrointestinal infections that give rise to a heavy burden especially in poorly sanitized areas. According to the report, urinary tract infections affect 10 out of 25 women and 3 out of 25 men at some point, hence requiring stronger antibiotics. With the increased occurrence of such infections, the requirement of the effective antibiotics that can cover wide bacterial strains is also rising considerably and hence, making a big part of the market growth.

Rising antimicrobial resistance (AMR) is a dual-edge sword for the market- it is both a serious challenge and a driver. It was reported that in 2019, AMR caused directly 1.27 million deaths all over the world. The incorrect and excessive use of antibiotics has hastened the rise of drug-resistant strains like MRSA and CRE. This resistance makes the traditional antibiotics less effective, and hence the urgent need for new antibiotics and antimicrobial diagnostics arises, along with the corresponding increase of their sales. Governments and public health organizations around the world have enacted antibiotic stewardship as one of their main strategies to counteract these difficulties; and this has created a favorable environment for research and innovation investments in the antibiotics market.

The antibiotic development pipeline keeps getting stronger due to the technological breakthrough in biotechnology, genomics, and drug discovery techniques. The companies are taking advantage of computer-aided drug design, high-throughput screening, and rapid diagnostic technology to maximize the antibiotics potency, cutting down the time taken and the money spent in the development stage. Pfizer's $120 million funding in the clinical-stage biotech companies is a clear illustration of how the industry is dedicated to innovation. Such breakthroughs allow the entry of new antibiotics which can tackle resistant pathogens and also improve the health of patients through personalized treatments.
