===Development of new drugs===
Since the discovery of antibiotics, [[research and development]] (R&D) efforts have provided new drugs in time to treat bacteria that became resistant to older antibiotics, but in the 2000s there has been concern that development has slowed enough that seriously ill people may run out of treatment options.<ref>{{cite journal | vauthors = Liu J, Bedell TA, West JG, Sorensen EJ | title = Design and Synthesis of Molecular Scaffolds with Anti-infective Activity | journal = Tetrahedron | volume = 72 | issue = 25 | pages = 3579–3592 | date = June 2016 | pmid = 27284210 | pmc = 4894353 | doi = 10.1016/j.tet.2016.01.044 }}</ref><ref>{{cite web |url= https://www.wp.dh.gov.uk/publications/files/2013/03/CMO-Annual-Report-Volume-2-20111.pdf |title=Annual Report of the Chief Medical Officer - Infections and the rise of antimicrobial resistance|date=2011|publisher=UK NHS|archive-url=https://web.archive.org/web/20131030190650/http://media.dh.gov.uk/network/357/files/2013/03/CMO-Annual-Report-Volume-2-20111.pdf|archive-date=30 October 2013|url-status=dead}}</ref> Another concern is that practitioners may become reluctant to perform routine surgeries because of the increased risk of harmful infection.<ref name="obama">{{cite news|url=https://www.npr.org/blogs/health/2013/06/04/188380562/obama-administration-seeks-to-loosen-antibiotic-approvals|title=Obama Administration Seeks To Ease Approvals For Antibiotics|newspaper=NPR.org|date=4 June 2013|publisher=NPR|access-date=7 August 2016|archive-url=https://web.archive.org/web/20150313042023/http://www.npr.org/blogs/health/2013/06/04/188380562/obama-administration-seeks-to-loosen-antibiotic-approvals|archive-date=13 March 2015|url-status=live}}</ref> Backup treatments can have serious side-effects; for example, antibiotics like [[aminoglycoside]]s (such as [[amikacin]], [[gentamicin]], [[kanamycin]], [[streptomycin]], etc.) used for the treatment of [[multi-drug-resistant tuberculosis|drug-resistant tuberculosis]] and cystic fibrosis can cause respiratory disorders, deafness and kidney failure.<ref>{{cite journal | vauthors = Prayle A, Watson A, Fortnum H, Smyth A | title = Side effects of aminoglycosides on the kidney, ear and balance in cystic fibrosis | journal = Thorax | volume = 65 | issue = 7 | pages = 654–658 | date = July 2010 | pmid = 20627927 | pmc = 2921289 | doi = 10.1136/thx.2009.131532 }}</ref><ref>{{cite journal | vauthors = Alene KA, Wangdi K, Colquhoun S, Chani K, Islam T, Rahevar K, Morishita F, Byrne A, Clark J, Viney K | display-authors = 6 | title = Tuberculosis related disability: a systematic review and meta-analysis | journal = BMC Medicine | volume = 19 | issue = 1 | pages = 203 | date = September 2021 | pmid = 34496845 | pmc = 8426113 | doi = 10.1186/s12916-021-02063-9 | doi-access = free }}</ref>.
