Antibiotics also referred to as antibacterial are a type of medicine that prevents the growth of bacteria. As such they are used to treat infections caused by bacteria. They kill or prevents bacteria from spreading.
Antibiotics are vital in modern day medicine; they are among the most frequently prescribed drug. There are over a 100 types of antibiotics, the main types and most commonly prescribed are penicillin, cephalosporin, macrolides, fluoroquinolone and tetracycline. They tend to be classified by mechanism of action. So, those that target the bacterial cell wall (penicillins and cephalosporins) or the cell membrane (polymyxins), or interfere with essential bacterial enzymes (rifamycins, lipiarmycins, quinolones, and sulfonamides) have bactericidal activities. Antibiotics such as macrolides, lincosamides and tetracyclines inhibit protein synthesis.
Antibiotics can all be defined by their specificity. “Narrow-spectrum” antibiotics target specific types of bacteria, for instance gram-negative (-ve) or gram-positive (+ve), whereas broad-spectrum antibiotics affect a wide range of bacteria.
Antibiotics are increasingly suffering from antibiotic resistance caused by bacterial mutations meaning the bacteria evolves to not be sensitive to the specific antibiotics being used.
Clinical trials are important to the development and understanding of antibiotics and their side effects. Although they are deemed safe, over use of the drug can kill good bacteria and lead to antibiotic resistance. This halts the ability of bacteria and microorganisms to resist the effects of the antibiotic. Clinical trials and research allow scientists and medical professionals to study the effects and develop new antibiotics.
Guideline-Based Clinical Assessment Versus Procalcitonin-Guided Antibiotic Use in Pneumonia: A Pragmatic Randomized Trial Efforts to reduce unnecessary and unnecessarily long antibiotic treatment for community-acquired pneumonia have been attempted through use of procalcitonin and through guidelines based on serial clinical assessment. Our aim is to compare guideline-based clinical assessment- and procalcitonin algorithm-guided antibiotic use among patients with community-acquired pneumonia.We (...) performed a pragmatic, randomized, multicenter trial from November 2012 to April 2015 at 12 French hospitals. We included emergency department (ED) patients older than 18 years with community-acquired pneumonia. Patients were randomly assigned to either the procalcitonin-guided or clinical assessment group. In accordance with past studies, we hypothesized that serial clinical assessment would be superior to procalcitonin-guided care. The primary outcome was antibiotic duration, and secondary outcomes

Infections that cannot be treated continue to develop. The rapid spread of multidrug resistant organisms means that we may not be able to treat everyday infections or diseases with antibiotics (...) in the near future. Many existing antimicrobials are becoming less effective as bacteria, viruses, protozoa and fungi are adapting and becoming resistant to medicines. Inappropriate use of these valuable medicines has also added to the problem.

Antibiotic use for irreversible pulpitis. Irreversible pulpitis, which is characterised by acute and intense pain, is one of the most frequent reasons that patients attend for emergency dental care. Apart from removal of the tooth, the customary way of relieving the pain of irreversible pulpitis is by drilling into the tooth, removing the inflamed pulp (nerve) and cleaning the root canal. However, a significant number of dentists continue to prescribe antibiotics to stop the pain (...) of irreversible pulpitis.This review updates the previous version published in 2016.To assess the effects of systemic antibiotics for irreversible pulpitis.We searched Cochrane Oral Health's Trials Register (to 18 February 2019); the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 1) in the Cochrane Library (searched 18 February 2019); MEDLINE Ovid (1946 to 18 February 2019); Embase Ovid (1980 to 18 February 2019); US National Institutes of Health Ongoing Trials Register
Antibiotic therapy for adults with neurosyphilis. Neurosyphilis is an infection of the central nervous system, caused by Treponema pallidum, a spirochete capable of infecting almost any organ or tissue in the body causing neurological complications due to the infection. This disease is a tertiary manifestation of syphilis. The first-line treatment for neurosyphilis is aqueous crystalline penicillin. However, in cases such as penicillin allergy, other regimes of antibiotic therapy can be used.To (...) assess the clinical effectiveness and safety of antibiotic therapy for adults with neurosyphilis.We searched the Cochrane Library, CENTRAL, MEDLINE, Embase, LILACS, World Health Organization International Clinical Trials Registry Platform and Opengrey up to April 2019. We also searched proceedings of eight congresses to a maximum of 10 years, and we contacted trial authors for additional information.We included randomised clinical trials that included men and women, regardless of age, with definitive

Two weeks versus four weeks of antibiotic therapy after surgical drainage for native joint bacterial arthritis: a prospective, randomised, non-inferiority trial The optimal duration of postsurgical antibiotic therapy for adult native joint bacterial arthritis remains unknown.We conducted a prospective, unblinded, randomised, non-inferiority study comparing either 2 or 4 weeks of antibiotic therapy after surgical drainage of native joint bacterial arthritis in adults. Excluded were implant (...) -related infections, episodes without surgical lavage and episodes with a follow-up of less than 2 months.We enrolled 154 cases: 77 in the 4-week arm and 77 in the 2-week arm. Median length of intravenous antibiotic treatment was 1 and 2 days, respectively. The median number of surgical lavages was 1 in both arms. Recurrence of infection was noted in three patients (2%): 1 in the 2-week arm (99% cure rate) and 2 in the 4-week arm (97% cure rate). There was no difference in the number of adverse events

Health Technology Assessment (HTA) of CRP POCT Health Information and Quality Authority iv Foreword Antimicrobial resistance occurs when bacteria adapt in response to the use of medicines. When bacteria become antibiotic resistant, infections become more difficult to manage and treat. Antimicrobial resistance is a significant threat to public health, and widely acknowledged to be associated with the excessive (...) , but not for those with acute bronchitis. ? Overprescribing of antibiotics for RTIs in primary care is common in most industrialised countries, with high levels of inappropriate prescribing documented. Antibiotic treatment of RTIs can expose patients to an increased risk of an adverse event, with one out of five patients experiencing mostly minor and self-limiting adverse events. Antimicrobial resistance (AMR) is a growing and significant threat to public health, and it is widely recognised that antibiotic

Antibacterial Envelope to Prevent Cardiac Implantable Device Infection. Infections after placement of cardiac implantable electronic devices (CIEDs) are associated with substantial morbidity and mortality. There is limited evidence on prophylactic strategies, other than the use of preoperative antibiotics, to prevent such infections.We conducted a randomized, controlled clinical trial to assess the safety and efficacy of an absorbable, antibiotic-eluting envelope in reducing the incidence (...) of infection associated with CIED implantations. Patients who were undergoing a CIED pocket revision, generator replacement, or system upgrade or an initial implantation of a cardiac resynchronization therapy defibrillator were randomly assigned, in a 1:1 ratio, to receive the envelope or not. Standard-of-care strategies to prevent infection were used in all patients. The primary end point was infection resulting in system extraction or revision, long-term antibiotic therapy with infection recurrence
A Randomized Trial of Prophylactic Antibiotics for Miscarriage Surgery. Surgical intervention is needed in some cases of spontaneous abortion to remove retained products of conception.

The definition of pelvic infection was changed before the unblinding of the data; the original strict definition was two or more of the clinical features, without reference to the administration of antibiotics.We enrolled 3412 patients in Malawi, Pakistan, Tanzania, and Uganda. A total of 1705 patients were assigned to receive antibiotics and 1707 to receive placebo. The risk of pelvic infection was 4.1% (68 of 1676 pregnancies
