Antibiotics

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.

Trip has extensive coverage of the evidence base on antibiotics allowing users to easily find trusted answers. Coverage include guidelines, systematic reviews, controlled trials and evidence-based synopses.

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. Antibiotic prophylaxis may reduce the risk of pelvic infection, which is an important complication of this surgery, particularly in low-resource countries.We conducted a double-blind, placebo-controlled, randomized trial investigating whether antibiotic prophylaxis before surgery to complete a spontaneous (...) of these features and the clinically identified need to administer antibiotics. 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

Antibiotic treatment for newborns with congenital syphilis. Congenital syphilis continues to be a substantial public health problem in many parts of the world.

Systemic infection can be rapidly life-threatening in newborn babies, so those with risk factors are often treated pre-emptively with intravenous antibiotics. If sepsis is not confirmed by blood culture the decision whether to discontinue antibiotics needs to be made, but results of the blood culture takes time. Procalcitonin is released into the blood in response to inflammation, and low levels may give an earlier indication that there is no serious infection
