Fluoroquinolones are one of the most commonly prescribed antibiotic classes in the United States despite their association with adverse consequences, including Clostridium difficile infection (CDI). We sought to evaluate the impact of a healthcare-system antimicrobial stewardship-initiated respiratory fluoroquinolone restriction program on utilization, appropriateness of quinolone-based therapy based on institutional guidelines, and CDI rates. Following implementation, respiratory fluoroquinolone utilization decreased from a monthly mean (SD) of 41...

Antimicrobial drugs used in clinical practice are selected on the basis of their selective toxicity against bacterial cells. However, all exhibit multiple offsite interactions with eukaryotic cell structures, resulting in adverse reactions during antimicrobial pharmacotherapy. A multitude of these side effects involve the nervous system as antimicrobials at clinically relevant concentrations seem to interact with many of the same molecules usually implicated in the action of psychotropic drugs. The importance of such events cannot be overstated, as the misdiagnosis of an adverse drug reaction as a symptom of a primary psychiatric or neurological disorder entails great suffering for the patient affected as well as significant costs for the healthcare system...

The current frontline symptomatic treatment for Alzheimer's disease (AD) is whole-body upregulation of cholinergic transmission via inhibition of acetylcholinesterase. This approach leads to profound dose-related adverse effects. An alternative strategy is to selectively target muscarinic acetylcholine receptors, particularly the M1 muscarinic acetylcholine receptor (M1 mAChR), which was previously shown to have procognitive activity. However, developing M1 mAChR-selective orthosteric ligands has proven challenging...

Third generation quinolones are extensively used to treat a variety of common bacterial infections. Due to their extensive use in clinical practice, an increase in neuropsychiatric events has been reported. We report the case of psychotic symptoms occurs after three doses of moxifloxacin in a healthy adult male with no underlying risk factors. After the discontinuation of moxifloxacin treatment, there was a complete resolution of patient's symptoms. The case draws attention to a rare side effect of a commonly use drug and alert the clinicians to be cautious in those patients that have a baseline risk factors which makes the patient more susceptible to such adverse drug effect...

Travelers' diarrhea (TD) is one of the most important global health issues among international travelers, especially those traveling to developing countries. Enterotoxigenic Escherichia coli (ETEC) is the most frequently isolated pathogen causing TD. Although TD is self-limiting, it is also severely incapacitating. Ciprofloxacin is one of the standard quinolone antibiotics used in patients with TD. However, the alarming levels of antibiotic resistance have necessitated the urgent need to identify new drugs...

Antibiotics are the one of the most commonly used group, of drugs, in general medical and surgical practice. The quinolone antibiotics can lead to a range of adverse neuropsychiatric effects with most of the reports due to ciprofloxacin and ofloxacin. Here, we report an interesting and rarely described psychiatric manifestation of recurrent mania following the use of quinolone antibiotics, and briefly review the available literature.

The identification of the antibacterial action of nalidixic acid (nx) was central to the development of the quinolone antibacterial compounds. The ability of the nx naphthyridyl ring to interact with and inhibit some proteins has encouraged the investigation of similar structures in the search for more active compounds with less adverse effects. The possibility of structural modification by attachment of other biologically active moieties to the naphthyridyl ring of nx allowed the development of new active antimicrobial molecules...

Human babesiosis is a tick-borne multisystem disease caused by Babesia species of the apicomplexan phylum. Most clinical cases and fatalities of babesiosis are caused by Babesia microti Current treatment for human babesiosis consists of two drug combinations, atovaquone + azithromycin or quinine + clindamycin. These treatments are associated with adverse side effects and a significant rate of drug failure. Here, we provide evidence for radical cure of experimental babesiosis in immunodeficient mice using a combination of an endochin-like quinolone (ELQ) prodrug and atovaquone...

The proarrhythmic effects of new drugs have been assessed by measuring rapidly activating delayed-rectifier K+ current (IKr) antagonist potency. However, recent data suggest that even drugs thought to be highly specific IKr blockers can be arrhythmogenic via a separate, time-dependent pathway such as late Na+ current augmentation. Here, we report a mechanism for a quinolone antibiotic, sparfloxacin-induced action potential duration (APD) prolongation that involves increase in late L-type Ca2+ current (ICaL) caused by a decrease in Ca2+-dependent inactivation (CDI)...

Fluoroquinolones are highly effective antibiotics with many desirable pharmacokinetic and pharmacodynamic properties including high bioavailability, large volume of distribution, and a broad spectrum of antimicrobial activity. Despite their attractive profile as anti-infective agents, their use in children is limited, primarily due to safety concerns. In this review we highlight the pharmacological properties of fluoroquinolones and describe their current use in pediatrics. In addition, we provide a comprehensive assessment of the safety data associated with fluoroquinolone use in children...

OBJECTIVE: Changes in the microbiota (dysbiosis) were suggested to increase the risk of several psychiatric conditions through neurologic, metabolic, and immunologic pathways. Our aim was to assess whether exposure to specific antibiotic groups increases the risk for depression, anxiety, or psychosis. METHOD: We conducted 3 nested case-control studies during the years 1995-2013 using a large population-based medical record database from the United Kingdom. The study included 202,974 patients with depression, 14,570 with anxiety, and 2,690 with psychosis and 803,961, 57,862, and 10,644 matched controls, respectively...

BACKGROUND: Long-acting bronchodilators, comprising long-acting beta2-agonists (LABA) and long-acting anti-muscarinic agents (LAMA, principally tiotropium), are commonly used for managing persistent symptoms of chronic obstructive pulmonary disease (COPD). Combining these treatments, which have different mechanisms of action, may be more effective than the individual components. However, the benefits and risks of combining tiotropium and LABAs for the treatment of COPD are unclear. OBJECTIVES: To compare the relative effects on markers of quality of life, exacerbations, symptoms, lung function and serious adverse events in people with COPD randomised to LABA plus tiotropium versus tiotropium alone; or LABA plus tiotropium versus LABA alone...
