    Ciprofloxacin spectrum


    If you're reading this article, you may have been prescribed ciprofloxacin (Cipro), levofloxacin (Levaquin) or some other type of fluoroquinolone for the treatment of a bacterial infection (think respiratory or urinary tract infection). Overall, these drugs are safe and effective against a wide array of gram-positive and gram-negative bacterial pathogens making them a good choice for systemic or body-wide treatment. At the core of all fluoroquinolones—including drugs like ciprofloxacin and levofloxacin—are 2 six-member carbon rings attached to a fluoride atom. These drugs work by targeting 2 bacterial enzymes responsible for notching, coiling, and sealing DNA during replication: DNA gyrase and topoisomerase IV. Because current fluoroquinolones bind to 2 separate enzymes, it's harder for bacteria to mutate and to evade the actions of these drugs. In addition to broad-spectrum bacterial coverage, fluoroquinolones also sport other properties that make them great antibiotics. First, they are taken by mouth (and not by injection). Its empirical formula is C17H18FN3O3 and MW is 331.3. The chemical structure is: Ciprofloxacin inhibits the enzyme bacterial DNA gyrase and prevents replication of bacterial DNA during bacterial growth and reproduction. Ciprofloxacin is well absorbed after oral administration. Blood concentrations of intravenously administered drug are similar to those of orally administered drug. Ciprofloxacin is active against many gram-positive bacteria and gram-negative bacteria. Ciprofloxacin has rapidly bactericidal activity and high potency. Protective intestinal streptococci and anaerobes are spared. Dose modification is needed in patients of renal impairment. Caution in paediatric, geriatric, pregnant and nursing patients.

    Ciprofloxacin is a broad-spectrum fluoroquinolone antibiotic used in the treatment of a wide range of mild to moderate gram-positive & gram-negative infections. Although extensive information is available on the safety profile of ciprofloxacin in adults, few published data exist regarding the tolerability & toxicity of this drug in patients. Ciprofloxacin is a potent inhibitor of CYP1A2, CYP2D6, and CYP3A4. Mechanism of action. Ciprofloxacin is a broad-spectrum antibiotic of the fluoroquinolone class. It is active against both Gram-positive and Gram-negative bacteria. Ciprofloxacin hydrochloride, 1-cyclopropyl-6- fluoro-1,4-dihydro-4-oxo-7-1-piperazinyl-3- quinoline carboxilic acid CPX, is a broad spectrum fluoroquinolone antibacterial agent used in the treatment of various bacterial infections caused by gram-positive and gram-negative microorganisms1,2 fig. 1.

    The newer fluoroquinolones have broad-spectrum bactericidal activity, excellent oral bioavailability, good tissue penetration and favorable safety and tolerability profiles. A new four-generation classification of the quinolone drugs takes into account the expanded antimicrobial spectrum of the more recently introduced fluoroquinolones and their clinical indications. First-generation drugs (e.g., nalidixic acid) achieve minimal serum levels. Second-generation quinolones (e.g., ciprofloxacin) have increased gram-negative and systemic activity. Third-generation drugs (e.g., levofloxacin) have expanded activity against gram-positive bacteria and atypical pathogens. Fourth-generation quinolone drugs (currently only trovafloxacin) add significant activity against anaerobes. The quinolones can be differentiated within classes based on their pharmacokinetic properties. Antibiotics A broad-spectrum–GNRs, staphylococci, fluoroquinolone with limited activity against streptococci, anaerobes Indications Acute sinusitis, acute exacerbation of chronic bronchitis, UTI, acute cystitis in ♀, bacterial prostatitis, intra-abdominal infection, skin, bone and joint infection, infectious diarrhea, typhoid fever, gonorrhea Adverse effects GI pain, N&V, diarrhea, seizures, rash, photosensitivity. A fluoroquinolone antibiotic used to treat urinary infections and, as eye drops, for the treatment of corneal ulcers. Mutations lead to an alteration in the structure of this enzyme leading to antibiotic resistance. A substance derived from a mould or bacterium, or produced synthetically, that destroys (bactericidal) or inhibits the growth (bacteriostatic) of other microorganisms and is thus used to treat infections. Current research suggests the possibility of preventing this process. Some substances have a narrow spectrum of activity whereas others act against a wide range of both gram-positive and gram-negative organisms (broad-spectrum antibiotics). (2) Drugs affecting the bacterial cytoplasmic membrane, such as polymyxin B sulfate and gramicidin. Antibiotics can be classified into several groups according to their mode of action on or within bacteria: (1) Drugs inhibiting bacterial cell wall synthesis, such as bacitracin, vancomycin and the β-lactams based agents (e.g. (3) Drugs inhibiting bacterial protein synthesis, such as aminoglycosides (e.g. amikacin sulfate, framycetin sulfate, gentamicin, neomycin sulfate and tobramycin), tetracyclines, macrolides (e.g. erythromycin and azithromycin) and chloramphenicol. (4) Drugs inhibiting the intermediate metabolism of bacteria, such as sulfonamides (e.g. (5) Drugs inhibiting bacterial DNA synthesis, such as nalixidic acid and fluoroquinolones (e.g. See antiinflammatory drug; fusidic acid.n brand name: Cipro; drug class: fluoroquinolone antiinfective; action: a broad-spectrum bactericidal agent that inhibits enzyme deoxyribonucleic acid (DNA) gyrase needed for replication of DNA; uses: adult urinary tract infection, uncomplicated gonorrhea, typhoid fever; effective against some periodontal organisms. ciprofloxacin, levofloxacin, moxifloxacin, norfloxacin and ofloxacin). (6) Other antibiotics such as fusidic acid, the diamidines, such as propamidine isethionate and dibrompropamidine.

    Intravenous salbutamol can be used as a tocolytic to relax the uterine smooth muscle to delay premature labor. While preferred over agents such as atosiban and ritodrine, its role has largely been replaced by the calcium channel blocker nifedipine, which is more effective, better tolerated, and administered orally. Rarely occurring, but of importance, are allergic reactions of paradoxical bronchospasms, urticaria (hives), angioedema, hypotension, and collapse. High doses or prolonged use may cause hypokalemia, which is of concern especially in patients with renal failure and those on certain diuretics and xanthine derivatives. which are the predominant receptors on the bronchial smooth muscles. Activation of these receptors causes adenylyl cyclase to convert ATP to c AMP, beginning the signalling cascade that ends with the inhibition of myosin phosphorylation and lowering the intracellular concentration of calcium ions (myosin phosphorylation and calcium ions are necessary for muscle contractions). The increase in c AMP also inhibits inflammatory cells in the airway, such as basophils, eosinophils, and most especially mast cells, from releasing inflammatory mediators and cytokines. The (R)-(−)-enantiomer (CIP nomenclature) is shown in the image at right (top), and is responsible for the pharmacologic activity; the (S)-( )-enantiomer (bottom) blocks metabolic pathways associated with elimination of itself and of the pharmacologically active enantiomer (R).

    Sertraline belongs to a class of medications known as selective serotonin reuptake inhibitors (SSRIs). It is used to treat depression, panic disorder, and obsessive-compulsive disorder (OCD). Sertraline works by affecting the balance of chemicals in the brain. Specifically, it increases the level of a neurotransmitter called serotonin in the brain. Increased serotonin levels can help improve mood, reduce panic attacks, and treat OCD. Although improvements may occur earlier, the full response to the medication may not appear until after 4 weeks of treatment or longer. This medication may be available under multiple brand names and/or in several different forms.
