What is ciprofloxacin?

Use of Ciprofloxacin

Ciprofloxacin is mainly used for the treatment of bacterial infection.
Ciprofloxacin belongs form quinolone antibiotic .for the gram-negative bacilli is more
Ciprofloxacin is more active .where Gram-positive bacteria are required more concentration for inhibition.
Ciprofloxacin is used to tried for major infection and also use for a treat some difficult treatment process . Ciprofloxacin has Bactericidal activity, oral efficacy and good tolerability Ciprofloxacin is not use for minor cases or gram-positive or anaerobes are mainly caused the Infection.
If the patient is not taking the drug directly then use of intravenous injection and after some modifiy, you can use an oral dose.
Ciprofloxacin is for other diseases by a bacterial infection are
         1.    Urinary tract infection (UTI)  

       Ciprofloxacin is use for UTI treatment is highly cure rate 
    2.    Gonorrhoe

    3.    Chancroid

    4.    Bacterial gastroenteritis

    5.    Typhoid

      Ciprofloxacin is almost given the patient who is suffer the typhoid.
      In India 95% S.typhi is Isolated which is sensitive to ciprofloxacin.
6                Ciprofloxacin is also use for the tritment of Bone ,soft tissue ,gynaecological and                    wound infection. Caused by resistance staph .and gram neagative bacteria.
                 6Respiratory infection

8              7. Tuberculosis

      Ciprofloxacin is use for the treatment Tuberculosis with a combination of another drug.
9              8.Gram –negative septicaemias
      Parenteral ciprofloxacin might be combined with cephalosporin and an  aminoglycoside.
                9. Meningiti

       Though penetration is CSF is not very good, ciprofloxacin has been successfully using for the Gram-negative bacteria.
1            10. Prophylaxis

            Infection in neutropenic and cancer and other susceptible patients.
1            11. Conjunctivitis

Mechanism of Action Ciprofloxacin

Ciprofloxacin is first generation drug of fluoroquinolones .
Ciprofloxacin is florinated analauge  that means it contain fluorine .
Ciprofloxacin has the capacity of deep panitration to tissue so it called broad spectrum antibiotic it kills gram positive bacteria , gram negative  and intracellular organism 
Before I explain how it is act on bacteria first I explain how bacteria replicate.

Bacteria DNA is circular double strand DNA when it replicate by process name is transcription and translation.


In the transcription process DNA are open for replication of MRNA.
Due to opening of DNA side are positive super coli at the of DNA.
In this situation Enzyme like DNA gyrase is helps to opening of Positive supercoil so replication done successfully.

How ciprofloxacin act on the bacteria

Ciprofloxacin is act on the DNA gyrase .
DNA gyrase is other wise called topo isomerase.
DNA gyrase consists of Two A and Two B subunit . Two A subunit help to cutting of positive supercoil and untwisted DNA .and TWO B subunit help to reconnect the DNA .
Ciprofloxacin is attached With TWO B subunit and stop the action of TWO B subunit .
Enzyme is only change the configuration of of DNA.   
So there are cutting process is continued so DNA is collapced.
Finally bacteria is dead.

Resistance of Ciprofloxacin

Due to unique mechanism of action Plasmid mediated Transferable resistance probably does not occour. As compare to other antibiotic .
Some bacteria are increasing his resistance like Salmonella, Pseudomonas, staphylococci, gonococci and pneumococci.
Ciprofloxacin is well absorption through GI Tract. Its oral bioavailability is about
About 60-80%, and plasma protein binding is 20-35 %.
volume of distribution in liter/Kg is 3-4, precent metabolized is 20.
Plasma half life or t1/2 is 3-5 hr ,
Ciprofloxacin is avalible in both oral and intravenous Injection.

Dose of ciprofloxacin

Normally ciprofloxacin oral dose is present from 250 mg to 750 mg .
And intravenous injection 100 mg to 200 mg .
For Gonorrhoea  500 mg dose is cure the disease,
For chancroid  500 mg BD for 3 days for  cure of dease.
For typhoid 500 mg to 750 mg BD for 10 days , if patient unable to take drug orally may treated with 200 mg iV injection for 12 hourly 
Interaction of ciprofloxacin

Plasma concentration of theophylline , caffeine and warfarin are increased by take of ciprofloxacin. Due to inhibition of metabolism .
NSAIDs may enhance the CNS toxicity of Floroquinolone.
Antacids, sucralfate and iron salts given reduce absorption of ciprofloxacin.

Some Brand name of Ciprofloxacin

These all the drug are avalibable in the market as 250 mg , 500 mg ,750 mg as tablets and 200 mg and 100 ml iv injection and 3 mg /ml as eye drops.

Similar drug like ciprofloxacin

Norfloxacin and Ofloxacin are similar to drug like ciprofloxacin.
But ciprofloxacin is well drug between all thise three drug.

Histroy of Ciprofloxacin

As we discuss avobe all know ciprofloxacin is Floroquinolones derivative .
The  first generation of fluroquinolones  is discovered in 1980s and its one Fluoro substitution . in 1990s Compounds have been developed with additional fluoro and other substitution for more effective against the bacteria.
