Antibiotics may be defined as the sub-group of anti-infective that are derived from bacterial sources and are used to treat bacterial infections.
An antibiotic may be classified basically as "narrow-spectrum" or "broad-spectrum" depending on the range of bacterial types that it affects. Narrow-spectrum antibiotics are active against a selected group of bacterial types. Broad-spectrum antibiotics are active against a wider number of bacterial types and, thus, may be used to treat a variety of infectious diseases.1
Narrow spectrum antibiotics are used for the specific infection when the causative organism is known.
- The narrow-spectrum antibiotic will not kill as many of the normal microorganisms in the body as the broad spectrum antibiotics. So, It has less ability to cause superinfection.
- The narrow spectrum antibiotic will cause less resistance of the bacteria as it will deal with only specific bacteria.
- Narrow spectrum antibiotics can be used only if the causative organism is identified.
- If you don't choose the drug very carefully, the drug may not actually kill the microorganism causing the infection.
Azithromycin is a azalide, a subclass of macrolide antibiotic.
Bacterial infections,those causing,
- middle ear infections,
- throat infections,
- Urinary tract infections
|Azithromycin||Dry Powder Suspension||100mg|
|Azithromycin||Tablets ||250mg, 500mg|
Clarithromycin is a macrolide antibiotic which works by interfearing with the protein synthesis of the bacteria.
- acute maxillary sinusitis,
- acute bacterial exacerbation of chronic bronchitis,
- skin structure infections
|Clarithromycin ||Tablets ||250mg, 500mg|
Clindamycin is lincosamine antibiotic.
Clindamycin has a bacteriostatic effect. It is a bacterial Protein synthesis inhibitor. It does so by binding preferentially to the 23S subunit of the bacterial 50s ribosome.
- Clindamycin is used primarily to treat infections caused by susceptible anaerobic bacteria, including infections of the respiratory tract, skin and soft tissue infections, and peritonitis
- In patients with hypersensitivity to penicillins, clindamycin may be used to treat infections caused by susceptible aerobic bacteria as well.
- It is also used to treat bone and joint infections, particularly those caused by Staphylococcus aureus.
|Clindamycin ||Injection||300mg/2ml, 600mg/4ml|
|Clindamycin + Benzoyl Peroxide||Gel||1% + 5%|
Erythromycin is a Macrolide antibiotic.
Erythromycin is a bactericidal.Erythromycin inhibit protein synthesis by binding to the 23S rRNA molecule (in the 50S subunit) of the bacterial ribosome blocking the exit of the growing peptide chain of sensitive microorganisms.
- Acute Bacterial Sinusitis,
- Acute Otitis Media Infection,
- Acute Streptococcal Pyogenes Bacterial Sinusitis,
- Acute Streptococcus Pneumoniae Bacterial Sinusitis,
- Bacterial Pneumonia,
- Chlamydia Cervicitis,
- Chlamydial Conjunctivitis,
- Chlamydia Trachomatis Urethritis,
- Diphtheria, Diphtheria Prevention,
- Mycoplasmal Pneumonia,
- Neonatal Pneumonia,
- Nongonococcal Urethritis,
- Pharyngitis due to Streptococcus Pyogenes,
- Pneumococcal Pharyngitis
- Skin Infections
|Erythromycin||Tablets||125mg, 250mg, 500mg|
Vancomycin is a glycopeptide antibiotic. Vancomycin is used for the treatment of infection caused by Gram-positive bacteria.
Vancomycin acts by inhibiting the bacterial cell wall synthesis.
- Pseudomembranous enterocolitis caused by C. difficile,
- Serious MRSA Infection,
- Enterococcal endocarditis,
- Penicillin resistant pneumococcal infections,
- Infections caused by diphtheroids.
|Vancomycin ||Lyophilised Injection||500mg, 1g|
|Active Ingrediant ||Form||Strength ||Pack Type||Packing Style|
Dry Powder Suspension
Clindamycin + Benzoyl Peroxide
125mg, 250mg, 500mg
