Abstract. Most guidelines for the management of hospitalized patients with community-acquired pneumonia (CAP) recommend commencing therapy with intravenous antibiotics, primarily because of concern about absorption of oral antibiotics in acutely ill patients. Clarithromycin Granules for Oral Suspension is indicated for treatment of infections in children due to susceptible organisms, in the following conditions: 1. Upper respiratory infections (e.g., streptococcal pharyngitis). 2. Lower respiratory infections (e.g., bronchitis, pneumonia). 3. Acute otitis media. 4.   Murray JJ, Solomon E, McCluskey D, et al.

  INR and prothrombin times should be frequently monitored while patients are receiving clarithromycin and oral anticoagulants concurrently. Long-term use may, as with other antibiotics, result in colonisation with increased numbers of non-susceptible bacteria and fungi. If superinfections occur, appropriate therapy should be instituted.

This study demonstrates that the extent of clarithromycin absorption is altered in patients who are acutely ill with CAP when compared to the same patients following their convalescence.

Clarithromycin may potentially be included in intravenous-to-oral conversion regimens, and a clarithromycin suspension may also have a potential role in the early transition to oral medications in patients unable to receive solid oral dosage forms.

However, clarithromycin has never been studied in seriously ill patients in this regard and it is unknown whether the absorption of clarithromycin is adequate in such patients. Objectives British Thoracic Society guidelines recommend clarithromycin in addition to beta-lactam antibiotics for patients with community-acquired pneumonia and CURB score 2–5.

Clarithromycin is a semi-synthetic macrolide antibiotic chemically related to erythromycin and azithromycin ().It is effective against a wide variety of bacteria, such as Haemophilus influenzae, Streptococcus pneumoniae, Mycoplasma pneumoniae, Staphylococcus aureus, and mycobacterium avium, and many all macrolide antibiotics, clarithromycin prevents bacteria from growing.

INTRODUCTION — Community-acquired pneumonia (CAP) is defined as an acute infection of the pulmonary parenchyma in a patient who has acquired the infection in the community, as distinguished from hospital-acquired (nosocomial) pneumonia (HAP).

CAP is a common and potentially serious illness [].It is associated with considerable morbidity and mortality, particularly in older adult patients. Clarithromycin is rapidly absorbed from the gastrointestinal tract after oral administration.

The absolute bioavailability of mg clarithromycin tablets was approximately 50%. For a single mg dose of clarithromycin, food slightly delays the onset of clarithromycin absorption, increasing the peak time from approximately 2 to hours.

Among the remaining patients, 49 died of sepsis: 24 (%) of 96 patients in the placebo group and 21 (%) of 90 patients in the clarithromycin group (P, by comparison of the groups). Time to death was significantly prolonged among patients treated with clarithromycin. In patients with penicillin allergy: clindamycin (Cleocin), cephalexin (Keflex), azithromycin (Zithromax), clarithromycin (Biaxin) Pneumonia Macrolide antibiotics, quinolone antibiotics.

Indication and trade names: as component of a combination ART for both naïve and pretreated HIV-infected patients. Of note, the lower dosage of 3TC which is approved for Hepatitis B is not recommended in HIV patients.

3TC is a component of the following: Epivir ® tablets, mg or mg 3TC. Epivir ® oral solution, 10 mg per ml 3TC. Patients were treated with clarithromycin or placebo for 14 days and observed for primary outcome events (e.g., all-cause mortality or non-fatal cardiac events) for several years.

1 A numerically higher number of primary outcome events in patients randomized to receive clarithromycin was observed with a hazard ratio of (95% confidence. Clarithromycin is an antibiotic prescription medicine approved by the U.S.

Food and Drug Administration (FDA) to treat certain bacterial infections—including community-acquired pneumonia, throat infections (pharyngitis), acute sinus infections, and others—that are caused by specific types of bacteria.

THE AMERICAN Thoracic Society in suggested that, in hospitalized patients with community-acquired pneumonia (CAP), the initial intravenous therapy may be switched to oral therapy (switch therapy) once the patient shows evidence of early clinical improvement.

1 Since then, several clinical trials have documented that performing switch therapy once the patient reaches clinical stability is. Clarithromycin mg/5 ml suspension is indicated in adults, adolescents and children, 6 months to 12 years, for the treatment of the following acute and chronic infections, when caused by clarithromycin susceptible organisms.
