The most frequent adverse drug reaction was diarrhea (1.30%) that resolved or subsided during treatment or after discontinuation or completion of therapy in all cases. Data from the clinical studies carried out with cefditoren in the treatment of pharyngotonsillitis from 2007 to 2010 in Japan showed that the percentage of adverse events was very low and diarrhea was the most frequent event. In the largest study (734 children), the incidence of adverse reactions was 1.50% (11 events in 11 patients), with 3 events of diarrhea and three of hematuria in urinalysis without clinical symptoms. In a study carried out in children in Thailand comparing cefditoren (66 patients) with amoxicillin/clavulanic acid (72 patients) for 10 days in the treatment of acute bacterial rhinosinusitis, the most frequent adverse event was diarrhea, with significant (P = 0.02) differences in the percentages found for both compounds (4.5% with cefditoren vs. 18.1% for amoxicillin/clavulanic acid). Guidelines
Japanese Guidelines
Japanese guidelines for the management of respiratory infectious diseases in children recommend cefditoren pivoxil as an initial antimicrobial therapy in children (2 months and older). A panel of 70 pulmonologists, coordinated by 9 experts in respiratory care recommendations
A consensus on appropriate prescribing in lower respiratory tract infection therapy was appraised by Delphi exercise, based on a panel of 70 pulmonologists, coordinated by a scientific committee of nine experts in respiratory medical care. Amongst 3rd-generation oral cephalosporins, cefditoren pivoxil has the highest intrinsic activity against Streptococcus pneumoniae, penicillin-resistant strains included.
Montelukast, sold under the brand name Singulair among others, is a medication used in the maintenance treatment of asthma. It is generally less preferred for this use than inhaled corticosteroids. It is not useful for acute asthma attacks. Other uses include allergic rhinitis and hives of long duration. For allergic rhinitis it is a second-line treatment.Common side effects include abdominal pain, cough, and headache. Severe side effects may include allergic reactions, such as anaphylaxis and eosinophilia. Use in pregnancy appears to be safe. Montelukast is in the leukotriene receptor antagonist family of medications. It works by blocking the action of leukotriene D4 in the lungs resulting in decreased inflammation and relaxation of smooth muscle.Montelukast was approved for medical use in the United States in 1998. It is available as a generic medication. In 2020, it was the fourteenth most commonly prescribed medication in the United States, with more than 31 million prescriptions. Medical uses
Montelukast is used for a number of conditions including asthma, exercise induced bronchospasm, allergic rhinitis, and urticaria. It is mainly used as a complementary therapy in adults in addition to inhaled corticosteroids, if inhaled steroids alone do not bring the desired effect. It is also used to prevent allergic reactions and asthma flare-ups during the administration of intravenous immunoglobulin. It may also be used as an adjunct therapy in symptomatic treatment of mastocytosis. It is taken by mouth, as a tablet, chewable tablet, or as granules.
