Loratadine, an antihistamine, could include in its raw material seven impurities that ought to be separated identified and quantified for drug development and quality control. A HPLC method employing a SymmetryShield RP8 column has been developed and validated for loratadine and related compounds measurement, the last ones under the 0.1% level. The mobile phase consisted of methanol-buffer A (6...

BACKGROUND : Allergic rhinitis is a highly prevalent condition, particularly among children, whose schoolwork and quality of life may be impaired by its symptoms. METHODS : In this prospective, multicenter study, children between 6 and 12 years old with a diagnosis of severe perennial allergic rhinitis received a combination of the nonsedating antihistamine loratadine and the corticosteroid b...

Myopathy is a group of muscle diseases that can be induced or exacerbated by drug-drug interactions (DDIs). We sought to identify clinically important myopathic DDIs and elucidate their underlying mechanisms. Five DDIs were found to increase the risk of myopathy based on analysis of observational data from the Indiana Network of Patient Care. Loratadine interacted with simvastatin (relative ris...

A multicomponent pharmaceutical that contains loratadine, paracetamol, and pseudoephedrine was quantified using HPLC-PDA. The three analytes were well-separated in the dosage form on a C-18 column gradient mobile phase. quality by design strategy followed to achieve challenging separation. Screening optimization steps carried out investigate effect of many factors studied responses with minimum...

BACKGROUND The daily use of either intranasal corticosteroids or histamine(1) (H(1)) receptor antagonists has proved to be efficacious in the treatment of seasonal allergic rhinitis. Most patients, however, use these medications as needed. Our objective was to compare the effectiveness of as-needed use of H(1) receptor antagonists with that of intranasal corticosteroids in the treatment of seas...

Background: Lichen planus is a common dermatological condition. Many treatment options have been discussed in literature, each with its own risk profile. Betamethasone pulse therapy is one of the effective therapies mentioned.The objective of this study was to find out whether oral betamethasone mini pulse therapy is effective in lichen planus.Methods: A total of 40 pat...

Few randomized studies have compared the H1-receptor antagonists loratadine and ebastine in seasonal allergic rhinitis (SAR) patients. The objective of this study was to compare the efficacy and safety of ebastine 20 mg (E20), ebastine 10 mg (E10), loratadine 10 mg (L10), and placebo (P), once daily, in controlling symptoms of SAR over a 4-week period. This was a double-blind, placebo-controlle...

The conditions for identification were determined for four histamine antagonists: clemastine fumarate, loratadine, cetirizine dihydrochloride and desloratadine by TLC (thin-layer chromatography) method. The selected chromatographic conditions were used to develop a densitometric method for the content determination of the histamine antagonists in medicinal products and substances. The statistic...

This report describes ventricular tachycardia, likely to have been torsade de pointes, following ingestion of the non-sedating antihistamine loratadine. Documentation of the arrhythmia was made possible by the automatic electrogram storage facility of an implanted defibrillator in a patient with no prior history of cardiac arrhythmia.
