Multilayer/bilayer tablets have been applied for the formulation of incompatible components for compound preparations, but more often they are used to modify drug release. The objective of this study was to explore the feasibility of developing, using a bilayer tablet strategy, an immediate- and extended-release formulation of amoxicillin. The formulation of each layer was optimized separately and the bilayer tablets were compressed at an immediate/extended layer weight ratio of 3:7. The release of the bilayer tablets was evaluated and it was found to be very similar to Moxatag®, an immediate- and extended-release formulation approved by FDA. The kinetic mechanism study showed that the release of the bilayer tablets correlated better with the Ritger–Peppas model (correlation coefficient R = 0.9963) and a non-Fickian drug release mechanism, and its release was principally driven by diffusion and secondarily by polymer erosion. The stress testing demonstrated that high temperature and humidity are potential risk factors affecting the quality of the bilayer tablets. In addition, the bilayer tablets showed a similar bioavailability to Moxatag® in beagle dogs. buy original levitra The objective of this randomized, double-blind, multicenter study of 329 adult patients requiring hospitalization was to compare the safety and efficacy of sparfloxacin at a dosage of 200 mg once daily (following a 400-mg loading dose on day 1) with those of amoxicillin given as a 1-g oral dose three times daily for treatment of community-acquired pneumonia suspected to be due to Success of treatment was determined by a combination of clinical assessment and chest radiography. Pneumococcal pneumonia was the confirmed diagnosis for 177 patients (54%). Overall rates of success among evaluable patients were equivalent between drugs, both at the end of treatment (sparfloxacin, 92%; amoxicillin, 87%) and at follow-up (sparfloxacin, 89%; amoxicillin, 84%). Sparfloxacin was well-tolerated and produced fewer gastrointestinal effects than amoxicillin. In conclusion, sparfloxacin is a safe and effective alternative to high-dose amoxicillin for the treatment of suspected pneumococcal community-acquired pneumonia. Can i buy viagra in cabo san lucas Cipro ear infection Is once-daily amoxicillin as effective as twice-daily amoxicillin for treatment of GABHS pharyngitis? cheap authentic viagra We read with interest the once-daily amoxicillin versus twice-daily penicillin V in group A b-haemolytic streptococcal pharyngitis recently issued by the Archives. The American Heart Association recently recommended once-daily amoxicillin dosing when treating GABHS, and amoxicillin has been proven to be effective. An orally administered antimicrobial regimen for the treatment of group A β-hemolytic streptococcal (GABHS) pharyngitis given once rather than multiple times each day would be more convenient and might result in improved patient compliance. The purpose of this study was to evaluate the effectiveness of once-daily amoxicillin in the treatment of GABHS pharyngitis. Patients were randomly assigned to receive orally either amoxicillin (750 mg once daily) or penicillin V (250 mg three times a day) for 10 days. Compliance was monitored by urine antimicrobial activity. Outcomes were measured by impact on the clinical course, eradication of GABHS within 18 to 24 hours, and bacteriologic treatment failure rate as determined by follow-up throat cultures 4 to 6 and 14 to 21 days after completing therapy. GABHS isolates were serotyped to distinguish bacteriologic treatment failures (same serotype as initial throat culture) from new acquisitions (different serotypes). During the 16 months of this study, 152 children between 4 and 18 years of age (mean, 9.9 years) were enrolled; 79 children were randomly assigned to receive once-daily amoxicillin and 73 were assigned to receive penicillin V three times a day. The children in the two treatment groups were comparable with respect to age, duration of illness before initiation of therapy, compliance, and signs and symptoms at presentation. There was no significant difference in the clinical or bacteriologic responses of the patients in the two treatment groups at the 18- to 24-hour follow-up visit. Bacteriologic treatment failures occurred in 4 (5%) of the 79 patients in the amoxicillin group and in 8 (11%) of the 73 patients in the penicillin V group. These data demonstrate that once-daily amoxicillin therapy is as effective as penicillin V therapy given three times a day for the treatment of GABHS pharyngitis, and if confirmed by additional investigations, once-daily amoxicillin therapy could become an alternative regimen for the treatment of this disease. A once-daily antibiotic regimen for group A β-hemolytic streptococcal pharyngitis (GABHS) could improve compliance and be effective in the prevention of rheumatic fever, a dangerous complication of untreated or poorly treated GABHS. Amoxicillin is ideal for once-daily dosing due to its low cost. Azithromycin, cefadroxil, ceftibuten, cefixime and extended release amoxicillin are also FDA approved to treat GABHS once daily; however, even when taken for short courses, these antibiotics are more… Amoxicillin once daily Amoxicillin - Wikipedia, Once-daily amoxicillin versus twice-daily penicillin V in group A β.
