Paser (Aminosalicylic Acid) - Summary

PASER SUMMARY

PASER granules are a delayed release granule preparation of aminosalicylic acid (p-aminosalicylic acid: 4-aminosalicylic acid) for use with other anti-tuberculosis drugs for the treatment of all forms of active tuberculosis due to susceptible strains of tubercle bacilli. The granules are designed for gradual release to avoid high peak levels not useful (and perhaps toxic) with bacteriostatic drugs. Aminosalicylic acid is rapidly degraded in acid media; the protective acid-resistant outer coating is rapidly dissolved in neutral media so a mildly acidic food such as orange, apple or tomato juice, yogurt or apple sauce should be used.

PASER is indicated for the treatment of tuberculosis in combination with other active agents. It is most commonly used in patients with Multi-drug Resistant TB (MDR-TB) or in situations when therapy with isoniazid and rifampin is not possible due to a combination of resistance and/or intolerance. When PASER is added to the treatment regimen in patients with proven or suspected drug resistance, it should be accompanied by at least one and preferably two other new agents to which the patient's organism is known or expected to be susceptible.

Photographers know the problem all too well: with the naked eye, you can see which branch a bird is sitting on, but spotting the bird in the blur of branches through the telephoto lens for high-magnification images requires considerable skill. It is a similar story for researchers who are looking to study proteins, the active biomolecules of cells. Olga Schubert, a doctoral student at ETH Zurich's Institute for Molecular Systems Biology, and her colleagues have now come up with a search aid...

Antibiotic resistance is a global problem. The World Health Organisation (WHO) estimates that for tuberculosis alone multi-drug resistance accounts for more than 150,000 deaths each year. WHO warns of "a doomsday scenario of a world without antibiotics," in which antibiotic resistance will turn common infections into incurable killers and make routine surgeries a high-risk gamble...

Published Studies Related to Paser (Aminosalicylic Acid)

Impact of a tailored patient preference intervention in adherence to 5-aminosalicylic acid medication in ulcerative colitis: results from an exploratory randomized controlled trial. [2011.09]
BACKGROUND: Up to 40% of patients with ulcerative colitis (UC) fail to comply with 5-aminosalicylic acid (5-ASA) therapy. This study aimed to evaluate multifaceted adherence-enhancing interventions for oral 5-ASA therapy in UC and consider changes in health beliefs and satisfaction with information... CONCLUSIONS: The multifaceted approach studied has potential for implementation in routine care for enhancing persistence with 5-ASA and thus improving patient outcomes.

Development of a Web-based concept for patients with ulcerative colitis and 5-aminosalicylic acid treatment. [2010.06]
BACKGROUND: Ulcerative colitis (UC) is a lifelong disease with increasing incidence. UC requires frequent outpatient clinic visits and continuous medical treatment. Web-based self-management in other chronic diseases influences disease course, and increases self-adherence, compliance and quality of life (QoL). Lack of easy access to inflammatory bowel disease clinics and patient education, their understanding of the importance of early treatment at relapse, poor compliance and self-adherence can be partly solved by a newly developed Web-based concept. AIMS: To describe the development and validation of the Web-based 'Constant-Care' concept... CONCLUSION: Patient education and training through a Web-based program (www.constant-care.dk) seems to be a feasible concept for increasing patients' ability to self-initiate treatment and increase the level of disease-specific knowledge. Relevant adjustment of the concept was implemented. The final outcome of the 'Constant-Care' concept is pending.

Effect of weekend 5-aminosalicylic acid (mesalazine) enema as maintenance therapy for ulcerative colitis: results from a randomized controlled study. [2007.09]
BACKGROUND: 5-aminosalicylic acid (5-ASA) is known to be effective in the treatment of active ulcerative colitis (UC). The aim of the current study was to investigate the effect of 5-ASA enemas, as a maintenance therapy for UC, when administered twice weekly as a weekend treatment regimen, compared to daily oral 5-ASA alone. We hypothesized that the weekend enema therapy would be better tolerated by patients who worked or attended school... CONCLUSIONS: This study demonstrated the beneficial effects of adding weekend 1 g 5-ASA enema to daily 3 g oral 5-ASA as maintenance therapy for UC.
