Compliance with treatment: related-issues and insights for pharmacist intervention

N.L. Silva; Eliane Ribeiro; João Navarro; Antonio Carlos Zanini

Polymorphism in solids is a common phenomenon in drugs, which can lead to compromised quality due to changes in their physicochemical properties, particularly solubility, and, therefore, reduce bioavailability. Herein, a bibliographic survey was performed based on key issues and studies related to polymorphism in active pharmaceutical ingredient (APIs) present in medications from the Farmacia Popular Rede Propria. Polymorphism must be controlled to prevent possible ineffective therapy and/or improper dosage. Few mandatory tests for the identification and control of polymorphism in medications are currently available, which can result in serious public health concerns.

Cost of severe asthma in Brazil—systematic review

Abstract Introduction: Severe asthma is characterized by frequent exacerbations, symptoms limiting daily activities and nocturnal symptoms. It requires the continuous use of medications, at high doses, and, sometimes, continuous use of oral corticosteroids, representing a significant burden to health system and society. This systematic review sought to address economic data related to severe asthma in Brazil. Method: In June 2014, electronic searches were conducted to identify relevant publications. Quality criteria were developed and applied to each selected study. In order to compare results across the selected studies, costs were refined to an annual basis, grouped according to the study perspective, inflated and converted to 2014 USD. Results: Cost analyses from the Brazilian public health system perspective were derived from two studies and showed an average annual hospital cost per patient of 135 USD and 733 USD, respectively. From the family perspective, average annual direct costs per patient varied from 764 USD to 929 USD. Conclusion: Hospitalizations and medications seem to be the most important resources funded by the Brazilian public health system and by patients and their families. Although further studies are necessary, as information on cost of this disease is scarce in Brazil, these findings suggest that there is a potential room for improving severe asthma care among Brazilian patients.

Cost effectiveness of omalizumab add-on to standard-of-care therapy in patients with uncontrolled severe allergic asthma in a Brazilian healthcare setting.

Abstract Objective: Omalizumab add-on to standard-of-care therapy has proven to be efficacious in severe asthma patients for whom exacerbations cannot be controlled otherwise. Moreover, evidence from different healthcare settings suggests reduced healthcare resource utilization with omalizumab. Based on these findings, this study aimed to assess the cost-effectiveness of the addition of omalizumab to standard-of-care therapy in patients with uncontrolled severe allergic asthma in a Brazilian healthcare setting. Methods: A previously published Markov model was adapted using Brazil-specific unit costs to compare the costs and outcomes of the addition of omalizumab to standard-of-care therapy vs standard-of-care therapy alone. Model inputs were largely based on the eXpeRience study. Costs and health outcomes were calculated for lifetime-years and were annually discounted at 5%. Both one-way and probabilistic sensitivity analyses were performed. Results: An additional cost of R

53,890. One-way sensitivity analysis indicated that discount rates, standard-of-care therapy exacerbation rates, and exacerbation-related mortality rates had the largest impact on incremental cost-effectiveness ratios. Limitations: Assumptions of lifetime treatment adherence and rate of future exacerbations, independent of previous events, might affect the findings. The lack of Brazilian patients in the eXpeRience study may affect the findings, although sample size and baseline characteristics suggest that the modeled population closely resembles Brazilian severe allergic asthma patients. Conclusion: Results indicate that omalizumab as an add-on therapy is more cost-effective than standard-of-care therapy alone for Brazilian patients with uncontrolled severe allergic asthma, based on the World Health Organization’s cost-effectiveness threshold of up to 3-times the gross domestic product.
