RESUMO
BACKGROUND: Lisdexamfetamine (LDX) and Methylphenidate (MPH) are stimulant agents that have been shown to provide significant benefits in the management of attention-deficit/hyperactivity disorder (ADHD) in patients. AIM: This study aimed to assess the cost-effectiveness and the budget impact of LDX compared to MPH as the first-line treatment for ADHD. METHODS: A one-year cost-effectiveness analysis (CEA) was conducted to compare the effects of LDX and MPH in reducing disease symptoms and patient costs and improving quality of life (QoL) from a social perspective. Clinical data were obtained using the EQ-5D questionnaire. In contrast, economic data were sourced from the official website of the Iranian Food and Drug Association (FDA), the national book of tariffs, and specific questionnaires designed to evaluate patients' direct and indirect costs. 197 patients were included in the study, including individuals who sought psychiatric evaluation at a hospital in Mashhad and those who obtained ADHD medications from governmental pharmacies. The cost-effectiveness of the study medicine was assessed using the decision tree method, and the results were presented as the Incremental Cost-Effectiveness Ratio (ICER). Deterministic Sensitivity Analysis (DSA) and Probabilistic Sensitivity Analysis (PSA) were performed to assess the robustness of the findings. Additionally, a Budget Impact Analysis (BIA) was conducted over five years, considering three different scenarios, to evaluate the financial implications of incorporating LDX into the national pharmaceutical system. RESULTS: The ICER for LDX therapy compared to MPH was estimated at USD 264.28 (with an incremental cost of USD 54.9, incremental effectiveness of 0.208, and Quality-Adjusted Life Years (QALYs) gained of 0.765). The PSA indicated a 0.994% probability of LDX being cost-effective, considering a threshold of USD 2450 per QALY. Furthermore, the DSA revealed that the acquisition cost of LDX influenced the model's sensitivity. The BIA demonstrated that incorporating LDX into Iran's healthcare system would result in a financial burden of approximately $368,566 in the first year, representing an additional cost of $11,154 compared to the non-availability of this medicine and the use of previous medications. It is projected that by 2027, the financial burden of treating ADHD with LDX will reach approximately USD 443,879 over five years, amounting to an increase of $71,154 compared to the absence of this medicine. CONCLUSION: From a social perspective, the inclusion of LDX in the treatment regimen for ADHD is associated with higher costs and an increased financial burden. However, based on our analysis, LDX appears to be a cost-effective choice for managing ADHD in Iran when compared to MPH.
RESUMO
PURPOSE: Cancer is the second leading cause of death in the world after cardiovascular disease. The present study aimed to investigate the affordability and physical access to chemotherapy drugs among patients with one of the three common cancers of the breast, stomach, and colon in the city of Mashhad, Iran, in 2021. METHODS: This was a descriptive cross-sectional study. Twenty drug stores including two public and 18 privates in Mashhad were evaluated. Data was collected by consistent stay in the drug stores or pharmacies. For each oncology medicine, selling price, lowest general price, and availability were investigated. Three approaches have been experimented to calculate the affordability of anticancer medicines in this study. RESULTS: Out of 28 studied medicines from public and private drug stores, 15 (53.5%) received very low, 8 (28.5%) relatively high, and 2 (7%) high access scores. The generic docetaxel brand's ultra-drug and trastuzumab (AryoTrust) were the most available drugs, but the doxorubicin (Ebewe), oxaliplatin (Mylan), and trastuzumab (Herceptin) were not available to the individuals with cancer. Also, the first approach (based on income decile) indicated that insured patients from all income deciles were able to pay the costs of the lowest price drugs of the DCF drug regimen, and if the patients were insured and belonged to the ninth income decile, they had the financial ability to buy drugs at the lowest price of the FLO drug regimen. CONCLUSION: Unaffordability of cancer medicines can lead to treatment abandonment and increase inequality in access to healthcare services. Therefore, this requires immediate attention of policy makers to be planned in order to ensure to reducing the costs of medicines for patients and increasing patient access to anticancer medicines.
