RESUMO

Objectives: In this paper, we outline and compare pharmaceutical pricing and reimbursement policies for in-patent prescription medicines in three Maghreb countries, Algeria, Morocco, and Tunisia, and explore possible improvements in their pricing and reimbursement systems. Methods: The evidence informing this study comes from both an extensive literature review and a primary data collection from experts in the three studied countries. Key findings: Twenty-six local experts where interviewed Intervieweesincluded ministry officials, representatives of national regulatory authorities, health insurance organizations, pharmaceutical procurement departments and agencies, academics, private pharmaceutical-sector actors, and associations. Results show that External Reference Pricing (ERP) is the dominant pricing method for in-patent medicines in the studied countries. Value-based pricing through Health Technology Assessment (HTA) is a new concept, recently used in Tunisia to help the reimbursement decision of some in-patent medicines but not yet used in the pricing of innovative medicines in the studied countries. Reimbursement decision is mainly based on negotiations set on Internal Reference Pricing (IRP). Conclusion: Whereas each country has its specific regulations, there are many similarities in the pricing and reimbursement policies of in-patent medicines in Algeria, Morocco, and Tunisia. The ERP was found to be the dominant method to inform pricing and reimbursement decisions of in-patent medicines. Countries in the region can focus on the development of explicit value assessment systems and minimize their dependence on ERP over the longer-term. In this context, HTA will rely on local assessment of the evidence.

RESUMO

Several studies have highlighted that nutritional supplements may contain undeclared anabolic steroids that are banned by the International Olympic Committee/World Anti-Doping Agency. Any kind of abuse with these drugs is extremely dangerous because of their side effects. Thus, the control of food additives in order to protect the best consumer health and to limit fraudulent practices in the field of sports is essential. This paper describes a simple and effective qualitative gas chromatography-mass spectrometry (GC-MS) method to detect anabolic androgenic steroids (AAS): androsterone, nandrolene, dehydroepiandrosterone, 5ɑ-androstane-3ß, 17ß-diol, dihydrotestosterone, testosterone, methenolone acetate, methandienone, boldenone and fluoxymesterone, in food supplements. Methyltestosterone was used as internal standard. Target compounds were extracted with a mixture of N-pentane and di-ethylether (7.5:2.5, v/v). A good extraction recovery was obtained by our method for all the AAS (R > 88%). Crude extract was derivatized with N-methyl-N-trimethylsilyl-trifluoracetamide. Separation was performed on a GC connected to quadrupole MS detector using a 5% phenylmethylsiloxane fused silica capillary column (30 m × 0.25 mm i.d.; film thickness, 0.25 µm). Helium was used as carrier gas with a flow rate of 0.3 µl min-1 (measured at 6.1 psi 190 °C). The MS was operated in electron ionization mode (70 eV) and in selected ion monitoring (SIM). The mass spectra of the standard compounds were acquired in full SCAN mode (50-700 m/z) by infusion of a reference solution at 50 µg/ml. Three higher diagnostic ions were monitored for each compound of interest. All AAS get separated with good peak shapes and resolution factor. The total analysis time by our optimised method was only 20 min. The developed method was validated according to Laboratories International Standard regulations for specificity, precision in both liquid and solid matrixes, and memory effect. The Tolerance Interval was judged true. The limit of detection was about 10 ng/g for solid samples and 10 ng/ml for liquid samples. The developed method was then applied to the research of steroids in nine Tunisian commercially dietary supplements using for each compound of interest SIM mode for screening then SCAN mode for confirmation. One of the monitoring samples was positive to methandienone not declared on the label. Our analytical method can be beneficial for AAS screening in dietary supplements.
