A comparative analysis of the Libyan national essential medicines list and the WHO model list of essential medicines

Abstract

Aim and Objectives: To examine the concordance of the Libyan Pharmaceutical List of Essential Medicines (LPLEM) with the World Health Organization Model List of Essential Medicines 2009 (WMLEM 2009). Methods: The concordance between generic medicines listed in the WMLEM 2009 (standard reference list) and the LPLEM 2006 (comparator list) was evaluated. Results: The total number of Basic Essential Medicines (BEMs) listed on the WMLEM 2009 was 347. The total number of generic medicines listed on the LPLEM was 584. Although the LPLEM has more listed medicines, only 270 (77.6%) of BEMs from the WMLEM were listed as available. However, 25 of the 77 missing medicines were deemed to have appropriate alternatives. A total of 52 medicines from the WMLEM 2009 were therefore missing from the LPLEM. Discrepancies compared to the WMLEM 2009 were identified in 15 out of 29 therapeutic sections. The highest discrepancy rate from the WMLEM 2009 was in the anti-infective section (35 missing medicines). Missing BEMs were noted in many subclassifications of the antiinfective medicines section, but omissions were particularly prevalent in the antibacterial medicines subsection (11 missing medicines). Antituberculosis medications had the highest discrepancy rate for antibacterial BEMs with one-third of the single medicines recommended by the WHO in the WMLEM 2009 not listed on the LPLEM. Of the 314 additional medicines on the LPLEM, 18 were deemed to be irrational non-essential medicines. Conclusion: The LPLEM does not include several essential medicines recommended by the WHO in the WMLEM 2009. These discrepancies may have serious public health implications for management of some infectious diseases, particularly, tuberculosis and HIV.
