[Moroccan pharmacy students' knowledge and perceptions about pharmacovigilance]. / Connaissances et perception de la pharmacovigilance par les futurs pharmaciens marocains.

OBJECTIVE: The aim of this study was to evaluate the impact of an educational work groups on the knowledge and perception of 2nd year pharmacist students towards pharmacovigilance in a moroccan faculty of medicine and pharmacy. METHOD: A descriptive study conducted in pharmacology laboratory of the faculty of medicine and pharmacy of Rabat on 2nd year pharmacist students, to assess their knowledge and perception towards PV via questionnaire before and after an educational work groups. RESULTS: Among the 122 invited students, 108 responded to the questionnaire distributed before working group with a participation rate of 88,5 %. This rate increased to 95,9 % (n=117) after work groups sessions. Pre-work groups, students showed an overall low knowledge, where only 27.7 % knew the ADRs reporting sheet. In addition, most students were not well prepared to report ADR in their future practice (n=82, 75.92 %). Work groups partially offsetting this deficit, and helped to better explain to the students the reporting system. Resulting in only 28 participants maintained their declaration of inability to report ADR in their future practice (25.92 %). On the other hand, students showed a favorable perception. CONCLUSION: In this study, students expressed the desire to learn more about PV during their university education. This result led to the introduction of a system of PV working groups for 3rd and 4th year pharmacy students for the 2018-2019 academic year.

Analysis of the drug formulary and the purchasing process at a Moroccan university medical center.

AIM: To give an overview of the pharmaceutical policy in the largest medical center in Morocco, a developing country in socio-economic transition. METHODS: This is an analytical descriptive study of the drug formulary and the purchasing process carried out at the Ibn Sina University Medical Center. RESULTS: Our formulary included 830 drugs belonging to 14 classes according to the Anatomical, Therapeutic and Chemical (ATC) Classification System. There was a respective predominance of class N (21.8%), class B (13.5%), and class J (12.6%). Injectable route was dominant (46%). Drugs had a significant actual benefit in 70% (according to the French Data), reimbursable in 42.8%, essential in 29.2% according to World Health Organization (WHO) list, and in 36.9% according to the Moroccan list. The calls for tenders included 542 drugs representing 65% of the formulary, and the attribution rate was 71%. The main reason for non-attribution was the lack of offers. Generics accounted for 45% by volume and 26.5% by value. CONCLUSION: With this first study, we were able to identify key indicators on drugs used in the largest medical center in Morocco. The current challenge is to introduce pharmacoeconomics in decision making concerning the updates of the drug formulary.

[Economic impact of centralization of chemotherapy preparation: Experience of the National institute of oncology of Rabat]. / Impact économique de la centralisation de la préparation de la chimiothérapie : expérience de l'Institut national d'oncologie de Rabat.

INTRODUCTION: Centralized preparation of anticancer drugs meets quality and safety objectives. Its economic interest has been the subject of several studies, with very heterogeneous methodological approaches. OBJECTIVE: This study evaluates the economic impact of the centralization of the preparation of chemotherapy in the national institute of oncology of Rabat, the referral institute in the management of cancer in Morocco. MATERIALS AND METHODS: The analysis included 3000 preparations. It compared the costs of anticancer drugs in a centralized unit at theoretical costs in the healthcare units, modelled according to two approaches. RESULT: With a conservative approach, the impact of centralization was estimated at 80%. The centralized system made it possible to materialize 80% of the potential gain. The remaining 20% is considered a loss. It was very much related to the preparation of the expensive molecules (90%). CONCLUSION: Centralization thus allows a better distribution of roles within the hospital and provides a source of self-financing for quality improvement.

Rifampicin and isoniazid plasma concentrations in relation to adverse reactions in tuberculosis patients: a retrospective analysis.

OBJECTIVE: High concentrations of antituberculosis (anti-TB) drugs can be associated with many adverse drug reactions (ADRs). The objective of this study was to examine the plasma concentrations of rifampicin (RMP) and isoniazid (INH) in patients with and without ADRs. METHODS: Concentration monitoring data of patients treated with anti-TB drugs were retrospectively analyzed from 2009 to 2011. RMP and INH plasma concentrations were measured 2 and 3 h after drug administration respectively using high-performance liquid chromatography. RESULTS: A total of 54 out of 120 patients have experienced ADRs to anti-TB drugs. The median concentrations [interquartile range (IQR)] obtained in patients with and without ADRs were 6.7 mg/l (3.7-9.9) and 5.6 mg/l (2.9-8.6) (p = 0.56) for RMP and 4.3 mg/l (2.3-5.3) and 3.1 mg/l (1.7-4.8) (p = 0.04) for INH, respectively. Related median doses (IQR) were 8.7 mg/kg (8.0-10.0) and 8.6 mg/kg (6.5-9.9) (p = 0.42) for RMP and 4.8 mg/kg (4.3-5.0) and 4.0 mg/kg (2.8-5) (p < 0.01) for INH, respectively. Concentrations above the expected range in patients with and without ADRs were not reached for RMP, but were 76% and 65% for INH, respectively. Correlation between concentrations and doses has not been established for RMP or INH. In addition, high INH concentrations showed no association with sex, age, liver injury or renal or diabetes. CONCLUSIONS: High INH concentrations were common in patients with and without ADRs whereas RMP concentrations were low or within the normal range in most patients. Further studies are required to assess the association between high INH concentrations and the occurrence of ADRs.

[Epidemiological and clinical aspects of neurosyphilis in Morocco]. / Aspects épidémiologiques et cliniques de la neurosyphilis au Maroc.

Neurosyphilis accounts for 56%-70% of all visceral syphilis and is a complication in 5%-10% of cases of untreated syphilis. The aim of this study was to evaluate the epidemiological aspects and clinical presentations of neurosyphilis in Morocco through a series of 201 patients attending the Centre for Neurological Services at the university hospital in Rabat between 1986 and 1997. The mean age of the patients was 41.26 (SD 9.23) years (range: 17-70 years); the majority (91%) were male. The incidence of neurosyphilis in Morocco is high. From 31 cases per year in 1985, it has fallen since 1990 to reach 10 cases in 1997. Among the different clinical presentations recorded, chronic meningoencepahalitis was the commonest, followed by meningovasculitis, tabes dorsalis and optic atrophy.

A comparison study of two therapeutic protocols for neurosyphilis.

In Morocco, neurosyphilis is a serious public health problem. In the neurology service at the specialist hospital in Rabat, two drug treatments were used. Treatment A consisted of infusion over a period of 4 h of 20 MUI of penicillin G per day for 3 weeks. Treatment B consisted of infusion over a period of 6 h of 30 MUI of penicillin G per day for 10 days. Each treatment was tested on a group of eight neurosyphilitic patients as first-line treatment. On the first day of treatment, both blood and CSF pharmacokinetics were sampled for each patient. Blood and CSF were taken within 24 h. Penicillin G concentrations were determined by a microbiological method. The results obtained showed that perfusions of either 20 MUI or 30 MUI of penicillin allowed the achievement of high serum concentrations. These increased progressively until reaching their maximum at T4 h for treatment A (from 92.33 to 106.38 micrograms/ml). For treatment B, maximal concentration is obtained at T6 h (from 108 to 141.52 micrograms/ml). Penicillin concentrations decreased immediately after stopping the perfusion. At CSF levels, penicillin G concentrations were identical to serum concentrations. However, one difference was observed: a one-hour difference between the serum and CSF peaks. The CSF peak was achieved at T5 h for treatment A (0.063 to 2.25 micrograms/ml) and at T7 h for treatment B (0.92 to 2.94 micrograms/ml). The concentrations obtained were largely superior to the CMI of Treponema pallidum for both treatment A and treatment B, at 47 times and 82 times higher respectively. The recovery time of the patients was 14 h for treatment A and 24 h for B treatment. These results have shown that therapeutic method B was more efficient than A. Moreover, the evolution of penicillin G's diffusion in the CSF during treatment, of cell counts of protein level, of the VDRL test and of the gamma-globulin rate was studied.
