RESUMO
Knowledge of drug composition consumed on the streets and the identification and quantification of their adulterants is essential for understanding unexpected side effects, tracking routes, and drug profiling. Therefore, this work aimed to determine the purity and to identify and quantify the main adulterants found in personal doses of cocaine (perico) and coca paste (bazuco) in Cartagena de Indias (Colombia). The data collected in this study describe a first attempt to introduce the qualitative and quantitative analyses of adulterants present in street drugs in Cartagena de Indias to improve surveillance. Through gas chromatography coupled to mass spectrometry (GC-MS), the purity and adulterants were quantified in 45 personal doses of cocaine powder and coca paste. 100% of the personal doses in the city were adulterated; caffeine, phenacetin, and levamisole were the main adulterants identified in cocaine. Besides the above, lidocaine was also found in coca paste. The purity of cocaine varied from 8% to almost 70%, with caffeine ranging from 6% to 42%. In the case of coca paste, the maximum content of cocaine found was 60%, while some samples contained as little as 14%. The results are consistent with other research in terms of the widespread use of caffeine as an adulterant, but they also follow the growing trend of the use of levamisole and phenacetin. The wide range of cocaine content in samples sold in the illicit market could cause undesirable effects on cocaine users who do not know the exact intended dose for consumption; so, this study intends to make these results available not only to academic, public health, and national security agencies but also to tourists entering Cartagena de Indias, so that they are aware of what they are consuming and the risks to which they are exposed.

RESUMEN Introducción: Las sulfonilureas permanecen junto con la metformina como el tratamiento farmacológico más usado para los pacientes diabéticos tipo 2, y continúan siendo los antidiabéticos más prescritos en algunas regiones del mundo. Objetivo: Evaluar la prescripción de glibenclamida en aspectos relacionados a contraindicaciones, dosificación, y prevención de efectos adversos, en el tratamiento de los pacientes diabéticos tipo 2 que acuden a una institución de salud de baja complejidad en Cartagena de Indias, Colombia. Metodología: Estudio descriptivo con enfoque desde la fármaco-epidemiología dirigido específicamente al campo de los estudios de utilización de medicamentos, basado en los datos recogidos mediante revisión de historias clínicas de 331 pacientes diabéticos tipo 2, mayores de 18 años en un centro de atención primaria en salud de la ciudad de Cartagena de Indias entre los años 2013 y 2014. Se estudiaron variables demográficas, clínicas y paraclínicas, el esquema terapéutico y la calidad de la prescripción. La información se analizó usando estadística descriptiva. Resultados: 57 % (189) de los pacientes utilizaron glibenclamida siendo un 59.3 % (153) prescrito de manera inadecuada, 45.5% (86) tenían alguna contraindicación para el empleo del medicamento. En 1 % de los pacientes de la muestra se prescribió sobrepasando el rango de dosis terapéutica Conclusiones: La calidad de la prescripción de la glibenclamida fue inadecuada en una proporción importante de pacientes, se hace necesario implementar estrategias educacionales que capaciten al personal médico para una correcta utilización de los fármacos antidiabéticos. La glibenclamida comparada con otras sulfonilureas de segunda generación nos brinda más desventajas que ventajas.
ABSTRACT Introduction: Sulfonylureas remain with metformin as the most used drug treatment for type 2 diabetic patients and remain the most prescribed anti-diabetic in some regions of the world. Target: Evaluate prescribing glyburide in aspects related to contraindications, dosage, and prevention of adverse effects, in the treatment of type 2 diabetic patients attending a health institution low complexity in Cartagena de Indias, Colombia. Methodology: Descriptive study with approach from the pharmaco-epidemiology specifically directed to the field of studies of drug use, based on the data collected through review of medical records of 331 type 2 diabetic patients over 18 years in a primary health care in the city of Cartagena de Indias between 2013 and 2014. demographic, clinical and paraclinical variables, the therapeutic plan and prescription quality were studied. Data was analyzed using descriptive statistics. Results: 57 % (189) patients using glyburide. In 59.3% (153) inappropriately prescribed glibenclamide. 45.5% (86) of the patients had a contraindication to the use of the drug. In 1% of patients were prescribed the sample exceeding the therapeutic dose range Conclusions: The quality of prescribing glyburide was inadequate in a substantial proportion of patients, it is necessary to implement educational strategies that enable medical personnel to ensure proper use of antidiabetic drugs. Glyburide compared with other second-generation sulfonylureas gives us more disadvantages than advantages.
