Formulación de fármaco por nueva vía de administración: Closantel Sódico, gel antiparasitario de uso veterinario contra Fasciola hepática
(Universidad Privada Norbert Wiener, 2015) Zegarra Cárdenas, Diana; Rivas Altez, Walter
The study was carried out with the purpose of formulating a medicine through a new route of administration of sodium closantel gel for veterinary use against Fasciola hepatica during the months of January to April 2015. An experimental, analytical, cross-sectional research work was conducted to elaborate a gel that meets the optimal conditions for use as an antiparasitic, taking into account the ideal physicochemical processes for the formulation of the gel in question. It should be noted that the physicochemical processes are important in the elaboration of the gel, with the fundamental basis being the interaction of the appropriate excipients, the active ingredient, adequate quantity, etc. Several excipients were considered for the preparation of the gel, finding that the use of Cremophor in different amounts is not suitable for the gel formulation. The use of Tween 80, which is employed for viscosity, is also not suitable for the gel formulation as it presented non-ideal characteristics. Poligel was used for the formulation of the gel, and incompatibilities and inconsistencies were found (Not suitable). Formula 1012 was used, in which it was observed that the use of 80 g is adequate for the gel formulation (Suitable). A formula with codification 1012 was also used, where the ideal temperature for the formulation of the gel is 70°C. The use of Polyethylene glycol in an amount of 200 mL is adequate for the formulation of the gel. In the search for alcohols for the gel formulation it was found that: the use of rectified ethanol alcohol in an amount of 100 mL is suitable, alcohol coded (1013) in an amount of 100 mL is suitable, alcohol coded (1014) in an adequate amount of 200 mL, and formula coded (1015) in an amount of 15 mL is suitable. The use of Monoethanolamine in an amount of 8.5 mL is optimal for the gel formulation. It should also be noted that the active ingredient sodium closantel does not present any inconvenience in the formulation of the gel.

Impacto de la farmacovigilancia y la gestión de reacciones adversas al fluconazol en la cadena de boticas Farmacia Universal, Lima 2025
(Universidad Privada Norbert Wiener, 2025-11-05) Martínez Ocaña, Lizbeth Pamela; Purisaca Quispe, Jonathan Gregory; Rivas Altez, Walter
The present study had the Objective: To determine the impact of pharmacovigilance on the management of adverse reactions to fluconazole in the Farmacia Universal pharmacy chain, Lima 2025. Methodology: The research was developed under a quantitative at a correlational level, with a non-experimental, cross-sectional design. The population consisted of 250 collaborators in pharmacy functions, of whom 161 workers in direct customer care, available at the time of the study, were surveyed. For data collection, a Likert-type questionnaire was applied, validated by expert judgament and with high reliability according to Cronbach’s Alpha coefficient. Results: The results showed a positive and significant correlation between the pharmacovigilance system and the management of adverse reactions to fluconazole (r=0.707; p=0.000). Continuous staff training (r=0.633) and participation in reporting processes (r=0.653) were directly associated with better identification, recording, and monitoring of adverse drug reactions. Likewise, institutional barriers (r=0.664), mainly related to the avilability of resources and organizational culture, were identified as limiting efficiency of the system. Conclusions: It is concluded that pharmacovigilance constitutes a fundamental axis to ensure patient safety and the rational use of antifungical drugs in community pharmacies. The findings support the need to strengthen training programs, implement standardized reporting protocols, and promote a culture of active notification, which Will have an impacto on the optimization of internal processes and on the generation of scientific evidence useful for public health in Perú.

Metamidofos y carbofurano en uvas (Vitis vinifera) de tres mercados de Lima Metropolitana. 2025
(Universidad Privada Norbert Wiener, 2026-02-03) Chirinos Pajuelo, Diego Alejandro; Rivas Altez, Walter
El presente estudio tuvo como objetivo determinar la concentración de plaguicidas prohibidos como Metamidofos, carbofurano entre otros en uvas (Vitis vinifera) de mercados de Lima Metropolitana, 2025. La metodología se basó en la extracción QuEChERS y el análisis por cromatografía líquida acoplada a espectrometría de masas en tándem (LC-MS/MS). Aunque el objetivo inicial se centró en Metamidofos y Carbofurano, el análisis se extendió a otros tres agroquímicos prohibidos: Clorpirifos, Monocrotofos y Metomilo, encontrándose al menos uno de ellos en 3 mercados muestreados. Los resultados obtenidos evidencian la presencia de los plaguicidas Metamidofos y carbofurano en uvas a la concentración 0.005 y 0.006 mg/kg respectivamente. Estos hallazgos evidencian una contaminación generalizada que incumple la normativa peruana y representa un grave riesgo para la salud pública debido a la exposición dietética a una mezcla de neurotóxicos, asimismo se reportaron resultados como Metomilo (hasta 0.39 mg/kg) y Monocrotofos (hasta 0.041 mg/kg), superando los Límites Máximos de Residuos (LMR) de la Comisión Europea. El mercado Mayorista de Comas y el Mercado Mayorista de Puente Piedra, presentaron la mayor carga de contaminantes en muestras de uvas. Como conclusión se evidencia que existen fallas sistémicas de control y fiscalización en el comercio local de uvas.
