Item Análisis de cumplimiento y mejoras potenciales en cosméticos con cannabis o sus derivados en establecimientos farmacéuticos de Cali: Un enfoque en la decisión 833 de 2018(Universidad Santiago de Cali, 2024) Gutierrez Corral, Miguel Angel; Amaya Londoño, Nicolas Giuseppe; Chamorro Rengifo, Andrés Felipe (Director)Cannabis, a plant with a history spanning over 4000 years, has played a vital role in various cultures, from ancient China to pre-Columbian civilizations. Initially revered for its medicinal and spiritual properties, cannabis has faced stigmatization in the modern era due to political and social influences. However, in recent decades, it has experienced a resurgence in the pharmaceutical and cosmetic fields, supported by scientific evidence of its efficacy in treating various conditions. Cannabis regulation varies by country, ranging from legalization to prohibition. In the cosmetic realm, it has become a popular ingredient due to its moisturizing and antioxidant properties. However, lack of compliance with regulations can compromise consumer safety. Evaluating compliance of cannabis products at the regulatory level is necessary to protect the population from the use of illegal products that may jeopardize health. According to this study, which focused on evaluating compliance of cosmetic products with cannabis in the city of Cali with Decision 833 of 2018 (Colombian regulation?), surveys and pie charts were used to assess labeling and consumer safety compliance. The results indicate that a important proportion of respondents (35.7%) are unaware of the existence of Decision 833 of 2018, 50% do not verify or review mandatory health notifications, and 80,6% do not review mandatory warnings on labels. This demonstrates a lack of awareness regarding the importance of health registration and mandatory warnings on labels, raising concerns about consumer safety. Increasing transparency, education, and regulation in the industry is recommended to enhance consumer confidence and ensure product safety.Item Avances y desafíos en la aplicación de espectroscopía de infrarrojo cercano (NIR) para el desarrollo de nanomateriales en biomedicina: “revisión sistemática”(Universidad Santiago de Cali, 2024) Ordoñez Moreno, Maribel; Ríos Acevedo, Jhon Jairo (Director)Item Caracterización de incidencias de reacciones adversas medicamentosas asociadas a anticoagulantes y diseño de guía de uso clínico para pacientes anticoagulados(Universidad Santiago de Cali, 2024) Vélez Hernández, Natalia; Rios Acevedo, Jhon Jairo (Director)Pathologies associated with poor blood coagulation such as DVT (deep vein thrombosis), stroke (cerebrovascular accident), venous thromboembolism, pulmonary embolism, among others; These require a drug that helps the clot that is produced inside a vein or artery not to occlude it, at this point is when anticoagulants play a very important role, being one of the most widely used groups of drugs in Colombia, for this reason a retrospective study was conducted by reviewing 150 clinical histories of anticoagulated patients in the health provider institution Hospital Universitario del Valle, in the period from 2018 to 2022, in order to identify what is the incidence of a patient to present or not an ADR (adverse drug reaction) or AE (adverse event). The age group between 40-90 years was identified, where the prevalence of presenting an undesired reaction during treatment varied according to the anticoagulant used: for Enoxaparin it was 74%, for Dalteparin it was 71%, for Apixaban it was 40% and for Heparin it was 89%. On the other hand, it was possible to identify that the most frequent adverse event was nausea with approximately 40%. Following this, the Chi-square test was performed, where correlation was observed between different variables such as the adverse event presented, the concentration of the anticoagulant and the duration of treatment; by means of these data, it was observed which of the hypotheses was fulfilled for each type of analysis, finding that there is no relationship of influence in terms of age vs. anticoagulant administered and age vs. frequency of presenting an undesired event, while there was a relationship between the other cases already mentioned.Item Desarrollo de un método alterno comprendido en la farmacopea estadounidense (USP) para la determinación cualitativa de impurezas de monoestearil maleato y alcohol estearílico presentes en el estearil fumarato sódico por cromatografía de capa fina (CCF)(Universidad Santiago de Cali, 2024) Rojas Daza, Andrés Felipe; Castro Bonilla, Duván Andrés; Flórez Flórez, Edwin (Director)In the pharmaceutical industry, analytical procedures play a crucial role in ensuring the quality, safety and efficacy of materials/products, where reproducible and reliable results are obtained.

Different tests were carried out, experimentally studying the stationary phase, modifying the proportions and solvents of the mobile phase and testing different revealing agents. Finally, an alternate procedure was proposed, where the separation of the spots of interest, their intensity and tonality were improved with RF values for sodium stearyl fumarate, stearyl alcohol and monostearyl maleate of 0,35; 0,65; 0,05; compared to what was obtained in the version of the pharmacopoeial methodology of 0,47; 0,48 and 0,40 respectively, which ensures the reliability of the resultsItem Diseño de un programa de gestión del riesgo aplicable en el proceso productivo en una central de mezclas(Universidad Santiago de Cali, 2025) Cechagua Suarez, María Angelica; Quintero Ortiz, Alejandro; Suarez Osorio, Liseth (Directora); Ruiz Pauly, Nathalie (Codirectora)Risk analysis is a systematic process used in different fields to identify, assess and control risks associated with the execution of processes, usually large-scale and branching. In the pharmaceutical 5 field, risk analysis is essential to ensure the safety and quality of medicines, so professionals in this field must be trained in techniques and methodologies for risk management. In this sense, the objective of this project was to design a risk management program applied to the production process of a mixing plant in Cali, Colombia. This process will identify and assess the risks associated with the processes and products manufactured at the plant. This makes it possible to implement preventive and corrective measures to minimize risks and ensure patient safety. The project was carried out by implementing the Failure Mode and Effects Analysis (FMEA). The risks associated with different stages of the process were identified and classified into three levels according to their severity, occurrence and ability to detect. The results indicated that 56% of risks were acceptable, 39% acceptable under specific conditions and 5% unacceptable. Corrective measures implemented included improved operating procedures, staff training, preventive maintenance and optimization of critical systems such as power supply. The study highlighted the effectiveness of FMEA in mitigating risks in critical pharmaceutical processes and stressed the importance of proactive management that includes continuous training and technological modernization. Although the limitations in infrastructure and financial resources presented challenges, the methodology adopted proved to be adaptable to the Colombian context. This model is a strategic tool for improving product quality and safety, as well as strengthening the competitiveness of pharmaceutical facilities at the national level.Item Disminución de la resistencia a ampicilina en cepas de Staphylococcus aureus resistentes a meticilina a través de nanoliposomas funcionalizados con polímeros de Hidroxipropilmetilcelulosa y Carboximetilcelulosa(Universidad Santiago de Cali, 2023) Sáenz, María Valentina; Materon Luna, Daniela; Oñate Garzon, José Fernando (Director)The methicillin-resistant strain of Staphylococcus aureus (MRSA) causes infections that are resistant to most antibiotics, becoming a public health problem. The implementation of the delivery of ampicillin, a broad-spectrum antibiotic, was evaluated to avoid enzymatic degradation and achieve localized delivery that increases biological activity. For this, nanoliposomes coated with a non-ionic polymer such as hydroxypropylmethylcellulose (HPMC) and an anionic polymer such as carboxymethylcellulose (CMC) were used, which were prepared by the ethanol injection method and coated with the layer-by-layer method. Subsequently, the physicochemical characterization was carried out, using the Z-sizer equipment, to determine the size and find the surface charge (z potential). Then, by ultracentrifugation, the encapsulated ampicillin was separated and the encapsulation efficiency was extended. Then, the microbial susceptibility test was performed on two Staphylococcus aureus strains: sensitive ATCC25923 (MSSA) and resistant ATCC43300 (MRSA) to determine the minimum inhibitory concentration (MIC). Finally, variations in the size of the nanoliposomes functionalized with ampicillin-loaded polymers will be changed, which have various sizes (400-1000 nm), polydispersity from 0.4 to 0.7, zeta potential (-51 to -79 mV) and an encapsulation efficiency of about 92% in HPMC and 77% for CMC. However, the antibacterial effect was not as expected, since the nanosystems do not allow ampicillin to be fully released and can effectively reduce the bacterial resistance of the Staphylococcus aureus (MRSA) strain.Item Estandarización de medicamentos de pediatría en un Hospital Público Nivel 1 de la Ciudad de Cali(Universidad Santiago de Cali, 2023) Hidalgo Giraldo, Laura Marcela; Chamorro Rengifo, Andrés Felipe (Director)This project standardizes the method of preparation, stability time and concentration of the drugs Amikacin 500 mg/2 mL, Betamethasone 4 mg/1 mL, Cephalexin 250 mg/5 mL, Cefradine 1 g, Furosemide 20 mg/2 mL, Penicillin g benzathine 2,400,000 U.

They are obtained through enzymatic or acid hydrolysis processes that catalyze the breaking of peptide bonds, thus obtaining bioactive peptides used in various industries due to their ability to selectively interact with other molecules, being of interest in medical research for the development of new therapies. and diagnoses. Quinoa is a rich source of peptides that contain bioactive compounds beneficial for health. Performing peptide synthesis with enzymatic hydrolysis in vitro can be complex and expensive, requiring precision in the union of amino acids and with low yields. Cheaper alternatives, such as in silico enzymatic hydrolysis, have been developed using bioinformatics tools to predict bioactive peptides. In some studies, the pharmacological potential of peptides obtained from quinoa by in silico enzymatic hydrolysis has been evaluated. This approach could significantly impact the pharmaceutical industry, facilitating the development of new drugs for chronic diseases and improving quality of life. This implies an advance in scientific and technological knowledge, especially in the pharmaceutical industry.Item Potencial farmacológico in silico de péptidos obtenidos por hidrolisis enzimática de la proteína de quinua(Universidad Santiago de Cali, 2024) Ruiz Beltrán, Daniela; Uzuriaga Perlaza, Laura Mercedes; Oñate Garzón, José Fernando (Director)Peptides, organic compounds formed by the union of amino acids, are highly valued in the pharmaceutical field due to their high specificity and low toxicity. However, in vivo research with peptides can be costly and slow. In contrast, in silico research offers significant savings in time and costs, allowing a broader search and quick analysis of possible biological activities. The enzymatic hydrolysis of proteins, a process that breaks down proteins into amino acids to reach peptides, is fundamental in this field. Quinoa, a pseudocereal native to the Andes with a high protein content, has been the subject of research for the development of new drugs. Bioinformatics tools, which predict and analyze the breakdown of chemical bonds in biological molecules, are increasingly used to design and select peptides with biological activities. Using the NCBI biology tool, the sequence of the quinoa protein was obtained and bioactive predictions were made in 5119 peptidic sequences obtained by hydrolysis of the actinidin enzyme. The bioactive peptides found can be the basis for developing new drugs to prevent and treat microbial diseases and cancer, thus improving the quality of life of peopleItem Producto cosmético a base de arcilla montmorillonita intercalada con aminoácidos para regeneración de la piel(Universidad Santiago de Cali, 2022) Romero Manzano, Sara Carolina; Leiton López, Silvana Anyolina; Ríos Acevedo, John Jairo (Director)This project evaluated the impact of incorporating amino acid-modified montmorillonite clay into an O/W cosmetic body cream on its sensory, physical-physicochemical, and microbiological stability properties. In this way, it was started by intercalating glycine, glutamine, and arginine within the previously purified clay structure by the cation exchange method and characterized by infrared spectrophotometry and thermogravimetric analysis. The intercalated clay was added to a standard cosmetic formulation and finally the physical-physicochemical, organoleptic, and microbiological stability parameters were compared in a cosmetic product with and without clay. Regarding the physical stability studies, the phenomenon of agglomeration and cremation was determined. Greater extensibility and less density were presented in the cream without clay. The microbiological studies complied with the parameters evaluated and in the organoleptic properties the cream without clay presented better acceptability in terms of its color, smell, adherence to the skin, soft sensation, and creamy texture.Item Seguimiento farmacoterapéutico bajo la metodología CTCAE en la evaluación de las reacciones adversas de la doxorrubicina en pacientes con cáncer de mama polimedicadas(Universidad Santiago de Cali, 2024) Villanueva Gallego, Isabella; Ciro Monsalve, Yhors Alexander (Director)The study deals in depth with adverse drug reactions (ADR) in breast cancer patients treated with Doxorubicin and other drugs simultaneously. It is highlighted that polymedication increases the risk of ADR, presenting interactions in 24% of the drugs administered, especially in the gastrointestinal, hematological and neurological systems. According to Naranjo's algorithm, it was observed that 64% of the ADRs have a possible relationship, 44% a probable relationship and 7% a doubtful relationship. Likewise, using the Common Terminology Criteria for Adverse Events (CTCAE), 85% of the reactions were classified as mild, 9% as moderate and 6% as severe. A remarkably high incidence of 98% was observed in patients with breast cancer, who were also under treatment with Doxorubicin and polymedication, presenting adverse reactions. This finding suggests a significant likelihood that ADRs are related to Doxorubicin administration in this specific population. The study highlights the importance of comprehensive evaluation and monitoring to prevent interactions and ADRs, proposing strategies such as pharmacotherapeutic follow-up, pharmacovigilance and education for medical staff and patients, in order to optimize safety and improve patients' quality of lifeItem Validación de proceso de manufactura de una forma farmacéutica sólida en una planta farmacéutica(Universidad Santiago de Cali, 2023) Rodriguez Escobar, Sebastian; Lindo Sanclemente, Juliana Alejandra; Ciro Monsalve, Yhors Alexander (Director)This project consists of carrying out a concurrent validation of the manufacturing process of (calcium carbonate + vitamin D), produced by Fabrifarma S.A in the city of Cali.
