Clinical Assessment of the Use of Propinox Hydrochloride and Scopolamine Hydrochloride in the Treatment of Abdominal Colic: A Retrospective, Comparative Study

Abstract

Objectives: The purpose of this study was to evaluate and compare the use of propinox hydrochloride and scopolamine hydrochloride in patients presenting abdominal colic (abdominal pain), in * Corresponding author. H. Rzetelna et al. 475 terms of treatment efficacy and tolerability. Material & Methods: This was an analytical, retrospective, comparative study based on hospital records of outpatients treated at Serviço de Clínica Médica do Hospital das Clínicas Costantino Otaviano (HCTCO) and at Santa Casa de Misericórdia do Rio de Janeiro, from 1988-1998. Subjects were divided into two groups: patients from Group 1 were treated with propinox hydrochloride, while patients from Group 2 were treated with scopolamine hydrochloride. Statistical analysis was performed using GraphPad Prism version 5.0. For comparison of categorical variables, we used the chi-squared or Fisher's test, while continuous variables were analyzed using ANOVA or the Student's T test. Results: A total of 1042 subjects were included, of which 525 were allocated to Group 1 and 517 to Group 2. Mean treatment duration was 9.166 days (±4.208) in Group 1 and 8.795 days (±5.052) in Group 2, with no statistically significant difference in treatment duration between the two groups (p = 0.198). All subjects in Group 1 were treated with propinox 10 mg (2 coated tablets, three times per day) while all subjects in Group 2 were treated with scopolamine hydrochloride 10 mg (2 coated tablets, three times per day). There were no statistically significant between-group differences in weight, BMI, heart rate, and respiratory rate at pre-and post-treatment; with the exception of higher post-treatment systolic blood pressure in Group 1, blood pressure measures also remained homogenous. Adverse events were reported among both treatment groups with no significant between-group difference in incidence (p = 0566). At pretreatment, pain intensity was more severe in Group 1 (p = 0.0257), while at post-treatment, there was no statistically significant difference between the two treatment groups (p = 0.895). There was a statistically significant improvement in pain intensity within both treatment groups (χ 2 = 631.4; df = 3; p < 0.0001 for Group 1 and χ 2 = 554.3; df = 3; p < 0.0001 for Group 2). Conclusion: The results obtained in this study indicate a therapeutic equivalence between propinox hydrochloride and scopolamine hydrochloride. Both treatments demonstrated good efficacy and tolerability in the treatment of abdominal colic pain, in the population evaluated.

Identification of potential inhibitors of SARS-CoV-2 S protein–ACE2 interaction by in silico drug repurposing

“…Pargeverine is an antispasmodic opioid alkaloid whose therapeutic indication is aimed at the treatment of painful spasms 66 , also, acts as anticholinergic and has a moderate and non-selective blockade of muscarinic cholinergic fibers 67 . Since cholinergic activity contribute to airway narrowing, this might be a potential agent to open airway obstruction.…”

Primer consenso centroamericano y del Caribe del síndrome de intestino irritable

“…Actúa directamente en las células del músculo liso visceral para reducir los espasmos y presenta un bloqueo moderado y no selectivo de las fibras colinérgicas muscarínicas. 82 En un estudio doble ciego con placebo en 75 pacientes con SII, el propinoxato oral (10 mg qid por 28 días) mostró una mejoría significativa y progresiva de la intensidad del dolor abdominal, de la frecuencia de las crisis del dolor y de la distensión abdominal en mayor medida que la observada en el grupo tratado con placebo. Los efectos adversos más frecuentes fueron cefalea, náusea y dolor de cabeza, pero ningún paciente tuvo que abandonar el tratamiento.…”

“…84 Rzetelna y col. compararon retrospectivamente el propinoxato y la escopolamina en 1.042 pacientes con dolor abdominal de tipo cólico y encontraron que ambos tratamientos resultaron en una mejora estadísticamente significativa en la intensidad del dolor. 82 Castillo R. comparó el propinoxato en combinación con el clonixinato de lisina y la hioscina en combinación con paracetamol en 120 pacientes con dolor abdominal de tipo cólico de origen biliar y colónico, encontrando que ambas combinaciones fueron efectivas en el tratamiento del dolor. 85 Los canales de calcio son importantes para la fisiología del intestino y en el tratamiento del SII porque regulan procesos intracelulares, como la contracción y la neurotransmisión.…”
