Objectives: This study aimed to evaluate the safety and efficacy of TumsUP drops in the treatment of infantile colic in infants and toddlers. Setting and Design: An active post-marketing surveillance study was conducted in the department of pediatrics of 4 hospitals from August 2020 to February 2021. Material and Methods: A total of 200 patients aged two weeks to two years, with symptoms of infantile colic for >3 hours/day, occurring >3 days/week were enrolled. TumsUP (A fixed-dose combination of simethicone 40 mg, dill oil 0.005 mL, and fennel oil 0.0007 mL) oral drops were administered for 7 days. The safety of the study drug and its efficacy in infantile colic symptoms were assessed after the end of the treatment. Results: Among 200 patients, 4 (2%) adverse events (AEs) were reported. They were mild, not related to the study drug, and resolved without sequelae. The mean crying time was reduced from 3.35±1.68 hours/day at baseline to 0.37±0.67 hours/day on day 7 (mean reduction: -2.98; 95%CI: -3.24 to -2.72, p<0.001). The mean number of daily episodes of colic reduced from 3.09±1.90 at baseline to 0.47±0.88 on day 7 (mean difference: -2.61; 95%CI: -2.90 to -2.33; p<0.001). A statistically significant (p<0.001) reduction was observed in excessive crying, fussing, sleep disturbances, clenching of fists, bending of arms and legs towards the belly, bloated tummy, redness of the face, flatulence and milk regurgitation on Day 7 as compared to the baseline. Complete remission of infantile colic was reported in 67.84% of patients after 7 days of treatment. Conclusion: TumsUP reduced the duration and severity of infantile colic and showed good safety, efficacy and tolerability.

Introduction

Excessive crying among infants is one of the most common complaints for which parents seek pediatric consultation. [1] A leading cause of excessive crying is infantile colic, [2] characterized by episodes of inconsolable crying for more than three hours daily, more than three days per week, for longer than three weeks (Wessel’s rule of threes).[1,3] Recently, the Wessel criteria have been further refined in the Rome classification of functional gastrointestinal disorders (Rome IV), with the replacement of the three weeks duration criterion with a 7-day duration criterion.[1] Various causes have been suggested, such as alterations in fecal microflora, intolerance to cow’s milk protein or lactose, abnormal gastrointestinal function, increased serotonin secretion, poor feeding technique, and maternal smoking or nicotine replacement therapy.[3] Symptoms of infantile colic include loud piercing cries with hypertonia, facial flushing, withdrawal of legs towards the abdomen, clenching of the fists and flatulence. The crying starts and stops abruptly. [4] There are no established guidelines for the treatment, [4,5] and pharmacological agents are not recommended. [2]

Simethicone is a non-absorbable, de-foaming agent that decreases the surface tension of gut mucus, allowing gas bubbles within the gut to coalesce and promoting easier expulsion of intestinal air. Evidence indicates that herbal preparations like fennel oil and dill oil might reduce crying time.[5] We aimed to evaluate the safety and efficacy of a fixed-dose combination (FDC) of simethicone, dill oil, and fennel oil (TumsUP drops) in the treatment of infantile colic.

Material And Methods

Study Design and Setting

This was an open-label, multicentric, prospective, single-arm, active post-marketing surveillance study to evaluate the safety and efficacy of TumsUP drops in infantile colic patients aged 2 weeks to 2 years. The study was conducted at four centres across India from August 2020 to February 2021. The primary objective was to assess the safety and tolerability of the TumsUP drops, and the secondary objective was to evaluate their efficacy in treating infantile colic. 


Ethics: The study was conducted according to the International Council for Harmonization (ICH) E6 (R2) Guideline for Good Clinical Practice (GCP), and Declaration of Helsinki (Brazil 2013), New Drugs and Clinical Trials Rules, 2019 of Central Drugs Standard Control Organization (CDSCO), Ministry of health and family welfare, Government of India, Ethical Guidelines for Biomedical Research on Human Participants, Indian Council of Medical Research (ICMR) 2017. The study protocol, informed consent documents and other relevant documents were submitted to the respective site institutional ethics committee and were approved by the same. The trial was initiated only after obtaining approval from the respective Institutional Ethics Committees. The clinical trial was registered prospectively with the Clinical Trial Registry of India [CTRI No: CTRI/2020/04/024552].

The parents of the patients were informed about the purpose of the study, the study drug, its effects, the duration of the trial, procedures and the overall plan of the study. Informed consent was obtained from the parents before the enrolment of their children in the study. They were free to withdraw their participation from the study at any time without providing any reason. The investigators could also withdraw any participant from the study if they deemed it appropriate due to safety or ethical reasons or if it was considered detrimental to the well-being of the participant.

Participants: A total of 200 patients aged two weeks to two years, with symptoms of infantile colic for more than 3 hours/day, occurring more than 3 days/week were enrolled. The patients with a history of hyperbilirubinemia, recently diagnosed illness or gastrointestinal disorders, presence of fever, any infection, or congenital anomalies at the time of screening were not considered for the enrolment.

Study Procedure: The history was noted by interviewing the parents. Clinical examination and symptomatic evaluation were carried out and assessed for the eligibility criteria. TumsUP drops containing Simethicone 40 mg, Dill oil 0.005 mL, and Fennel oil 0.0007 mL as fixed-dose combination formulation manufactured by Zuventus Healthcare Limited, Mumbai, India administered for 7 days. Parents were advised by the investigator for the administration of TumsUP drops. The dosage used in this trial was based on the age of the participants as below:


  • Infants (Below six months of age): five to 10 drops four times daily, 15 minutes before the feed.
  • Infants (six to 12 months of age): 10-20 drops four times daily, 15 minutes before the feed.
  • Toddlers (one to two years of age): 20 drops four times daily, 15 minutes before the feed.

All the patients were followed-up at the end of the treatment on Day 7 and symptomatic evaluation and clinical examination were done, along with the occurrence of any adverse event(s).

Outcome Measures: The primary endpoints were the number of patients developing adverse events (AEs) and investigators’ and parents’ assessment of response to the therapy at the end of the study. The secondary endpoints were a reduction in crying time and severity of infantile colic symptoms from baseline to the end of the treatment period and the number of participants with complete remission at the end of the treatment period.

The assessment of reduction in the severity of symptoms from baseline to the end of the treatment was based on the score of the following symptoms: excessive crying, fussing, sleep disturbance, clenching of fists, bending of arms and legs towards the belly, bloated tummy, redness of the face, flatulence, and milk regurgitation. These signs and symptoms are often seen with infantile colic. [5] The severity score for infantile colic symptoms was defined on a 5-point scale as follows: 5: Much Worse; 4: Somewhat Worse; 3: Slightly improvement; 2: Somewhat Better; 1: Much Better. The investigators and parents were asked to provide their assessment of response to therapy on a scale of one to four, with one indicating poor and four indicating excellent.

Statistical Analysis: The occurrence of infantile colic is varied and reported in up to 40% of infants. [4] Based on the literature, 18-20% of crying duration was reduced with the simethicone treatment compared to the baseline. [6] The statistical calculations were done based on the assumption. A total of 181 subjects were required to detect at least a 25% reduction in crying time at 5% significance with 80% power. Assuming a drop-out rate of 10%, 200 patients were enrolled in the study. Descriptive statistics have been used to summarize the baseline characteristics as mean ± standard deviation (SD) or percentage (%).

The crying duration at the baseline and the end of the treatment was compared using paired t-test. The severity of colic based on the symptom scores at baseline and the end of day 7 was compared using the paired t-test. The statistically analyzed results were presented with a significance level of 0.05 and 95% confidence intervals.

Results

A total of 200 patients were screened and enrolled in this study. Of these, 97 (48.5%) were aged less than six months, 34 (17%) were aged six to 12 months, and 69 (34.5%) were aged one to two years. The majority of the patients [127 (63.50%)] were breastfeeding. All 200 patients had excessive crying problems. Demographic and baseline characteristics are presented in Table 1. All enrolled patients who received at least one dose of the study drug were considered and analyzed for safety. One patient was excluded from the efficacy analysis due to a protocol deviation. The details of the disposition of subjects in the study are given in Figure 1.

Discussion

Infantile colic affects approximately 10% to 40% of infants worldwide. [3] Although benign and usually self-limiting, the pain causes considerable distress to the infant and children. Persistent infantile colic can lead to parental fatigue, strained parental relationships, and poor parental engagement with their infant. [7] Although many factors have been suspected, the exact cause of infantile colic is poorly understood, and the clinical management is often guided by the physician’s experience, as there are no treatment guidelines.[5] On the other hand, there is an excess of information on the internet; much of this advice is conflicting and possibly adds to parental confusion.

Treatment of infantile colic using oral agents can be grouped into the following categories: probiotics, pharmacological treatments (e.g., simethicone, dicyclomine hydrochloride, cimetropium bromide), and complementary therapies (including herbal agents and sucrose). [8] The intestinal microbiota in infants with colic differs from those in healthy controls and supplementation with probiotics can facilitate the colonization of beneficial bacteria.[9,10,11] Several over-the-counter medications are available for relieving the symptoms of infantile colic. The use of conventional medications is either controversial or prohibited in infants less than 6 months of age due to the side effects. [2]

To our best knowledge, this is the first time that a clinical study evaluated the safety and efficacy of FDC of simethicone, fennel oil, and dill oil in infants and toddlers for the treatment of infantile colic. The postulated mechanism in the pathogenesis of colic may be flatulence and spasm of the intestinal smooth muscle. Simethicone decreases the surface tension of gas bubbles in the GI tract and allows their removal from the GI tract. [12] The therapeutic effect of fennel oil and dill oil may be secondary to a spasmolytic action.

The antispasmodic activity of these volatile oils has been tested mainly in animals and it may be due to the blockage of voltage-dependent calcium channels. [13,14]

Simethicone, a defoaming agent, is a pharmacological agent that acts as a detergent to reduce the surface tension of bubbles in the intestinal tract, expels abdominal gas easily and reduces meteorism. It decreases abdominal distension and discomfort due to excessive gas production. [8] It has a favorable safety profile as it is not systemically absorbed. [15] In a randomized trial, 26 infants receiving simethicone had significantly reduced crying episodes in 4 to 7 days of therapy than did the infants receiving a placebo. [16,17] In an open-label trial, symptoms of colic improved in 38 (78%) infants after one day of treatment and in 44 (86%) infants after 7 days of simethicone treatment. [18]

Complementary herbal therapies have an increasingly important role in the management of infantile colic. Herbal supplements such as fennel (Foeniculum vulgare) and dill (Anethum graveolens) are widely used in gastrointestinal complications such as flatulence, indigestion, stomachache, infantile colic and intestinal gas. The volatile oil of fennel (rich in anethole) and dill (rich in carvone) possesses carminative, antioxidant and antispasmodic activity. [19,20]

Foeniculum vulgare has a significant positive effect on the duration of crying time. [21] A systemic review suggested that the preparation containing the fennel is effective in infantile colic with an overall mean reduction in crying time of -72.1 min/day.[22] In a placebo-controlled trial, a herbal extract contacting Foeniculum vulgare showed that colic in breastfed infants improves within 1 week of treatment. Crying time reduction was observed in 85.4% of subjects. [23] Alexandrovich et al assessed the efficacy of fennel on infantile colic in a randomized, double-blinded, placebo-controlled trial. Forty (65%) infants in the fennel group eliminated colic as compared to 23.7% of infants in the control group (p<0.01). Cumulative crying time at the end of treatment decreased from 13.5±1.18 to 8.8±1 hours/week to 8.8±1.2 hours/week. [24]

Anethum graveolens is having a soothing effect and is given to babies to treat gripe and relieve hiccups and colic. [20]


The carminative volatile oil in dill helps in digestion and relieves flatulence. It helps the expulsion of gases and also reduces gas formation [25] Dill oil is used in folk medicine as a carminative for the treatment of flatulence, colic and hiccups of infants and children. [26] Attarha et al. compared the effect of fennel extract vs. gripe water containing dill oil in a randomized clinical trial. Both groups revealed a statistically significant decrease in crying time on days 3 and 7. The difference between the two groups was insignificant at all times. [27]

Infantile colic is a behavioural syndrome characterized by excessive paroxysmal crying, that is most likely to occur in the evening. [28] Indeed, for infants and toddlers in this study about two-thirds of the daily total distressed behaviour was observed in the evening. Prolonged crying or fussing, particularly unsoothable crying is a source of anxiety and distress for the parents and a challenge for the healthcare givers. [5,29] TumsUP drops provided a significant reduction in infantile colic symptoms when day 7 of treatment was compared with baseline. The most associated symptom of milk regurgitation, which can cause lung complications, was resolved in all enrolled patients after the completion of 7 days of TumsUP treatment. The results of this study suggest that TumsUP drops are an effective formulation in the management of infantile colic. It showed that the TumsUP administered as oral drops for infantile colic was safe and well tolerated. There was a statistically significant reduction in crying time and number of episodes of colic per day at the end of treatment compared to that at baseline. After 7 days of treatment with TumsUP drops, 95% population showed individual symptomatic relief. Moreover, TumsUP drops achieved complete remission of abdominal colic in 2/3rd the study population. The observed clinical benefits of TumsUP drops might be due to the synergistic actions of its ingredients.

No study has investigated the effect of an FDC of simethicone, fennel oil, and dill oil on infantile colic. Hence, our study would make a valuable contribution to the literature and aid clinical practice in the treatment of infantile colic. The limitation of this study is that there was no comparative arm. Future randomized, controlled, blinded studies on the outcomes of FDC of simethicone, fennel oil, and dill oil in infantile colic with a larger sample size and a comparator arm are warranted to further strengthen the results.

Conclusion

This clinical study observed a significant symptomatic relief from infantile colic symptoms and a reduction in the crying duration and crying episodes in all the patients. There were no related adverse events, either reported or observed, during the study period. Therefore, it may be concluded that TumsUP (FDC of simethicone 40 mg, dill oil 0.005 mL, and fennel oil 0.0007 mL) is clinically safe and effective in the management of infantile colic in infants and toddlers.
