Background: The aim of this study was to compare the efficacy and side effects of lactulose plus traditional Persian medicine with only lactulose on the functional chronic constipation. Methods: Participants included 20 patients (10 in each group) aged 18–80 years, with major inclusion criteria of ROME III. They were assigned into two parallel therapeutic groups, including the intervention group (lactulose plus traditional Persian medicine [TPM] advices) and control group (only lactulose) through a block randomization. Weekly follow-up was done for 1 month for both groups. Results: After the intervention, the frequency of bowel habit increased significantly in patients of both groups (P = 0.001), and the frequency of hard stool defecation, sensation of painful defecation, sensation of incomplete evacuation, sensation of anorectal obstruction, and manual maneuver for evacuation were decreased significantly in patients of both groups (P < 0.001 for all comparisons and 0.025 for manual maneuver). However, the only significant difference between the two groups was more reduction in the sensation of painful defecation in the lactulose group versus lactulose plus TPM advices (P = 0.014). Conclusions: Based on the pilot study, no significant difference was shown between TPM with lactulose and lactulose only in the management of chronic functional constipation. However, the easy recommendations of TPM can be useful in improving chronic constipation.

| Introduction|| |
Chronic constipation is a common complaint in practical evaluations. Prevalence of constipation is up to 12% of people worldwide. People in the United States and Asia-Pacific suffer twice as much as their European counterparts. An epidemiological survey, which explored duration and frequency of constipation in Iran, showed the high frequency of constipation in our country. In a systematic review by Peppas et al., a high prevalence of constipation was reported as a cause for high economic and low-life quality in Pacific and European counterparts. Constipation is a common complaint in clinical practice and usually refers to persistent, difficult, infrequent, or seemingly incomplete defecation; however, low-stool frequency alone is not the sole criterion for diagnosis of constipation. According to the traditional Persian medicine (TPM) resources, E'ateghql-e-batn is a condition in which the afflicted patients develop a decrease in the frequency of bowel movements and dry and hard stool. Based on important TPM articles, constipation may be due to food dryness, low food ingestion, warmness and dryness of the colon, neurologic colon problem (intestinal sensory loss), high urination, high air temperature, hardworking, or high exercise., Management of chronic constipation should be highly individualized and dependent on cause, coexisting morbidities, and cognitive status.,
Based on TPM, prophylaxis and healthcare are preferred compared to treatment., Attention should be paid to healthy lifestyle with six important principles (1 - healthy air; 2 - healthy water and food; 3 - physical activity and repose; 4 - control of stress; 5 - control of “retention and release” and 6 - management of awakening and sleep)., Usage of the six causes must be on the basis of everybody's need. In TPM, diagnosis and treatment are based on the patient's temperament and affected organs. Other TPM-commented curative drugs are “Golghand” (a pharmaceutical composition of roses and honey) and “Cassia fistula fruit” , Descurainia Sophia, and locally abdominal massage with castor oil or olive oil.,,
Important drugs in allopathic medicine, for example, lactulose are not the final and exclusive treatment, and they have transient or intermittent effect only with long- or short-term side effects; thus, there is no effective treatment without side effects for chronic constipation. This study aims to compare the impacts of some of TPM recommendations with lactulose on functional chronic constipation.
| Methods|| |
This pilot randomized controlled clinical trial was conducted from September 2014 to October 2014 at Shahid Motahari Polyclinic in Shiraz, Iran. This project was approved by the Ethics Committee of Shiraz University of Medical Sciences and registered in IRCT (ID: IRCT2014070915587N6). The sample size was determined based on similar studies., From all the patients, 20 patients, who met the ROME III criteria, were enrolled in this study (10 in each group).
Inclusion and exclusion criteria
Patients of both sexes were considered for inclusion in the study if they were 18–80 years old and suffered from chronic functional constipation. The diagnosis of chronic functional constipation was based on the following criteria which were fulfilled for the past 3 months with symptoms onset at least 6 months before diagnosis:
- Must include two or more of the following:
- Straining during at least 25% of defecations
- Lumpy or hard stool in at least 25% of defecations
- Sensation of incomplete evacuation for at least 25% of defecations
- Sensation of anorectal obstruction/blockage for at least 25% of defecations
- Manual maneuvers to facilitate at least 25% of defecations (e.g., digital evacuation, support of the pelvic floor)
- Fewer than three defecations per week
- Loose stool being rarely present without the use of laxatives
- Insufficient criteria for irritable bowel syndrome.
The exclusion criteria were based on the suspicion to metabolic etiologies and organic disorders such as obstructive disorders and neurologic problems. Moreover, patients taking concomitant medications which may modify bowel habits were excluded from the study as were those suffering from severe liver, renal or cardiac diseases, and pregnant or breastfeeding women. For patients older than 45 years of age, exclusion of constipation secondary to colonic disease was verified by colonoscopy or a barium enema performed within the past 5 years. An organic cause of constipation was excluded by the practitioner. Patients previously exposed to lactulose were not excluded from the study.
Randomization and blinding
Random allocation software Ink (Version 1.0, May 2004) was used for randomization by a block size of five. According to a randomized, double-blind design (at the level of researcher and the person who did the statistical analysis), the patients received active lactulose or traditional medicine lifestyle , including prophylactic and curative health orders for 4 weeks.
One group received lactulose syrup and the second group took lactulose plus traditional medicine lifestyle (prophylactic and curative health) recommendations. The reference drug was lactulose syrup containing 10 g lactulose diluted in 15 ml water (lactulose, Sobhan Pharmaceuticals, Tehran, Iran).
The maximum daily dose for lactulose was 60 ml, and it was divided into 3 doses/day. Lactulose dosage alterations before and after each period were recorded. The patients were asked to increase the dose up to 50% every 3 days, if they had no bowel movements for 3 days or suffered painful defecation and hard stool, up to at most twice as much as the initial doses.
If the stool was loosened, they could reduce the dosage to half or one-third of the routine doses. After each week, the patients were also given an option to change the dosage, depending on the efficacy and their tolerance of the drug. No other treatments for constipation were allowed during the study.
Throughout the study, the patients in the lactulose group were instructed to follow their usual diet, but those of the lactulose group plus TPM schemes were instructed to follow their diet based on TPM schemes or instruction. The recommendation of TPM administrated to the patients of the other group is shown in Box 1.
Data collection and evaluation of the patients
At enrollment, a complete history was taken and physical examination done by a physician who was not involved in the study. Some variables including the number of stool frequency, hard stool, painful defecation, sensation of incomplete evacuation, sensation of anorectal obstruction, and manual maneuvers were recorded. The patients were requested to refer to the on-call physician if they developed more than 7 days lack of bowel movement or were confronted with any complication. TPM schemes were evaluated with a questionnaire filled out daily by patients of the lactulose group plus TPM and followed weekly by the staff.
Efficacy and tolerance assessment
Clinical efficacy and tolerance were assessed using a weekly card in which the patients reported the number of defecations and the following symptoms: hard stool, painful defecation, sensation of incomplete evacuation, sensation of anorectal obstruction, and manual maneuvers. These symptoms were evaluated on a five-point Likert scale ranging from 0 (never or rarely), 1 (sometimes), 2 (often), 3 (most of the times), and 4 (always) separately. At the 4th and 8th weeks of the follow-up of the patients, the patients' overall improvement and tolerance to treatment were assessed, regardless of discontinuation of the medication. After the first 2 weeks, the medication continued for further 2 weeks after obtaining the patients' agreement.
Response to treatment was defined as a reduction or elimination of ROME III criteria after the 4th week. Patients were considered as failure and withdrawn from the study if they had no bowel movement for 7 days or developed fecal impaction at any stage. The incidence and severity of gastrointestinal (GI) adverse events including flatulence, abdominal pain, and treatment compliance were monitored at the end of the 2nd and 4th weeks.
Long-term follow-up of the patients
After completion of the protocol, the patients were followed to take lactulose or lactulose plus TPM schemes for 2 additional months to evaluate the long-term efficacy and safety of the treatment. Body weight and height were measured for all the patients at the time of selection for body mass index measurement.
This project was approved by the Ethics Committee of the Shiraz Medical University. All the patients were informed verbally by a physician and gave their written informed consent for the study before enrollment. The patients were referred by the gastroenterologist after careful examination and with the diagnosis of chronic functional (idiopathic) constipation.
Statistical analysis was performed using SPSS version 15.0 (SPSS Inc., Chicago, IL, USA). Data were presented as mean ± standard deviation (SD) for quantitative data and frequency plus percentage of quantitative data. Student's t-test, repeated measure ANOVA, and Chi-square were used to determine the differences. The statistical significance level of α was considered 0.05.
| Results|| |
Among 28 patients who were referred to polyclinic, 22 cases who met the ROME III criteria for constipation were enrolled in the study. Four out of 22 patients (two per groups) withdrew from the study due to personal causes. At the end of the study, 18 patients (lactulose: 9 and lactulose plus TPM advices: 9) were analyzed [Figure 1].

In all patients, the duration of constipation was more than 6 months. Five out of nine patients in the lactulose and three out of nine in the lactulose plus TPM groups had a history of receiving multiple medications over 6 months without suitable therapeutic effects.
Response to treatments
The effects of 4-week treatment with lactulose only and lactulose plus TPM advices for patients with chronic constipation are shown in [Table 2]. Increasing significantly in bowel habit times in patients of both groups, following the intervention (P = 0.001). The frequency of hard stool defecation, sensation of painful defecation, sensation of incomplete evacuation, sensation of anorectal obstruction, and doing manual maneuver for evacuation were decreased significantly in patients of both groups, following the intervention (P < 0.001 for all except 0.025 for manual maneuver) as shown in [Table 2] and [Figure 2].

The same pattern was observed in both groups in all outcomes due to interventions, except in sensation of painful defecation which was significantly decreased in patients who received lactulose only in comparison to the another group (P = 0.014).
Changing occurrence in the dosage of lactulose consumption
In six out of nine patients who received lactulose plus TPM recommendation, the dose of lactulose consumption decreased, and two of them discontinued consumption of lactulose during the study due to sensation of well-being and cure of constipation. [Table 3] shows a statistically significant difference in decreasing the dosage of lactulose consumption between the two groups (P = 0.001).

The outflow of the patients from ROME III criteria of constipation
At the end of the study, eight out of nine in the lactulose group and seven out of nine in the lactulose plus TPM advices did not have ROME III criteria at the end of 4 weeks of the follow-up. We did not find any significant difference between the two groups in this subject [Table 4].

Significant adverse events were not reported for the patients in both groups.
| Discussion|| |
TPM sages suggest several viewpoints for the treatment of chronic constipation. TPM is a holistic medicine, and its therapeutic advice is based on individual differences among patients. The first-line intervention for treatment of the chronic disease as well as constipation (E'ateghql-e-batn) is correcting the lifestyle of the patients based on TPM suggestion., Modern medicine has defined changing lifestyle as an important way for treatment of functional constipation. Recent studies revealed the effect of facilitation of natural anthraquinone drugs such as Senna, cascara, Frangula, and Olea for stool defecation. Besides, most patients with chronic constipation prefer to use available, simple, and safe ways and take natural laxative rather than chemical medicine to cure their problems.
The primary aim of this study was to compare the efficacy, acceptability, and cost-effectiveness of the combination of lactulose plus TPM suggestions and lactulose without TPM suggestions.
As lactulose is metabolized by the colonic bacterial flora to produce short-chain fatty acids, one would expect that its laxative effect would be associated with a notable production of gases including carbon monoxide, methane, and hydrogen. Most of the common side effects attributed to lactulose such as abdominal pain, bloating, and flatus are thought to result from this colonic fermentation. In oral drugs, laxatives have been used very frequently in constipated patients.
Some studies have focused on the comparison of different medicaments with lactulose. Polyethylene glycol is a well-tolerated medicine which has been repeatedly compared to lactulose in constipated patients. On the other hand, some herbal medicaments such as a Senna-fiber combination (10 ml/daily) have also been compared to lactulose (15 ml/twice daily) and a matched placebo in geriatric constipation. During a period of 14 days in that study, the mean daily bowel frequency as well as ease of evacuation and stool consistency scores was found greater in Senna-fiber as compared to lactulose.,
In this study, both treatment methods had similar efficacy in relieving the symptoms, and most patients in both groups were did not have ROME III criteria of constipation. Pain sensation during defecation decreased more in patients who received lactulose only compared to the patients of the other group; the recent result needs to be investigated further, but also this may be referred to palliative effect of lactulose. These results reveal that the lactulose plus TPM advice group was better than the lactulose group in practice and patients verbally.
No significant adverse events were reported by the patients. The lesser chance of recovery in this study may be due to chronicity of the disease in most of the patients and history of receiving multiple drugs and tolerance to medication. Finally, it should be noted that the study was designed as a pilot, the number of the cases was low, and the intervention period lasted only for 1 month.
Preventive measures (six basic principles) and therapeutic schemes according to TPM sources maintain the health of other body organs, especially alleviating GI problems and constipation., According to this study, preventive measures recommended by TPM sages show their positive effects gradually and more prominent by reducing the consumption dosage of lactulose by patients located in B group. These measures are safe and inexpensive; however, having a healthy lifestyle based on TPM recommendations seems difficult at the starting point. Many patients are interested in using TPM recommendations and prioritize it to conventional medicines.
Strengths and limitations
The blinded trial and close follow-up were done in the study. Clinical efficacy and tolerance were assessed weekly by the staff. Necessary visits by gastroenterologist and laboratory tests were repeated for all patients if needed. The small sample size of the study was the main limitation of this study.
| Conclusions|| |
Traditional medicine lifestyle method is a cheap and available method with good efficacy and can be used in treatment of chronic constipation.
