In the present study a total of 103 subjects were screened.
There were 22 screen failures as they were not meeting the inclusion /
exclusion criteria. Of these subjects, 81 subjects were randomized into two
groups, 40 subjects in Ayurin Plus
group and 41 in the Cystone group. A total of 19 subjects dropped out from the
study. A total of 62 subjects (30 subjects in the Ayurin Plus group and 32
subjects in Cystone group) completed the study.
Age
and Sex wise distribution of Subjects
The average age of subjects in the
Ayurin Plus group was found to be 36.53 ± 10.58 years while in the Cystone group
it was found to be 37.09 ± 11.92 years. There was no significant difference in
the average age of subjects in the two study groups.
There were a total of 18 Males and 12 Females in
Ayurin group while there were 20 Males and 12 Females in Cystone Group. In the
Ayurin group there were 20 subjects who were in the age group of 18 to 40 years
and in Cystone Group there were 19 subjects who were in this age group. 8
subjects in Ayurin group were in the age group of 41-50 years, 1 subject in the
age group of 51-60 while 1 in the age group of 61-70 years. 8 subjects in the
Cystone group were in the age group of 41-50 years, 5 subjects in the age group
of 51-60 years.
Prakriti wise distribution:
In
Ayurin group, there were 8 subjects of Vata-Pittaja and 2 subjects of
Vata-Kaphaja Prakruti, 9 subjects of Kapha-Pittaja Prakruti, 5 subjects of
Pitta-Kaphaja Prakruti and 6 subjects of Pitta-Vataja Prakruti. In Cystone
group, there were 3 subjects of Vata-Kaphaja Prakruti, 4 subjects of
Kapha-Pittaja Prakruti, 5 subjects of Pitta-Kaphaja Prakruti, 15 subjects of
Pitta Vataja Prakruti and 5 subjects of Vata- Pittaja Prakruti.
Evaluation of
effect on Renal Calculi
At the baseline visit, it was observed that in the Ayurin
Group there were 46 calculi at baseline visit while at 45th Day and
90th Day the number of calculi reduced to 14 and 10 respectively
i.e. 32 calculi were expelled by the 45th Day and 36 calculi were
expelled by the 90th Day. In the Cystone Group 44 calculi were
present at baseline which reduced to 23 at the end of day 45 and 13 at the end
of 90 days i.e. 21 calculi expelled by the end of 45 days and 31 calculi
expelled by the end of 90 days in this Group. There was a significant reduction
in no of stones from baseline to day 45 and day 90 in both the groups. On
analysis between the groups it was observed that Ayurin capsules showed a
significant reduction in the no of stones at the end of 45 days.
Complete expulsion of Renal Calculi
Out of 30 subjects in the Ayurin Plus group, 21 (70%)
subjects showed complete expulsion of renal calculi while in Cystone group out
of 32 subjects, 19 (59.37%) subjects showed complete expulsion of renal
calculi. When compared between the groups, the difference was statistically
insignificant (p > 0.05).
Reduction in size of Renal calculi
At the baseline visit, the mean size of renal calculi was
6.55 ± 1.68 mm in Ayurin Plus group which reduced to 5.93 ± 2.81 mm (p > 0.05) on day 45 and
further reduced significantly (p < 0.05) to 4.5 ± 1.56 mm on day 90. At the baseline
visit, the mean size of renal calculi in Cystone Group was 6.21 ± 1.47 mm which
reduced to 5.88 ± 1.64 mm (p > 0.05) on
day 45 and 6 ± 1.77 mm at the end of the study (p > 0.05).
Evaluation of effect
on Clinical symptoms
A) Pain in abdomen
Pain in the abdomen due to real stone was assessed using VAS. In Ayurin Plus group,
the mean abdominal pain score at baseline was 55.86 ±14.52,
which reduced significantly to 25.55 ±21.81,
12±21.90 and 9.2±12.88 on day 30, day 60 and day 90 respectively. In Cystone
group, the mean abdominal pain score at baseline was 53.43±18.94, which reduced significantly to 32.41±18.83, 14.8±20.43 and
15.93±19.15 on day 30, day 60 and day 90 respectively. When compared between
the groups, the difference was statistically insignificant (p > 0.05).
B) Number of pain episodes
At the baseline visit, the average
numbers of abdominal pain episodes were 2.03 ± 1.48 in Ayurin Plus group, which
reduced significantly (p < 0.05) to 0.20 ±
0.5, 0.157 ± 0.50 and 0.086 ± 0.288 on day 30, day 60 and day 90 respectively. At the baseline visit,
the average numbers of abdominal pain episodes were 1.72 ± 1.19 in Cystone
group, which reduced significantly (p < 0.05) to 0.40 ± 0.84, 0.16 ± 0.63 and 0.172 ± 0.468 on day 30, day 60 and day 90 respectively. When compared between the groups, the
difference was statistically insignificant (p > 0.05).
C) Other symptoms
At the baseline visit, 23 subjects
were having burning micturition in Ayurin Plus group. The number of subjects
having burning micturition was reduced to 9, 6
and 1 on day 30, day 60 and day 90 respectively. At the baseline visit, 22 subjects were having burning micturition in
Cystone group. The number of subjects having burning micturition reduced to 9,
5 and 6 on day 30, day 60 and day 90 respectively.
At the baseline visit, 4 subjects
were having hematuria in Ayurin Plus group. The number of subjects having
hematuria reduced to 2, 0 and 0 on day 30, day 60 and day 90
respectively. At the baseline visit, 4
subjects were having hematuria in Cystone group. The number of subjects having
hematuria reduced to 4, 3 and 2 on day 30, day 60 and day 90
respectively.
At the baseline visit, 12 subjects
were having painful micturition in Ayurin Plus group. The number of subjects
having painful micturition reduced to 4, 2
and 1 on day 30, day 60 and day 90 respectively. At the baseline visit, 22 subjects were having painful micturition in
Cystone group. The number of subjects having painful micturition reduced to 4,
3 and 3 on day 30, day 60 and day 90 respectively. When compared between the
groups, the difference was statistically insignificant (p > 0.05).
Requirement of rescue medicine
No subject of Ayurin Plus group
required rescue medication like NSAID/Anti-spasmodic for management of pain in the
abdomen, while 2 (6.25%) subjects from Cystone group required rescue medication
at least once during the study period.
Assessment of safety (Vitals and Lab Parameter)
The vital parameters such as pulse rate, body temperature,
respiratory rate, and blood pressure and laboratory investigations like mean
renal profile, liver profile, lipid profile and CBC, ESR, Hb%, BSL-F were
within normal limits both at the baseline visit and at the end of the study.
Adverse events
Out of 81 subjects, 36 were reported to have AE. In
Ayurin Plus group, there were 30 adverse events (AEs) such as a cough, fever,
nausea, insomnia, loose motion and hyperacidity during the trial. All the 30
AEs were unrelated to the study drug. In Cystone group, there were 39 adverse
events (AEs) such as a cough, fever, nausea, insomnia, loose motion and
hyperacidity during the trial. Among 39 AEs, 37 AEs were unrelated, while 2
were unlikely related to the study drug. No treatment or interruption of the
study drug or procedure was required to resolve these episodes. Three was one
SAE reported in the Ayurin Plus group. The SAE was reported to the IEC and was
followed till complete resolution. SAE was not related to the study drug or
procedure. The Majority of patients showed excellent tolerability to both the
study drugs.
