ABSTRACT:
OBJECTIVE:A study was conducted to evaluate drug
utilization of gastrointestinal agents in pediatric and geriatric patients. METHODS: Randomly selected 150
patients of gastrointestinal diseases
with 92 male and 58 female of age from 15-58 underwent drug utilization
evaluation of gastrointestinal agents. The frequencies of gastrointestinal
agents were calculated and compared WHO indicators of DUS (drug utilization
study) guidelines. RESULTS: Results
include patients on long term gastrointestinal drug therapy on geriartric patient, paediatric
patient. It include 92 male and 58 female patients in which 38.66% of female
patient was and 61.335 of male patient suffered from gastrointestinal diseases.
Out of 150 patients21.33% of patients was
treated with pantoprazole,12% of patients was treated with esomeprazole ,28.66% of patients was treated with
omeprazole,10.66% of patients was treated with rabeprazole,27.33% of patients
was treated with ranitidine. Oral route of administration was more than parenteral administration. Gastritis is occurred more than
inflammatory bowel disease, peptic ulcer disease and gastroesophageal
reflux disease
KEYWORDS: Drug efficacy, GIT agents, Proton pump
inhibitor, Gastritis
INTRODUCTION:
Drugs used for their effects on the gastrointestinal
system, as to control gastric acidity, regulate gastrointestinal motility and
water flow, and improve digestion. A group of pharmacologic activities, effects
on living systems and the environment, and modes of drugs and chemicals. some
of the drugs are proton pump inhibitor, antihistamines, antibiotic, antimuscarinic, antispasmodic agents.
Pharmacological activities at the molecular level of
drugs and other exogenous compounds that are used to treat diseases.A category of chemical actions and uses that result
in the prevention, treatment, cure or diagnosis of disease.
ANTACID:
The Agents that are used to reduce acid secretion in
the stomach.
ANTIDIARRHEAL:
A agents that are used to reduce intestinal motility.
Hygroscopic agents, bile acid resin, are some of the antidiarrheal
agents.
LAXATIVE:
Agents that produce a soft formed stool, and relax and
loosen the bowels, typically used over a protracted period, to relieve Constipation.
MATERIALS AND METHODS:
The population included of 92 male and 58 female
patients in which 38.66% of female patient was found to suffer from
gastrointestinal diseases and 61.335% of male patient suffered from
gastrointestinal diseases. 19.33% of patients suffered from osteoarthritis, 28%
of diabetes mellitus, 22% of hypertension,4% of COPD, 26.66% of coronary heart disease. The above patient
are treated with Pantoprazole, Esomeprazole, Omeprazole, Rabeprazole and
Ranitidine.
The 21.33% of patients was administered to
Pantoprazole, 12% of patients was administered esomeprazole,
28.66% of patients was administered to Omeprazole, 10.66% of patients was administered Rabeprazole to, 27.33% of patients was administered to
Ranitidine.
The above patients also administered 62% administered
a antibiotic, 54% of patients was administered with oral hyperglycemic, 24.66%
of patients was administered with analgesic, 70% of patients was administered
with antihypertensive, 64% of patient was administered with vitamin. The out of
150 patients the drug interaction was found in patients with 64%, 34.66%, 1.33%.
RESULT AND DISCUSSION
The results are included Patients on long term
gastrointestinal drug therapy. lactating women 92 male and 58 female patients
in which 38.66% of female patient was found to suffer from gastrointestinal
diseases and 61.335 of male patient suffered from gastrointestinal diseases.21.33%
of pantoprazole was administered to 32 patients,12%
of esomeprazole to 18 patients,28.66% of omeprazole to 42 patients,10.66% of rabeprazole
to 16 patients,27.33% of ranitidine to 41 patientsoral
route of administration was given more than parenteral
route of administration. gastritis was common than compared to inflammatory
bowel disease, peptic ulcer disease and gastroesophageal
reflux disease. Statistical method was used as descriptive state of statistical
method.
AGE DISTRIBUTION
The number of patients are 150 in which the age is
from 15-63 years. Geriatric patient has more gastrointestinal diseases than paediatric patient. Gastroenteritis is in elderly people is
acquired from contaminated objects, poor hygiene contaminated environment, infected
pets due to changes in immune response, gastrointestinal physiology use of
immunosuppressive or acid suppressive medications. Bacterial pathogens is aetiologic cause of gastrointestinal diseases in which norovirus is associated. Pathophysiological
changes that occur during aging lead to gastritis. Elderly individuals have oropharyngeal muscle dysmotility,
gastric motility, bowel motility, emptying, delayed motility are the reason for
gastrointestinal disease in these patients. The Table 1 and Figure 1 was represented
as age distribution of selected patients.

Figure.1: Shows the Age
Distribution of Patients
Absorption:
Decreased gastric secretion (acid, pepsin) leading to
gastric pH and impairement of the mucous bicarbonate
barrier lead to gastritis. Theses causes gastrointestinal dysfunction in
elderly. Reductions in esophageal peristalsis and lower esophageal sphincter
are common. The aging process reduce GI motility and GI blood flow. Leading to
reduced absorption.
Distribution:
Aging process has an effect in drug distribution in
the body. Muscle mass declines therefore drugs that are fat soluble will have
greater volume of distribution but for drugs in muscle tissue the volume of
distribution is reduced.
Metabolism:
The aging process affect metabolism of drug. Hepatic blood
flow is reduced in elderly adults which affect metabolism of drug as drug is
introduced to liver at much lower rate. Liver mass and intrinsic metabolic
activity (includes the CYP450 enzyme )is reduced during aging process. Phase I
reaction are affected more than phase II reaction. With a reduction of blood
flow to liver and reduced metabolic activity the metabolic process is reduced.
Elimination:
Many drugs are completely or partially excreted from
kidneys. Reduction in glomerular filtration rate is a
consequence of aging.
GENDER DISTRIBUTION:
The number of patient is 150 in which 92 are male and
58 are females. Males have 61.33% of gastrointestinal diseases and females have
38.66% of gastrointestinal diseases.
Males has more gastrointestinal disease than females
due to tobacco intake, alcohol, obesity. H.
pylori bacteria causes gastrointestinal disease in males. The Table 2 and
Figure 2 was represented as age distribution of selected patients.

ROUTE OF ADMINISTRATION:
No. of patients is 150 in which 104 patients are given
orally which is more than 46 patients are given parenterally.
The oral route of administration is safe and less expensive, take place with
whole length of gastrointestinal .Drugs are absorbed in small intestine .the
drug passes through gastrointestinal wall and them to liver before transported
via the blood stream to its site. The intestinal wall and liver chemically
metabolize many drugs decreasing the amount of drug reaching the blood stream.

DIAGNOSIS BASED SEGREGATION:
The number of patients is 150 in which gastritis has
more patients with 30.66% ,39 patients
of gastroesophageal reflux disease with 26% ,peptic
ulcer disease has 34 patients with 22.66% ,inflammatory bowel disease has 31
patients of 20.66%.Helicobacter pylori bacteria, norovirus
cause gastritis, poor hygiene, contaminated objects are some of the reason of
gastritis, using cocaine In autoimmune
gastritis, the immune system attacks cells in intestinal lining.So
H.pylori causes gastritis commonly than compared to
inflammatory bowel disease, peptic ulcer disease, and gastroesophageal
reflux disease. The Table 4 and Figure 4 was represented as age distribution of
selected patients

GASTROINTESTINAL AGENTS:
The number of patients is 150 in which omeprazole is given more than pantoprazole,
esomeprazole, rabeprazole,
ranitidine. Omeprazole considered safe but there are
some association of cancer, gastricatrophy. Long term
therapy are mainly associated with fundic gland
polyps and between helicobacter pylori and gastric atrophic changes. Pantoprazole
has lower affinity than omeprazole and rabeprazole for hepatic cytochromeP450 and shows no
relevant pharmacokinetic or pharmacodynamics
interactions at therapeutic doses with substrates for isoenzyme
system. In conclusion pantoprazole is superior to
ranitidine in treatment of peptic ulcer disease. It has shown efficacy when
combined with antibacterial agents in H.pylori eradication and has minimal risk of drug
interaction. Pantoprazole results in more pain relief than H2 antagonist with
more efficacy in gastrooesophageal reflux disease.

DISCUSSION:
According to reffered
article of the proton pump inhibitor omeprazole on
the gastrointestinal bacterial microbota was reported
as omeprazole administration led to decrease in
gastric helicobacter spp., while a number of investigation suggest that PPIs
also lead to a decrease in the abundance of gastric H.pylori.
According to article proton pump inhibitor usage and the risk of myocardial infarction in the
population PPIs is associated with increased risk of myocardial infarction and
H2 blockers show no such association.
The population is about 150 patients with age of 15 to
58 in which 92 are male and 58 are female. Males had increased percentage of
gastrointestinal diseases than females. Oral route of administration was
administered more than parenteral administration.
Gastritis was diagnosed more than other gastrointestinal diseases. Omeprazole was administered more than other gastrtointestinal agents
drug interaction is mild.
CONCLUSION:
These results demonstrate that 150 patients of age 15 to 58 years in which
geriatric had more gastrointestinal diseases
than paediatric patients due to
gastrointestinal physiology ,use of immunosuppressive or acid suppressive
medications Bacterial pathogens is a etiologic
cause of gastrointestinal diseases in which norovirus
is associated. Pathophysiological changes that occur
during aging lead to gastritis. Elderly individuals have oropharyngeal
muscle dysmotility, gastric motility, bowelmotility, emptying, delayed motility are the reason
for gastrointestinal disease in these patients.
Males had more gastrointestinal disease than females
due to intake of cocaine ,tobacco intake, obesity. H.pylori bacteria causes
gastrointestinal disease in males. omeprazole was
administered more than compared to ranitidine, rabeprazole,
pantoprazole Omeprazole
considered safe but there are some association of cancer, gastricatrophy.
Long term therapy are mainly associated with fundic
gland polyps and between helicobacter pylori and gastric atrophic changes. Pantoprazole
has lower affinity than omeprazole and rabeprazole for hepatic cytochrome
P450 and shows no relevant pharmacokinetic or pharmacodynamics
interactions at therapeutic doses with substrates for isoenzyme
system. So pantoprazole is superior to ranitidine in
treatment of peptic ulcer disease.it has shown
efficacy when combined with antibacterial agents in H.pylori eradication and has
minimal risk of drug interaction. Pantoprazole results in more pain relief than
H2 antagonist with more efficacy in gastrooesophageal
reflux disease.
Oral route of administration was given more than
compared to parenteral route of administration due to
safe and less expensive ,take place with whole length of gastrointestinal
.Drugs are absorbed in small intestine .the drug passes through
gastrointestinal wall and them to liver before transported via the blood stream
to its site. The intestinal wall and liver chemically metabolize many drugs
decreasing the amount of drug reaching
the blood stream.
Gastritis was more in diagnosis than compared to other
diseases due to Helicobacter pylori bacteria,
norovirus cause gastritis, poor hygiene, contaminated
objects are some of the reason of gastritis, using cocaine .In autoimmune gastritis, the immune system
attacks cells in intestinal lining. So H.pylori causes gastritis commonly than compared to
inflammatory bowel disease, peptic ulcer disease, and gastroesophageal
reflux disease.
