Gastrointestinal Drugs for Motility
The drugs that are used to increase the peristalsis movement of the digestive system are Motiligy drugs. Common motility drugs are Domperidone, Metoclopramide, Dopamine antagonist, Buspirone, Calcium channel blockers, Butylscopolamine, and Acetylcholinesterase inhibitors.
Domperidone (Domperidone is a medicine that increases the movements or contractions of the stomach and bowel. Domperidone is also used to treat nausea and vomiting caused by other drugs used to treat Parkinson’s Disease.)
Metoclopramide (Metoclopramide is used to treat the symptoms of slow stomach emptying (gastroparesis) in patients with diabetes. It works by increasing the movements or contractions of the stomach and intestines. It relieves symptoms such as nausea, vomiting, heartburn, a feeling of fullness after meals, and loss of appetite.)
Dopamine antagonist (Dopamine antagonists are drugs that keep certain types of cells in our brain from activating. They’re a key type of drug for treating certain mental health conditions and symptoms, especially psychosis and schizophrenia. In simple terms, they’re dopamine receptor blockers.)
Buspirone (Buspirone is a medication that treats anxiety.
It balances the levels of dopamine and serotonin in your brain.
These are hormones that help regulate your mood)
Butylscopolamine (Hyoscine butyl bromide, also known as scopolamine butyl bromide and
sold under the brand name Buscopan among others, is an anticholinergic medication
used to treat abdominal pain, esophageal spasms, bladder spasms, biliary colic, and renal colic)
Acetylcholinesterase inhibitors (Acetylcholinesterase inhibitors (AChEIs) also often called cholinesterase inhibitors, inhibit the enzyme acetylcholinesterase from breaking down the neurotransmitter acetylcholine into choline and acetate, thereby increasing both the level and duration of action of acetylcholine in the central nervous system, autonomic ganglia and neuromuscular junctions, which are rich in acetylcholine receptors).
Calcium channel blocker (Calcium-channel blocking agents have a potential role in the regulation of gastrointestinal tract function by decreasing smooth muscle contraction and possibly inhibiting cellular secretion. Most studies to date have concentrated on the ability of these drugs to inhibit smooth muscle contraction). Calcium channel blockers are mainly cardiovascular drugs. These drugs reduce blood pressure. So, These drugs should not be administered without the consultation of a Registered Physician.
Digestive Drugs/Digestive Enzymes are Gastrointestinal Drugs
The drugs that are used for food digestion are digestive drugs. Common digestive drugs are:
Pancreatin
Pancrelipase
Lactase
Sacrosidase
Alpha-D galactosidase
Cholic acid
Digestive enzymes are proteins that speed up the breakdown (hydrolysis) of food molecules into their separate components
(for example, sucrose is split into glucose and fructose).
These reactions happen within the gastrointestinal tract (GI),
and most of the digestive enzymes present naturally in our bodies are secreted by the pancreas into the small intestine via the pancreatic duct.
Laxative Drugs are Common Gastrointestinal Drugs
Laxatives are medicines that help resolve constipation or empty the bowel of fecal matter before procedures or surgery involving the lower bowel.
There are several different types available (see differences below) and each type works in a particular way.
Some soften or loosen up the stool, while others increase how frequently the large colon contracts which helps move the stool along the bowel. Laxative Drugs are:
Magnesium hydroxide
Magnesium sulfate
Methylcellulose
Lactulose
Polyethylene glycol 3350
Glycerin
Bisacodyl
H. pylori eradication Drugs
Drugs used to treat Helicobacter Pylori are medicines used for stomach acid inhibition, combined with antibacterial agents. Treatment is for one week with a proton pump inhibitor, antacid (or antisecretory agents), and two appropriate antibacterial agents. This one-week triple therapy does give a good eradication rate.
Amoxicillin + Clarithromycin+ Lansoprazole
Or, Amoxicillin + Clarithromycin + Omeprazole
Antidiarrheal Drugs are Common Gastrointestinal Drugs
Antidiarrheals are the name given to certain types of medicines that stop or slow diarrhea. Antidiarrheals only relieve the symptoms of diarrhea, such as an increased frequency and urgency when passing stools, they do not eliminate the cause of it. So proper treatment should be done after investigation of causes.
Antidiarrheal drugs are:
Loperamide
Racecadotril
Atropine
Bismuth subsalicylate
Lactobacillus acidophilus
Chloride channel activators are Gastrointestinal Drugs
A chloride channel activator drug is a locally acting agent that activates chloride channels in the intestine and increases the secretion of intestinal fluid that helps pass the stool. It is used to treat chronic constipation, especially in patients who have little or no benefit from stool softeners or laxatives.
Chloride channel activator drugs are:
Lubiprostone ( Lubistone 8 mcg and 24 mcg- Incepta )
Medical conditions treated with chloride channel activators
Chronic Idiopathic Constipation
Constipation
Irritable Bowel Syndrome
Irritable Bowel Syndrome with Constipation
Opioid- Induced Constipation
