These medications are can be classified based upon their use: drugs for nausea and vomiting (antiemetics), prokinetic agents, laxatives, antidiarrheal agents, drugs for acid peptic disease, drugs for irritable bowel syndrome, inflammatory bowel disease and, of course, miscellaneous. Agents used for gastrointestinal disease rarely cause liver injury. One reason for this is that they are often locally active and result in little systemic exposure. The immunomodulatory agents used to treat inflammatory bowel disease are an exception, being given systemically, often intravenously and capable of causing liver injury, although not very frequently.</p><p>Antidiarrheal agents include bulk forming agents, hydroscopic agents, bile acid resins, bismuth, inhibitors of intestinal motility, non-absorbed antibiotics and hormones. Bulk forming agents include methylcellulose; hydroscopic agents include pectin and kaolin; bile acid resins are cholestyramine, colestipol and colesevalam; inhibitors of intestinal motility include opioids such as diphenoxylate and loperamide. Antibiotics include rifamycin and rifaximin which are non-absorbed and are used for travelers' diarrhea. Hormones with antidiarrheal activity include octretide and somatostatin. Most antidiarrheal agents are active locally in the small intestine and colon and are largely not absorbed. Some, however, have been implicated in rare causes of liver injury (senna, cascara, cholestyramine). Telotristat is a relatively new agent that inhibits the synthesis of serotonin and is used specifically for the diarrhea of carcinoid syndrome. Agents discussed in LiverTox include the following, which are linked to the specific drug record:</p><ul><li class="half_rhythm"><div>Bismuth</div></li><li class="half_rhythm"><div>

These agents are some of the most commonly taken medications and are very well tolerated, most being available both by prescription and over-the-counter. While many of these drugs are approved for use in duodenal and gastric ulcer disease, their major use is for acid reflux and indigestion.

Many of these therapies are not systemically absorbed and none are considered particularly hepatotoxic. Naldemedine and naloxegol are opioid antagonists and are used to treat the constipation associated with opioid use.

Symptomatic therapies with antidiarrheal agents, drugs for constipation, analgesics, prokinetic agents or antispasmotics are often applied. Medications developed specifically for irritable bowel syndrome include agents that affect specific gastrointestinal receptors or hormones and include tegaserod, alosetron, linaclotide, plecanatide, prucalopride, and lubiprostone. None of these agents, however, is particularly hepatotoxic. Eluxadoline is a unique agent that is used to treat diarrhea-predominant irritable bowel syndrome. It is a mixed opioid receptor agonist (mu) and antagonist (delta) and can cause spasm of the sphincter of Oddi and pancreatitis accompaniend by marked serum aminotransferase elevations. Linaclotide and plecanatide are guanylate cyclase C receptor agonists and are used to treat chronic idiopathic constipation or "constipation predominant" irritable bowel syndrome. Similarly, cisapride, prucalopride and tegaserod are serotonin type 4 receptor agonists that are used for chronic idiopathic constipation.
