Micelles bind to the intestinal enterocytes, and cholesterol and other sterols are transported from the micelles into the enterocytes by a sterol transporter. Homeostenosis and comorbidities require more frequent monitoring for adverse effects: symptoms, abnormal laboratory results, drug interactions, and drug levels. Linaclotide is a potent and selective guanylate cyclase C agonist that elicits pharmacological effects locally in the gastrointestinal tract. In contrast, radiotherapy or drugs, such as chemotherapeutic agents, cause growing anagen hairs to fall out. The damage is extensive, which involves both cell-mediated and antibody-mediated immune response, such as immune complex deposit (Table 12. In hemorrhagic stroke, a surgical evaluation should be completed to assess the need for surgical clipping of an aneurysm or other procedure to control the bleeding and prevent rebleeding and other complications. If other risk indicators are present, consider assigning to the high-risk category.
