WK 4 pharm Week 4: Gastrointestinal and Hepatobiliary Disorders As an advanced practice nurse, you will likely encounter patients who will present with symptoms affecting the gastrointestinal (GI) tract. Of special note, is the consideration that most symptoms concerning the GI tract are non-specific and therefore, diagnosing diagnoses of the GI tract require thoughtful and careful investigation. Similarly, hepatobiliary disorders may also mirror many of the signs and symptoms that patients present when suffering from GI disorders. How might you tease out the specific signs and symptoms between these potential disorders and body systems? What drug therapy plans will best address these disorders for your patients?

This week, you examine GI and hepatobiliary disorders. You will review a patient case study and consider those factors in recommending and prescribing a drug therapy plan fo your patient. Utilize the following case study: Patient HL comes into the clinic with the following symptoms: nausea, vomiting, and diarrhea. The patient has a history of drug abuse and possible Hepatitis C. HL is currently taking the following prescription drugs: · Synthroid 100 mcg daily · Nifedipine 30 mg daily · Prednisone 10 mg daily To Prepare · Review the case study assigned by your Instructor for this Assignment · Reflect on the patient’s symptoms, medical history, and drugs currently prescribed. · Think about a possible diagnosis for the patient. Consider whether the patient has a disorder related to the gastrointestinal and hepatobiliary system or whether the symptoms are the result of a disorder from another system or other factors, such as pregnancy, drugs, or a psychological disorder. · Consider an appropriate drug therapy plan based on the patient’s history, diagnosis, and drugs currently prescribed. Write a 1-page paper that addresses the following: · Explain your diagnosis for the patient, including your rationale for the diagnosis. · Describe an appropriate drug therapy plan based on the patient’s history, diagnosis, and drugs currently prescribed. · Justify why you would recommend this drug therapy plan for this patient. Be specific and provide examples.

Patient HL comes into the clinic with the following symptoms: nausea, vomiting, and diarrhea. The patient has a history of drug abuse and possible Hepatitis C. HL is currently taking the following prescription drugs: · Synthroid 100 mcg daily · Nifedipine 30 mg daily · Prednisone 10 mg daily There are many causes of nausea and vomiting, most commonly these symptoms are caused by ingestion of substances or drugs, gastrointestinal disorders or metabolic disorders (Arcangelo, Peterson, Wilbur, & Reinhold, 2017). In this particular case study it is important to take into consideration the factors that could be contributing to the nausea, vomiting, and diarrhea in patient HL. The patient has a history of drug abuse. With that being said, drug withdrawal can be a factor in the cause of nausea, vomiting, and diarrhea. Treatment for this type of cause would be dependent on what type of drug that patient was withdrawing from. The next factor would be medications the patient is currently taking. All three of these medications have nausea and vomiting as potential side effects. If this is the cause of the patient’s chief complaint, changing the medications could be an appropriate response. The last consideration would be the patient’s diagnosis of possible Hepatitis C. The most common symptoms of Hepatitis C include nausea, vomiting, and diarrhea (Franciscus, 2015). It would be hard to diagnose the cause of this episode of nausea, vomiting, without other information such as aggravating and relieving factors, how long these symptoms have been occurring, and if any other symptoms are associated with these. First-line treatment of nausea and vomiting includes phenothiazines such as promethazine. Promethazine can be given in 12.5-25 mg every four to six hours as needed. Contraindications include hypersensitivity, seizure disorders, and Parkinson’s disease. Adverse effects include sedation, agitation, dry mouth, and blurred vision (Arcangelo, Peterson, Wilbur, & Reinhold, 2017). Second-line therapy would be to add an antihistamine or anticholinergic such as diphenhydramine. This medication is dosed from 25-50 mg every six to eight hours as needed. Adverse effects include drowsiness, confusion, and dry mouth. Contraindications include asthma, hypersensitivity, and narrow-angle glaucoma (Arcangelo, Peterson, Wilbur, & Reinhold, 2017). If symptoms persist, the patient needs to reevaluate for other causes. Alternative therapies, including herbal therapies such as vitamin B6, ginger, and even gum chewing, are linked to the relief of nausea and vomiting (Darvall, Handscombe, & Leslie, n.d.).

Diagnosis and Rationale

The primary suspicion for patient HL's presentation of nausea, vomiting, and diarrhea involves a multifactorial etiology, primarily focused on drug-induced effects, withdrawal symptoms, and underlying hepatitis C. Given the patient's history of drug abuse, withdrawal from substances such as opioids or other central nervous system depressants could explain nausea and vomiting. Such symptoms are characteristic of withdrawal syndromes, especially in individuals who may not have recent access to their usual substances (Gowing et al., 2017). Additionally, HL's current medications—nifedipine, prednisone, and synthroid—are associated with gastrointestinal side effects, including nausea, vomiting, and diarrhea, which complicate pinpointing the exact cause.

Another consideration is hepatitis C infection, which often presents with constitutional symptoms like nausea, fatigue, and gastrointestinal disturbances (American Liver Foundation, 2020). Though hepatitis C is usually insidious and chronic, acute exacerbations or related hepatic dysfunction may precipitate gastrointestinal symptoms. Liver impairment can impair detoxification and metabolic processes, leading to symptoms like nausea and diarrhea (Nelson et al., 2020).

Because drug withdrawal symptoms and medication side effects are plausible, a comprehensive assessment including recent medication changes, duration of symptoms, and laboratory studies (liver function tests, hepatitis C viral load) is essential. Nonetheless, the differential diagnosis points to probable drug withdrawal and medication side effects, with underlying hepatitis C possibly exacerbating these symptoms.

Drug Therapy Plan and Justification

The primary focus of treatment involves managing the patient's nausea and vomiting while addressing the underlying causes. Pharmacologically, first-line antiemetic agents such as promethazine (a phenothiazine) are recommended, given their efficacy in controlling nausea associated with various systemic illnesses and withdrawal syndromes (Arcangelo et al., 2017). Promethazine, administered in doses of 12.5-25 mg every 4-6 hours as needed, provides rapid relief. However, contraindications like hypersensitivity, seizure disorders, and Parkinson’s disease must be carefully evaluated before prescription.

As a second-line agent, diphenhydramine (25-50 mg every 6-8 hours as needed) serves as an antihistamine-antiemetic option with sedative properties beneficial in controlling symptoms. Its anticholinergic effects help reduce nausea but warrant caution in patients with narrow-angle glaucoma, asthma, or hypersensitivity (Arcangelo et al., 2017).

Supportive herbal therapies, such as ginger and vitamin B6, have shown benefits in reducing nausea and are safe adjuncts, especially in cases where pharmacologic intervention is insufficient or contraindicated (Darvall et al., n.d.). Additionally, non-pharmacologic strategies such as ginger capsules or gum chewing could complement medication therapy by calming gastric motion.

Addressing the underlying causes involves counseling about potential withdrawal symptoms, adjusting or temporarily discontinuing medications with significant gastrointestinal side effects if appropriate, and treating hepatitis C as part of a long-term management plan. Initiating or optimizing antiviral therapy for hepatitis C (e.g., direct-acting antivirals) could reduce systemic symptoms and improve hepatic health (Nelson et al., 2020).

Justification for Therapy

This pharmacotherapy plan aligns with current evidence-based guidelines emphasizing the use of promethazine as first-line for nausea, considering its proven efficacy and rapid action (Arcangelo et al., 2017). Diphenhydramine offers an alternative or adjunct, particularly if allergic or sedative side effects are desirable. Herbal therapies such as ginger and vitamin B6 are supported by clinical trials for nausea relief, came with minimal risks, and can enhance symptom control without added pharmacologic burden (Gordon et al., 2020).

Furthermore, addressing hepatitis C through antiviral therapy not only reduces hepatic-related symptoms but also prevents the progression to cirrhosis or hepatocellular carcinoma, ultimately improving overall health outcomes (Nelson et al., 2020). Consequently, this comprehensive approach integrates symptom management with long-term disease control, ensuring targeted and individualized patient care.
