Sample Answer for NURS 6521 COMPARING AND CONTRASTING PHARMACOLOGIC OPTIONS FOR THE TREATMENT OF GENERALIZED ANXIETY DISORDER 

Generalized anxiety disorder (GAD), a chronic condition, frequently starts in adolescence or the early stages of adulthood and lasts the rest of one’s life (Strawn et al., 2018). The medications include selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). These are Antianxiolytics, which typically affect the brain’s neurotransmitters inhabiting reuptakes in terms of their pharmacokinetics and pharmacodynamics.  

Selective Serotonin Reuptake Inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs) are considered the first line of drugs to treat generalized anxiety disorder. The main mechanism of action of SSRIs is to prevent presynaptic serotonin reuptake at the serotonin transporter, which raises serotonin levels at the postsynaptic membrane in the serotonergic synapse (Edinoff et al., 2021). These medications include fluoxetine, Citalopram, escitalopram, paroxetine, sertraline, and fluvoxamine. These medications treat generalized anxiety disorder using the same mechanism. However, each of them has unique pharmacokinetics and pharmacodynamics. The half-life of each drug varies, for instance, fluoxetine’s half-life is 1 to 4 days, whereas Citalopram’s half-life is 26 hours. SSRIs tend to be metabolized by cytochrome P450 in the liver. SSRIs tend to have better specificity than MAOIs and TCAs, which makes them the drug of choice for treating depression as well. The side effects of these medications include weight gain, sleepiness, and dry mouth. 

Different Treatment Options:  

Antihistamines, such as Hydroxyzine are one of the most common FDA-approved medications that could be used for anxiety as well. Antihistamines, such as hydroxyzine, are histamine-1 receptor (H1) blockers that are frequently used as an alternative to benzodiazepines for anxiety, panic attacks, and sleeplessness (Garakani et al., 2020). Though antihistamines are used for allergy symptoms, Hydroxyzine and Diphenhydramine (Benadryl) may be safer for adolescents and in pregnancy for anxiety symptoms as well. Aside from side effects including dry mouth, constipation, and sedation, antihistamines are generally well tolerated. 

Cannabis may have potential therapeutic effects in treating anxiety. Cannabis is known for its pleasurable and calming effects. Additionally, preclinical studies show that CBD has antidepressant effects after both acute and long-term dosing (Martin et al., 2021). The use of cannabis and other cannabinoids is accepted as a safe means of promoting relaxation and reducing anxiety, however there is not much literature or evidence that supports that.  

Benzodiazepines are one the treatment for anxiety and remain one of the most commonly used classes of psychiatric drugs worldwide. Benzodiazepines, which function as GABA-A agonists, are very adaptable drugs that can be administered for a variety of disorders. They can be used for mania, insomnia, anxiety, agitation, and seizures. However, antidepressant effectiveness may be decreased by long-term usage of benzodiazepines to treat anxiety and co-morbid depression (Garakani et al., 2020).

Sample Answer 2 for NURS 6521 COMPARING AND CONTRASTING PHARMACOLOGIC OPTIONS FOR THE TREATMENT OF GENERALIZED ANXIETY DISORDER 

GAD is a chronic condition characterized by uncontrollable worrying. (Rosenthal 2018, p.243). Most patients with GAD also have another psychiatric disorder, depression.  It usually involves a persistent feeling of anxiety or dread that interferes with how you live your life. “It is not the same as occasionally worrying about things or experiencing anxiety due to stressful life events. People living with GAD experience frequent anxiety for months, if not years. GAD develops slowly. It often starts around age 30, although it can occur in childhood. The disorder is more common in women than in men.” (NIH of Mental Health). Good news, it’s treatable. SSRIs and SNRIs are the first line treatment for GAD.  

Of the 13 benzodiazepines available, 6 are approved for anxiety. Benzodiazepines are second-line drugs for anxiety called central nervous system depressants. “They raise levels of an amino acid in your brain called gamma-aminobutyric acid (GABA). blocks other activity in your brain, which helps you feel calm and can make you sleepy. Anxiolytic effects develop slowly with first initial responses to show within a week.They are distinguished by their pharmacokinetics and their metabolism to a large extent; condition their use [3]. These are weak acids of variable constant dissociation with a high lipophilicity, which allows rapid passage through the membranes (blood-brain and placental barriers, and passage in breast milk). ” (Bourin, 2018). 

Pregabalin can be used for epilepsy and neuropathy pain, as well as GAD. Pregabalin exerts its anxiolytic effects by potently binding to the alpha2-delta subunit of the voltage-gated N-and P/Q-type calcium channels in central nervous system (CNS) tissue. This causes a decrease in presynaptic calcium currents which modulates the release of neurotransmitters, including glutamate, substance P, and calcitonin gene-related peptide from excited neurons. A decrease in scores on the Hamilton Anxiety Rating Scale was noted with pregabalin within a week and was effective on both somatic and psychic symptoms; shown to be effective in patients over 65 years of age.

Sample Answer 3 for NURS 6521 COMPARING AND CONTRASTING PHARMACOLOGIC OPTIONS FOR THE TREATMENT OF GENERALIZED ANXIETY DISORDER 

Anxiety is a type of medical condition whereby the person feels worried, uneasy, nervous, or stressed. According to the American Psychiatric Association, anxiety is defined as an emotion characterized by feelings of tension, worried thoughts, and physical changes like increased blood pressure. The Diagnostic and Statistical Manual of Mental Health Disorders (DSM-V) classifies anxiety disorders into several main types such as generalized anxiety disorder, panic anxiety, and selective mutism. 

Generalized anxiety disorder (GAD) is a type of anxiety that makes a person feel constantly worried. These worrying feelings are about anything and they can last for more than six months. Other symptoms of GAD include nausea, fatigue, trembling, urinating often, sweating hot flashes, irritability, and trouble breathing (Andrews et al., 2010). People diagnosed with GAD are subjected to psychotherapy and medical treatment. The medications used to treat GAD are classified as anxiolytic medications which are a group of drugs used to prevent or treat anxiety symptoms or disorders. They are sometimes called anti-anxiety medications or minor tranquilizers. Anxiolytic medications are habit-forming and can lead to dependency or a substance use disorder. For this reason, they’re often only prescribed for a short amount of time. Some of the anxiolytic medications include SSRIs (sertraline, fluoxetine, paroxetine, and citalopram). Selective serotonin-norepinephrine reuptake inhibitors (SNRI) such as Venlafaxine and Duloxetine have been approved by FDA as a treatment for GAD. Benzodiazepines (alprazolam) and other types of anxiolytic medications such as Second-generation antipsychotics (SGAs). 

    Before prescribing these drugs to any patient, it is important to understand their pharmacokinetics and pharmacodynamics. For example, the pharmacokinetics and pharmacodynamics of benzodiazepines involve the increase of g-aminobutyric acid (GABA) inhibitory impulses in the central nervous system mediated via benzodiazepine receptors. GABA blocks other activity in your brain, which helps you feel calm and can make you sleepy.  

 The structure of benzodiazepines is made up of a benzene ring fused to a seven-membered 1,4 diazepine ring. Alprazolam is administered orally and is directly metabolized by hepatic microsomal oxidation (Jahn et al., 2016). They have a peak plasma concentration which occurs after 1 to 2 hours of being taken. Another drug is chlordiazepoxide which although itself has an intermediate half-life (6 — 28 h), its active metabolite desmethyldiazepam has a very long half-life; oral chlordiazepoxide is rapidly and completely absorbed and its volume of distribution varies from 0.25 to 0.50 l/kg. The drug seems to block electroencephalogram arousal from stimulation in the brain stem reticular formation. 

            Another type of anxiolytic drug that has been approved to treat GAD is the Selective serotonin reuptake inhibitor (SSRI) drug that works by inhibiting serotonin reuptake transporter and this inhibition of the 5-HT increases the concentration of synaptic hence increasing the extra-synaptic diffusion. An example of SSRIs is fluoxetine which is metabolized through the CYP2D6 system, inhibits CYP2D6 activity, and exhibits considerable intra-individual variability in tolerability and response (Strawn et al., 2018). It also has noradrenergic and dopaminergic effects which putatively underlie its therapeutic efficacy. SNRI is another type of anxiolytic drug used for treating GAD. An example of SNRI such as venlafaxine has been approved by Food Drug Administration to treat GAD. The pharmacokinetics and pharmacodynamics of venlafaxine work through active metabolite, o-desmethylvenlafaxine by inhibiting the serotonin and norepinephrine reuptake transporters albeit with greater potency at the norepinephrine transporter (Gravelle, 2016). Duloxetine has been approved by the FDA to treat GAD. Its pharmacodynamics and pharmacokinetics include the reuptake inhibition of serotonin and norepinephrine at the presynaptic neuron in Onuf’s nucleus of the sacral spinal cord ( ). 

            Another group of anxiolytic medications used is Non-benzodiazepine Sedative-Hypnotics such as eszopiclone which works by interaction with GABA receptor complexes at binding domains located close to or allosterically coupled to benzodiazepine receptors. Other types of anxiolytic medications are Second-generation antipsychotics (SGAs), Antihistamines, GABA-related interventions, and Tricyclic Antidepressants. 

   In conclusion, the choice of anxiolytic drug to be prescribed is dependent on the pharmacokinetics and pharmacodynamics factors that might affect the efficacy of the drug. It has been observed that SSRIs and SNRIs are considered the most effective while benzodiazepine and other types of drugs come second. An expert opinion argues that there is a need for healthcare providers to take an optimal pharmacological approach towards integrative pharmacokinetic and pharmacodynamics optimization strategy that would ensure better treatment and personalization of anxiety disorders. According to Almatura et al. (2013), this approach would help in the development of new anxiolytic drugs that are more effective and have limited side, especially benzodiazepines drugs.

Hello Ruth! This is an in-depth discussion post. Indeed, the treatment of GAD entails both psychotherapy and pharmacotherapy. Essentially, multimodal approaches involving psychotherapy and pharmacotherapy in the management of GAD may distinctively focus on specific symptoms and the inclusion of psychotherapy enhances compliance with treatment and reduces reported adverse effects of pharmacotherapy. Understanding the principles of pharmacokinetics and Pharmacodynamics in the management of GAD is critical in the helping healthcare professionals to make informed decisions about medication formulation and dosage needs (Abuhelwa et al., 2022). It also crucial in building treatment plans entailing medications. The other potential treatment option in this case is psychotherapy. This options involves psychological counseling or talk therapy (Lamb et al., 2019). Here, a patient is expected to work with a therapist to minimize the anxiety symptoms. The popular form of psychotherapy for GAD is cognitive behavioral therapy (CBT). Psychotherapy is CBT aims at teaching particular skills to directly control the patent’s worries and help the patient to slowly return to that had been previously avoided due to anxiety.

Sample Answer 5 for NURS 6521 COMPARING AND CONTRASTING PHARMACOLOGIC OPTIONS FOR THE TREATMENT OF GENERALIZED ANXIETY DISORDER

Summary of Patient Case Study 

A 71-year-old Asian man with a history of GAD, which was caused by diabetes and hypertension, was presented to our inpatient psychiatric clinic. He was mainly brought for stabilization and long-term medication. The information gathered from the family stated that the patient had refused oral food intake for about thirty hours, was isolative in his room, and had increased confusion. The diagnosis also showed a history of GAD in the patient’s family, especially among aged people. After admitting him to our clinic, the clinical presentation of the patient depicted a transformed level of consciousness. I took three imperative decisions I thought could help him. They include: stabilizing him, performing psychotherapy, and administering relevant medication. 

Evaluation of My Decisions 

I believe the decisions I provided were supported by evidence-based literature. According to Watts et al. (2020), psychotherapy involves working with therapists to reduce the level of GAD. For example, in our case, I recommended the therapist to use behavioral therapy because it was the most effective psychotherapy for GAD. On the other hand, stabilizing the patient is imperative because it ensures the conditions of the patient are within the healthy range (Savioli et al., 2020). For example, in our case, I recommended calming the patient to regain his level of consciousness.  Lastly, I recommended the patient’s medication because it could ease symptoms and prevent or halt hypertension and diabetic conditions (Wilhelmsen& Eriksson, 2019). Medication was the heart of everything because the patient’s issues were beyond anxiety disorders. 

Objectives of My Decisions 

First, I hoped behavioral therapy could help the patient manage various GAD-related symptoms, such as anxiety and stress. I also expected this treatment option could help the patient cope with negative emotions. Second, I hoped the medication decisions I recommended, such as Crestor 20mg daily, Lantus insulin 10 units daily, Metformin 70mg daily, Lithium 300mg daily, and hydrochlorothiazide 25mg daily, could help the patient improve his hypertension and diabetic conditions. Lastly, I hoped the patient would be stable after recommending a stabilization program in the emergency room. I also expected his pressure to normalize after calming him by providing personal attention. 

 Differences between Expectations and Results 

In psychotherapy, the expected results were attained. For example, the patient coped with adverse emotions and managed his anxiety and stress. He calmed down and started conversing with me. On the other hand, the prescribed medication also responded positively as planned. For example, in this decision, I aimed to improve the patient’s diabetic condition, which came down to manageable levels. Therefore, there was no difference between the anticipated and results. Lastly, the objectives of my decision to stabilize the patient aligned with the outcomes. For example, the patient’s hypertension was very high, but I managed to bring it to normal levels. 

Pharmacokinetics and Pharmacodynamics Processes 

In the pharmacokinetics process, the medication I recommended, especially oral medication, undergoes three stages. Absorption is the first stage, where the medicine is ingested and passed through the stomach into the intestine linings. The second stage is distribution, where the drugs pass through the liver and intestines into the bloodstream. The third stage is metabolism, where the drug undergoes glucuronidation and oxidation. The last stage is the excretion of the medicine, mainly through the functioning of the kidney. The pharmacodynamics commences when the drug reaches the target organ or tissue. The drug may involve enzyme inhibition or cause presynaptic or postsynaptic effects on the patient. The final part of pharmacodynamics involves cellular response and signal transduction.

Hello Brandy! This is an outstanding discussion post. Indeed, psychotherapy therapy is essential in helping the patient manage various GAD-related symptoms, such as anxiety and stress and also help the patient cope with negative emotions (Lamb et al., 2019). Understanding the pharmacokinetics and Pharmacodynamics in the management of GAD in this case is important. When prescribing medications to this patient, the ultimate goal is to achieve a therapeutic outcome and while reducing adverse effects. A proper understanding of critical pharmacokinetic and pharmacodynamic properties of the medications is critical in formulating treatment plans entailing medications and also optimizing its utility in patients and supporting the medication development initiative (Abuhelwa et al., 2022). It is important to involve interprofessional team to ensure the safety and efficacy of pharmacokinetic and pharmacotherapy. The patient should be educated on correct self-administration and storage of medications. This education can be conducted by the nurse, pharmacist, or physician.

Sample Answer 7 for NURS 6521 COMPARING AND CONTRASTING PHARMACOLOGIC OPTIONS FOR THE TREATMENT OF GENERALIZED ANXIETY DISORDER 

Thank you for a great post on Generalized Anxiety Disorder (GAD) and its treatment options, including the mention of cannabis as a potential treatment. The use of cannabis as a possible treatment for GAD is a subject of interest, but its effectiveness and safety are complex. Cannabis comprises compounds, such as THC, that can induce anxiolytic and anxiogenic effects, varying outcomes among individuals based on strain, dosage, and personal tolerance (de Manincor et al., 2020). Individuals with GAD must exercise caution when considering cannabis as a treatment, as its effects can differ widely and have the potential for abuse. While some may experience temporary relief, others may witness heightened anxiety or even panic attacks (Stoner, 2017). Moreover, prolonged or excessive cannabis use can exacerbate anxiety and lead to other mental health issues.  

A notable concern is the limited research on the long-term effects and safety of cannabis as a GAD treatment (Legare et al., 2022). Healthcare providers typically prefer evidence-based treatments, and the current body of research is insufficient to firmly support cannabis as a primary GAD treatment. In contrast, the mental health field offers a range of evidence-based therapies, such as Cognitive Behavioral Therapy (CBT), which have demonstrated effectiveness in GAD treatment (Cameron et al., 2022). These therapies equip individuals with valuable skills and strategies to manage anxiety without the potential risks associated with cannabis.  

Individuals experiencing GAD are strongly advised to seek consultation with healthcare professionals to determine the most suitable treatment for their specific condition (National Institute for Health and Care Excellence, 2019). Healthcare providers can advise on available treatment options, potential side effects, and which treatments align best with individual needs. Given that anxiety disorders, including GAD, can manifest differently from person to person, a personalized approach to treatment is crucial. What works for one individual may not be effective for another. Thus, close collaboration with a healthcare provider is essential to identify the most effective and safe treatment plan. In summary, the use of cannabis for GAD is a multifaceted issue that necessitates caution and professional guidance. Evidence-based treatments, like psychotherapy and medications, remain the primary and more established approaches for managing GAD, with a proven track record in effectively addressing this condition.

Sample Answer 8 for NURS 6521 COMPARING AND CONTRASTING PHARMACOLOGIC OPTIONS FOR THE TREATMENT OF GENERALIZED ANXIETY DISORDER 

Anxiolytics are a group of drugs used in the treatment of generalized anxiety disorder. The different anxiolytics utilized include benzodiazepines, buspirone, anticonvulsants, antihistamines, and beta-adrenergic blockers. Benzodiazepines are the most commonly used drugs for GAD because of their high safety, efficacy, and acceptance level by the patients. The example of drugs in this class includes diazepam, oxazolam, nitrazepam, estazolam, and medazepam among others. The drugs work by increasing gama-aminobutyric acid in the central nervous system, which reduces anxiety levels. The plasma concentration of benzodiazepine is directly proportional to their concentration at the receptor sites. Their effects are also directly proportional to their plasma concentration at a level above the minimal effective concentration. Benzodiazepines have high protein binding with the drugs being 95% distributed in the body once distribution equilibrium has been achieved (Bounds & Nelson, 2023; Tucker, 2022). The routes of administration include intravenous, intramuscular, and oral. Benzodiazepines are metabolized in liver and excreted via the kidneys.

Anticonvulsants are also used for treating GAD. They also work by increasing the levels of gama-aminobutyric acid in the central nervous system. Pregabalin and Gapabentin are the most commonly used anticonvulsants, which are taken orally, with linear absorption and bioavailability dependent on the dose. Anticonvulsants are metabolized in the liver and excreted via the renal system. Buspirone is the other drug, which is an azapirone piperazine compound that moderates receptor affinity for dopamine and 5-HT1A receptor agonist. Buspirone is largely used for mild to moderate GAD. Its effects take weeks to be realized. Buspirone is administered orally, metabolized in the liver, and excreted in the kidneys (Skidmore-Roth, 2022). It has high drug interactions with tricyclic antidepressants, cimetidine, haloperidol, and benzodiazepines.

Beta-adrenergic drugs are the other class that works by inhibiting the actions of adrenaline and noradrenaline from acting on the beta adrenergic receptors in the sympathetic nervous system. They are administered orally, metabolized in the liver, and excreted through urine. The last category of drugs is antihistamines, which induce sleep and produce calmness in patients with GAD.  They are administered orally, metabolized in liver, and excreted through the kidneys (Williams, 2022). Antihistamines are less effective as compared to benzodiazepines in the treatment of moderate and severe GAD.
