The items below are important to know. Drug (Also known as: Medication) Full De昀椀nition: Any chemical that can a昀昀ect living processes within the human body (Burchum & Rosenthal, 2019).Note: The term drug and medication can and will be used interchangeably throughout this course. Simple De昀椀nition: Any substance that has a physiological e昀昀ect on the body Pharmacology Full De昀椀nition: The study of drugs and their origin, nature, properties, and e昀昀ects on living organisms (Venes, 2013). Simple De昀椀nition: The study of drugs and their e昀昀ects on the body Therapeutics (Also known as: Pharmacotherapeutics) Full De昀椀nition: The use of drugs to diagnose, prevent, or treat disease.Note: The phrase "therapeutic e昀昀ect" refers to the drug's e昀昀ect on the body to diagnose, prevent, or treat disease (Burchum & Rosenthal, 2019). Simple De昀椀nition: Bene昀椀cial or useful e昀昀ects of a drug Side e昀昀ect Full De昀椀nition: Responses in the body where the drug's e昀昀ects are neither needed nor wanted that cause problematic, but not harmful, symptoms (Smith, 2016). Simple De昀椀nition: Undesirable e昀昀ects that are bothersome, but not harmful to the client Adverse e昀昀ect Full De昀椀nition: Responses in the body where the drug's e昀昀ects are both undesirable and harmful (Smith, 2016). Simple De昀椀nition: Harmful undesirable e昀昀ects Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 Pharmacokinetics Full De昀椀nition: The study of the metabolism and action of drugs with particular emphasis on the time required for absorption, duration of action, distribution in the body, and method of excretion (Venes, 2013). Simple De昀椀nition: What the body does to drugs Pharmacodynamics Full De昀椀nition: The molecular interactions of a drug with speci昀椀c biological receptors on or in the body's cells, which lead to a desired therapeutic response (Smith, 2016). Simple De昀椀nition: What drugs do to the body The Original 5 Rights For much of nursing's history, nursing medication administration focused on the "5 rights". These 5 rights are almost as old as the profession of nursing, and are often referred to colloquially as "The Rights". 1. Give the right drug 2. ...to the right client 3. ...in the right dose 4. ...by the right route 5. ...at the right time. In recent years however, the original 5 rights have been expanded upon; some textbooks refer to 6, 7, 8 or even 10 unique rights. Common examples of additional rights include: Right assessment Right documentation Right evaluation The client's right to education The client's right of refusal Limitations of the rights While The Rights are an essential and critical element to safe and e昀昀ective medication administration, they fail to encompass the totality of the nurse's responsibilities around medication administration. Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 The Rights only ensure that the medication will be administered as prescribed. As future professional nurses, it is imperative that you practice to the fullest extent of your education and training. This means you will need to begin thinking of medication administration as much more than simply The Rights. You must recognize that important additional interventions are required both before and after a medication is given to ensure it will do the most good with the least harm. An in-depth understanding of pharmacology is therefore required of the modern professional nurse in order to ensure the overall therapeutic goals are accomplished for your client. Checks and Balances Remember that The Rights only ensure that the medication is given as prescribed. But what if a mistake was made by the pharmacist or the prescribing clinician. Strict adherence to The Rights is important, but it is not going to prevent a mistake from reaching the client. Does that mean the nurse has no responsibility in preventing mistakes? The answer is NO - nurses indeed, have a responsibility to detect and prevent upstream errors from reaching the client. Nurses spend the most time directly with the client, and therefore often know the client's health status best. The closeness of this nurse-client relationship allows the nurse to: observe how the medication is a昀昀ecting the client and intervene if needed. anticipate how a particular medication and or dosage will a昀昀ect the client if given. The nurse is the last line of defense against medication errors. Applying your Pharmacology Knowledge A good way to break down the responsibilities of the nurse as it pertains to pharmacology is to think about it in the two primary spheres of in昀氀uence the nurse has related to medications: 1. Pharmacology knowledge as it pertains to the direct client care you provide 2. Pharmacology knowledge as it pertains to client education Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 Pharmacology Knowledge: Direct Client Care The use of pharmacology in client care focuses on the following eight aspects of medication therapy: 1. Preadministration assessment - Collecting data and analyzing that data 2. Dosage and administration - The Rights 3. Promoting therapeutic e昀昀ects - Examples, using an analgesic with nonpharm comfort measures; using asthma meds with breathing exercises 4. Minimizing adverse e昀昀ects - This requires knowledge of what to look for and how to intervene 5. Minimizing adverse interactions - This requires knowledge of how di昀昀erent drugs interact with each other when given concurrently to the same client 6. Making “as needed” or PRN decisions - This requires good nursing judgement 7. Evaluating responses to medications - Is the drug doing what it was supposed to, is not e昀昀ective, or is causing having harmful adverse e昀昀ects 8. Managing toxicity - This requires knowledge The common thread throughout all these aspects is "you could never know too much about the medications you are giving your clients". Pharmacology Knowledge: Client Education Nurses play an important role in educating clients about their medications. When educating clients, it is important to give the client the following information: 1. 2. 3. 4. The name of the drug and what it is for in simple terms Dosage - how much to take with each dose Dosing schedule - how often to take it Route and technique of administration - PO versus sublingual versus subcutaneous 5. What the expected response should be an when they should expect it 6. Nondrug measures to enhance their response (e.g. exercise for hypertension) 7. Duration of the treatment 8. How to store it 9. Symptoms of major adverse e昀昀ect and how to cope with them 10. Major drug-drug and drug-food interactions 11.

Levodopa, Carbidopa 3,345 views Summary Levodopa and carbidopa are medications given in combination to treat Parkinson’s disease. Levodopa can cross the blood brain barrier to enter the brain, where it is converted into dopamine. Carbidopa on the other hand, is given along with levodopa to help more levodopa reach the brain. This drug combination is very e昀昀ective in treating the symptoms of Parkinson's disease. Side e昀昀ects include psychiatric disturbances and orthostatic hypotension. Levodopa and carbidopa must not be stopped suddenly, or a paralysis known as akinetic crisis can occur. Instead, the patient should taper o昀昀 the drug slowly. Key Points o Levodopa, Carbidopa o Mechanism o Dopaminergic drug combination o Levodopa is converted to dopamine in the brain, and carbidopa is added to increase the amount of Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 o o dopamine that reaches the brain. Without carbidopa, 99% of levodopa gets converted into dopamine before it reaches the brain and requires a really large dose to be e昀昀ective, causing severe side e昀昀ects. Carbidopa allows for a smaller dose of levodopa with higher e昀昀ectiveness. o Has a short half-life and must be taken 3-4 times per day Clinical Use o Parkinson Disease o Helps with bradykinesia and tremors o Full therapeutic e昀昀ect may take up to 6 months Side E昀昀ects and Adverse Reactions o Orthostatic hypotension o Expected side e昀昀ect o Instruct patient to rise slowly o Akinetic crisis if stopped suddenly o Complete loss of movement o Can present if levodopa/carbidopa is stopped suddenly.

The exception to this rule is methylphenidate, which is an amphetamine-like drug that works similarly, but has a lower abuse potential. Amphetamines are CNS stimulants clinically used to treat ADHD and narcolepsy. Amphetamines can cause insomnia, so be sure to give the last dose before 6:00 pm to avoid interfering with nighttime sleep. Amphetamines can also cause hypertension and tachycardia, so the patient’s vital signs should be monitored closely. Other side e昀昀ects of amphetamines include appetite suppression, leading to weight loss and growth suppression. As the nurse, be sure to closely monitor the patient’s height and weight, especially in children. And lastly, keep in mind that amphetamines can cause tolerance and dependence, leading to a high abuse potential. Key Points o Key Drugs o End in “-amphetamine” o Amphetamine o Dextroamphetamine o Methamphetamine o Methylphenidate (Ritalin, Concerta) o Is an amphetamine-like drug, meaning it acts in a similar mechanism but has a lower potential for abuse and tolerance than amphetamines o Mechanism Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 CNS Stimulant o Increases neurotransmitters dopamine and norepinephrine in the brain by inhibiting their reuptake Clinical Use o Attention De昀椀cit Hyperactivity Disorder (ADHD) o First line agent for treating ADHD o Increases attention span, decreases distractibility o Narcolepsy o Corrects abnormal sleep patterns Side E昀昀ects and Adverse Reactions o Side e昀昀ects may be more severe if taken with other stimulants like ca昀昀eine o Hypertension o Related to stimulant e昀昀ect of increasing norepinephrine and dopamine signalling o Closely monitor patient’s blood pressure o Use with caution in patients with hypertension o Taking with MAOIs can result in a hypertensive crisis o Tachycardia o Increased HR is a stimulant e昀昀ect o Dysrhythmias and angina may be seen o Insomnia o Related to stimulant (amphetamine-like) e昀昀ects o Administer the last dose before 6:00 pm to avoid interference with sleep o Decreased appetite & weight loss, growth suppression o Closely monitor height and weight, especially in children o Methylphenidate is usually given 2-3 times a day before meals, but timing may be adjusted after consulting with provider if the child isn’t eating enough o Abuse potential o Tolerance / dependence o o o Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 Module THREE: Chlorpromazine - Traditional Antipsychotics (low-potency) Haloperidol - Traditional Antipsychotics (high-potency) Clozapine - Atypical Antipsychotics Fluoxetine - Selective Serotonin Reuptake Inhibitors Venlafaxine - Serotonin/Norepinephrine Reuptake Inhibitors Imipramine - Tricyclic Antidepressants Phenelzine - Monoamine Oxidase Inhibitors Bupropion - Atypical Antidepressants Lithium - Mood Stabilizers Valproic acid - Mood Stabilizers Carbamazepine - Mood Stabilizers Triazolam - Benzodiazepines Zolpidem - Benzodiazepine-like Drugs Buspirone - Nonbenzodiazepine-Nonbarbiturates Typical Antipsychotics 3,004 views Summary Typical antipsychotics are a class of drugs that include haloperidol and 昀氀uphenazine. As their name suggests, the typical antipsychotics are used to treat psychosis and psychotic disorders like schizophrenia, as well as dangerous agitation and aggression. Side e昀昀ects include extrapyramidal symptoms, abbreviated EPS, neuroleptic malignant syndrome, abbreviated NMS, drowsiness or sedation, anticholinergic e昀昀ects, and a prolonged QT interval that puts the patient at risk for torsade de pointes.

Drugs in this category include clozapine, olanzapine, aripiprazole, risperidone, quetiapine, and ziprasidone. Side e昀昀ects of these drugs include extrapyramidal symptoms, abbreviated EPS, which refers to a constellation of movement problems, like tremors, muscle spasms, and restlessness. Atypical antipsychotics are also well known for causing metabolic syndrome and weight gain. Other side e昀昀ects include sedation, anticholinergic e昀昀ects, and neuroleptic malignant syndrome, abbreviated NMS. NMS is a medical emergency characterized by muscle rigidity, fever, confusion, and unstable vitals. Clozapine can cause agranulocytosis, or a rapid fall in white blood cells, and ziprasidone can cause QT prolongation and the abnormal heart rhythm of torsades de pointes.

SNRIs are useful in treating depression, anxiety, and chronic pain. Notably, SNRIs have the potential to cause serotonin syndrome, a life-threatening medical emergency. As a reminder, with serotonin syndrome the body is experiencing overactive everything - tachycardia, hypertension, hyperactive re昀氀exes, diarrhea, and so on. This risk for serotonin syndrome is increased if SNRIs are combined with any other serotonin-altering substances, like St. John’s Wort or MAOIs. SNRIs can also cause sexual dysfunction.

These drugs are used to treat depression, although they are not 昀椀rst-line treatments due to their side e昀昀ects and dangerous food and drug interactions. Notably, MAOIs can cause a hypertensive crisis, especially if patients consume foods containing tyramine, like wine, cheese, and processed meats. MAOIs can also cause serotonin syndrome, a lifethreatening condition resulting from overload of serotonin signaling.

It has a narrow therapeutic range, and toxicity symptoms start to show up above a blood level of 1.5. Things that can cause lithium toxicity include 昀氀uid loss like dehydration and diuretics, low sodium levels, decreased kidney function, or the speci昀椀c use of NSAIDs or thiazide diuretics. Early signs of lithium toxicity include GI distress, which includes nausea, vomiting, and diarrhea. Late signs of toxicity are neurological problems, like loss of coordination, sedation, confusion, or seizures. Lithium is also teratogenic and should not be given during pregnancy.

Benzodiazepines are central nervous system depressants, meaning they slow the brain down and reduce brain Downloaded by alice Thompson (alicethompson140@yahoo.com) lOMoARcPSD|47509962 activity. This is helpful in treating anxiety, treating seizures, as well as treating the symptoms of alcohol withdrawal. Benzodiazepines cause sedation, to the point where some benzodiazepines may even be used to treat insomnia. Benzodiazepines can also cause respiratory depression, if taken in excess or if taken with other CNS depressants like alcohol or opioids. Benzodiazepines can cause tolerance and dependence, and if possible, the drug should be tapered down slowly to avoid withdrawal symptoms. If respiratory depression or other toxic e昀昀ects of benzodiazepines do occur, 昀氀umazenil is the antidote used and can reverse the e昀昀ects of benzodiazepines.

It is a short-term treatment, and should not be used for longer than 10 days. Zolpidem is a preferred treatment for insomnia over benzodiazepines because it does not have as high of a risk for dependence or abuse compared to the benzodiazepine drugs.
