Less common events that have been reported include arrhythmia atarax 25mg lowest price anxiety symptoms related to menopause, bradycardia purchase 10 mg atarax with mastercard anxiety zen youtube, vomiting cheap 25mg atarax fast delivery anxiety 0 technique, extrapyramidal effects and pruritus (14 purchase atarax 10mg anxiety symptoms when not feeling anxious, 15, 23, 24). Eye disorders, varying in type and severity have been reported, including transient accommodation disorders and corneal opacifcation, which regressed once treatment was stopped, and, very rarely, irreversible retinopathy (3). It is important that parents or guardians continue to use other malaria prevention measures (such as insecticide-treated bednets) and monitor their children; they should seek medical attention immediately in the event of febrile illness. Cardiovascular effects have been reported during high-dose treatment with other 4-aminoquinoline derivatives. There is no evidence, however, that an overdose of amodiaquine causes any of the life-threatening cardiovascular complications seen with overdose of chloroquine. Caution should nevertheless be exercised in treating patients who have recently taken another antimalarial drug with cardiovascular side-effects, such as quinine or mefoquine. Pragmatic dosing Fixed dose artesunate + amodiaquine result in better treatment effcacy than loose tablets (29). Antimalarial dosing has often been based on age because access to formal health services or functioning weighing scales is often limited in malaria- endemic countries. While age-based dosing is more practical, it carries a risk for potential under- or over-dosing of more patients. Large datasets of weight-for-age have been used to determine suitable age-based dosing for African children (30), which resulted in higher proportions of patients receiving therapeutic doses of A artesunate and amodiaquine. To simplify dosage recommendations in other regions, 5 anthropometric data should be collated for each malaria-endemic region and the data re-modelled accordingly.

Structure and mechanism of action F H3C H3C Artemether is the methyl ether derivative ofH3C F F F dihydroartemisinin. It is two- to threefold less F N O O active than dihydroartemisinin, its active O O C O C O C F O O metabolite. The pharmacokinetics of oral artemether when given in the fxed-dose combination with lumefantrine for the treatment of uncomplicated malaria is shown in section A5. Artemether is a water-insoluble, lipid-soluble compound and is therefore given either as an oil-based intramuscular injection or orally. It is absorbed slowly and erratically after intramuscular administration in severe malaria (Figure A5. While dihydroartemisinin is responsible for most of the antimalarial action after oral administration, the concentrations of artemether parent compound predominate after intramuscular administration in severe A falciparum malaria. Artemether also undergoes auto-induction but to a lesser 5 extent than artemisinin. Both artemether and dihydroartemisinin are eliminated within 7 h of administration (3, 5–10). Individual concentration–time profles for artemether after the frst intramuscular dose of 3. Safety Adverse effects Artemether is generally very well tolerated after both oral and intramuscular administration. It has similar side-effects to other artemisinin derivatives, including hypersensitivity reactions (risk estimate, 1 in 3000), mild gastrointestinal disturbance, dizziness, reticulocytopenia, neutropenia and elevated liver enzyme activity. While studies in experimental animals show neurotoxicity after parenteral artemether, clinical, neurophysiological and pathological studies in humans have not shown similar fndings. Contraindications Artemether is contraindicated in patients with known hypersensitivity to any artemisinin derivative. Cautions A marked increase in the concentration of artemether in the cerebrospinal fuid of patients with meningitis was observed, prompting researchers to advise caution in treating patients with signs of meningitis (2, 10, 11). Patients with acute renal failure have higher maximum concentrations, higher exposure, a lower volume of distribution and a longer elimination half-life of artemether than people without renal failure (6).

Some practitioners are able to naturally commu- nicate with patients more effectively buy 10 mg atarax mastercard anxiety symptoms breathing, whereas others have difficulty communicat- ing with patients due to a variety of reasons 10mg atarax amex anxiety 34 weeks pregnant, including their personality generic atarax 10 mg fast delivery anxiety workbook for teens, comfort level cheap atarax 25 mg free shipping anxiety episodes, and confidence. However, regardless of one’s natural abilities, communica- tion skills and questioning techniques, especially when it comes to communicating with patients, are learned and take time to develop. This chapter examines the most pertinent skills required to conduct a comprehensive medication history. These skills and questioning techniques include: • Active listening • Empathy • Building rapport • Open-ended questions • Closed-ended questions • Leading questions • Silence • “Why” questions • Nonverbal communication cues active Listening The first communication skill to be mastered is listening, specifically active listen- ing. Listening is defined as hearing what is being said, whereas active listening is a dynamic process that includes both hearing what is being said as well as processing and interpreting the words that are spoken (and/or unspoken) to understand the complete message that is being delivered. Whereas listening is a passive process, active listening requires the listener to consciously choose to give the patient atten- tion and concentration that is free of distractions and interruptions, both external and internal. External distractions include ringing telephones, flickering computer screens, and other infringing per- sonal and/or other duties. These external distractions can be avoided by interacting with your patient in a place that is free of such distractions. Internal distractions occur for two major reasons: (1) many matters, unre- lated to the patient in front of you, may occupy your mind and (2) it is difficult 4 chapter 1 / the patient interview to perceive what the patient is saying without tainting his or her message with your personal judgment. The first reason can be addressed by making a conscious effort to concentrate solely on your interaction with the patient. This is more dif- ficult to accomplish than it sounds, but, with practice, turning on the “listening switch” in your mind will become easier. The second reason is more difficult to 1 address, because instinct often leads us to judge or evaluate what the patient is saying based on our own frame of reference. Biases, prejudices, and judgments cloud the message that is being delivered by the patient, which, in turn, affect the patient interaction, and possibly clinical outcomes. For example, as you prepare 2 for a patient who has been referred to you for smoking cessation counseling, you read in several progress notes that the patient “refuses to give up smoking. Therefore, as your patient is talking about reasons why it is difficult for him to quit smoking, your mind is hearing what is being said but is interpreting it as excuses rather than reasons that you may be able to address with the patient to assist him in quitting smoking. One way to overcome internal distractions is by being present in the moment, during your patient visit, addressing your patient’s current concerns without focusing on your preconceived notions. Sympathy is when you feel sorry for the patient but do not feel the same emotions or are not in the same situation, whereas empathy is when you place yourself in your patient’s situation and respond based on either similar personal experiences or through vicarious understanding. When you express empathy, it allows your patient to feel as though you understand his or her unique experience and that you are applying your expertise to the patient as an individual. Empathy can be shown in several ways, and each way will depend upon the partic- ular patient as well as the situation. For example, nodding your head, making a state- ment, or asking a follow-up question can show empathy. For example, saying to your patient who has been communication skills 5 diagnosed with cancer, “I know just how you are feeling. At first, he was just so overwhelmed and upset” may make the patient feel like you are not truly listening to her, but rather assuming that she will respond like anyone else with a cancer diagnosis. It may be better to say, “I know from some personal experiences that finding out about cancer can be very overwhelming. Building a good rapport sets the tone for the interview and allows the patient to feel comfortable with you, thereby making the lines of communication more open and honest. Patients may sometimes withhold information if they feel uncomfortable or anxious about sharing their complaints because of a lack of feeling respected, feeling as though their words are not being heard, or quite simply not knowing who you are and what your role is in their care. Therefore, starting the interview by greeting the patient by name, making sure you are pronouncing the patient’s name correctly, asking how he or she prefers to be addressed, and adding a title to his or her name, if preferred, will indicate your interest in the patient and show that you care. You should also give your name and title and then briefly describe the purpose of the interview. I am the pharmacist who is part of your medical team, and I am here to ask you a few questions about what brought you to the hospital and discuss the medications you have been taking at home. Is it okay for me to speak to you with your family/friends in the room or would you prefer to be alone while we talk? In general, open-ended questioning is the preferred technique to use during patient interviews to compel the patient to provide more in-depth and insightful responses. Because open- ended questions do not limit the patient to responding with a yes or no, they encour- age the patient to disclose more information. For example, you can start the interview by asking an open-ended question, such as “How are you feeling today? For example, if you ask the patient a closed-ended question such as, “Do you take your medications as directed by your physician? Instead, if you ask the patient an open- ended question, such as “How are you taking this medication? By gathering more information with open-ended questioning, you may learn that there are dis- crepancies between how the patient is actually taking the medication and how it has been prescribed. Oftentimes, a patient answers, “Yes, I am taking it as directed,” but you then discover that this is not the case, perhaps as a result of dishonesty but more likely because the patient believes that he or she is taking the medication correctly. The use of open-ended questions enables you to gather more information from the patient and to be more complete and accurate in your assessment; this, in turn, leads to appropriate patient-specific care. Closed-ended questions do play a role in communicating with a patient; however, the use of close-ended questions should be specific to the information you want to col- lect. For example, if you would like to know whether the patient took his or her blood pressure medication in the morning to more accurately assess his or her blood pressure reading, you might ask, “Did you take your blood pressure medications this morning? For example, after asking an open-ended question such as “What symptoms communication skills 7 are you currently experiencing? These questions lead a patient to provide a response that he or she perceives to be the answer that the inter- viewer wants to hear. An example of a leading question is “You do not miss any doses of your medication, do you? Therefore, to obtain an accurate response to your questions, leading questions should be avoided. By allowing moments of silence after asking a question, the patient is able to reflect upon your question and provide a more thoughtful and accurate response. However, silence may also indicate that the patient has not understood your question. You can use nonver- bal cues to gauge each patient independently to determine the appropriate length of time to be silent and/or when to break the silence. In general, the silence should be long enough to provide the patient a chance to gather his or her thoughts but not so long as to make the patient feel uncomfortable. Although it may be necessary to learn the reasoning behind the patient’s choices and actions, the wording that you use may impact the response. For example, if you desire to learn why a patient is missing doses of hydrochlorothiazide, instead of asking “Why do you miss your doses? With the “why” method, the patient may feel the need to defend him- or herself, whereas 8 chapter 1 / the patient interview the “what” method allows the patient to reflect on his or her reasons without feeling as though you are offering judgment. This type of communication plays an important role in your interactions with your patients because it can be as powerful as the words that are spoken. Nonverbal communication includes tone of voice, choice of language, facial expressions, body posture and position, gestures, eye contact, appearance, and overall behavior. A patient’s perception of nonverbal communication may be influenced by 1 individual and cultural differences. Therefore, you should be sensitive to cultural dif- ferences prior to making inferences about the patient based on nonverbal communica- tion. Many factors may affect a patient’s reliability, including cer- tain psychiatric conditions, impaired cognitive function, inadequate memory recall, or even a lack of understanding of the questions being asked. Therefore, it is important to assess the patient’s reliability during the interview. Listening for and recognizing clues that the patient may not be relaying accurate information, no matter the reason, takes experience.
