Medical requirements

Method, There are two standard methods for the estimation of urea, (i) the hypobromite method, (ii) the urease method (p. 519). The chief merit of the hypobromite method is the rapidity of the analysis the results obtained are considered sufficiently accurate for most medical requirements, e.g., for the estimation of urea in urine. For accurate metabolic work, however, the urease method should be employed.

The goals of maintenance immunosuppression are to further aid in preventing acute rejection episodes and to optimize patient and graft survival Anti-rejection medications require careful selection and dosage titration to balance the risks of rejection with the risks of adverse events. Common maintenance immunosuppressive agents can be divided into four basic medication classes ... 

The calculations involved in critical care include determination of solution strengths, flow rates in terms of drops per minute or hour, and flow rates in volume per unit time. Since the administration of medications requires dose adjustments under a clinical monitoring, it is very important to calculate a titration factor which is the amount of medication in units of weight per drop. Most of these calculations are presented in Chapter 10, but the present section will highlight the calculations which involve the titration factor. The titration factor will help the health care professional to rapidly determine the... 

Cardiovascular disorders Use with extreme caution in patients with cardiovascular disorders because of the possibility of conduction defects, arrhythmias, CHF, sinus tachycardia. Ml, strokes, and tachycardia. These patients require cardiac surveillance at all dose levels of the drug. In high doses, TCAs may produce arrhythmias, sinus tachycardia, conduction defects, and prolonged conduction time. Tachycardia and postural hypotension may occur more frequently with protriptyline. Hyperthyroid patients Hyperthyroid patients or those receiving thyroid medication require close supervision because of the possibility of cardiovascular toxicity, including arrhythmias. 

The rational use of any medication requires a risk versus benefit assessment. Among the myriad of risk factors that complicate this assessment, pregnancy is one of the most perplexing. 

Two recent trials report that treatment of patients earlier in the course of MS— after a first acute clinical demyelinating event—is of value [9,10]. The results of these studies suggest that interferon-P-la may delay the development of a second bout of demyelination. These reports may influence decisions regarding the timing of interferon therapy, but the inconvenience of medication requiring injection, treatment-related side effects, cost, and the lack of evidence of an important long-term benefit of interferon-P will deter many specialists from starting treatment earlier in the course of the disease. 

Advisory mechanisms the creation of a strategic advisory board to advise the VAE and of a Vaccine Acquisition Review Council and a Defense Medical Requirements Coimcil to advise the PEO, and a meeting between responsible DoD officials and the CEOs or COOs of major vaccine manufacturers to explain DoD s needs and to better understand the pharmaceutical industry s view of vaccine development... 

As discussed later in this chapter, optimal dosing of these medications requires TDM at least once early in treatment to adjust for the substantial, primarily genetically determined differences in the elimination rate of these drugs, even in physically healthy individuals. Generally, repeat monitoring is only done for cause, such as the following ... 

When inhaled, it is rapidly active, obviates the need for gastrointestinal absorption (impaired markedly in migraine), and may be titrated to the medical requirement of the patient for symptomatic relief. 

Clinical site personnel—These individuals are responsible for the conduct of the study within the context of the daily clinical environment. Clinical QA must ensure that it is aware of such study medication requirements as appropriate storage and security as well as the importance of maintaining the privacy of study subjects and adequate records. 

Selection of a comprehensive testing battery to record the rate of AChE inhibition is a crucial point. In addition to the estimation of AChE activity, other functions (e.g., sensory systems, reflexes, neuromotor development, locomotion, gait, reactivity to medication) require close monitoring to achieve chemical safety to OPs. In the case of children and workers exposed to very low doses of OPs, other tests should indirectly include parameters like learning, memory loss, social behavior, and reproductive behavior. To integrate behavioral data into the context... 

Step 5 is to establish thresholds for optimal use. Thresholds are the standards against which performance is measured. For example, if the criteria for dosing a medication require that all patients receive a particular dose, without variation, then the threshold will be set at 100% that is, 100% of the patients must receive that dose. It is not necessary to set absolute standards (e.g., 0% therapeutic duplication or 100% compliance with dosage recommendations), because individual variation should be taken into account. A further example of a threshold includes the percentage of patients expected to achieve a certain outcome (e.g., goal blood pressure, 75% adverse reaction, 12%). Clinical pharmacists and physician specialists should... 

Sites are selected as clinics based on the estimates provided by key agencies and businesses. Estimate capacity and vaccine/prophylactic medications required by proposed clinic site vary based on the type of event and the functional capacity of the people coming to that clinic. A nurse can immunize one patient every 1 to 3 minutes depending on those variables. That rule of thumb holds given adequate administrative and secretarial support to handle documentation and overall patient flow in the clinic. The following formula can be used to calculate clinic capacity ... 

As noted in earlier chapters, a positive medication response is rarely immediate. Most psychotropic medications require a number of days or weeks to reach adequate blood levels and produce physiologic changes that yield symptomatic improvement. Also, there exists tremendous variability from patient to patient regarding absorption and metabolism of medications, which affects the ultimate response time. Initial... 

Many pharmaceuticals, including antibiotics and allergy medications, require chlorine-containing compounds for their manufacture. 

Variability in response to medications requires individualization of therapy within existing evidence-based guidelines for management.
