Monitored dosing system

Compliance with awkward regimens such as five times a day may be problematic as usual reference points such as meals are less useful. Mr DM has a combination of regular and when required medication which would make the use of a monitored dosing system (MDS) a challenge. However, symptomatic treatment of nausea, which is usually self-limiting, and constipation are likely to be less of a problem. 

Use patient-friendly packaging, e.g. calendar packs, where appropriate or monitored-dose systems, e.g. boxes compartmented and labelled... 

In the future, monitoring of surface tension could be an attractive option for measuring surfactant concentration. Automatic dosing systems could also be introduced for a controlled supply of concentrated detergents. 

Recently Prokic (1996) developed a system of detection for environmental monitoring. The system consists of three sintered CaS04 Dy pellets and one MgB4(>7 Dy,Na detector. Two Ca sulfate detectors are filtered by 2 and 1.5 mm Cu respectively and the third is only covered by plastic. The low-Z (Z = 8.55) Mg borate detector is covered by only a plastic filter. The Mg borate detector showed one TL peak near 190 C. It was prepared from very pure materials and a special preparation method. Its TL sensitivity exceeded that of TLD-100 by a factor of 6-15. The low-dose limits were 2 and 3 pGy for the Ca sulfate and Mg borate detectors respectively. The detector with the 2 mm Cu filter was used for the determination of the ambient dose equivalent H (10) and that with the 1.5 mm Cu served for the determination of H (0.07) for photons. The ratio of the readings of the unfiltered and the 2 mm Cu filtered detectors provided information of the spectral distribution of the radiation. Wemli (1990) developed a TLD system very similar to the above, to measure the ICRU dose quantities H(10) and H(0.07) in evironmental dosimetry. 

Side Effects and Toxicity. Adverse effects to the tricycHc antidepressants, primarily the result of the actions of these compounds on either the autonomic, cardiovascular, or central nervous systems, are summarized in Table 3. The most serious side effects of the tricycHcs concern the cardiovascular system. Arrhythmias, which are dose-dependent and rarely occur at therapeutic plasma levels, can be life-threatening. In order to prevent adverse effects, as weU as to be certain that the patient has taken enough dmg to be effective, the steady-state semm levels of tricycHc antidepressant dmgs are monitored as a matter of good practice. A comprehensive review of stmcture—activity relationships among the tricycHc antidepressants is available (42). 

Operation When operated correctly, thickeners require a minimum of attention and, if the feed characteristics do not change radically, can be expected to maintain design performance consistently. In this regard, it is usually desirable to monitor feed and underflow rates and sonds concentrations, flocculant dosage rate, and pulp interface level, preferably with dependable instrumentation systems. Process variations are then easily handled by changing the principal operating controls—underflow rate and floccirlant dose—to maintain stability. 

Expert opinion is a source, frequently elicited by survey, that is used to obtain information where no or few data are available. For example, in our experience with a multicountry evaluation of health care resource utilization in atrial fibrillation, very few country-specific published data were available on this subject. Thus the decision-analytic model was supplemented with data from a physician expert panel survey to determine initial management approach (rate control vs. cardioversion) first-, second-, and third-line agents doses and durations of therapy type and frequency of studies that would be performed to initiate and monitor therapy type and frequency of adverse events, by body system and the resources used to manage them place of treatment and adverse consequences of lack of atrial fibrillation control and cost of these consequences, for example, stroke, congestive heart failure. This method may also be used in testing the robustness of the analysis [30]. 

Use of zileuton is uncommon due to the need for dosing four times a day, potential drug interactions, and the potential for hepatotoxicity with the resulting need for frequent monitoring of liver enzymes. In patients started on zileuton, serum alanine aminotransferase concentrations should be monitored before treatment begins, monthly for the first 3 months, every 2 to 3 months for the remainder of the first year, and then periodically thereafter for as long as the patient continues to receive the medication. Zileuton also inhibits the cytochrome P-450 (CYP) mixed function enzyme system and has been shown to decrease the clearance of theophylline, R-warfarin and propranolol.34...
