Provision of patient education in combination with bimonthly cholesterol testing in a community pharmacy resulted in a significant reduction in cholesterol values over a 6-mo study."" Changes in patient-reported behaviors such as dietary habits and exercise were also noted. Although the lack of control group made this study less than definitive, it indicated that a combination of cholesterol monitoring and education could result in lower cholesterol concentrations. A second study demonstrated that screen-...

The maximum changes achieved in a study were -20% total serum cholesterol, -40% serum triglycerides and +15% HDL-cholesterol [2]. However, there are considerable short- and long-term side-effects. The treatment should therefore be monitored by a doctor. 

The patient will usually take these drugs on an outpatient basis and come to the clinic or the primary health care provider s office for periodic monitoring. Frequent monitoring of blood cholesterol and triglyceride levels is done as a part of the ongoing assessment. 

Data about curcunfin encapsulated in liposomes have been reported recently. The authors encapsulated curcumin into a liposomal delivery system in order to study the in vitro and in vivo effects of this compound on proliferation, apoptosis, signaling, and angiogenesis using human pancreatic carcinoma cells. Carotenoids of different polarities and in competition with cholesterol were specifically incorporated into liposomes in order to mimic the physiological uptake by cells and monitor their antioxidant capacities. ... 

Solubilization of an active H,K-ATPase is also a prerequisite for reconstitution of the enzyme into liposomes. With these H,K-ATPase proteoliposomes it is then possible to study the transport characteristics of pure H,K-ATPase, without the interference of residual protein contamination that is usually present in native vesicular H,K-ATPase preparations. Rabon et al. [118] first reported the reconstitution of choleate or n-octylglucoside solubilized H,K-ATPase into phosphatidylcholine-cholesterol liposomes. The enzyme was reconstituted asymmetrically into the proteoliposomes with 70% of the pump molecules having the cytoplasmic side extravesicular. In the presence of intravesicular K, the proteoliposomes exhibited an Mg-ATP-dependent H transport, as monitored by acridine orange fluorescence quenching. Moreover, as seen with native H,K-ATPase vesicles, reconstituted H,K-... 

The development of CHD is a lifelong process. Except in rare cases of severely elevated serum cholesterol levels, years of poor dietary habits, sedentary lifestyle, and life-habit risk factors (e.g., smoking and obesity) contribute to the development of atherosclerosis.3 Unfortunately, many individuals at risk for CHD do not receive lipid-lowering therapy or are not optimally treated. This chapter will help identify individuals at risk, assess treatment goals based on the level of CHD risk, and implement optimal treatment strategies and monitoring plans. 

Fibrates are the most effective triglyceride-lowering agents and also raise HDL cholesterol levels. Combination therapy with a fibrate, particularly gemfibrozil, and a statin has been found to increase the risk for myopathy. Of the 31 rhabdomyolysis deaths reported with cerivastatin use, 12 involved concomitant gemfibrozil.25 Therefore, more frequent monitoring, thorough patient education, and consideration of factors that increase the risk as reviewed previously should be considered. 

Whatever the technique used, it is important to note that (i) only an equivalent viscosity can be determined, (ii) the response of a probe may be different in solvents of the same viscosity but of different chemical nature and structure, (iii) the measured equivalent viscosity often depends on the probe and on the fluorescence technique. Nevertheless, the relative variations of the diffusion coefficient resulting from an external perturbation are generally much less dependent on the technique and on the nature of the probe. Therefore, the fluorescence techniques are very valuable in monitoring changes in fluidity upon an external perturbation such as temperature, pressure and addition of compounds (e.g. cholesterol added to lipid vesicles alcohols and oil added to micellar systems). 

Sometimes it is not possible to measure the direct effect of the drug. Endpoints or surrogate biomarkers are used to monitor the pharmacodynamics and pharmacokinetics of the drug. These markers may be changes in blood pressure, cholesterol level, concentrations of certain enzymes, proteins, blood glucose levels, and similar factors (see Table 6.2 for serum tumor markers and Appendix 7 for general biomarkers). 

Figure 4 Effect on the serum stability of the incorporation of 5% cholesterol poly(ethy-lene glycol) (PEG) into cationic lipoplexes [hpopolyamine RPR209120/DOPE1/1, ratio (mol) lipid/DNA = 10 in 150 mM NaCl]. Lipoplexes were incubated in DMEM + 10% SVF, at 37°C, aliquots were regularly sampled and monitored by dynamic diffusion. Results represent a mean between three measurements. Error bars are not presented to simplify the graph, but differences among PEG, PEG-1, and PEG-2 are significant.

Monitoring Pretreatment and annual exams should include blood pressure, breasts, abdomen and pelvic organs, including Papanicolaou smear. Perform preventative measures and screening, which should include total and HDL cholesterol within 5-year intervals. Advise the pathologist of OC therapy when relevant specimens are submitted. Do not prescribe for more than 1 year without another physical exam. Lipid disorders Closely follow women taking OCs who are being treated for hyperlipidemias.
