Table 7-3 Cost/Benefit Analysis of Prudence’s Perfectionism Schema: Part 2 Benefits Costs My income is higher because of my I don’t have much time for fun buy rizatriptan 10mg low cost pain treatment for endometriosis. Chapter 7: Busting Up Your Agitating Assumptions 111 Benefits Costs Actually cheap rizatriptan 10 mg mastercard chronic pain syndrome treatment guidelines, I think my focus on work has kept me from finding a mean- ingful relationship. The cost/benefit analysis helps you to know whether you really want to chal- lenge your agitating assumptions. The final step is to examine carefully whether you would lose all the benefits by chang- ing the assumption. For example, Prudence attributes her high income to her dedication and long work hours. Perhaps she’s partly right, but would her income evaporate if she worked just a little less? Most likely, if she worked less, her income might drop a bit, but with less anxiety, she might increase her efficiency enough to make up the difference. If she were less irritable, she would be able to retain her secretarial staff and gain efficiency there too. And would Prudence actually start making more mistakes if she relaxed her standards? With respect to her niece, Prudence isn’t really getting the benefit that she thinks she is, because she’s not around enough to serve as an effective role model. So you see, many times the perceived benefits of an assumption evaporate upon close inspection. A little bit of anxiety seems to improve perfor- anxiety interferes with the ability to recall previ- mance and reduce mistakes. Some anxiety ously learned information, and mistakes multi- channels attention and effort to the task at hand. That’s why people with perfection schemas Without anxiety, people don’t take tasks seri- often have severe test anxiety. However, when material, but their anxiety causes them to forget perfectionism reaches extreme levels, so does what they have previously learned. That’s because they fear that letting go of their worry habit will result in abandonment or rejection. Anne, a graduate student in social work, has to meet each week with her advisor for supervision of her casework. Anne does plenty for her clients; she does anything that she thinks they may need help with — spending hours of her own time, even running errands for them if they ask. Her supervisor tries to tell her to pull back from giving excessive help to her clients; he says that her bending over backwards to assist clients doesn’t help her or her clients. However, Anne’s worst fears surround the required presentations in front of graduate school classmates. Before giving talks to her classmates, she spends an abundance of time in the bathroom feeling ill. During lively dis- cussions in her class, Anne remains quiet and almost never takes sides. Well, a cost/benefit analysis of Anne’s approval schema reveals that people walk all over her. It also shows that fellow students fail to appreciate how bright she is, because she rarely speaks up in class. Anne neglects her own needs and at times feels resentful when she does so much for others and they do so little to return the favor. Sure, she rarely receives criticism, but because she takes so few risks, she never gets the approval and praise that she really wants. Reviewing vulnerability The anxious schema of vulnerability plagues people with worries about their safety, livelihood, and security. People with this schema often receive a diagnosis of Generalized Anxiety Disorder (see Chapter 2). Peter, a college graduate with a business degree, receives a promotion that requires him to move to California, but he turns it down because Chapter 7: Busting Up Your Agitating Assumptions 113 he fears big cities and earthquakes. Peter watches the weather chan- nel and listens to the news before he ventures any distance from home and avoids driving if the radio reports any chance of inclement weather. He also worries about his health and often visits his doctor, complaining of vague symptoms, such as nausea, head- aches, and fatigue.

It is in one of three directions - excess order rizatriptan 10mg free shipping pain research and treatment journal impact factor, defect discount 10mg rizatriptan visa pain medication for dogs with bone cancer, or perversion - above, below, or from. If we can measure disease in this way, the desired remedial action is at once suggested - if in excess it is to be diminished, if defective it is to be increased, if perverted it is to be brought back to the normal standard. In a majority of acute diseases, we will find these departures so clearly marked that the diagnosis and treatment are very easy. These will be found in varying combination, yet in most cases there are certain prominent lesions which may be regarded as standing first in the chain of morbid phenomena and upon which the others rest. If we can find remedies which will reach and correct these, the disease is at an end, and the natural restorative power of the body soon gives health. The most simple form of specific medication is where a single remedy is sufficient to arrest the process of disease. As when we prescribe Collinsonia for ministers’ sore throat, Drosera for the cough of measles, Belladonna for congestive headache, Macrotys for muscular pains, Hamamelis for hemorrhoids, Phytolacca for mammary irritation, Cactus for functional heart disease, Staphysagria for prostatorrhœa, etc. This use of remedies gives great satisfaction in the treatment of many diseases, and we are led to wish that the practice of medicine could be resolved into the giving of such specifics. Not quite so simple, but yet very plain is the second form of direct medication, illustrated by the following examples. A heavily loaded tongue at base, with a bad taste in the mouth and fullness in the epigastric region, demanding an emetic. A uniformly yellowish coated tongue from base to tip, relieved by Podophyllin or Leptandrin. A pallid large tongue, with a moist pasty coat, demanding the alkaline sulphites, say sulphite of soda. Quite as plain, but not so easily and directly reached by medicine, is the need of a good condition of the intestinal canal for digestion and blood making, and associated with it the recognition of the need of certain restoratives that may be necessary to normal nutrition and functional activity. In acute cases, it is required first to rid our patient of functional disease before we can fully establish digestion and nutrition, but in chronic disease it will many times stand first, and must always be associated with treatment for local lesions. The complement of this is, treatment to increase the removal of old and worn-out tissues, and thus relieve the solids and fluids of material that must necessarily depress functional activity. Probably we have as little positive knowledge of remedies that increase retrograde metamorphosis, as of any other class, still they are being studied, and in time we will be enabled to use them directly. Remedies that increase excretion are in common use, and form a very important part of our practice. From the earliest periods of medicine, the fact that disease is destructive has been recognized. Destruction of the material of our bodies, necessarily leaves the debris either in solids or fluids, and experience has shown that it can not remain in the body with safety. But there has been a failure to appreciate the true nature of these processes, and from this has flowed a very great deal of bad practice. These processes are strictly vital processes, carried on by delicate organisms under the control of the nervous system. As they are the basis of life, we may well suppose that nature has guarded them on all sides, and that they are the true centre of life. The doctor of the olden time has looked upon them as mechanisms to be powerfully influenced by remedies. He powerfully excites the stomach and intestinal canal as a means of derivation, and works upon the skin and kidneys as if secretion from them were a purely physical process. Any one who will take up Huxley’s Physiology, and read the clear and simple description of this apparatus for digestion and waste, upon which our lives rest, can not but be satisfied that the common practice of medicine is a very great wrong. Take away this power and he will die in a brief time; take it away in part, and you have lessened his power to that extent; take it away for an hour, for a day, or for a week, and his power to live is weakened to that extent. Studying the condition of the stomach and intestinal canal in this light, we will see how a direct stimulant, or tonic, an alkali, an acid, a remedy that will relieve nervous irritation, or one that will give increased innervation, will in different cases be an aid to digestion. Looking farther, we will see the necessity, in one case of histogenetic food, in another of calorifacient, in one of iron, in another of phosphorus, etc. It is just as much specific medication to be able to select the proper food for the sick as it is the proper medicine.

Add 6 drops of Lugol’s (not more generic 10mg rizatriptan fast delivery pain medication for dogs with arthritis, not less) rizatriptan 10 mg online pain medication for dogs surgery, stir with wood or plastic, and drink all at once. Take this dose 4 times a day, after meals and at bedtime, for 3 days in a row, then as needed. Notice how calming 6 drops of Lugol’s can be, soothing a manic stage and bringing a peaceful state where anxiety ruled before. Lugol’s is perfectly safe (if not allergic) to take day after day, when needed, because of its peculiar attaching property. Doomed are all Salmonellas; doomed also are eggs of parasites that might be in the stomach (cysts). In the past, 2/3 of a teaspoon (60 drops) of Lugol’s was the standard dose of iodine given to persons with thyroid disease. The concept of supplementing the diet is excellent, but the pollution problem makes it prohibitive. Use only supplements and brands recommended in Sources, although the best approach is to test them yourself with your Syncrometer. Home Clean-up This is the easiest task because it mostly involves throwing things out. Your Basement To clean your basement, remove all paint, varnish, thinners, brush cleaners, and related supplies. You may keep your laundry supplies: borax, washing soda, white distilled vinegar, bleach and homemade soap. Also move any car tires and automotive supplies like waxes, oil, transmission fluid, and the spare gas can (even if it is empty) into your garage or discard them. Tack a sheet of plastic over it to slow down the rate of fume entrance into the house. Your house is taller and warmer than the garage so garage-air is pulled in and up as the warm air in the house rises. But what of the gasoline and motor fumes we are getting now due to parked vehicles? If your garage is under your house, you cannot keep the pollution from entering your home. Remove window air condi- tioners or test the dust in your home (page 485) for Freon. Would Freon react with ozone supplied to your body and thereby become biodegradable? Other ozone routes, as intravenous or rectal, have not been observed to be as effective. If you are following your progress with the Syncrometer, you will see that Freon now appears in the liver for the first time. A combination of herbs (Liver Herb Drink in Recipes, page 552) rescues the liver from its plight, and prevents the indiges- tion. After drinking liver herbs you will see that the Freon now appears in the kidneys. Take the kidney cleanse to assist the kidneys so they can finally excrete the Freon into the urine. Although toxic, at least I observe it in the liver directly, suggesting that your body is capable of handling it. Special Clean-up for Fiberglass Fiberglass insulation has microscopically small bits of glass that are free to blow into the air. They cut their way through your lungs and organs like millions of tiny knives, spreading through your body, since there is no way out for them. Your body, though, recognizes these sharp, pointed bits and tries to stop their spread by sequestering them in cysts. Most solid malignant tumors contain fiberglass or asbestos, another glass-like particle. In nearly all cases a hole can be found in the ceiling or walls, leading to fiberglass insulated parts of the house. When these holes are sealed in an air-tight manner the house air no longer is positive for fiberglass. Search for small screw holes intended for pictures, or electric outlet plates that are missing. Also remove fiberglass jackets from water heater and fiber- glass filter from furnace.

Infection by cytopathic pathogens can only be controlled if pathogenic proliferation is slow and the pathogen remains localized; otherwise the outcome is usually fatal. In the case of noncytopathic pathogens, the cytotoxic T-cell response is the critical parameter. The T-cell response can be halted by pathogens which proliferate rapidly and spread widely due to the deletion of responding Tcells. For pathogens which exhibit moderate rates of proliferation and spread, the T-cell response may cause extensive immunopathological damage, and thus reduce the proportion of surviving hosts, some of which will controll virus, some not. A weakened immune defense system may not progress beyond an unfavorable virus-host balance, even when confronted with a static or slowly replicating patho- gen which represents an initially favorable balance. Although de- tails of the process are still sketchy, IgE-dependent basophil and eosinophil defense mechanisms have been described for model schistosomal infections. Usage subject to terms and conditions of license 102 2 Basic Principles of Immunology & Avoidance strategies. Infectious agents have developed a variety of stra- tegies by which they can sometimes succeed in circumventing or escaping immune responses, often by inhibiting cytokine action. Short-lived IgM responses can control bacteria in the blood effectively, but are usually insufficient in the controlof toxins. In such cases, immunoglobulinsof the IgGclass are more efficient, as a result of their longer half-life and greater facility for diffusing into tissues. Avoidance Mechanisms of Pathogens (with examples) Influence on the complement system. Some pathogens prevent complement fac- tors from binding to their surfaces: & Prevention of C4b binding; herpes virus, smallpox virus. Viruses can avoid confrontation with the immune defenses by restricting their location to peripheral cells and or- gans located outside of lymphoid tissues: & Papilloma viruses; infect keratinocytes. Infection agents can avoid immune defenses by mutating or reducing their expression of T- or B-cell epitopes. Usage subject to terms and conditions of license Immune Defenses against Infection and Tumor Immunity 103 Continued: Avoidance Mechanisms of Pathogens (with examples) Influence on lymphocytes and immunosuppression. Immune Protection and Immunopathology Whether the consequences of an immune response are protective or harmful depends on the balance between infectious spread and the strength of the ensuing immune response. As for most biological systems, the immune de- fense system is optimized to succeed in 50–90% of cases, not for 100% of cases. For example, immune destruction of virus-infested host cells during the eclipse phase of a virus infection represents a potent means of preventing virus replication (Fig. If a noncytopathic virus is not brought under im- mediate control, the primary illness is not severe—however, the delayed cy- totoxic response may then lead to the destruction of very large numbers of infected host cells and thus exacerbate disease (Tables 2.

A similar situation is also observed for the cellular immune response against facultative intracellular tuberculosis and leprosy bacilli which themselves have relatively low levels of pathogenicity (Table 2. A healthy immune system will normally bring such infectious agents under control efficiently, and the immunological cell and tissue damage (which oc- curs in parallel with the elimination of the pathogen) will be minimal, en- suring that there is little by wayof pathological or clinical consequence. How- ever, should the immune system allow these agents to spread further, the result will be a chronic immunopathological response and resultant tissue destruction—as seen during hepatitis B as chronic or acute aggressive hepatitis and in leprosy as the tuberculoid form. Should a rapidly spreading infection result in exhaustion of the T cell response, or should an insufficient level of immunity be generated, the infected host will become a carrier. This carrier state, which only occurs during infections characterized by an absent or low- level of cytopathology, is convincingly demonstrated in hepatitis B carriers and sufferers of lepromatous leprosy.

A company is trying to develop a reservoir-type polymeric implant for the controlled release of estradiol for 3 months buy rizatriptan 10mg visa pain medication for dogs with bite wounds. Which techniques would you recommend to the company to increase the drug release rate? A new steroidal drug is allowed to pass through a siloxane membrane (surface area=23 buy 10mg rizatriptan mastercard midwest pain treatment center ohio. Provided that the drug release rate is constant, calculate the flux (F) that is defined as the amount of a solute flowing through a membrane per unit time. The release rate of a drug from conventional non-degradable matrix-type polymeric implant usually decreases over time. What is the main reason for developing a reservoir/matrix hybrid-type polymeric implant? Which polymer is most extensively used as non-degradable nonporous membrane to develop reservoir-type polymeric implants? Which of the following is/are an example(s) of non-biodegradable matrix-type implant? What is the principle that has been utilized in the development of the Alzet and the Duros implant pumps in which a drug solution or suspension is confined in a semi-permeable membrane that allows only water molecules to move through it? The release rate (dM/dt) of a drug from an osmotic pump can be described as C (dV/dt)d where Cd is the drug solubility in its reservoir compartment. The effective surface area, permeability coefficient, thickness, and osmotic reflection coefficient of the semi-permeable membrane used for the pump are 3. If we change the reservoir medium and osmotic agent to increase C ofd the drug from 100 to 300 mg/ml and to increase ∆π from 100 to 300 atm, by how much will the release rate of the drug increase? The most important routes of injection of these sterile products are intramuscular (im), intravenous (iv) and subcutaneous (sc). The detailed description of 106 these areas of pharmaceutics lie outside the remit of this text and the reader is refered to information provided in the further reading section of Chapter 1. This chapter focuses on advanced drug delivery and targeting systems administered via the parenteral route and serves to provide the reader with a basic understanding of the principal approaches to drug targeting. An intravenously administered drug is subject to a number of pharmacokinetic processes in vivo which can decrease the drugs therapeutic index, including: • Distribution: intravenously administered drugs distribute throughout the body and reach non-target organs and tissues, resulting in drug wastage and (possibly) toxic side-effects. As a result of these processes, only a small fraction of the drug will reach the target tissue. Moreover, it may be cleared rapidly from this site and, therefore, not be available long enough to induce the desired effect. Reaching the target cell is often not the ultimate goal; in many cases the drug has to enter the target cell to reach an intracellular target site. Again, as discussed in Chapter 1, many drugs do not possess the required physicochemical properties to enter target cells; they may be too hydrophilic, too large or not transportable by the available active-transport systems. For example, the drug may work outside the cell, thus cell penetration may not be necessary. In this chapter there are also examples mentioned of passive targeting approaches (see below), where the drug does not have to be specifically targeted to the cell or tissue. The parenteral route of administration is associated with several major disadvantages (see Section 3. Parenteral administration is invasive and may require the intervention of trained medical professionals. Strict regulations for parenteral formulations govern their use and generally dictate that they are as simple as possible and the inclusion of excipients in the formulation is kept to an absolute minimum. Such drugs include those used in treatment of cancer, as well as life-threatening microbial, viral and fungal diseases. If prolonged release of a drug via the parenteral route is required, subcutaneous or intramuscular injection of a controlled-release system is the first option to consider. For example, galactose receptors are present on liver parenchymal cells, thus the inclusion of galactose residues on a drug carrier can target the carrier to these cells. A number of different target-specific recognition moieties are available and discussed further below. However, an important point to note here is that target-specific recognition moieties are not the idealized “magic bullets”, capable of selectively directing the drug to the appropriate target and ignoring all other non-target sites.

The “new biotherapeutics” include such moieties as novel peptide and protein drugs and vaccines, genes and oligonucleotide therapies. However, their potential is severely compromised by the significant delivery and targeting obstacles which prevail in vivo. These obstacles are often so great that effective drug delivery and targeting is now recognized as the key to the effective development of many therapeutics. In response, the field of advanced drug delivery and targeting has seen an explosion of activity, as researchers address these obstacles and try to facilitate or enhance the action of the new biotherapeutics, as well as conventional drugs. Activity in the field includes the development of novel drug delivery systems to circumvent the various pharmacokinetic obstacles that can result in zero or minimal drug absorption, unwanted distribution, and premature inactivation and elimination. Technologies are also addressing ways to minimize drug toxicity or immunogenicity, or to enhance vaccine immunogenicity. The importance of drug targeting to the site of action is the subject of intense research interest, as are considerations of the importance of drug timing to optimize therapeutic regimens, with the ongoing development of controlled, pulsatile and bio-responsive release systems. Although this is an expanding field of crucial importance to therapeutics, there is currently no single text that covers all aspects of advanced drug delivery and targeting, at an appropriate level for undergraduate and continuing education courses. General pharmacy textbooks, concerned with the rudimentaries, are of necessity limited to conventional pharmaceutical formulations such as tablets, capsules and topical creams. At the other extreme, existing texts relating to this field tend to focus on a single aspect of drug delivery and targeting, or constitute the proceedings of specialized conferences and are, as such, invariably complex and esoteric. This book aims to bridge this gap, by providing a single, comprehensive text which describes the fundamental technological and scientific principles of advanced drug delivery and targeting, their current applications and potential future developments. This book is primarily intended for undergraduate and postgraduate students taking courses in relevant aspects of the biological sciences. In particular, it should prove useful to students undertaking programs in pharmacy, pharmaceutical science, medicine, dentistry, biochemistry, bioengineering, biotechnology, or other related biomedical subjects. It is hoped it will also serve as an introductory text and source of reference for those employed in the (bio) pharmaceutical sector, professions allied to medicine and pharmacists in practice. Section 1 serves as an introduction to the field of advanced drug delivery and targeting. The opening chapter introduces such concepts as bioavailability, the pharmacokinetic processes, the importance of timing for optimal therapy and the special delivery considerations for the new biotherapeutics. In doing so this chapter also highlights the necessity for advanced drug delivery and targeting systems in order to optimize therapeutic efficacy. The therapeutic impetus for advanced delivery systems is further compounded by commercial interests, which are described in Chapter 2. A broad overview of advanced drug delivery and targeting is then provided (Chapter 3), which introduces the terminology and various key concepts pertinent to this subject.
