These biological effects are usually produced by an interaction of the drug with specific receptors at the drug’s site of action. In some cases, delivery and targeting barriers may be so great as to preclude the use of an otherwise effective drug candidate. The purpose of any delivery system is to enhance or facilitate the action of therapeutic compounds. Ideally, a drug delivery system could deliver the correct amount of drug to the site of action at the correct rate and timing, in order to maximize the desired therapeutic response. Specialized drug delivery systems constitute a relatively recent addition to the field of pharmaceutical technology. Up until the 1940s conventional dosage forms essentially comprised: • injections; • oral formulations (solutions, suspensions, tablets and capsules); • topical creams and ointments. Parenteral delivery is highly invasive, generally requires intervention by clinicians and the effects are usually short-lived. Although oral administration is highly convenient, many drugs, such as insulin, cannot be given by this route due to poor absorption characteristics and/or propensity to degrade in the gastrointestinal tract. Topical creams and ointments were limited to topical rather than systemic effects. Dosage forms became more advanced during the 1950s and 1960s; however, drug delivery technology was mainly limited to sustained-release delivery via the oral route. An example of an oral sustained-release formulation from this period is the Spansule capsule technology developed by Smith Kline and French Laboratories. As the pellets travel down the gastrointestinal tract, the coating material dissolves to release the drug. By using a capsule containing pellets incorporating a spectrum of different thickness coatings (and thus dissolution rates), sustained drug release of a given pattern is possible. It was not until the 1970s, with the advent of dedicated drug delivery research companies, that significant advances in drug delivery technology were made. The recognition that specific research had to be undertaken in order to overcome the problems of conventional drug delivery led to the evolution of modern- day pharmaceutical science and technology. The phenomenal advances in the fields of biotechnology and molecular biology gave an additional impetus to drug delivery research in the 1980s and early 1990s. These advances provided large quantities of new biopharmaceuticals, such as peptides, proteins and antisense oligonucleotides, which generally possess inherent disadvantages for drug delivery. Disadvantages include such properties as large molecular size, hydrophilicity and instability, making these “new biotherapeutics” unsuitable for oral delivery. Generally such drugs must be given by the parenteral route, which has many associated disadvantages, as mentioned above. Recent research has been directed towards the use of alternatives to the parenteral route, for drugs (including the “new biotherapeutics”) that cannot be delivered orally. Potential alternative portals of drug entry to the systemic circulation include the buccal, sublingual, nasal, pulmonary and vaginal routes. These routes are also being studied for the local delivery of drugs directly to the site of action, thereby reducing the dose needed to produce a pharmacological effect and also possibly minimizing systemic side-effects. Drug delivery technology is becoming increasingly sophisticated and current approaches take into account such factors as the influence of pharmacokinetic processes on drug efficacy, as well as the importance of drug timing and of drug targeting to the site of action. Emerging technologies are addressing a variety of issues, including bio-responsive drug release and the delivery of nucleic acid therapeutic entities. This book is concerned with the various routes of delivery under investigation, and these new and 3 emerging delivery technologies. However, a full appreciation of these concerns cannot be gained without first understanding: • the concept of bioavailability; • the process of drug absorption; • the pharmacokinetic processes; • the importance of timing for optimal drug therapy; • delivery considerations for the “new biotherapeutics”; • the limitations of conventional therapy. This chapter provides an overview of these considerations and highlights the necessity for advanced drug delivery systems, in order to optimize drug efficacy.

Ethambutol The ethylenediamine derivative ethambutol (9-6)isanother agent used as a component in fixed tuberculostatic drug com- binations containing order motrin 400mg otc, for example quality motrin 600mg, rifampicin, isoniazide, and pyrazinamide. Ethambutol is a specific tuberculostatic drug which has been used for this purpose since the beginning of the 1960s. Despite many years of clinical use of ethambu- tol, its mechanism of action has not been known until relatively recently. The ethambutol-mediated interference with mycobacterial cell wall formation is regarded as being able to increase the per- meability for other antimycobacterial agents and thus contribute to that valuable clinical synergism, observed for example at the combination of ethambutol with rifampicin, which is a large molecule whose size interferes with permeability. Resistance to ethambutol has been observed, and was in many cases, but not all, shown to be caused by spontaneously occurring mutational changes in the synthesis regulation of the enzymes involved in the polymerization of arabinose. Cycloserine Cycloserine was used as a remedy against tuberculosis, but is not used much clinically nowadays because of the central ner- vous system disturbances that were sometimes experienced by patients. It is a true antibiotic in the sense that it was originally isolated from several Streptomyces species, among them S. D-Cycloserine (9-7)has a simple chemical configuration and is a structural analog of D-alanine. D-Cycloserine is a broad-spectrum antibiotic with a particularly good effect on mycobacteria, among them M. One is L-alanine racemase, forming D-alanine from L-alanine; the other is D-alanine-D-alanine synthetase. It should be mentioned that D-cycloserine has a 100-fold higher affinity for D-alanine-D-alanine synthetase than does the normal D-alanine substrate. The final effect of D-cycloserine is similar to that of betalactams, of glycopeptides, and also of phosphomycin, in that the bacterium affected is unable to form the crucial transpeptidase cross-links for murein stability and thus for a stable cell wall. It is caused by spontaneous mutations in the genes expressing L-alanine racemase and D-alanine-D-alanine synthetase to lower the affinity of D-cycloserine for these enzymes. Also, changes in the alanine permease transporting D-cycloserine into the cell have been shown to mediate resistance to the drug. Finally, we note that the side effect of D-cycloserine causing disturbances in the cen- tral nervous system has recently been turned into an advantage in that when it is administered as a drug, it functions as an adjuvant to cognitive behavioral therapy in the treatment of obsessive-compulsive disorder. It works as an analog of p-aminobenzoic acid and inhibits folic acid synthesis in M. It has been used as a standard remedy since 1946, often in combination with streptomycin mitigating the selection of resistance against the latter. Because of the side effects mentioned, and because of its limited efficiency, it has generally been outcompeted by the more recent antibacterials described earlier in the chapter. Tuberculostatic Drugs Recruited from Earlier Known Groups of Antibiotics Found Originally with Other Antibacterial Spectra As mentioned earlier, penicillins were very early found to have no activity against M. It was recently shown that this is due to the rapid hydrolysis of betalactams by the betalactamase produced from the chromosomal blaCgenein the tuberculosis bacterium (see also Chapter 4). One member of this group has a spectrum of potent and selective antimycobacterial activity in vitro. The mechanism of action seems to be the inhibition of the proton pump of adenosine triphosphate synthase. The Battle Against Tuberculosis The remedies mentioned, together with social measures, have been very successful in limiting tuberculosis in the Western world. Although the original need for 24 months of drug therapy could be reduced to six months, irregular or incom- plete compliance with the regime became an increasing problem. As an example, in some social contexts in New York City, where a combination of poverty and narcotics abuse has led to deteriorating tuberculosis control, a 33% frequency of cases of resistance to at least one drug was observed, and 19% of the cases were resistant to two or more agents. In some developing countries, where resources are limited, drug resistance rates of more than 30% have been observed. This development has occurred because patients either discontinue taking one or more of their multiple drugs or take less than the prescribed dose. It could also be that today’s physicians, who are less familiar with tuberculosis, prescribe inappropri- ately. Insufficient amounts of antibacterials are administered, creating an environment that selects for the survival of drug- resistant mutants. This drug resistance development has led to situations where no remedy is active for treatment, termed extensively drug-resistant tuberculosis.

If you must cough or sneeze and a tissue is not within reach fast enough purchase motrin 400mg overnight delivery, use your clothing! Never order 400mg motrin with amex, never your hands unless you are free to immediately dash into the washroom and clean the contamination off your hands. Teach children this old rearranged verse: If you cough or sneeze or sniff Grab a tissue, quick-quick-quick! Better Housekeeping Throw out as much of the wall to wall carpeting as you can bear to part with. Modern shoes, with their deep treads, bring in huge amounts of outdoor filth which settles deep down into the carpets. When you see how much filth is in the water and realize how much dirt you were living with, you might be willing to trade in the “beauty” of carpets for the cleaner living of smooth floors. Cobalt, which adds “lustre” to carpets, causes skin and heart disease after it has built up in your organs. Nothing controls fleas reliably, except getting rid of the carpets and cloth furniture (keep pets out of bedrooms). Fleas and other vermin in the carpet simply crawl below the wetness level when you wash the carpet. Spraying a grain alco- hol solution with lemon peel in it (it needs to extract for a half hour) on the damp carpet will reach and kill a lot of these, to- gether with the residual bacteria. Molds and bacteria that grow right on the air conditioning unit get blown about for all to inhale. Never, never use fiberglass as a filter or to insulate your air conditioner around the sides. All dirt brought into the house by shoes gets circulated throughout the house by forced air systems of heating or cooling. A return to linoleum floor covering for kitchen and bathroom and hardwood for other rooms would be a good step of progress for a health conscious society. Throw rugs at doors and bedside, easy to clean, would “catch the dirt” as was the original intention. Modern cloth furniture with its foam interior is a repository of filth and fumes and a constant source of infectious dust. You are picking up and removing highly infectious filth (Ascaris and pinworm eggs, pet parasites, “dander” and house mites). Use plain water or vinegar water (50%), not a chemical combination which further pollutes the air. In places like Chicago where you can smell the air as you approach the city, it is wiser to keep your windows shut. Central air conditioning and a plain carbon filter at the furnace location (see Sources) may be the best solution in spite of blowing dust around the house. Keep the vents to the bedrooms closed to re- duce the air turbulence there but leave the cold air return open. Clean the vents in other rooms each week along with floors and carpets by pulling up the grating and reaching down the passage as far as possible. If you believe the air is free of highway exhaust and indus- trial smoke open the windows every day. Asbestos, fiberglass, freon, radon and plain dust can be reduced to a minimum by keeping windows open. Buy such small quantities that you can afford to throw it all away when you are done with them. Move to the other end of the house and furthest away from an attached garage door. Getting Rid of Mites We do not tolerate external parasites like bedbugs, lice, ticks, leeches. Lice were originally “controlled” by frequent washing, louse combs, and ironing the seams of clothing. Never allow a pet into the bedroom or the dust will have tapeworm eggs as well as mites. Deep, soft, wall to wall carpets compromise an ancient concept: everything should be washable and cleanable, without throwing the dirt into the air for humans to inhale.

Our diligent scientists have studied the mechanism of arsenic poisoning in great detail discount 400mg motrin overnight delivery. Then why are we allowed to put it on our lawns to be carried into our carpets via shoes? As a result discount motrin 400mg without prescription, foam fur- niture, pillows and mattresses give off formaldehyde for about two years after manufacturing. If you sleep with your nose buried in a new foam pillow all night, you are risking major lung problems. And what if you found that although many people had them, those who were sick with a cold always had at least one of them. Would you ask whether a sudden buildup of mycotoxins is what really lets colds develop? What if you always found every mysteriously ill person had some unsuspected parasite or pollutant? They forced me to alter my entire outlook on what really causes some of our “incurable”, mysterious diseases. This multicausal concept is what made the study of medicine so difficult that only a few could undertake it. But these diagnoses are based on a description of what is happening at a particular place in your body. This is like calling a mosquito bite behind the ears by one name and a mosquito bite behind the knee by another name. If you never see the true cause, a mosquito at work, this system could be excused as somewhat sensible. And you can find them yourself by building the electronic diagnostic circuit (page 457)! Once you have seen a mosquito at work on your body you no longer need to go to the doctor for a red, itchy bump. Once you have seen how common house dust is implicated in the common cold you get rid of the house dust. Once you have seen the mold in your food facilitate the cold virus you throw out that moldy food. The electronic resonance method described in this book will let you see all these things for yourself. You are not a hapless pawn attacked by bacteria and viruses that dart at you from nowhere to make you ill. You are not at the mercy of diseases all around you, hoping, by chance, to escape, like a soldier hoping to come home from the war. You can replace faith with your own hard headed observations by building the diagnostic circuit (Syncrometer). When you personally find the mold in your peanut butter, or Shigella in your cheese, you have the knowledge, not faith, that convinces and guides you. That it is due to “catching something”, not eating what we should, like roughage or vitamins, or not doing what we should, like dressing properly, exercising or going to bed on time. The current concepts on disease causation blaming our actions and our genes are simply not logical. After you have found the parasite interlopers hiding in your body you can kill them electronically. And after you have iden- tified the pollutants stuck in your organs you can stop eating them, breathing them or putting them on yourself. In response, your body will begin to heal, just as surely as a mosquito bite heals. It will be an exciting adventure to watch yourself lose your symptoms and get stronger. Self Health The entire purpose of this book is to enable you to diag- nose and treat yourself for any disease. You have three new approaches that make this wish a reality: the understanding that only pollution and parasites make you sick, the quick and inex- pensive diagnostic circuit that lets you find which pollutants and parasites they are, and the zapper or herbal recipe that kills the parasites.
