Perhaps it is really the special bacteria it brings with it that cause the blood vessels to seep or to spasm in the brain order neurontin 600mg with visa, causing pain cheap 400 mg neurontin with visa. Bacteria hidden under a tooth filling or root canal or in a space where once a tooth was pulled can be the cause purchase neurontin 600mg on-line. Staphylo- coccus aureus is a favorite, but various Clostridia, Streps and others are often seen, too. Find an alternative dentist with experience cleaning cavitations and finding small hidden abscesses. If you get immediate relief from dental work, only to lose ground again later, the abscess may have formed again (they are notorious for forming again). Irrigate the dental wound site with white iodine (potassium iodide, 12 drops) or Lugol’s (6 drops) to ¼ cup water using a curved-tip syringe. Use the simple herb, Cascara sagrada, senna tea, or magnesium oxide tablets (2 to 3 a day) to help you eliminate frequently if your own regularity is lacking. Is it the toxins made by bacteria or the inflammation from the bacteria or wormlets themselves that produces the headache? Certainly, one can eat the toxins by themselves in foods like yogurt, cheese, wine, sour cream and develop “royal” headaches. Boil all your dairy foods to prevent Salmonellas and Shigellas from swimming into your beleaguered brain. Begin by killing all Strongyloides and other parasites, bacte- ria and viruses with a zapper. Hopefully, this will only leave a few stragglers behind in abscesses, gallstones and the colon contents. Most people get their Strongyloides back in a few days from pets, other fam- ily members, and themselves! Headaches are also caused by toxins in your environment; especially things you breathe in. Conducting gases through pipes with joints in them, where gases could escape, must be the most ludicrous of all modern “conveniences”. Every gas pipe that has a seam should have a clear plastic boot around it containing indicator compound to let it be known when gas is escaping. As you will see from the case histories, very many persons are living in a cloud of poisonous gas. When your vanadium test is positive, you have a gas leak that your body found, even though the gas company may not. Health Departments and building contractors use modern equipment that detects even the tiniest leak; call them. She was gassy, had pain in her right groin for many years and chronic bladder leakage. Her urinalysis also showed urate crystals and a slight amount of blood, obviously chronic urinary tract infection. The parasite test showed Strongyloides, Trichuris and Fasciolopsis buskii in the intestines. This was tracked down to hurricane lamps that once held coal-oil in them— it filled her house air unbeknownst to her. Thirty five days later she had done an herbal parasite killing program, done the kidney cleanse, cleared out the hurricane lamps and all fuel containers. Three months after that she had done a liver cleanse and gotten abut 3,000 stones out! She tested positive to Histoplasma and Coxsackie virus #4 (a common brain virus) probably stemming from dentalware. After eight months of indecisiveness she was back up to ten headaches per month, although not migraines. She had Strongyloides as well as Ascaris, and other bowel para- sites as did her husband and two children. By one year she was experiencing a couple of good days a month although she still had Ascaris, Coxsackie viruses, and various tooth-related bacteria. Her two and a half year old had swollen neck glands, was toxic with bismuth from disposable diapers but did not have Strongyloides. The eight year old was also toxic with the lotions and fragrance of baby-stuff in the home; she was constantly congested and coughing but became free of Strongyloides in six months. In spite of being on the parasite program two weeks and zapping, he still had Strongyloides. Kenneth Jones had migraines for thirty five years and had tried all the new medications. They worked for a while, then stopped helping, but he continued taking them anyway. He usually went to the emergency room for the really bad ones, once a week but lived with the constant daily variety.
Canine studies show that in the body the drug converts into nordiazepam and oxa- zepam generic neurontin 400mg without prescription, which are also metabolites of diazepam cheap 300mg neurontin amex. With stronger dosages elderly persons sometimes experience difﬁculty in manual dexterity and other muscle control; during an experiment several elderly individuals fell purchase 100 mg neurontin otc. In an experiment some alcoholics had difﬁculty distinguish- ing halazepam from placebo, an outcome suggesting that the drug has low potential for abuse (as abusers of alcohol and other drugs should be particu- larly susceptible). Nonetheless, a person’s body can develop physical depen- dence with halazepam, which is a traditional sign of addictive potential. One group of researchers found withdrawal symptoms to be so mild, however, that a placebo could control them. The heartburn medicine cimetidine is suspected of inter- fering with halazepam’s effects. No cancer developed in rats and mice at daily dosage levels 5 to 50 times the maximum human dose. Experiments with rats and rabbits have produced no evidence that the drug causes birth defects. For most of the twentieth century drug addiction and heroin were synonymous in the United States; all substance abuse was assumed to lead to heroin. Only in the 1980s did heroin become displaced as the devil drug, supplanted in public fear and disapproval by cocaine. Being a Schedule I substance, heroin has no ofﬁcially approved medical use in the United States. Heroin is produced from morphine, and body chemistry converts a heroin dose back into morphine. One study of pain relief found heroin comparable to hydromorphone, a standard med- ication administered to ﬁght severe pain. Physicians have judged heroin to be a safe anesthetic for use during childbirth, with no apparent ill effect on mother or child. The drug is also used to treat porphyria, a body chemistry disorder making people sensitive to light and occasionally making them vio- lent. Heroin users of both genders have reported increased sexual activity upon starting the compound, with decline in that activity as usage continues. That sequence would be consistent with the drug at ﬁrst reducing psycholog- ical anxiety, an effect gradually evolving into indifference about the world. Extrapolating from severity of withdrawal symptoms, any particular size heroin dose taken by intravenous injection is ﬁve times stronger than one taken by inhaling heated vapor (“chasing the dragon”). Other measurements show a dose to be four times more potent when taken intravenously instead of by inhaling powder. Sometimes intravenous injection of heroin produces a rush of feeling lik- ened to a total body sexual orgasm. Heroin may allow some nonmedical users to experience euphoria, but more typically an intoxicating dose increases psy- Heroin 193 chic distance between the user and the world, making reality seem unimpor- tant. People using lesser doses of heroin in that way may function more productively, or they may experience trouble because they feel conﬁdent enough to get into situations they would otherwise avoid. Researchers ﬁnd, however, that injectors of a heroin variety called “black tar” have an increased risk for botulism infection at the injection site, no matter how hygienic their equipment and technique. Injectors of any type heroin are more prone to all sorts of infections, and some researchers suspect that heroin impairs the immune system. Inhaling heated heroin vapor can rapidly pro- duce enough brain damage to cripple a person, although case reports indicate that partial recovery is possible. Inhaling either the vapor or powder can also cause breathing trouble, and injection can cause swift ﬂuid buildup in the lungs. A study found reduced bone density in chronic male heroin users, making broken bones more likely, and researchers suspected the problem re- sulted from lower testosterone levels caused by heroin (a heroin action that is also known to reduce male sex drive). Apparently the bone density and testosterone problems can correct themselves if heroin use stops. Although stroke is an uncommonly reported outcome of heroin use, autopsy examina- tions of 100 heroin addict brains indicate that 5% to 10% of injectors suffer small strokes that may not cause the person to seek medical treatment but that may thereafter affect the person’s behavior. One experiment with heroin addicts found still another unwanted effect: Most of them see colors somewhat differently than nonusers do. All the above hazards are real, but experience also shows that addicts can take maintenance doses (enough to hold off withdrawal symptoms but not enough to get high) for years with no apparent ill effect. The behavior of people on a maintenance dose can be indistinguishable from someone using no drug at all; while on a maintenance dose of heroin ordinary middle-class persons can function well in all aspects of life at work and at home. When federal legislation outlawed the drug in the early twentieth century, the kinds of persons who took the drug changed, as did the common reasons for using the drug.
This is not surprising buy neurontin 800 mg without a prescription, given the importance of the receptor to the pharma- codynamic phase of drug action generic neurontin 300mg free shipping. Other molecular participants within this chain reaction order neurontin 100 mg with amex, such as kinases, are then activated. This cascade of events finally results in the physiological (and hopefully therapeutic) change attributed to the drug. The same mechanisms also operate with endogenous agents such as hormones and neurotransmitters. It is generally accepted that endogenous or exogenous agents interact specifically with a receptor site on a specialized receptor molecule. Drug interaction with this site of binding, which has chemical recognition properties, may or may not trigger the sequence of biochemical events discussed above; therefore, one must distinguish care- fully between sites of action (true receptors) and sites of binding (silent receptors or, occasionally, separate allosteric antagonist-binding sites). The notion was initially formulated by John Langley, a British physiologist who worked on the biological properties of atropine (2. However, the actual term receptor was first intro- duced in 1907 by Paul Ehrlich, the famous pioneer of chemotherapy and immunochem- istry. His concepts of receptor binding (corpora non agunt nisi fixata—“compounds do not act unless bound”), bioactivation, the therapeutic index, and drug resistance are still valid in principle, though they have undergone considerable expansion and refinement. True receptors, that is, those initiating a chain of physicochemical events leading to a pharmacological response, have a diverse molecular nature. Among the well-described receptors, several classes of receptor molecules may be distinguished: 1. Lipoproteins or glycoproteins are the macromolecules that most commonly form receptors. They are often firmly embedded in the plasma membrane or cell-organelle membrane as intrinsic proteins (see section 7. At times, this renders their isolation and subsequent functional reconstitution difficult, as their structure may be dependent upon the surrounding membrane. Isolation of such a receptor molecule may cause its structural collapse, even to the extent that specific binding properties are lost. Many drugs exert their effects by specifically affecting enzymes involved in vital biochemical reactions (see section 8. Cell membranes contain “protein icebergs floating in a sea of lipid,” and many drug molecules do interact with cell membranes. Lipids intimately envelop proteins and thus may profoundly influence their structure and function. When one starts to work with a new class of molecules or a new tissue, it is important to use an extensive set of criteria for receptor identification in both in vitro and in vivo studies. The receptor should be present in the tissues in quantities commensurate with established receptor concentrations (10–100 pmol/g). The binding of a drug to its receptor should be saturable, with a binding equilibrium constant in the nanomolar range. However, it must be borne in mind that saturability is not identical with specificity. Binding kinetics should be proportional to the rate of the in vivo response and should yield an equilibrium constant equal to the dissociation rate constant divided by the association rate constant. Wherever applicable, binding should be stereospecific; but the fulfilment of this cri- terion is not absolute proof that the site being investigated is a receptor. The receptor should be isolated from an organ or tissue relevant to the disease process under investigation. Hallucinogen binding to liver tissue, for example, is unlikely to indicate more than the presence of a metabolizing enzyme. It is desirable that the order of drug binding to a receptor preparation in a related series of drugs be the same as the order of their clinical or at least their in vivo activity. Failure to meet even one of these criteria jeopardizes the identification of the receptor. Even when all of the criteria are fulfilled, extreme caution in data interpretation is still mandatory. As discussed above, a macromolecule should be “worthy and capable of being targeted for drug design. A macromolecule that can be usefully attacked for purposes of drug design is termed a druggable target. As discussed earlier, covalent and noncovalent bonds are both based on electronic interactions but differ greatly in their stabilities, which are expressed in terms of bond dissociation energies. Although there is no direct correlation between drug–receptor binding energy and drug potency, the energy values provide an approximate estimate of the ease of formation, the ease of disruption, and the relative strengths of various intermolecular interaction types.
