Emergency treatment of cocaine-associated hyperthermia consists of administering a benzodiazepine sedation agent, such as diazepam (Valium) or lorazepam (Ativan) to enhance muscle relaxation and decrease sympathetic outflow from the central nervous system. Physical cooling is best accomplished with tepid water misting and cooling with a fan (convection and evaporation), which can be carried out easily in the field or hospital. There is no specific pharmacological antidote for cocaine overdose. The chest pain, high blood pressure, and increased heart rate caused by cocaine may be also treated with a benzodiazepine. Multiple and escalating dose of benzodiazepines may be necessary to achieve effect, which increases risk of over-sedation and respiratory depression. A comprehensive systematic review of all pharmacological treatments of cocaine cardiovascular toxicity revealed benzodiazepines may not always reliably lower heart rate and blood pressure.

Nitric-oxide mediated vasodilators, such as nitroglycerin and nitroprusside, are effective at lowering blood pressure and reversing coronary arterial vasoconstriction, but not heart rate. Nitroglycerin is useful for cocaine-induced chest pain, but the possibility of reflex tachycardia must be considered. Alpha-blockers such as phentolamine have been recommended and may be used to treat cocaine-induced hypertension and coronary arterial vasoconstriction, but these agents do not reduce heart rate. Furthermore, phentolamine is rarely used, not readily available in many emergency departments, and many present-day clinicians are unfamiliar with its use and titratability. Calcium channel blockers may also be used to treat hypertension and coronary arterial vasoconstriction, but fail to lower tachycardia based on all cocaine-related studies. Non-dihydropyridine calcium channels blockers such as diltiazem and verapamil are preferable, as dihydropyridine agents such as nifedipine have much higher risk of reflex tachycardia.

Agitated patients are best treated with benzodiazepines, but antipsychotics such as haloperidol and olanzapine may also be useful. The alpha-2 agonist dexmedetomidine may also be useful for treatment of agitation, but effects on heart rate and blood pressure are variable based on several studies and case reports. Lidocaine and intravenous lipid emulsion have been successfully used for serious ventricular tachyarrhythmias in several case reports.

The use of beta-blockers for cocaine cardiovascular toxicity has been subject to a relative contraindication by many clinicians for several years despite extremely limited evidence. The phenomenon of “unopposed alpha-stimulation,” in which blood pressure increases or coronary artery vasoconstriction worsens after blockade of beta-2 vasodilation in cocaine-abusing patients, is controversial. This rarely-encountered and unpredictable adverse effect has resulted in some clinicians advocating for an absolute contraindication of the use of all beta-blockers, including specific, non-specific, and mixed. Many clinicians have disregarded this dogma and administer beta-blockers for cocaine-related chest pain and acute coronary syndrome, especially when there is demand ischemia from uncontrolled tachycardia. Of the 1,744 total patients identified in the aforementioned systematic review, only 7 adverse events were from putative cases of “unopposed alpha-stimulation” due to propranolol (n=3), esmolol (n=3), and metoprolol (n=1). Some detractors of beta-blockers for cocaine-induced chest pain have cited minimal acute mortality and the short half-life of the drug, making it unnecessary to aggressively treat any associated tachycardia and hypertension. However, the long-term effect of cocaine use and development of heart failure, with early mortality, high morbidity, and tremendous demand on hospital utilization should be taken under consideration.

The mixed beta/alpha blocker labetalol has been shown to be safe and effective for treating concomitant cocaine-induced hypertension and tachycardia, without any “unopposed alpha-stimulation” adverse events recorded. The use of labetalol is approved by a recent AHA/ACC guideline for cocaine and methamphetamine patients with unstable angina/non-STEMI.

The side effects of penicillin can be altered by taking other medications at the same time. Taking oral contraceptives along with penicillin may lower the effects of the contraceptive. When probenecid is used concurrently with penicillin, kidney excretion of probenecid is increase resulting in higher blood levels of penicillin in the circulation. In some instances, this would be intended therapeutic effect. In other instances, this is an unintended side effect. Neomycin can lower the absorption of penicillin from the gastrointestinal tract resulting in lower than expected levels of penicillin in the circulation. This side effect may result in an ineffective therapeutic effect of penicillin. When methotrexate is administered with penicillin, toxicity may occur related to methotrexante.

Some drugs, such as the prokinetic agents increase the speed with which a substance passes through the intestines. If a drug is present in the digestive tract's absorption zone for less time its blood concentration will decrease. The opposite will occur with drugs that decrease intestinal motility.

- pH: Drugs can be present in either ionised or non-ionised form, depending on their pKa (pH at which the drug reaches equilibrium between its ionised and non-ionised form). The non-ionized forms of drugs are usually easier to absorb, because they will not be repelled by the lipidic bylayer of the cell, most of them can be absorbed by passive diffusion, unless they are too big or too polarized (like glucose or vancomicyn), in which case they may have or not specific and non specific transporters distributed on the entire intestine internal surface, that carries drugs inside the body. Obviously increasing the absorption of a drug will increase its bioavailability, so, changing the drug's state between ionized or not, can be useful or not for certain drugs.

Certain drugs require an acid stomach pH for absorption. Others require the basic pH of the intestines. Any modification in the pH could change this absorption. In the case of the antacids, an increase in pH can inhibit the absorption of other drugs such as zalcitabine (absorption can be decreased by 25%), tipranavir (25%) and amprenavir (up to 35%). However, this occurs less often than an increase in pH causes an increase in absorption. Such as occurs when cimetidine is taken with didanosine. In this case a gap of two to four hours between taking the two drugs is usually sufficient to avoid the interaction.

- Drug solubility: The absorption of some drugs can be drastically reduced if they are administered together with food with a high fat content. This is the case for oral anticoagulants and avocado.

- Formation of non-absorbable complexes:

- Chelation: The presence of di- or trivalent cations can cause the chelation of certain drugs, making them harder to absorb. This interaction frequently occurs between drugs such as tetracycline or the fluoroquinolones and dairy products (due to the presence of Ca).

- Binding with proteins. Some drugs such as sucralfate binds to proteins, especially if they have a high bioavailability. For this reason its administration is contraindicated in enteral feeding.

- Finally, another possibility is that the drug is retained in the intestinal lumen forming large complexes that impede its absorption. This can occur with cholestyramine if it is associated with sulfamethoxazol, thyroxine, warfarin or digoxin.

- Acting on the P-glycoprotein of the enterocytes: This appears to be one of the mechanisms promoted by the consumption of grapefruit juice in increasing the bioavailability of various drugs, regardless of its demonstrated inhibitory activity on first pass metabolism.

When penicillin is used at high doses hypokalemia, metabolic acidosis, and hyperkalemia can occur. Developing hypernatremia after administering high doses of penicillin can be a serious side effect.

Among US adults older than 55, 4% are taking medication and or supplements that put them at risk of a major drug interaction. Potential drug-drug interactions have increased over time and are more common in the low educated elderly even after controlling for age, sex, place of residence, and comorbidity.

Behavioral tolerance occurs with the use of certain psychoactive drugs, where tolerance to a behavioral effect of a drug, such as increased motor activity by methamphetamine, occurs with repeated use; it may occur through drug-independent learning or as a form of pharmacodynamic tolerance in the brain; the latter mechanism of behavioral tolerance occurs when one learns how to actively overcome drug-induced impairment through practice. Behavioral tolerance is often context-dependent, meaning tolerance depends on the environment in which the drug is administered, and not on the drug itself. Behavioral sensitization describes the opposite phenomenon.

Since the mutation is a genetic issue, there is currently no cure for the flush reaction. Clinicians and the East Asian public generally know about the alcohol flushing response. Prevention would include not drinking alcohol.

Ipecac or ipecacuanha consists of the dried rhizome and roots of "Cephaelis ipecacuanha".

The medical virtues of ipecac are almost entirely due to the action of its alkaloids-emetine and cephaline. Till today, emetine remains one of the best drugs for treating amoebic liver abscess. It has a direct action on the trophozoites.

Its greater concentration and duration of action in the liver as compared to that in the intestinal wall explains its high efficacy in amoebic liver abscess and also its low parasitic cure rate for intestinal amoebiasis.

The drug is detoxicated and eliminated slowly. It may, therefore, produce cumulative effects. In man, emetine poisoning is characterized by muscular tremors, weakness and pain in the extremities which tend to persist until drug administration is stopped. Gastro-intestinal symptoms include nausea, vomiting and bloody diarrhoea. The latter may be mistaken for a recurrence of amoebic dysentery.

Many clinicians fear the occurrence of cardiac toxicity due to this drug and hence avoid using it. Serious cardiac toxicity, however, is rare. Both recovered with the treatment for heart failure and withdrawal of emetine. One patient who was given fifteen injections of emetine in a dose of 60 mgm per day, died.

Overdosage of emetine produces focal necrosis of cardiac muscle resulting in cardiac failure and sudden death.

Emetine, like digitalis may produce mild ST and T wave changes in the electrocardiogram which does not necessarily mean serious toxicity. In fact, they are encountered, though less commonly, after the use of chloroquine and metronidazole as well.

Toxic effects on the myocardium have been described even in doses generally considered safe. These are rise in pulse rate, fall in systolic blood pressure and ST-T changes in the electrocardiogram.

The other rare E.C.G. changes include deformity of QRS complexes, prolongation of PR interval, atrial premature beats, and atrial tachycardia. In adults, fatal cases have been reported with a total dose of 0.6 G. or less. The incidence of toxic heart damage greatly increases in patients with anaemia.

In patients having myocardial disease or marked hypertension, emetine can be used for amoebic liver abscess, as the benefits from it may outweigh possible hazards. This situation is unlikely to arise these days, as equally good alternative drugs like metronidazole are available. Patients receiving emetine should be monitored for changes in pulse, blood pressure and electrocardiography. Absolute bed rest during and several days after emetine therapy has been recommended, although we have often seen patients in whom no untoward reactions have occurred in spite of neglecting the above precaution.

Theoretically the use of emetine in children is not advised. However, in practice it has been used as discussed elsewhere. It should not be administered during pregnancy unless absolutely necessary.

Although emetine is undeniably moderately toxic, the risk of using it would be worth accepting in such a serious illness were it not for the fact that less toxic drugs like chloroquine and metronidazole are now available.

In practice, emetine still produces a more dramatic clinical response thanchloroquine or metronidazole. This point would score in favour of emetine in places where facilities for a proper diagnosis are not available and a therapeutic test remains as the only weapon with a practitioner.

Emetine should always be given deep intramuscularly or deep subcutaneously but never intravenously. The total dose in amoebic liver abscess should not exceed 650 mg or 10 mg/kg. This should be given over a period of 10 days in a dose of 6G65 mg. daily. A relapse rate of 7% follows one such course. Therefore, the treatment could be repeated after a period of 2–6 weeks. Of late such a need does not arise, as drug combinations are commonly used. When parenteral emetine is combined with oral chloroquine or two courses of emetine are given, the relapse rate can be brought down to 1 percent.

It is a synthetic compound developed by Osbond "et al." and Brossi "et al." in 1959. It is as effective as emetine in its amoebicidal properties. Given parenterally dehydroemetine is surprisingly painless. Oral tablets have been introduced. But for some reason, these tablets have not become popular. A high cure rate can be obtained with this drug. Compared to emetine, its concentration in the heart is less. Electrocardiographic changes are not seen so often. When present, they are more transient than with emetine.

Dehydroemetine is excreted by the kidneys, heart and the other organs more rapidly than emetine. Therefore, a daily dose of 1.25 mg or 1.5 mg/kg body weight is necessary. The total daily dose should not exceed 90 mg. The course should not be repeated in less than 14 days.

Ondansetron, a 5HT3 antagonist, appears to have promise as a treatment.

Alcoholics may also require treatment for other psychotropic drug addictions and drug dependences. The most common dual dependence syndrome with alcohol dependence is benzodiazepine dependence, with studies showing 10–20 percent of alcohol-dependent individuals had problems of dependence and/or misuse problems of benzodiazepine drugs such as valium or clonazopam. These drugs are, like alcohol, depressants. Benzodiazepines may be used legally, if they are prescribed by doctors for anxiety problems or other mood disorders, or they may be purchased as illegal drugs "on the street" through illicit channels. Benzodiazepine use increases cravings for alcohol and the volume of alcohol consumed by problem drinkers. Benzodiazepine dependency requires careful reduction in dosage to avoid benzodiazepine withdrawal syndrome and other health consequences. Dependence on other sedative-hypnotics such as zolpidem and zopiclone as well as opiates and illegal drugs is common in alcoholics. Alcohol itself is a sedative-hypnotic and is cross-tolerant with other sedative-hypnotics such as barbiturates, benzodiazepines and nonbenzodiazepines. Dependence upon and withdrawal from sedative-hypnotics can be medically severe and, as with alcohol withdrawal, there is a risk of psychosis or seizures if not managed properly.

In cases of suspected copper poisoning, penicillamine is the drug of choice, and dimercaprol, a heavy metal chelating agent, is often administered. Vinegar is not recommended to be given, as it assists in solubilizing insoluble copper salts. The inflammatory symptoms are to be treated on general principles, as are the nervous ones.

There is some evidence that alpha-lipoic acid (ALA) may work as a milder chelator of tissue-bound copper. Alpha lipoic acid is also being researched for chelating other heavy metals, such as mercury.

Pharmacokinetics refers to the absorption, distribution, metabolism, and excretion of drugs. All psychoactive drugs are first absorbed into the bloodstream, carried in the blood to various parts of the body including the site of action (distribution), broken down in some fashion (metabolism), and ultimately removed from the body (excretion). All of these factors are very important determinants of crucial pharmacological properties of a drug, including its potency, side effects, and duration of action.

Pharmacokinetic tolerance (dispositional tolerance) occurs because of a decreased quantity of the substance reaching the site it affects. This may be caused by an increase in induction of the enzymes required for degradation of the drug e.g. CYP450 enzymes. This is most commonly seen with substances such as ethanol.

This type of tolerance is most evident with oral ingestion, because other routes of drug administration bypass first-pass metabolism. Enzyme induction is partly responsible for the phenomenon of tolerance, in which repeated use of a drug leads to a reduction of the drug’s effect. However, it is only one of several mechanisms leading to tolerance.

Surgical excision of fatty tissue deposits around joints (liposuction) has been used in some cases. It may temporarily relieve symptoms although recurrences often develop.

Traditional analgesics

The pain in Dercum's disease is often reported to be refractory to analgesics and to non-steroidal anti-inflammatory drugs (NSAIDs). However, this has been contradicted by the findings of Herbst et al. They reported that the pain diminished in 89% of patients (n=89) when treated with NSAIDs and in 97% of patients when treated with narcotic analgesics (n=37). The dosage required and the duration of the pain relief are not precisely stated in the article.

Lidocaine

An early report from 1934 showed that intralesional injections of procaine (Novocain®) relieved pain in six cases. More recently, other types of local treatment of painful sites with lidocaine patches (5%) (Lidoderm®) or lidocaine/prilocaine (25 mg/25 mg) cream (EMLA®) have shown a reduction of pain in a few cases.

In the 1980s, treatment with intravenous infusions of lidocaine (Xylocaine®) in varying doses was reported in nine patients. The resulting pain relief lasted from 10 hours to 12 months. In five of the cases, the lidocaine treatment was combined with mexiletine (Mexitil®), which is a class 1B anti-arrhythmic with similar pharmacological properties as lidocaine.

The mechanism by which lidocaine reduces pain in Dercum's disease is unclear. It may block impulse conduction in peripheral nerves, and thereby disconnect abnormal nervous impulse circuits. Nonetheless, it might also depress cerebral activity that could lead to increased pain thresholds. Iwane et al. performed an EEG during the administration of intravenous lidocaine. The EEG showed slow waves appearing 7 minutes after the start of the infusion and disappearing within 20 minutes after the end of the infusion. On the other hand, the pain relief effect was the greatest at about 20 minutes after the end of the infusion.

Based on this, the authors concluded that the effect of lidocaine on peripheral nerves most likely explains why the drug has an effect on pain in Dercum's disease. In contrast, Atkinson et al. have suggested that an effect on the central nervous system is more likely, as lidocaine can depress consciousness and decrease cerebral metabolism. In addition, Skagen et al. demonstrated that a patient with Dercum's disease lacked the vasoconstrictor response to arm and leg lowering, which indicated that the sympathicusmediated local veno-arteriolar reflex was absent. This could suggest increased sympathetic activity. An infusion of lidocaine increased blood flow in subcutaneous tissue and normalised the vasoconstrictor response when the limbs were lowered. The authors suggested that the pain relief was caused by a normalisation of up-regulated sympathetic activity.

Methotrexate and infliximab

One patient's symptoms were improved with methotrexate and infliximab. However, in another patient with Dercum's disease, the effect of methotrexate was discreet. The mechanism of action is unclear. Previously, methotrexate has been shown to reduce neuropathic pain caused by peripheral nerve injury in a study on rats. The mechanism in the rat study case was thought to be a decrease in microglial activation subsequent to nerve injury. Furthermore, a study has shown that infliximab reduces neuropathic pain in patients with central nervous system sarcoidosis. The mechanism is thought to be mediated by tumour necrosis factor inhibition.

Interferon α-2b

Two patients were successfully treated with interferon α-2b. The authors speculated on whether the mechanism could be the antiviral effect of the drug, the production of endogenous substances, such as endorphins, or interference with the production of interleukin-1 and tumour necrosis factor. Interleukin-1 and tumour necrosis factor are involved in cutaneous hyperalgesia.

Corticosteroids

A few patients noted some improvement when treated with systemic corticosteroids (prednisolone), whereas others experienced worsening of the pain. Weinberg et al. treated two patients with juxta-articular Dercum's disease with intralesional injections of methylprednisolone (Depo-Medrol). The patients experienced a dramatic improvement.

The mechanism for the pain-reducing ability of corticosteroids in some conditions is unknown. One theory is that they inhibit the effects of substances, such as histamine, serotonin, bradykinin, and prostaglandins. As the aetiology of Dercum's disease is probably not inflammatory, it is plausible that the improvement some of the patients experience when using corticosteroids is not caused by an anti-inflammatory effect.

Several health authorities have issued related guidance documents, which need to be considered for drug development:

Hiccups are normally waited out, as any fit of them will usually pass quickly. Folkloric 'cures' for hiccups are common and varied, but no effective standard for stopping hiccups has been documented. Hiccups are treated medically only in severe and persistent (termed "intractable") cases.

Numerous medical remedies exist but no particular treatment is known to be especially effective. Many drugs have been used, such as baclofen, chlorpromazine, metoclopramide, gabapentin, and various proton-pump inhibitors. Hiccups that are secondary to some other cause like gastroesophageal reflux disease or esophageal webs are dealt with by treating the underlying disorder. The phrenic nerve can be blocked temporarily with injection of 0.5% procaine, or permanently with bilateral phrenicotomy or other forms of surgical destruction. Even this rather drastic treatment does not cure some cases, however.

An anecdotal medical approach is to install lidocaine liniment 3% or gel 2% into the ear canal. Somehow this creates a vagus nerve-triggering reflex through its extensions to the external ear and tympanus (ear drum). The effect can be immediate, and also have lasting effect after the lidocaine effect expires after about two hours.

Haloperidol (Haldol, an anti-psychotic and sedative), metoclopramide (Reglan, a gastrointestinal stimulant), and chlorpromazine (Thorazine, an anti-psychotic with strong sedative effects) are used in cases of intractable hiccups. Effective treatment with sedatives often requires a dose that renders the person either unconscious or highly lethargic. Hence, medicating with sedatives is only appropriate short-term, as the affected individual cannot continue with normal life activities while under their effect.

Persistent digital rectal massage has also been proven effective in terminating intractable hiccups.

The administration of intranasal vinegar was found to ease the chronic and severe hiccups of a three-year-old Japanese girl. Vinegar may stimulate the dorsal wall of the nasopharynx, where the pharyngeal branch of the glossopharyngeal nerve (the afferent of the hiccup reflex arc) is located.

Bryan R. Payne, a neurosurgeon at the Louisiana State University Health Sciences Center in New Orleans, has had some success with an experimental procedure in which a vagus nerve stimulator is implanted in the upper chest of patients with an intractable case of hiccups. "It sends rhythmic bursts of electricity to the brain by way of the vagus nerve, which passes through the neck. The Food and Drug Administration approved the vagus nerve stimulator in 1997 as a way to control seizures in some patients with epilepsy."

Lockhart stated that hiccups can sometimes be cured by pinching the skin that covers the surface of the deltoid muscles, which is supplied by the axillary nerve which shares the c5 nerve root with the phrenic nerve.

In terms of the treatment for ativated PI3K delta syndrome, generally primary immunodeficiencies see the following used:

- Bacterial infection should be treated rapidly(with antibiotics)

- Antiviral therapy

- Modify lifestyle(exposure to pathogens need to be minimized)

Within all classes of medicinal drugs that possibly can lead to pulmonary toxicity as a side effect, most pulmonary toxicity is due to chemotherapy for cancer.

Many medicinal drugs can lead to pulmonary toxicity. A few medicinal drugs can lead to pulmonary toxicity frequently (in medicine defined by international regulatory authorities such as the U.S. Food and Drug Administration and the EMEA [European Union] as > 1% and 10%). These medicinal drugs can include gold and nitrofurantoin, as well as the following drugs used in chemotherapy for cancer: Methotrexate, the taxanes (paclitaxel and docetaxel), gemcitabine, bleomycin, mitomycin C, busulfan, cyclophosphamide, chlorambucil, and nitrosourea (e.g., carmustine).

Also, some medicinal drugs used in cardiovascular medicine can lead to pulmonary toxicity frequently or very frequently. These include above all amiodarone, as well as beta blockers, ACE inhibitors (however, pulmonary toxicity of ACE inhibitors usually lasts only 3–4 months and then usually disappears by itself), procainamide, quinidine, tocainide, and minoxidil.

Both oncologists and cardiologists are well aware of possible pulmonary toxicity.

Alcohol flush reaction is a condition in which an individual develops flushes or blotches associated with erythema on the face, neck, shoulders, and in some cases, the entire body after consuming alcoholic beverages. The reaction is the result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol, and is caused by an acetaldehyde dehydrogenase deficiency.

This syndrome has been associated with an increased risk of esophageal cancer in those who drink. It has also been associated with lower than average rates of alcoholism, possibly due to its association with adverse effects after drinking alcohol.

Approximately 36% of East Asians (Japanese, Koreans, Vietnamese and Chinese) show characteristic physiological responses to drinking alcohol that includes facial flushing, nausea, headaches and tachycardia.

Psychotoxicity in pharmacology is the effect when a drug interferes seriously with normal behaviour.

Cookware in which copper is the main structural element (as opposed to copper clad, copper sandwiched or copper colored) is sometimes manufactured without a lining when intended to be used for any of a number of specific culinary tasks, such as preparing preserves or meringues. Otherwise, copper cookware is lined with a non-reactive metal to prevent contact between acidic foods and the structural copper element of the cookware.

Excepting for acute or chronic conditions, exposure to copper in cooking is generally considered harmless. Following Paracelsus, dosage makes the poison; as this pertains to copper "a defense mechanism has apparently evolved as a consequence of which toxicity in man is very unusual."

Acute exposure and attendant copper toxicity is possible when cooking or storing highly acidic foods in unlined copper vessels for extended periods, or by exposing foodstuffs to reactive copper salts (copper corrosion, or verdigris). Continuous, small ("chronic") exposures of acidic foods to copper may also result in toxicity in cases where either surface area interaction potentials are significant, pH is exceptionally low and concentrated (in the case of cooking with, for example, vinegar or wine), or both, and insufficient time elapses between exposures for normal homeostatic elimination of excess copper.

Exceptions to the above may be observed in the case of jam, jelly and preserve -making, wherein unlined copper vessels are used to cook (not to store) acidic preparations, in this case of fruit. Methods of jamming and preserving specify sugar as chemically necessary to the preserving (antibacterial) action, which has the additional effect of mediating (buffering) the interaction of fruit acid with copper, permitting the use of the metal for its efficient thermal transfer properties.

The "medical benefit-cost ratio" for the patient should be kept in mind. Medicinal drugs should not be ruled out completely right from the start just because they possibly could cause pulmonary toxicity. A number of medicinal drugs that could cause pulmonary toxicity can be life-saving for certain patients with specific diseases. For example, amiodarone falls into this category. Ideally, the pros and cons should be weighed at the start of therapy and in regular intervals thereafter, based on the available scientific/medical evidence, by an expert physician, together with an informed patient.

There are many superstitious and folk remedies for hiccups, including headstanding, drinking a glass of water upside-down, being frightened by someone, breathing into a bag, and eating a large spoonful of peanut butter. Placing sugar on or under the tongue has also been used.

A simple treatment involves increasing the partial pressure of CO and inhibiting diaphragm activity by holding one’s breath or rebreathing into a paper bag. Other potential remedies suggested by NHS Choices include pulling your knees up to your chest and leaning forward, sipping ice-cold water and swallowing some granulated sugar.

In Plato's "Symposium", Aristophanes has a case of the hiccups and is advised by Eryximachus, a physician, to cure them by holding his breath, or, failing that, by gargling or provoking sneezing. This ancient recommendation can be compared with the vagus nerve stimulation techniques mentioned previously.

3T3 Neutral Red Phototoxicity Test – An in vitro toxicological assessment test used to determine the cytotoxic and photo(cyto)toxicity effect of a test article to murine fibroblasts in the presence or absence of UVA light.

"The 3T3 Neutral Red Uptake Phototoxicity Assay (3T3 NRU PT) can be utilized to identify the phototoxic effect of a test substance induced by the combination of test substance and light and is based on the comparison of the cytotoxic effect of a test substance when tested after the exposure and in the absence of exposure to a non-cytotoxic dose of UVA/vis light. Cytotoxicity is expressed as a concentration-dependent reduction of the uptake of the vital dye - Neutral Red.

Substances that are phototoxic in vivo after systemic application and distribution to the skin, as well as compounds that could act as phototoxicants after topical application to the skin can be identified by the test. The reliability and relevance of the 3T3 NRU PT have been evaluated and has been shown to be predictive when compared with acute phototoxicity effects in vivo in animals and humans."
