Inhalants: From 1 Different Sources

Substances that can be inhaled into the body through the lungs. They may be delivered in traditional form dissolved in hot water and inhaled in the steam, or as an aerosol – a suspension of very small liquid or solid particles in the air. The latter are now usually delivered by devices in which the aerosol is kept under pressure in a small hand-held cylinder and delivered in required doses by a release mechanism.

Aerosols Asthmatic patients (see ASTHMA) ?nd aerosol devices to be of value in controlling their attacks. They provide an e?ective and convenient way of applying drugs directly to the bronchi, thus reducing the risks of unwanted effects accompanying SYSTEMIC therapy. BRONCHODILATOR aerosols contain either a beta-sympathomimetic agent or ipratropium bromide, which is an ANTICHOLINERGIC drug.

ISOPRENALINE was the ?rst compound to be widely used as an aerosol. It did however stimulate beta1 receptors in the heart as well as beta2 receptors in the bronchi, and so produced palpitations and even dangerous cardiac arrhythmias. Newer beta-adrenoceptor agonists are speci?c for the beta2 receptors and thus have a greater safety margin. They include SALBUTAMOL, TERBUTALINE, rimiterol, fenoterol and reproterol. Unwanted effects such as palpitations, tremor and restlessness are uncommon with these, more speci?c preparations. In patients who get insu?cient relief from the beta-adrenoreceptor agonist, the drug ipratropium bromide is worth adding. Salmeterol is a longer-acting choice for twice-daily administration: it is not intended for the relief of acute attacks, for which shorter-acting beta2 stimulants such as salbutamol should be used. Salmeterol should be added to existing corticosteroid therapy (see CORTICOSTEROIDS), rather than replacing it.

Patients must be taught carefully and observed while using their inhalers. It is important for them to realise that if the aerosol no longer gives more than slight transient relief, they should not increase the dose but seek medical help.

Aerosol

See INHALANTS.... aerosol

Inhaler

A mechanism for administering a drug in the form of a powder or aerosol. mainly used by patients with ASTHMA. Inhalers are basically of two types: aerosol, and dry-powder inhaler. The former delivers the drug as an aerosol spray when the patient presses the top of the canister containing the drug; the latter works by putting a drug capsule in the end of the chamber and, when the patient presses the top, the capsule is pierced and the drug released. A variety of ‘spacing devices’ are available to use with pressurised (aerosol) inhalers, providing metered doses. The space introduced between the inhaler and the mouth reduces the velocity of the aerosol and thus the impact it has on the oropharynx. More time is therefore allowed for evaporation of the propellant, with a greater concentration of drug particles being inhaled. Inhalers with larger spacing devices and a one-way valve are very e?ective and particularly useful for children and patients needing higher doses of the drug. (See INHALANTS; NEBULISERS.)... inhaler

Nasal Congestion

The nose and nasal sinuses (see SINUS) produce up to a litre of MUCUS in 24 hours, most of which enters the stomach via the NASOPHARYNX. Changes in the nasal lining mucosa occur in response to changes in humidity and atmospheric temperature; these may cause severe congestion, as might an allergic reaction or nasal polyp.

Treatment Topical nasal decongestants include sodium chloride drops and corticosteroid nasal drops (for polyps). For commoncold-induced congestion, vapour inhalants, decongestant sprays and nasal drops, including EPHEDRINE drops, are helpful. Overuse of decongestants, however, can produce a rebound congestion, requiring more treatment and further congestion, a tiresome vicious circle. Allergic RHINITIS (in?ammation of the nasal mucosa) usually responds to ipratropium bromide spray.

Systemic nasal decongestants given by mouth are not always as e?ective as topical administrations but they do not cause rebound congestion. Pseudoephedrine hydrochoride is available over the counter, and most common-cold medicines contain anticongestant substances.... nasal congestion

Nebulisers

A nebuliser makes an aerosol (see under INHALANTS) by blowing air or oxygen through a solution of a drug. Many inhaled drugs such as SALBUTAMOL, ipratropium and beclomethasone can be given in this way. It has the advantage over a metered dose inhaler (MDI) that no special e?ort is required to coordinate breathing, and a nebuliser allows a much greater volume of the drug to be delivered to where it is needed (the airways) compared with that of MDIs. The use of higher doses of bronchodilator drugs made possible by the nebuliser means that the risk of unwanted side-effects is also increased. Fortunately the safety pro?le of anti-asthmatic drugs such as salbutamol is extremely high and overdose is generally well-tolerated.... nebulisers

Bronchiectasis

Damage to bronchi when ballooned beyond normal limits, usually from chronic infection. May be a legacy from lung infections, whooping cough, measles, tuberculosis, foreign body or other bronchial troubles. Predisposing factors: smoking, working with asbestos and other industrial materials. Now known that some structural changes in bronchial epithelium caused by cigarette smoking are reversible by abstinence for over two years.

A plug of tenacious mucus may be clogged in the bronchial tree and gradually sucked into the smaller bronchi, blocking them. This prevents air from passing through to replace air that has been absorbed and precipitates cough, sputum, spitting of blood. A stethoscope reveals crepitations; chronic cases may be detected by clubbing of the fingers, which sign may be missing in bronchitis and other chest infections. Alternatives. Treatment. Bronchitics are most at risk and should never neglect a cold. Stimulating expectorants followed by postural drainage indicated. To control infection, plenty of Echinacea should be given. Where a localised area becomes septic a surgical lobectomy may be necessary. See: POSTURAL DRAINAGE. Cases of developed bronchiectasis can be maintained relatively well over a period of years by judicious use of herbs: Bayberry bark, Blood root, Elecampane root, Ephedra, Eucalyptus oil, Grindelia, Senega root, Mullein, Pleurisy root, Red Clover. Lobelia. Not Comfrey.

Dosage

Many factors in?uence the activity with which drugs operate. Among the factors which affect the necessary quantity are age, weight, sex, idiosyncrasy, genetic disorders, habitual use, disease, fasting, combination with other drugs, the form in which the drug is given, and the route by which it is given.

Normally, a young child requires a smaller dose than an adult. There are, however, other factors than age to be taken into consideration. Thus, children are more susceptible than adults to some drugs such as MORPHINE, whilst they are less sensitive to others such as ATROPINE. The only correct way to calculate a child’s dose is by reference to texts supplying a recommended dose in milligrams per kilogram. However, many reference texts simply quote doses for certain age-ranges.

Old people, too, often show an increased susceptibility to drugs. This is probably due to a variety of factors, such as decreased weight; diminished activity of the tissues and therefore diminished rate at which a drug is utilised; and diminished activity of the KIDNEYS resulting in decreased rate of excretion of the drug.

Weight and sex have both to be taken into consideration. Women require slightly smaller doses than men, probably because they tend to be lighter in weight. The e?ect of weight on dosage is partly dependent on the fact that much of the extra weight of a heavy individual is made up of fatty tissue which is not as active as other tissues of the body. In practice, the question of weight seldom makes much di?erence unless the individual is grossly over- or underweight.

Idiosyncrasy occasionally causes drugs administered in the ordinary dose to produce unexpected effects. Thus, some people are but little affected by some drugs, whilst in others, certain drugs – for example, psychoactive preparations such as sedatives – produce excessive symptoms in normal or even small doses. In some cases this may be due to hypersensitivity, or an allergic reaction, to the drug, which is a possibility that must always be borne in mind

(e.g. with PENICILLIN). An individual who is known to be allergic to a certain medication is strongly advised to carry a card to this e?ect, and always to inform medical and dental practitioners and/or a pharmacist before accepting a new prescription or buying an over-the-counter preparation.

Habitual use of a drug is perhaps the in?uence that causes the greatest increase in the dose necessary to produce the requisite e?ect. The classical example of this is with OPIUM and its derivatives.

Disease may modify the dose of medicines. This can occur in several ways. Thus, in serious illnesses the patient may be more susceptible to drugs, such as narcotics, that depress tissue activity, and therefore smaller doses must be given. Again, absorption of the drug from the gut may be slowed up by disease of the gut, or its e?ect may be enhanced if there is disease of the kidneys, interfering with the excretion of the drug.

Fasting aids the rapidity of absorption of drugs, and also makes the body more susceptible to their action. Partly for this reason, as well as to avoid irritation of the stomach, it is usual to prescribe drugs to be taken after meals, and diluted with water.

Combination of drugs is to be avoided if possible as it is often di?cult to assess what their combined e?ect may be. In some cases they may have a mutually antagonistic e?ect, which means that the patient will not obtain full bene?t. Sometimes a combination may have a deleterious e?ect.

Form, route and frequency of administration Drugs are now produced in many forms, though tablets are the most common and, usually, convenient. In Britain, medicines are given by mouth whenever possible, unless there is some degree of urgency, or because the drug is either destroyed in, or is not absorbed from, the gut. In these circumstances, it is given intravenously, intra-muscularly or subcutaneously. In some cases, as in cases of ASTHMA or BRONCHITIS, the drug may be given in the form of an inhalant (see INHALANTS), in order to get the maximum concentration at the point where it is wanted: that is, in the lungs. If a local e?ect is wanted, as in cases of diseases of the skin, the drug is applied topically to the skin. In some countries there is a tendency to give medicines in the form of a suppository which is inserted in the rectum.

Recent years have seen developments whereby the assimilation of drugs into the body can be more carefully controlled. These include, for example, what are known as transdermals, in which drugs are built into a plaster that is stuck on the skin, and the drug is then absorbed into the body at a controlled rate. This method is now being used for the administration of GLYCERYL TRINITRATE in the treatment of ANGINA PECTORIS, and of hyoscine hydrobromide in the treatment of MOTION (TRAVEL) SICKNESS. Another is a new class of implantable devices. These are tiny polymers infused with a drug and implanted just under the skin by injection. They can be tailored so as to deliver drugs at virtually any rate – from minutes to years. A modi?cation of these polymers now being investigated is the incorporation of magnetic particles which allow an extra burst of the incorporated drug to be released in response to an oscillating magnetic ?eld which is induced by a magnetic ‘watch’ worn by the patient. In this way the patient can switch on an extra dose of drug when this is needed: insulin, for instance, in the case of diabetics. In yet another new development, a core of drug is enclosed in a semi-permeable membrane and is released in the stomach at a given rate. (See also LIPOSOMES.)... dosage

Inhalation

A method of applying drugs in a ?nely divided or gaseous state, so that, when breathed in, they may come into contact with the nose, throat and lungs. There are two chief means by which drugs are mingled with the air and so taken in by breathing: these are traditional steam inhalations, and modern aerosol devices which deliver a ?ne spray direct into the mouth. (See INHALANTS; INHALER.)... inhalation

Terbutaline

A beta2 adrenoreceptor agonist that acts as a BRONCHODILATOR (see also BETAADRENOCEPTOR-BLOCKING DRUGS). As an aerosol (see INHALANTS), it is of particular value in the treatment of mild to moderate attacks of ASTHMA; it is also available in oral and parenteral forms, as well as subcutaneous, intramuscular, or slow intravenous injection.... terbutaline

Inhalations

Herbs containing essential oils are sometimes used as inhalations. 1oz (30g) herb is infused in 2 pints (one and a quarter litres) boiling water for 15 minutes, strained, and the steam inhaled with the aid of a towel above the head. Soothing to irritable and sensitive mucous surfaces. Anti- microbial effects on colds, whooping cough, croup, laryngitis, coryza, asthma and early stages of fevers. To relieve spasm of bronchioles: Lobelia, Stramonium, Eucalyptus, Aloe Vera.

Important inhalants: Eucalyptus, Thyme, Hyssop, Rosemary, Lavender, Chamomile, Mint, Tea Tree. Aromatherapy offers oils of the above herbs: 6-12 drops floated on the surface of 2 pints boiling water after being allowed to stand 3 minutes. See: FRIAR’S BALSAM. TEA TREE.

Alternative method. In place of a basin use an aluminium hot water bottle into which boiling water is poured. Add few drops Friar’s Balsam, Olbas, or essential oil. Insert a large funnel into which the mouth and nose are placed to breathe the vapour. Stop up any free space in the neck of the bottle with a tissue. Camphorated oil. 4 teaspoons to litre boiling water. Inhale steam with aid of a towel over head.

Inhalant Salve for nasal congestion and frontal sinusitis. Oil Pine 1ml; Oil Eucalyptus 2ml; Oil Peppermint 2ml; Vaseline to 30 grams. Melt the Vaseline. Add oils. Stir until cold. For direct use or inhaled from boiling water. (F. Fletcher Hyde, FNIMH)

Essential Oils

Volatile oils. Out of 250,000 flowering plants only 2,000 yield essential oils. Soluble in alcohol, colourless. Contained in plants, they are responsible for taste, aroma and medicinal action. Organic properties give the flower its scent. May be anti-bacterial, antispasmodic, sedative, expectorant, antiseptic, anti-inflammatory. The smell of a flower roughly conveys the potency of its oil. An example is menthol in the mint family.

Oils used in Phytotherapy: Almond, English Chamomile, Aniseed, Bergamot, Black Pepper, Buchu, Camphor, Cedarwood, Cloves, Coriander, Cypress, Eucalyptus, Geranium, Juniper, Lavender (French), Lavender (English), Lavender (Spanish), Lemon, Marjoram, Orange (sweet), Patchouli, Peppermint, Pine (Scots), Rosemary, Sage, Sandalwood, Thyme, Spearmint, St John’s Wort, Turpentine, Ylang Ylang.

Most oils are obtained by steam distillation. Being highly concentrated, internal use is by a few drops, diluted. About 30-40 are used medicinally; each having its own specific healing properties. Some are convenient as inhalants; a few drops on a tissue for relief of catarrh, colds, etc. Fragrant burners and electronic diffusers are available for vapour-inhalation. Bring to boil 2 pints water; allow to stand 3-4 minutes; sprinkle on the surface 5-10 drops Eucalyptus oil and with towel over head, inhale steam, 5-10 minutes.

Examples: (a) equal parts dilute oils of Thyme and Hypericum (acute middle ear inflammation) 3-4 drops injected into ear 2-3 times daily. (b) 10 drops oil Marjoram in bath water for cramp. Eucalyptus is a useful antibacterial; Cinnamon (anti-inflammatory), Juniper (urinary antiseptic), Orange blossom (anti- depressant), Lavender (sedative).

Essential oils should never be used neat, except as prescribed by a suitably qualified practitioner. While aromatherapists do not prescribe internally, Dr Paul Belaiche, one of France’s leading experts on essential oils, advises oral medication at a maximum daily dosage of 12 drops according to the oil. He advises drops on the tongue, on activated charcoal, in capsule form using a suitable excipient or vegetable oil, or mixed with a little honey. Anal injection has proved successful, (8-10 drops in 10ml vegetable oil) or suppositories made from 200-300mg (8-10 drops) essential oil to 2 grams of base per suppository. Oils should never be allowed to touch the eyes.

Capsules of Garlic oil may be inserted into the rectum for worms or prostate disorder. OR: 10 drops oil mixed with 10ml vegetable oil and injected with the aid of a pipette. Dilute oil of Thyme is used as a massage-rub for chest infections. Oil of Cloves is not only an antiseptic but an analgesic to assuage moderate dental pain. Volatile oils reflexly stimulate the medulla through the olfactory nerve, thus promoting appetite and flow of saliva. All stimulate production of white blood cells and thereby support the immune system.

Oils not used: Basil, Bitter Almonds, Boldo, Calamus, Horseradish, Mugwort, Mustard, Pennyroyal, Rue, Sassafras, Savin, Tansy, Thuja, Wormseed.

Oils not used in pregnancy: Bay, Buchu, Chamomile, Clary Sage, Cinnamon, Clove, Fennel, Hyssop, Juniper, Marjoram, Myrrh, Peppermint, Rose, Rosemary, Sage, Thyme. All other oils – half the normal amount.

Tea: 2-3 drops, selected oil, on teabag makes 3 cups tea.

Inhalant: 10 drops on tissue, or same amount in hot water to inhale steam.

Bath water: add: 10-15 drops.

Compress: 10-15 drops in half a cup (75ml) milk or water. Soak suitable material and apply.

Massage: 6 drops in two teaspoons ‘carrier’ vegetable oil (Almond, Peanut, Olive, etc).

Fragrant oils replace hospital smell.

Eucalyptus, Blue Gum

Eucalyptus globulus var. globulus

FAMILY: Myrtaceae

SYNONYMS: Gum tree, southern blue gum, Tasmanian blue gum, fever tree, stringy bark.

GENERAL DESCRIPTION: A beautiful, tall, evergreen tree, up to 90 metres high. The young trees have bluish-green oval leaves while the mature trees develop long, narrow, yellowish leaves, creamy-white flowers and a smooth, pale grey bark often covered in a white powder.

DISTRIBUTION: Native to Tasmania and Australia. Mainly cultivated in Spain and Portugal, also Brazil, California, Russia and China. Very little of this oil now comes from its native countries.

OTHER SPECIES: There are over 700 different species of eucalyptus, of which at least 500 produce a type of essential oil. Many have been extracted simply for experimental purposes, and research is still being carried out with regard to the different constituents of each oil. In general, they can be divided into three categories. 1. The medicinal oils containing large amounts of cineol (or eucalyptol), such as the blue gum, but increasingly the blue malee (E. polybractea), the narrow-leaved peppermint (E. radiata var. australiana) and the gully gum (E. smithii). 2. The industrial oils containing mainly piperitone and phellandrene, such as the peppermint eucalyptus (E. piperita), grey peppermint (E. radiata var. phellandra) and increasingly the broad-leaved peppermint (E. dives var. Type). 3. The perfumery oils containing mainly citronellal, such as the lemon-scented eucalyptus (E. citriodora). See also Botanical Classification section.

HERBAL/FOLK TRADITION: A traditional household remedy in Australia, the leaves and oil are especially used for respiratory ailments such as bronchitis and croup, and the dried leaves are smoked like tobacco for asthma. It is also used for feverish conditions (malaria, typhoid, cholera, etc.) and skin problems like burns, ulcers and wounds. Aqueous extracts are used for aching joints, bacterial dysentery, ringworms, tuberculosis, etc. and employed for similar reasons in western and eastern medicine. The wood is also used for timber production in Spain.

ACTIONS: Analgesic, antineuralgic, antirheumatic, antiseptic, antispasmodic, antiviral, balsamic, cicatrisant, decongestant, deodorant, depurative, diuretic, expectorant, febrifuge, hypoglycaemic, parasiticide, prophylactic, rubefacient, stimulant, vermifuge, vulnerary.

EXTRACTION: Essential oil by steam distillation from the fresh or partially dried leaves and young twigs.

CHARACTERISTICS: A colourless mobile liquid (yellows on ageing), with a somewhat harsh camphoraceous odour and woody-sweet undertone. It blends well with thyme, rosemary, lavender, marjoram, pine, cedarwood and lemon. (The narrow-leaved eucalyptus (E. radiata var. australiana) is often used in preference to the blue gum in aromatherapy work, being rich in cineol but with a sweeter and less harsh odour.)

PRINCIPAL CONSTITUENTS: Cineol (70–85 per cent), pinene, limonene, cymene, phellandrene, terpinene, aromadendrene, among others.

SAFETY DATA: Externally non-toxic, non-irritant (in dilution), non-sensitizing. ‘When taken internally eucalyptus oil is toxic and as little as 3.5ml has been reported as fatal’..

AROMATHERAPY/HOME: USE

Skin Care: Burns, blisters, cuts, herpes, insect bites, insect repellent, lice, skin infections, wounds.

Circulation Muscles And Joints: Muscular aches and pains, poor circulation, rheumatoid arthritis, sprains, etc.

Respiratory System: Asthma, bronchitis, catarrh, coughs, sinusitis, throat infections.

Genito-Urinary System: Cystitis, leucorrhoea.

Immune System: Chickenpox, colds, epidemics, ’flu, measles.

Nervous System: Debility, headaches, neuralgia.

OTHER USES: The oil and cineol are largely employed in the preparation of liniments, inhalants, cough syrups, ointments, toothpaste and as pharmaceutical flavourings also used in veterinary practise and dentistry. Used as a fragrance component in soaps, detergents and toiletries – little used in perfumes. Used for the isolation of cineol and employed as a flavour ingredient in most major food categories.... eucalyptus, blue gum
