BAHAN AJAR Dyspepsia Dyspepsia covers pain, fullness, early satiety, bloating, and nausea. It can occur with gastric and duodenal ulceration and gastric cancer but most commonly it is of uncertain origin. Urgent endoscopic investigation is required if dyspepsia is accompanied by ‘alarm features’ (e.g. bleeding, dysphagia, recurrent vomiting, or weight loss). Urgent investigation should also be considered for patients over 55 years with unexplained dyspepsia that has not responded to treatment. Patients with dyspepsia should be advised about lifestyle changes (see Gastro-oesophageal reflux disease, below). Some medications may cause dyspepsia—these should be stopped, if possible. Antacids may provide some symptomatic relief. Histamine H -receptor antagonists heal gastric and duodenal ulcers by reducing gastric acid output as a result of histamine H -receptor blockade; they are also used to relieve symptoms of gastro-oesophageal reflux disease. H -receptor antagonists should not normally be used for Zollinger-Ellison syndrome because proton pump inhibitors are more effective. Maintenance treatment with low doses for the prevention of peptic ulcer disease has largely been replaced in Helicobacter pylori positive patients by eradication regimens H -receptor antagonists are used for the treatment of functional dyspepsia . Treatment of uninvestigated dyspepsia with H -receptor antagonists used regularly or on an intermittent basis, may be acceptable in younger patients but care is required in older people because of the possibility of gastric cancer in these patients. H -receptor antagonist therapy can promote healing of NSAID-associated ulcers (particularly duodenal) Treatment with a H -receptor antagonist has not been shown to be beneficial in haematemesis and melaena, but prophylactic use reduces the frequency of bleeding from gastroduodenal erosions in hepatic coma, and possibly in other conditions requiring intensive care. H - receptor antagonists also reduce the risk of acid aspiration in obstetric patients at delivery Antacids (usually containing aluminium or magnesium compounds) can often relieve symptoms in ulcer dyspepsia and in non-erosive gastro-oesophageal reflux; they are also sometimes used in functional (non-ulcer) dyspepsia but the evidence of benefit is uncertain. Antacids are best given when symptoms occur or are expected, usually between meals and at bedtime, 4 or more times daily; additional doses may be required up to once an hour. Conventional doses e.g. 10 mL 3 or 4 times daily of liquid magnesium– aluminium antacids promote ulcer healing, but less well than antisecretory drugs ; proof of a relationship between healing and neutralising capacity is lacking. Liquid preparations are more effective than tablet preparations. Aluminium- and magnesium-containing antacids (e.g. aluminium hydroxide, and magnesium carbonate, hydroxide and trisilicate), being relatively insoluble in water, are long-acting if retained in the stomach. They are suitable for most antacid purposes. Magnesiumcontaining antacids tend to be laxative whereas aluminium- containing antacids may be constipating; antacids containing both magnesium and aluminium may reduce these colonic side-effects. Aluminium accumulation does not appear to be a risk if renal function is normal The acid-neutralising capacity of preparations that contain more than one antacid may be the same as simpler preparations. Complexes such as hydrotalcite confer no special advantage. Sodium bicarbonate should no longer be prescribed alone for the relief of dyspepsia but it is present as an ingredient in many indigestion remedies. However, it retains a place in the management of urinary-tract disorders and acidosis . Sodium bicarbonate should be avoided in patients on salt-restricted diets. Simeticone (activated dimeticone) is added to an antacid as an antifoaming agent to relieve flatulence. These preparations may be useful for the relief of hiccup in palliative care. Alginates, added as protectants, may be useful in gastro-oesophageal reflux disease . The amount of additional ingredient or antacid in individual preparations varies widely, as does their sodium content, so that preparations may not be freely interchangeable. See also section 1.3 for drugs used in the treatment of peptic ulceration. Interactions Antacids should preferably not be taken at the same time as other drugs since they may impair absorption. Antacids may also damage enteric coatings designed to prevent dissolution in the stomach ALUMINIUM HYDROXIDE Indications dyspepsia; hyperphosphataemia , Cautions see notes above; renal impairment Contra-indications hypophosphataemia; neonates and infants Aluminium-only preparations Aluminium Hydroxide (Non-proprietary) Tablets, dried aluminium hydroxide 500 mg.

Net price 600 mL = £28.49 Adsorbents and bulk-forming drugs The priority in acute diarrhoea, as in gastro-enteritis, is the prevention or reversal of fluid and electrolyte depletion. This is particularly important in infants and in frail and elderly patients. For details of oral rehydration preparations, . Severe depletion of fluid and electrolytes requires immediate admission to hospital and urgent replacement. Antimotility drugs relieve symptoms of acute diarrhoea. They are used in the management of uncomplicated acute diarrhoea in adults; fluid and electrolyte replacement may be necessary in case of dehydration. However, antimotility drugs are not recommended for acute diarrhoea in young children. Antispasmodics are occasionally of value in treating abdominal cramp associated with diarrhoea but they should not be used for primary treatment. Antispasmodics and antiemetics should be avoided in young children with gastro-enteritis because they are rarely effective and have troublesome side-effects. Adsorbents such as kaolin are not recommended for acute diarrhoeas. Bulk-forming drugs, such as ispaghula, methylcellulose, and sterculia (section 1.6.1) are useful in controlling diarrhoea associated with diverticular disease. KAOLIN, LIGHTU Indications diarrhoea but see notes above Cautions interactions: Appendix 1 (kaolin) Kaolin Mixture, BPU (Kaolin Oral Suspension) Oral suspension, light kaolin or light kaolin (natural) 20%, light magnesium carbonate 5%, sodium bicarbonate 5% in a suitable vehicle with a peppermint flavour. Dose 10–20 mL every 4 hours Laxatives Before prescribing laxatives it is important to be sure that the patient is constipated and that the constipation is not secondary to an underlying undiagnosed complaint. It is also important for those who complain of constipation to understand that bowel habit can vary considerably in frequency without doing harm. Some people tend to consider themselves constipated if they do not have a bowel movement each day. A useful definition of constipation is the passage of hard stools less frequently than the patient’s own normal pattern and this can be explained to the patient. Misconceptions about bowel habits have led to excessive laxative use. Abuse may lead to hypokalaemia. Thus, laxatives should generally be avoided except where straining will exacerbate a condition (such as angina) or increase the risk of rectal bleeding as in haemorrhoids. Laxatives are also of value in druginduced constipation, for the expulsion of parasites after anthelmintic treatment, and to clear the alimentary tract before surgery and radiological procedures. Prolonged treatment of constipation is sometimes necessary. Children Laxatives should be prescribed by a healthcare professional experienced in the management of constipation in children. Delays of greater than 3 days between stools may increase the likelihood of pain on passing hard stools leading to anal fissure, anal spasm and eventually to a learned response to avoid defaecation. If increased fluid and fibre intake is insufficient, an osmotic laxative containing macrogols or lactulose can be used. If there is evidence of minor faecal retention, the addition of a stimulant laxative may overcome withholding but may lead to colic or, in the presence of faecal impaction in the rectum, an increase of faecal overflow. In children with faecal impaction, an oral preparation containing macrogols is used to clear faecal mass and to establish and maintain soft well-formed stools. Rectal administration of laxatives may be effective but this route is frequently distressing for the child and may lead to persistent withholding. If the impacted mass is not expelled following treatment with macrogols, referral to hospital may be necessary. Enemas may be administered under heavy sedation in hospital or alternatively, a bowel cleansing solution may be tried. In severe cases or where the child is afraid, a manual evacuation under anaesthetic may be appropriate. Long-term regular use of laxatives is essential to maintain well-formed stools and prevent recurrence of faecal impaction; intermittent use may provoke relapses. For children with chronic constipation, it may be necessary to exceed the licensed doses of some laxatives. Parents and carers of children should be advised to adjust the dose of laxative in order to establish a regular pattern of bowel movements in which stools are soft, well-formed, and passed without discomfort. Pregnancy If dietary and lifestyle changes fail to control constipation in pregnancy, moderate doses of poorly absorbed laxatives may be used. A bulk-forming laxative should be tried first. An osmotic laxative, such as lactulose, can also be used. Bisacodyl or senna may be suitable, if a stimulant effect is necessary. The laxatives that follow have been divided into 5 main groups. This simple classification disguises the fact that some laxatives have a complex action. Bulk-forming laxatives Bulk-forming laxatives relieve constipation by increasing faecal mass which stimulates peristalsis; patients should be advised that the full effect may take some days to develop. Bulk-forming laxatives are of particular value in those with small hard stools, but should not be required unless fibre cannot be increased in the diet. A balanced diet, including adequate fluid intake and fibre is of value in preventing constipation. Bulk-forming laxatives are useful in the management of patients with colostomy, ileostomy, haemorrhoids, anal fissure, chronic diarrhoea associated with diverticular disease, irritable bowel syndrome, and as adjuncts in ulcerative colitis . Adequate fluid intake must be maintained to avoid intestinal obstruction. Unprocessed wheat bran, taken with food or fruit juice, is a most effective bulk-forming preparation. Finely ground bran, though more palatable, has poorer waterretaining properties, but can be taken as bran bread or biscuits in appropriately increased quantities. Oat bran is alsoused. Methylcellulose, ispaghula, and sterculia are useful in patients who cannot tolerate bran. Methylcellulose also acts as a faecal softener. BISACODYL Contra-indications see notes above, acute surgical abdominal conditions, acute inflammatory bowel disease, severe dehydration Dose . Constipation, by mouth, 5–10 mg at night; CHILD (but see section 1.6) 4–10 years (on medical advice only) 5 mg at night, over 10 years, adult dose By rectum in suppositories, 10 mg in the morning; CHILD (but see section 1.6) under 10 years (on medical advice only) 5 mg, over 10 years, adult dose . Before radiological procedures and surgery, by mouth, 10–20 mg the night before procedure and by rectum in suppositories, 10 mg the following morning; CHILD 4–10 years by mouth, 5 mg the night before procedure and by rectum in suppositories, 5 mg the following morning; over 10 years, adult dose Note tablets act in 10–12 hours; suppositories act in 20–60 minutes The brand names Dulcolax Liquid and Dulcolax Perles are used for sodium picosulfate preparations The selective beta agonists (selective beta –adrenoceptor agonists, selective beta stimulants) such as salbutamol or terbutaline are the safest and most effective shortacting beta agonists for asthma. Less selective beta agonists such as orciprenaline should be avoided whenever possible. Adrenaline (epinephrine) (which has both alpha- and beta-adrenoceptor agonist properties) is used in the emergency management of allergic and anaphylactic reactions and in the management of croup . Selective beta2 agonists Selective beta agonists produce bronchodilation. A short-acting beta agonist is used for immediate relief of asthma symptoms while a long-acting beta agonist is added to an inhaled corticosteroid in patients requiring prophylactic treatment. Short-acting beta agonists Mild to moderate symptoms of asthma respond rapidly to the inhalation of a selective short-acting beta agonist such as salbutamol or terbutaline. If beta agonist inhalation is needed more often than once daily, prophylactic treatment should be considered, using a stepped approach as outlined in the Management of Chronic Asthma table,. Regular treatment with an inhaled short-acting beta agonist is less effective than ‘as required’ inhalation and is not appropriate prophylactic treatment. A short-acting beta agonist inhaled immediately before exertion reduces exercise-induced asthma; however, frequent exercise-induced asthma probably reflects poor overall control and calls for reassessment of asthma treatment. Long-acting beta agonists Formoterol (eformoterol) and salmeterol are longer-acting beta agonists which are administered by inhalation. Added to regular inhaled corticosteroid treatment, they have a role in the long-term control of chronic asthma and they can be useful in nocturnal asthma. Salmeterol should not be used for the relief of an asthma attack; it has a slower onset of action than salbutamol or terbutaline. Formoterol is licensed for short-term symptom relief and for the prevention of exercise-induced bronchospasm; its speed of onset of action is similar to that of salbutamol. EPHEDRINE HYDROCHLORIDEU Indications reversible airways obstruction, Cautions hyperthyroidism, diabetes mellitus, ischaemic heart disease, hypertension, renal impairment, elderly; prostatic hypertrophy (risk of acute retention); interaction with MAOIs a disadvantage; Side-effects tachycardia, anxiety, restlessness, insomnia common; also tremor, arrhythmias, dry mouth, cold extremities Dose 15–60 mg 3 times daily; CHILD up to 1 year 7.5 mg 3 times daily, 1–5 years 15 mg 3 times daily, 6–12 years 30 mg 3 times daily Theophylline Theophylline is a bronchodilator used for asthma and stable chronic obstructive pulmonary disease; it is not generally effective in exacerbations of chronic obstructivepulmonary disease. It may have an additive effect when used in conjunction with small doses of beta agonists; the combination may increase the risk of side-effects, including hypokalaemia Theophylline is metabolised in the liver; there is considerable variation in plasmatheophylline concentration particularly in smokers, in patients with hepatic impairment or heart failure, or if certain drugs are taken concurrently. The plasma-theophylline concentration is increased in heart failure, cirrhosis, viral infections, in the elderly, and by drugs that inhibit its metabolism. The plasma-theophylline concentration is decreased in smokers and in chronic alcoholism and by drugs that induce liver metabolism. For other interactions of theophylline Differences in the half-life of theophylline are importantbecause its toxic dose is close to the therapeutic dose; particular care is required when introducing or withdrawing drugs that interact with theophylline. In most individuals a plasma-theophylline concentration of between 10–20 mg/litre is required for satisfactory bronchodilation, although a plasma-theophylline concentration of 10 mg/litre (or less) may be effective. Adverse effects can occur within the range 10–20 mg/ litre and both the frequency and severity increase at concentrations above 20 mg/litre. Theophylline is given by injection as aminophylline, a mixture of theophylline with ethylenediamine, which is 20 times more soluble than theophylline alone. Aminophylline injection is needed rarely for severe attacks of asthma. It must be given by very slow intravenous injection (over at least 20 minutes); it is too irritant for intramuscular use. Measurement of plasma theophylline concentration may be helpful, and is essential if aminophylline is to be given to patients who have been taking theophylline, because serious side-effects such as convulsions and arrhythmias can occasionally precede other symptoms of toxicity. THEOPHYLLINE Indications reversible airways obstruction, acute severe asthma; see also Management of Chronic and Acute Asthma Cautions cardiac disease, hypertension, hyperthyroidism; peptic ulcer; epilepsy; elderly; fever; CSM advice on hypokalaemia risk, ; avoid in acute porphyria ; monitor plasma-theophylline concentration (see notes above); hepatic impairment ; pregnancy ; Side-effects tachycardia, palpitation, nausea and other gastro-intestinal disturbances, headache, CNS stimulation, insomnia, arrhythmias, and convulsions especially if given rapidly by intravenous injection; overdosage: see Emergency Treatment of Poisoning, Note Plasma-theophylline concentration for optimum response 10–20 mg/litre (55–110 micromol/litre); 4–6 hours after a dose and at least 5 days after starting treatment; narrow margin between therapeutic and toxic dose, see also notes above Modified release Note The rate of absorption from modified-release preparations can vary between brands. The Council of the Royal Pharmaceutical Society of Great Britain advises pharmacists that if a general practitioner prescribes a modified-release oral theophylline preparation without specifying a brand name, the pharmacist should contact the prescriber and agree the brand to be dispensed.

They reduce rhinorrhoea and sneezing but are usually less effective for nasal congestion. Antihistamines are used topically in the eye (section 11.4.2), in the nose , and on the skin Oral antihistamines are also of some value in preventing urticaria and are used to treat urticarial rashes, pruritus, and insect bites and stings; they are also used in drug allergies. Injections of chlorphenamine (chlorpheniramine) or promethazine are used as an adjunct to adrenaline (epinephrine) in the emergency treatment of anaphylaxis and angioedema . For the use of antihistamines (including cinnarizine, cyclizine, and promethazine teoclate) in nausea and vomiting, see section 4.6. Buclizine is included as an anti-emetic in a preparation for migraine . For reference to the use of antihistamines for occasional insomnia, All older antihistamines cause sedation but alimemazine (trimeprazine) and promethazine may be more sedating whereas chlorphenamine and cyclizine may be less so. This sedating activity is sometimes used to manage the pruritus associated with some allergies. There is little evidence that any one of the older, ‘sedating’ antihistamines is superior to another and patients vary widely in their response. Non-sedating antihistamines such as cetirizine, desloratadine (an active metabolite of loratadine), fexofenadine (an active metabolite of terfenadine), levocetirizine (an isomer of cetirizine), loratadine, and mizolastine cause less sedation and psychomotor impairment than the older antihistamines because they penetrate the blood brain barrier only to a slight extent. Cautions and contra-indications Sedating antihistamines have significant antimuscarinic activity and they should therefore be used with caution in prostatic hypertrophy, urinary retention, susceptibility to angle-closure glaucoma, and pyloroduodenal obstruction. Antihistamines should be used with caution in hepatic disease Caution may be required in epilepsy. Children and the elderly are more susceptible to sideeffects. Many antihistamines should be avoided in acute porphyria but some are thought to be safe, see section Side-effects Drowsiness is a significant side-effect with most of the older antihistamines although paradoxical stimulation may occur rarely, especially with high doses or in children and the elderly. Drowsiness may diminish after a few days of treatment and is considerably less of a problem with the newer antihistamines . Side-effects that are more common with the older antihistamines include headache, psychomotor impairment, and antimuscarinic effects such as urinary retention, dry mouth, blurred vision, and gastro-intestinal disturbances. Other rare side-effects of antihistamines include hypotension, palpitation, arrhythmias, extrapyramidal effects, dizziness, confusion, depression, sleep disturbances, tremor, convulsions, hypersensitivity reactions (including bronchospasm, angioedema, and anaphylaxis, rashes, and photosensitivity reactions), blood disorders, liver dysfunction, and angle-closure glaucoma. Non-sedating antihistamines Driving Although drowsiness is rare, nevertheless patients should be advised that it can occur and may affect performance of skilled tasks (e.g. driving); excess alcohol should be avoided. CETIRIZINE HYDROCHLORIDE Indications symptomatic relief of allergy such as hay fever, chronic idiopahtic urticaria Cautions see notes above; also renal impairment Contra-indications see notes above; also pregnancy Dose ADULT and CHILD over 6 years, 10 mg once daily or5mg twice daily; CHILD 1–2 years see BNF for Children, 2–6 years, hay fever, 5 mg once daily or 2.5 mg twice daily Cetirizine (Non-proprietary) Tablets, cetirizine hydrochloride 10 mg, net price 30tab pack = 97p.

Counselling, driving Cough suppressants Cough may be a symptom of an underlying disorder, such as asthma , gastro-oesophageal reflux disease, or rhinitis , which should be addressed before prescribing cough suppressants. Cough may be a side-effect of another drug, such as an ACE inhibitor , or it can be associated with smoking or environmental pollutants. Cough can also have a significant habit component. When there is no identifiable cause, cough suppressants may be useful, for example if sleep is disturbed. They may cause sputum retention and this may be harmful in patients with chronic bronchitis and bronchiectasis. Non-opioid analgesics Aspirin is indicated for headache, transient musculoskeletalpain, dysmenorrhoea and pyrexia. In inflammatory conditions, most physicians prefer anti-inflammatory treatment with another NSAID which may be better tolerated and more convenient for the patient. Aspirin is used increasingly for its antiplatelet properties . Aspirin tablets or dispersible aspirin tablets are adequate for most purposes as they act rapidly. Gastric irritation may be a problem; it is minimised by taking the dose after food. Enteric-coated preparations are available, but have a slow onset of action and are therefore unsuitable for single-dose analgesic use(though their prolonged action may be useful for nightpain). Aspirin interacts significantly with a number of other drugs and its interaction with warfarin is a special hazard, see interactions: (aspirin). Paracetamol is similar in efficacy to aspirin, but has no demonstrable anti-inflammatory activity; it is less irritant to the stomach and for that reason is now generally preferred to aspirin, particularly in the elderly. Overdosage with paracetamol is particularly dangerous as it may cause hepatic damage which is sometimes not apparent for 4 to 6 days (see Emergency Treatment of Poisoning, p. 29). Nefopam may have a place in the relief of persistent pain unresponsive to other non-opioid analgesics. It causes little or no respiratory depression, but sympathomimetic and antimuscarinic side-effects may be troublesome. Non-steroidal anti-inflammatory analgesics (NSAIDs, section 10.1.1) are particularly useful for the treatment of patients with chronic disease accompanied by pain and inflammation. Some of them are also used in the short-term treatment of mild to moderate pain including transient musculoskeletal pain but paracetamol is now often preferred, particularly in the elderly . They are also suitable for the relief of pain in dysmenorrhoea and to treat pain caused by secondary bone tumours, many of which produce lysis of bone and release prostaglandins Compound analgesic preparations Compound analgesic preparations that contain a simple analgesic (such as aspirin or paracetamol) with an opioid component reduce the scope for effective titration of the individual components in the management of pain of varying intensity. Compound analgesic preparations containing paracetamol or aspirin with a low dose of an opioid analgesic (e.g. 8 mg of codeine phosphate per compound tablet) are commonly used, but the advantages have not been substantiated. The low dose of the opioid may be enough to cause opioid side-effects (in particular, constipation) and can complicate the treatment of overdosage yet may not provide significant additional relief of pain. A full dose of the opioid component (e.g. 60 mg codeine phosphate) in compound analgesic preparations effectively augments the analgesic activity but is associated with the full range of opioid side-effects (including nausea, vomiting, severe constipation, drowsiness, respiratory depression, and risk of dependence on long-term administration). For details of the side-effects of opioid analgesics, (important: the elderly are particularly susceptible to opioid side-effects and should receive lower doses). In general, when assessing pain, it is necessary to weigh up carefully whether there is a need for a non-opioid and an opioid analgesic to be taken simultaneously. For information on the use of combination analgesic preparations in dental and orofacial pain, Caffeine is a weak stimulant that is often included, insmall doses, in analgesic preparations. It is claimed that the addition of caffeine may enhance the analgesic effect, but the alerting effect, mild habit-forming effect and possible provocation of headache may not always be desirable. Moreover, in excessive dosage or on withdrawal caffeine may itself induce headache. Co-proxamol tablets (dextropropoxyphene in combination with paracetamol) are no longer licensed because of safety concerns, particularly toxicity in overdose. Coproxamol tablets [unlicensed] may still be prescribed for patients who find it difficult to change, because, for example, alternatives are not effective or suitable.
