Dose: 0.25-1.5ingdaily. (Anquil).
benserazide An enzyme inhibitor used with Ivvodopa in parkinsonism. It inhibits the breakdown of levodopa to dopamine, enabling large amounts to reach the brain, and so permits a reduction in dose and a smoother response. Some of the side-effects of levodopa, such as nausea and vomiting, may also be reduced, although the incidence of involuntary movements may increase.
Dose: 12.5 mg with 50 ing of levodopa. (N-ladopan). See page 160 and Table 26.

Dose: I mg initially, slowly increased to 5-15 mg daily according to need. Side-effects include mouth dryness, dizziness and blurred vision. Care is necessary with high doses as some psychiatric disturbances may occur anti    withdrawal of the
drug, but abrupt discontinuance of treatment should be avoided. Benzhexol should be used with care in cases of glaucoma, hepatic and cardiac disease or urinary disturbances. (Arcane; Broflex). See
page 160 and Table 26.

(5- 1 0(y.); suppositories 200 mg.
benzodiazepines A widely used group of drugs with a powerful action on the central nervous system. ‘rhey appear to have a selective action on certain seroionin receptors. The type of action varies within the group, and they may be used as sedatives, hypnotics, anxiolytics, anticonvul&-ints or muscle relaxants. As hypnotics they have virtually replaced the barbiturates, as they have a wide margin of safety and are less dangerous in overdose. Prolonged use should he avoided as dependence remains a possibility. The withdrawal of treatment with benzodiazepines should be gradual, as otherwise confusion, convulsions and toxic psychoses may occur. Nitrazepam has a relatively long action as a hypnotic, whereas flunitrazepam has a shorter action. Diazepam is the preferred drug for controlling the spasms of tetanus. Hypnotic pnotic benzodiazepines include flunitrazepam, flurazepam, loprazolam, lormetazepam, nitrazeparnand temazepam.Those used as anxiolytics are alprazolam, bromazepam, chlordiazepoxide, clobazam, clorampate, diazepam, ketazolam, lorazepam, medazepam and oxazepam. Most of these diazepines are referred to briefly under the above names. See page 117 and,rable 5.

benzthiazide A thiazide diuretic present with trianiterene in Dytide.

benztropine An anticholinergic drug, used to relieve the rigidity, tremor and salivation of Parkinson’s disease. It also has some sedative action, and in some cases may be preferred to benzhexol. Like benzhexol, it is sometimes useful in the control of drug-induced extrapyramidal svillptoms.
Dose: 0.5-6 mg daily. In severe conditions, it may be given by injection of
1-2 mg, repeated according to response. The side-effects are those of the anticholinergic drugs generally. (Cogentin). See page 160 and Table 26.
benzydamine A mild analgesic used as a mouthwash (0.15%) for painful conditions of the mouth and throat, and as a cream (31YO for musculoskeletal pain.

benzyl penicillin See penicillin.
beta-Mockers in cardiac failure, heart block and bradycardia. See pages 114 & 148, and Tables 4 & 21.
betahistine A vasodilator with some of the properties of histamine. Used to reduce the vertigo of N!6ni&e’s disease. Should be used with care in asthmatics and in peptic ulcer.
Dose: 16-48 ing daily. (Sere).
betarnethasone A corticosteroid characterized by its low dose, increased anti-inflammatory action, and reduced side-effects. It has virtually no salt-retaining properties, and causes little increase in the urinary excretion of potassium. It is indicated in all inflammatory, allergic and other conditions requiring corticosteroid therapy - with the exception of Addison’s disease and after adrenalectomy when a salt-retaining steroid is required.
Dose: 0.5-5 mg daily; in cerebral oedema, 5 20 mg by Lin. or i.v. injection. In asthmatic states, oral aerosol inhalation of M)pg (eight puffs) daily; for inflaninialory conditions of the eye, car and nose, a 0, PN, solution is used locally. (Belnesol).
beractant A pulmonary surfactant used in the respiratory distress syndrome of premature infants, by endotracheal tubing within 8 hours of birth. Monitor heart rate and arterial oxygenation. (Survanta). See also colfesceril, poractant and pumactant.
beta-adrenoceptor blocking agents Adrenaline and related catecholamines are released into the circulation during exercise and stress, and stimulate cardiac output by acting oil the beta-adrenoceptor sites in the heart. When such stimulation is excessive the increased oxygen demand of the heart may cause myocardial insufficiency and angina. Drugs such as propranolol block these receptor sites and so indirectly reduce cardiac stimulation, and are of value in the control of angina, cardiac arrhythmias and hypertension. Some blocking agents also act on other receptor sites and may cause bronchospasm by releasing histamine. Newer drugs, represented by acebutolol and nicroprolol, are more cardioselective, and others such as sotalol are of more value in hypertension. Sonic of these blocking agents,such as atenolol, are less likely to reach the central nervous system and so may cause fewer sleep disturbances. By their nature and depressant action on the myocardium, care is necessary when giving
betaxolol A beta-adrenoceptor blocking agent of the propranolol type, with similar properties and side-effects, but with a more cardioselective action. It is used mainly in the treatment of hypertension. Dose: 20 mg once daily. Betaxolol is also used as eye drops (0.5%) in ocular hypertension and glaucoma. (Betoptic-, Kerlone). See page 148 and Table 21.
bethanechol A parasympathominictic agent used in reflex oesophagitis, paralytic ileus and postoperative urinary retention. Dose: 30-120 mg daily before food. Side-effects are nausea, bradycardia and colic. Care is necessary in asthma and cardiovasculardiscase. (Myotoninc).
bethanidine A blocking agent that has an anfihypcttcnsivc action by inhibiting the release of noradrenaline from post-ganglionic adrenergic nerve endings. It is useful in resistant hypertension, and when other agents are not well tolerated, and is usually given in association with a thiazide diuretic or a beta-Mocker.
Dose: 20-200 ing daily. Postural hypotension, nasal congestion and diarrhoea are side-effects. (Bendogen).
