NICE decisions

▶ Pirfenidone for treating idiopathic pulmonary fibrosis

(February 2018) NICE TA504

Pirfenidone (Esbriet ®) is recommended as an option for

treating idiopathic pulmonary fibrosis in adults only if:

. the patient has a forced vital capacity (FVC) between

50% and 80% predicted, and

. the manufacturer provides pirfenidone with the discount

agreed in the patient access scheme, and

. treatment is stopped if there is evidence of disease

progression (an absolute decline of 10% or more in

predicted FVC within any 12-month period).

Patients whose treatment was started within the NHS

before this guidance was published should have the option

to continue treatment, without change to their funding

arrangements, until they and their NHS clinician consider

it appropriate to stop.

Scottish Medicines Consortium (SMC) decisions

SMC No. 835/13

The Scottish Medicines Consortium has advised (August

2013) that pirfenidone (Esbriet ®) is accepted for restricted

use within NHS Scotland for the treatment of mild to

moderate idiopathic pulmonary fibrosis. Pirfenidone is

restricted for use in patients with a predicted forced vital

capacity less than or equal to 80%, and only whilst

Respiratory stimulants

Overview

Respiratory stimulants (analeptic drugs) have a limited place

in the treatment of ventilatory failure in patients with

chronic obstructive pulmonary disease. They are effective

only when given by intravenous injection or infusion and

have a short duration of action. Their use has largely been

replaced by ventilatory support including nasal intermittent

positive pressure ventilation. However, occasionally when

ventilatory support is contra-indicated and in patients with

hypercapnic respiratory failure who are becoming drowsy or

comatose, respiratory stimulants in the short term may

arouse patients sufficiently to co-operate and clear their

secretions.

Respiratory stimulants can also be harmful in respiratory

failure since they stimulate non-respiratory as well as

respiratory muscles. They should only be given under expert

supervision in hospital and must be combined with active

physiotherapy. There is at present no oral respiratory

stimulant available for long-term use in chronic respiratory

failure.

1 Dementia

Dementia 14-Sep-2018

Description of condition

Dementia is a progressive clinical syndrome characterised by

a range of cognitive and behavioural symptoms that can

include memory loss, problems with reasoning and

communication, a change in personality, and a reduced

ability to carry out daily activities such as washing or

dressing. Alzheimer’s disease is the most common type of

dementia; other common types of dementia include vascular

dementia (due to cerebrovascular disease), dementia with

Lewy bodies, mixed dementia, and frontotemporal dementia.

Aims of treatment

The aim of treatment is to promote independence, maintain

function, and manage symptoms of dementia.

Non-drug treatment

g Patients with all types of mild-to-moderate dementia

presenting with cognitive symptoms should be given the

opportunity to participate in a structured group cognitive

stimulation programme. Group reminiscence therapy (use of

life stories to improve psychological well-being), and

cognitive rehabilitation or occupational therapy to support

daily functional ability, should also be considered. h

Management of cognitive symptoms

g Some commonly prescribed drugs are associated with

increased antimuscarinic (anticholinergic) burden, and

therefore cognitive impairment; their use should be

minimised. hDrugs with antimuscarinic effects include

some antidepressants (e.g. amitriptyline hydrochloride

p. 372, paroxetine p. 366), antihistamines (e.g.

chlorphenamine maleate p. 283, promethazine

hydrochloride p. 286), antipsychotics (e.g. olanzapine p. 398,

quetiapine p. 401), and urinary antispasmodics (e.g.

solifenacin succinate p. 779, tolterodine tartrate p. 780).

Alzheimer’s disease

g In newly diagnosed patients, drug treatment should

only be initiated under the advice of a specialist clinician

experienced in the management of Alzheimer’s disease.

In patients with mild-to-moderate Alzheimer’s disease,

monotherapy with donepezil hydrochloride p. 301,

galantamine p. 302, or rivastigmine p. 303

(acetylcholinesterase inhibitors) are first-line treatment

options. If acetylcholinesterase inhibitors are not tolerated

or contra-indicated, memantine hydrochloride p. 304 is a

suitable alternative in patients with moderate Alzheimer’s

disease. Memantine hydrochloride is the drug of choice in

patients with severe Alzheimer’s disease.

In patients already receiving an acetylcholinesterase

inhibitor to treat Alzheimer’s disease, the addition of

memantine hydrochloride should be considered if they

develop moderate or severe disease; in this case, memantine

hydrochloride can be initiated in primary care without advice

from a specialist clinician. h

In patients with moderate Alzheimer’s disease,

discontinuing acetylcholinesterase inhibitor treatment can

cause a substantial worsening in cognitive function;g

treatment discontinuation should not be based on disease

severity alone. h

Non-Alzheimer’s dementia

g Donepezil hydrochloride [unlicensed indication] or

rivastigmine [unlicensed indication] should be given to

patients with mild-to-moderate dementia with Lewy bodies;

galantamine [unlicensed indication] can be considered only

if treatment with both donepezil hydrochloride or

rivastigmine is not tolerated. Donepezil hydrochloride

[unlicensed indication] or rivastigmine [unlicensed

indication] can also be considered in patients with severe

dementia with Lewy bodies. Memantine hydrochloride

[unlicensed indication] can be considered as an alternative in

patients with dementia with Lewy bodies in whom

acetylcholinesterase inhibitors are contra-indicated or not

tolerated.

Acetylcholinesterase inhibitors [unlicensed indication] or

memantine hydrochloride [unlicensed indication] should

only be considered in patients with vascular dementia if they

have suspected co-morbid Alzheimer’s disease, Parkinson’s

disease dementia, or dementia with Lewy bodies. h

300 Nervous system BNF 78

Nervous system

g Acetylcholinesterase inhibitors and memantine

hydrochloride are not recommended in patients with

frontotemporal dementia or cognitive impairment caused by

multiple sclerosis. h

For management of Parkinson’s disease dementia see

Parkinson’s disease p. 409.

Management of non-cognitive symptoms

Agitation, aggression, distress and psychosis

g Patients with dementia should be offered psychosocial

and environmental interventions such as counselling and

management of pain and delirium to reduce distress.

Antipsychotic drugs should only be offered to patients

with dementia if they are either at risk of harming

themselves or others, or experiencing agitation,

hallucinations or delusions that are causing them severe

distress. hThe CHM/MHRA has reported (2009) an

increased risk of stroke and a small increased risk of death

when antipsychotic drugs are used in elderly patients with

dementia. The balance of risks and benefits should be

carefully assessed, including any previous history of stroke

or transient ischaemic attack and any risk factors for

cerebrovascular disease such as hypertension, diabetes,

smoking, and atrial fibrillation.

g Antipsychotic drugs should be used at the lowest

effective dose and for the shortest time possible, with a

regular review at least every 6 weeks. h

In patients who have dementia with Lewy bodies or

Parkinson’s disease dementia, antipsychotic drugs can

worsen the motor features of the condition, and in some

cases cause severe antipsychotic sensitivity reactions. See

also management of psychotic symptoms in Parkinson’s

disease p. 409.

Depression and anxiety

g Psychological treatments (e.g. cognitive behavioural

therapy (CBT), multisensory stimulation, relaxation, or

animal-assisted therapies) should be considered for patients

with mild-to-moderate dementia who have mild to moderate

depression or anxiety; antidepressants should be reserved

for pre-existing severe mental health problems. h

Sleep disturbances

g Patients should be offered non-drug treatment

approaches to manage sleep problems and insomnia,

including sleep hygiene education, exposure to daylight, and

increasing exercise and activity. h

l NATIONAL FUNDING/ACCESS DECISIONS

NICE decisions

▶ Donepezil, galantamine, rivastigmine, and memantine for the

treatment of Alzheimer’s disease (updated June 2018)

NICE TA217

The three acetylcholinesterase (AChE) inhibitors

donepezil, galantamine, and rivastigmine as

monotherapies are recommended as options for managing

mild to moderate Alzheimer’s disease under all of the

conditions specified below and in recommendation 1.5.5 of

the NICE guideline on dementia.

If prescribing an AChE inhibitor (donepezil,

galantamine, or rivastigmine), treatment should normally

be started with the drug with the lowest acquisition cost

(taking into account required daily dose and the price per

dose once shared care has started). However, an

alternative AChE inhibitor could be prescribed if it is

considered appropriate when taking into account adverse

event profile, expectations about adherence, medical

comorbidity, possibility of drug interactions and dosing

profiles.

Healthcare professionals should not rely solely on

assessment scales to determine the severity of Alzheimer’s

disease when the patient has learning or other disabilities,

or other communication difficulties.

l NATIONAL FUNDING/ACCESS DECISIONS

Scottish Medicines Consortium (SMC) decisions

The Scottish Medicines Consortium has advised (December

2016) that ivacaftor (Kalydeco ®) is not recommended for

use within NHS Scotland for the treatment of patients with

cystic fibrosis aged 18 years and above who have an R117H

mutation in the cystic fibrosis transmembrane

conductance regulator (CFTR) gene, as insufficient clinical

and economic evidence was submitted.

All Wales Medicines Strategy Group (AWMSG) decisions

The All Wales Medicines Strategy Group has advised

(October 2017) that ivacaftor (Kalydeco ®) is recommended

for restricted use within NHS Wales for the treatment of

adults with cystic fibrosis (CF) who have an R117H

mutation in the CF transmembrane conductance regulator

(CFTR) gene. This recommendation will apply only when

4 Cough and congestion

Aromatic inhalations, cough

preparations and systemic nasal

decongestants

Aromatic inhalations in adults

Inhalations containing volatile substances such as

eucalyptus oil are traditionally used and although the vapour

may contain little of the additive it encourages deliberate

inspiration of warm moist air which is often comforting in

bronchitis; boiling water should not be used owing to the

risk of scalding. In practice, inhalations are also used for the

relief of nasal obstruction in acute rhinitis or sinusitis.

Cough preparations in adults

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.

There is some evidence to suggest that codeine phosphate

p. 454 provides no benefit for symptoms of acute cough.

Codeine phosphate is also constipating and can cause

dependence; dextromethorphan and pholcodine below

have fewer side-effects.

Sedating antihistamines are used as the cough

suppressant component of many compound cough

preparations on sale to the public; all tend to cause

drowsiness which may reflect their main mode of action.

Palliative care

Diamorphine hydrochloride p. 456 and methadone

hydrochloride p. 502 have been used to control distressing

cough in terminal lung cancer although morphine p. 463 is

now preferred. In other circumstances they are contraindicated because they induce sputum retention and

ventilatory failure as well as causing opioid dependence.

Methadone hydrochloride linctus should be avoided because

it has a long duration of action and tends to accumulate.

Demulcent and expectorant cough preparations

Demulcent cough preparations contain soothing

substances such as syrup or glycerol and some patients

believe that such preparations relieve a dry irritating cough.

Preparations such as simple linctus have the advantage of

being harmless and inexpensive; paediatric simple linctus

is particularly useful in children.

Expectorants are claimed to promote expulsion of

bronchial secretions, but there is no evidence that any drug

can specifically facilitate expectoration.

g An over-the-counter cough medicine containing the

expectorant guaifenesin may be used for acute cough; there

is some evidence to suggest it may reduce symptoms. h

Compound preparations are on sale to the public for the

treatment of cough and colds but should not be used in

children under 6 years; the rationale for some is dubious.

Care should be taken to give the correct dose and to not use

more than one preparation at a time.

Nasal decongestants, systemic

Nasal decongestants for administration by mouth may not

be as effective as preparations for local application but they

do not give rise to rebound nasal congestion on withdrawal.

Pseudoephedrine hydrochloride p. 1202 is available over the

counter; it has few sympathomimetic effects.

Aromatic inhalations in children

The use of strong aromatic decongestants (applied as rubs or

to pillows) is not advised for infants under the age of

3 months. Carers of young infants in whom nasal obstruction

with mucus is a problem can readily be taught appropriate

techniques of suction aspiration but sodium chloride 0.9%

p. 1040 given as nasal drops is preferred; administration

before feeds may ease feeding difficulties caused by nasal

congestion.

Cough preparations in children

The use of over-the-counter cough suppressants containing

codeine phosphate should be avoided in children under

12 years and in children of any age known to be CYP2D6

ultra-rapid metabolisers. Cough suppressants containing

similar opioid analgesics such as dextromethorphan and

pholcodine are not generally recommended in children and

should be avoided in children under 6 years;

dextromethorphan should be avoided in children under

12 years.

MHRA/CHM advice (March 2008 and February 2009)

Children under 6 years should not be given over-the-counter

cough and cold medicines containing the following

ingredients:

. brompheniramine, chlorphenamine maleate p. 283,

diphenhydramine, doxylamine, promethazine, or

triprolidine (antihistamines);

. dextromethorphan or pholcodine (cough suppressants);

. guaifenesin or ipecacuanha (expectorants);

. Phenylephrine hydrochloride p. 189, pseudoephedrine

hydrochloride, ephedrine hydrochloride p. 1202,

oxymetazoline, or xylometazoline hydrochloride p. 1203

(decongestants).

Over-the-counter cough and cold medicines can be

considered for children aged 6–12 years after basic principles

of best care have been tried, but treatment should be

restricted to five days or less. Children should not be given

more than 1 cough or cold preparation at a time because

different brands may contain the same active ingredient;

care should be taken to give the correct dose.
