• Pharmacotherapy for Smoking cessation

• Maintenance/ Follow-ups

Tobacco use can kill in so may ways that it is a risk factor for six of the eight leading causes of death in the world. “Margaret Chan Fung Fu-Chun, Director General WHO 2008”

“Tobacco is the only legally available consumer product which kills people when it is used entirely as intended”. (The Oxford Medical Companion, Oxford: Oxford University Press, 1994)

Situation in Pakistan

• Tobacco use is on the rise in Pakistan• 36% of males and 9% of females do smoke (NHS 1996)• Smokeless tobacco is also a major issue here• Cigarette industries pay 140 billion rupees in taxes

and source of livelihood for more than 1.2 million people

• 32% of house officers do smoke in Karachi• 22%nmale and 3.8% of females reported current

smokers at Karachi• 21.5% general students were reported using tobacco in

all forms in a study at Karachi• Tobacco associated cancers in Karachi are 38.3% in

males and 40% in females

Why do people smoke?

Different forms of tobacco

Smoked Tobacco

Smokeless tobacco

Second hand or passive smoking

Smoked tobacco

• Bidi:– Small hand-rolled cigarettes – Three times more carbon

monoxide and nicotine– Five times more tar – Three-fold higher risk of oral

cancer– Increased risk of lung, stomach

and esophageal cancer

• Shisha:– Tobacco mixed with flavorings

and smoked from hookahs – More popular in youths of

Karachi– Linked to lung disease,

cardiovascular disease and cancer

• Second hand or passive smoking– 2 hours is smoky office =4

cigarettes smoked– Two hours in non smoking area

of a restaurants even= 2 cigarettes

– 24 hours with a pack a day smokers = 3 cigarettes

– 3,400 lung cancer deaths and 46,000 heart disease deaths a year in US

– 430 sudden infant deaths– 24500 LBW,71900 preterm

deliveries & 2K childhood asthma

In children:brain tumors, middle ear disease, lymphoma, impaired lung function, asthma, sudden infant death syndrome, leukemia, and lower respiratory illness

Common Problems in Adults due to Passive smoking:stroke, nasal sinus cancer, coronary heart disease, lung cancer, atherosclerosis, COPD, asthma, pre-term delivery & low birth weight babies

• Tobacco in Pakistan is responsible for 90% of Lung Cancers, 90% of COPD, 40% of

overall cancers and 20 other fatal diseases • We are still in the early phase of Tobacco

epidemic, • Yet the full impact of tobacco is awaited

Tobacco Dependence:A cluster of behavioral, cognitive and physiological phenomena that develop after repeated use and typically include a strong desire to smoke, difficulty in controlling its use, persisting in its use despite harmful consequences, increased tolerance to nicotine, and a (physical) withdrawal state (PCS)

• 4000 Toxic Substances• Potent Carcinoges like Nitorsamines,

aromatic hydrocorbons• CO, Tar, ammonia, nitrogen oxide,

hydrogen cyanide and nicotine

Benefits of Stopping smoking?• A reduced risk of dying early

• a reduced risk lung cancer ,CAD, CVA, COPD & other cancers

• Improved respiration•Reduced risks of complications in

pregnancy and childbirth • Improvement in some mental

health symptoms • Fewer sick days off work

• Improvement in recovery from surgery and reduced perioperative

risk • A reversal of the risks of

smoking if cessation is achieved by the age of 35

Stopping smoking will also: • Set a good example for children

and young people (children of non-smokers are less likely to

become regular smokers) • Improve the health of young children of parents who have

ceased smoking • Save money

Patient # 1

• A 8 year old child is brought by his father in your clinic with the upper respiratory tract symptoms– Boy is allergic to smoke & dust

– Your clinical impression is allergic rhinitis

– You ask about any smoker in family

– Father confess that he smokes

o What is one of the major root cause of child’s illness evident from history?

General Approach

• Age , sex • How do u feel about your smoking?• When, why and how did you begin, • how many cigarettes per day, pack year• Previous quit attempts and reasons for failure and aids used? • Any smoker at home?• Past history• Family history • Social history• Personal history• Addictions• Drugs• Examination: Any thing left?

SCREENING TEST: 2 YES, SCREENING POSITIVE.

• Our patients CAGE score is 3 and fagerstrom is 6

• What should you do as a primary health care provider?

Clinical interventions for tobacco use and dependence

What can a health professional do?

• Do not smoke or use tobacco

• Take a history of smoking/tobacco use

• Give firm advice to patient who uses tobacco

• Learn ―how to counsel patients in order to make them quit smoking/tobacco use

• Educate the public regarding the hazards of active & passive smoking and other forms of tobacco

• Intervention as brief as three minutes increases the cessation rate• Average smoker attempting to quit five times before permanent

successAvailable interventions:

5As: one of the commonly used intervention by Family physicians5Rs: Motivational intervention for unmotivated persons5Ds: to combat withdrawal symptoms

5”As”: 1- Ask

• Adding smoking status as a vital sign to all patients’ charts

• Identification of all tobacco users and documentation of their smoking status at every office visit

• Ask all patents “do you smoke?” ,”Have you ever smoked?”– Take a brief history– Number of cigarettes per day– The year of starting smoking– Previous quit attempts and what happened– Presence of smoking related disease

“Have you ever been a smoker or used other tobacco products?Do you use tobacco now?How much?”

5”As” :2- Advice

• Clear, strong and personalized advise to stop smoking

• Advise firmly but in a no confrontational manner “the best thing you can do for your health is to quit smoking”

• Emphasize the personnel benefits of cessation– Improved health– Not exposing others to tobacco smoke– Positive role model for children and adolescents– Financial benefits

Strong—“As your clinician, I

need you to know that quitting smoking is the most important thing you can do to protect your health

now and in the future. The clinic staff and I

will help you.”

Clear—“It is important that you quit smoking (or using chewing

tobacco) now, and I can help you.”

“Cutting down while you are ill is not enough.” “Occasional

or light smoking is still dangerous.”

5”As” : 3-Asses

• Asses a person's’– Willingness and Barriers

– Smoking history and current level of nicotine dependence

– Timeline for quitting and about previous attempts

• “Have you ever tried to cut back on or quit smoking?

• Are you willing to quit smoking now? What keeps you away from quitting?

• How soon after getting up in the morning do you smoke?”

5”As” :3-Asses: Stages of Readiness to Change

• Pre-contemplation: – No intention to take action within next six

months– Unaware of the need to change; overestimate the

costs ,underestimate the benefits; Consider Reluctance(inertia), Rebellion and Rationalization

• Contemplation:– Considering change within the next six months– Ambivalent about change; perceives that costs

equal benefits

5”As”:3-Asses: Stages of Readiness to Change

• Preparation/determination: – Planning to take action within the next month– May have already made steps towards change– Often concerned about failure

• Action:– Actively changing (first six months of new behavior)– Needs vigilance to

• Prevent relapse • Encouragement to keep up the momentum

• Maintenance:– More than six months since behavior change– Reminders about high-risk situations

5”As”:4-Assist: Readiness to change

• Assist according to patients readiness to change

Not readyEncourage patient to think about their smoking, offer

help, offer written material offer referral

Not sure:Encourage patient contemplate and help to reflect on

the pros and cons of smoking, plus offer help as above

Ready/action:Affirm and encourage the decision to quit, help the

patient to develop a quit plan

Help set a quit date

5”As” :4-Assist: Anticipate challenges

• Help patients to anticipate difficulties and encourage them to prepare their social support systems and their environment

• “I would like to help you quit. Can I tell you aboutSome of the things we know can increase your odds of success?”• “Are you worried about anything in particular

whenIt comes to quitting? • Do you worry about cravingsOr weight gain?”

• Our patient is not much convinced to quit smoking what to do?

For the patient unwilling to quit

• Patients unwilling to make a quit attempt during a visit may:

– Lack information about the harmful effects of tobacco use

– No knowing much about benefits of quitting;

– Lack the required financial resources;

– Have fears or concerns about quitting, or may be demoralized because of previous relapse

• These patients may respond to brief motivational interventions that are based on principles of motivational interviewing

– (1) express empathy

– (2) develop discrepancy

– (3) roll with resistance

– (4) support self-efficacy

Motivational Intervention for the patient unwilling to quit/ for Enhancing

Motivation….

5”As”4- Assist:5-Rs

• 1-Relevance

– Encourage the patient to indicate why quitting is personally relevant, such as children at home, money saved by quitting smoking, history of smoking related illness

• 2-Risks:

– Advise the patient of the harmful effects ,both to the patient and to others

Acute risks: Shortness of breath,

Exacerbation of asthma, Increased risk of respiratory

infections, Harm to pregnancy, Impotence, Infertility.

5”As” :4-Assist: 5Rs

• 3-Rewards– Identify benefits of

stopping tobacco use– Improved health– Improved sense of smell– Save money– Set a good example for

children– Reduced wrinkling/aging

of skin

• 4-Road blocks– Barriers to cessation – Other smokers in the home

or workplace– Failed quit attempts– Severe withdrawal

symptoms/ stress– Psychiatric comorbidity– Low motivation– Weight gain– Enjoyment of smoking

• 5-Repetations:– Motivational interventions

repeated every time

5”As”: 4-Assist: Willing to quit

• Help develop a quit plan• Set a quite date• Tell family and friends for support• Anticipate challenges &discuss challenges / triggers• Remove tobacco products• Avoid

– Alcohol use– Express to tobacco

• Provide supplementary materials• Give nutritional advice• Physical activity may help• Recommend the use of approved pharmacotherapies

5”As” :5-Arrange

• Elicit the benefits ask to anticipate and problem

• Schedule follow up contacts with in one week after quit date– Person – Telephone quit-line

• Four visits or calls are evidence based• Congratulate progress success• Identify problems and anticipate challenges• Evaluate pharmacotherapy use/ problems

• Our patient is willing to quit

• Quit motivated

• Seeks your help

• How will you help him

Algorithm for treating tobacco use

Pre-interventional Counseling

• Discuss

– Tobacco withdrawal S/S

– Benefits of quitting smoking

– Behavioral interventions

– Non-pharmacological and pharmacological aid

– Maintenance/ follow up plans/ relapses

Method for smoking cessation

Non pharmacological

– Behavioral cessation and therapies

– Individual , group, or telephone counseling

• Pharmacological– Nicotine replacement

therapy, transdermal, nasal spray, inhaler, gum, lozenges

– Bupropion sr (zayban)

– Chantix

– Clonidine, transdermal, oral

– Nortryptelline

– Anxiolytic agents

Behavioral intervention

• Brief advice

• Group counselling

• Telephone counselling

• Web based programs

Cognitive strategies

• Keep a diary for one or several days prior to quit day(more aware of their smoking patterns and risk situations)

• Coping with craving

Most common nicotine withdrawal symptoms

• Depression:– Smokers have more

likelihood of depression, hindrance in quitting

– Smoking cessation may trigger depression

– Do screen for depression – Bupropion (zyban) is helpful

• Irritability, anxiety, restlessness– Peak within the first week of

abstinence and last two to four weeks

– Decrease caffeine intake & nrts can be helpful

• Weight gain:– Most smokers gain fewer

than 10 lb(4.5 kg) after quittingWeight gain can vary (10

percent will gain30 lb [13.5 kg])– Concern about weight gain

may interfere– Sustained-release bupropion

or an NRT– (Particularly gum or

lozenges) delay weight gain while in use

– Monitor and adjust food intake/exercise balance

Behavioral strategies cope with craving

• Suggest 4Ds

– Delay acting on the urge to smoke, after five minutes the urge to smoke weakens and your resolve to quit will come back

– Deep breath: take a long slow breath in and slowly release it out again, repeat three times

– Drink water slowly holding it in your mouth a little longer to savour the taste

– Do something else to take your mind off smoking, doing some excerscise is good alternative

First line pharmacotherapies

• Nicotene replacement therapy– Trandermal patch

– Chewing gums

– Lozenge

– Inhaler

– Nasal spray

Non nicotene therapy– Vernacillene

– Buprpion

Second line pharmacotherapy

• Nortryptelline

• Clonidine

First-line therapies for smoking cessation in adults

• Nicotine gum– Available in 2-mg and 4-mg (per

piece) doses– Patients smoking less than 25

cigarettes per day: 2 mg– Patients smoking 25 or more

cigarettes per day: 4 mg– Maximum dosage: 24 pieces per

day– Over the counter– may delay weight gain; – Difficult to use with dentures,

partials, or fillings– FDA pregnancy category C– Side effects: gastrointestinal

distress; mouth or throat irritation

• Nicotine lozenge – Heavy smokers: 4 mg– Light smokers: 2 mg– Maximum: 20 lozenges per day– Over the counter– May delay weight gain;; – Contains 25 percent more

nicotine than gum– FDA pregnancy category D– Side effects: nausea, heartburn,

headache

• Nicotine patch – Doses vary and should be

tapered as therapy progresses– Heavy smokers: 21 mg per day– (Initial dosage)– Light smokers or those weighing

less than 100 lb (45 kg): 10 to 14 mg per day (initial dosage)

– Over the counter– Treatment of up to eight weeks – Site of patch should be changed

daily; – 16- and 24-hour patches have

comparable effectiveness; adolescents may require lower starting dosages because of body habitus and overall smoking patterns (e.G., Less than one-half pack per day)

– FDA pregnancy category D– Side effects: skin reactions (up

to 50 percent), headaches, insomnia (decreased if patient removes patch at night)

• Nasal spray – One dose consists of two 0.5-mg

sprays (one in each nostril)– Initial dosage is one or two

doses per hour (minimum of eight doses per day), increasing as needed for symptom relief

– Maximum: 40 doses per day (five doses per hour)

– Dependence potential is intermediate between other nicotine replacement therapies and cigarettes

– FDA pregnancy category D– Side effects: moderate to severe

nasal irritation within the first two days (94 percent) that often continues throughout use

Bupropion

• Inhibitor of neuronal reuptake of noradrenaline and dopamine– Limits craving(substitution of stimulant effects of

nicotine)

• Marketed as antidepressant and decrease the desire to smoke observed in depressed patients

• Double the success rate of quitting compared to placebo

• Equally effective in patients who are not depressed

Bupropion: Patients issues

• Insomnia

• Dry mouth

• Tremors

• Rashes

• Weight loss

• Seizures

• Hypertension

Varenicline/ chantix

• High affinity partial nicotine acetylcholine receptor antagonist

• specifically designed for smoking cessation

• Alleviates the symptoms of craving and withdrawal , but produce much weaker effect than nicotine

• Prevents inhaled nicotine from a cigaratteactivating the ---- receptors and blocks the pleasurable effect of smoking

• Varenicline (chantix): Continued– Days 1 to 3: 0.5 mg once per day– Days 4 to 7: 0.5 mg twice per day– Day 8 to end of treatment: 1 mg twice per day– Begin therapy one week before quit date and continue for

12 weeks; an additional 12 weeks can be added if quit attempt is successful to increase chances of long-term abstinence

– Should not be combined with a nicotine replacement therapy;

– FDA pregnancy category C– Side effects: headache, nausea (dose related), insomnia,

abnormal dreams, flatulence increased risk of cardiovascular events in smokers with cardiovascular disease should be discussed with patients

– FDA boxed warning: may cause serious neuropsychiatric symptoms in patients, including changes in behavior, hostility, agitation, depressed mood, suicidal thoughts and behavior, and attempted suicide; patient should be monitored closely

Second line treatment

• Nortryptylline– Tricyclic antidepressant

– Mechanism of action in smoking cessation is likely to be separate from antidepressant effect

– Dose is 75 mg per day for 12 weeks

– Side effects• Dry mouth, sedation,over dose risks

– Not registered for smoking cessation in australia

Second line treatment

• Clonidine

– Antihypertensive, centrally acting alpha agonist

– Minimal use for this indication in Australia

Possible future options

• Nicotine vaccines in development.

• The selective type 1 cannabinoid receptor antagonist Rimonabant .

• The Nicotine receptor partial agonist Cystine.

• They have demonstrated some efficacy in studies, but as yet there is insufficient evidence for their use in tobacco cessation.

Follow up

• First visit: after 1 week of quit date.

• Second visit: within the same month.

• At 2 month : telephone call or letter of encouragement.

• At 3 month : cessation validation by expired air CO.

• At 5 month : telephone call or letter of encouragement

• At 6 month : cessation validated by expired air CO

• At 9 month : telephone call or letter of encouragement.

• At 12 month :cessation validated by expired air CO
