Nicotine Addiction
Tobacco users maintain a minimum serum
nicotine concentration in order to
Prevent withdrawal symptoms
Maintain pleasure/arousal
Modulate mood
Users self-titrate nicotine intake by
Smoking more frequently
Smoking more intensely
Obstructing vents on low-nicotine brand cigarettes
Nicotine Pharmacodynamics:
Withdrawal Effects
Depression
Insomnia
Irritability/frustration/anger
Anxiety
Difficulty concentrating
Restlessness
Increased appetite/weight gain
Decreased heart rate
Cravings*
* Not considered a withdrawal symptom by DSM-IV criteria.
Most symptoms
peak 24–48 hr
after quitting and
subside within
2–4 weeks.

FDA MedWatch 11/20/2007
11/20/2007] FDA informed healthcare professionals of reports
of suicidal thoughts and aggressive and erratic behavior in
patient who have taken Chantix, a smoking cessation product.
There are also reports of patients experiencing drowsiness that
affected their ability to drive or operate machinery. FDA is
currently reviewing these cases, along with other recent reports.
A preliminary assessment reveals that many of the cases reflect
new-onset of depressed mood, suicidal ideation, and changes in
emotion and behavior within days to weeks of initiating Chantix
treatment. The role of Chantix in these cases is not clear because
smoking cessation, with or without treatment, is associated with
nicotine withdrawal symptoms and has also been associated with
the exacerbation of underlying psychiatric illness.
Patients taking this product should report behavior or mood
changes to their doctor and use caution when driving or
operating machinery until they know how quitting smoking with
Chantix may affect them.

Figure 1—Algorithm for the metabolic management of type 2 diabetes.
a - Check A1C every 3 months until 7% and then at least every 6 months.
b - Associated with increased risk of fluid retention, CHF, and fractures. Rosiglitazone, but probably not
pioglitazone, may be associated with an increased risk of myocardial infarction.
c - Although three oral agents can be used, initiation and intensification
of insulin therapy is preferred based on effectiveness and lower expense.
MedWatch 2/20/2007
• Glaxo SmithKline (GSK) notified healthcare professionals of the
results of a randomized, double-blind parallel group study
[ADOPT] of 4,360 patients with recently diagnosed type 2 diabetes
mellitus followed for 4-6 years to compare glycemic control with
rosiglitazone relative to metformin and glyburide monotherapies.
– Significantly more female patients who received
rosiglitazone experienced fractures of the upper arm, hand,
or foot, than did female patients who received either
metformin or glyburide.
– At GSK's request, an independent safety committee reviewed
an interim analysis of fractures in another large; ongoing;
controlled clinical trial and preliminary analysis was reported
as being consistent with the observations from ADOPT.
• Takeda/Lilly have also gone back and the same association has
been seen with pioglitazone
• Healthcare professionals should consider the risk of fracture when
initiating or treating female patients with type 2 diabetes mellitus
withrosiglitazone and pioglitazone.
MedWatch 5/21/07
• The FDA issued a Safety Alert along with a 42
trial meta-analysis in the NEJM that reported a
43% increase in acute MI related to the use of
rosiglitazone compared to other antidiabetic
agents.
• The FDA had previously received a GSK metaanalysis which had also shown a 31% increase
in the risk of acute MI with rosglitazone
(1.99% vs 1.51% or a 31% RRI or an NNH of
about 200)
FDA Advisory Committees 7-30-07
• Voted 22-1 to allow rosiglitazone to remain on the
market
• Voted 20-3 to recommend updated CV warnings in
labeling and that they was a clear signal of harm
including ischemic heart disease
• Panel members also bemoaned the fact that the FDA
had not had foresight to mandate appropriate trials
• On-going trials RECORD, ACCORD and BARI-2D are
under-powered and not designed to answer the key
questions about whether ischemic events will be higher
and which patient sub-sets will be affected
• FDA analysis suggested that nitrate use and concurrent
insulin therapy may increase the risk of ischemic heart
disease with rosiglitazone
FDA Alert 11/19/2007
• Recommendations and Considerations for Healthcare
Professionals/Label Change
• Rosiglitazone may cause myocardial ischemia in some
patients.
• Co-administration of rosiglitazone and insulin is not
recommended. A higher risk of myocardial ischemia was
observed in controlled, double-blind clinical trials where
rosiglitazone was added on to established insulin therapy.
• Rosiglitazone is not recommended for patients with heart
disease who are taking nitrates. A subgroup analysis of 42
clinical studies identified that patients with heart disease
who are taking nitrates are at an increased risk of
myocardial ischemia.

European Assoc for the Study of
Diabetes (EASD) Consensus Report 9-06
Calls for urgent action to drastically improve the
management of DM, particularly urging the
increased acceptance of insulin
All patients with Type 2 DM, if they live long
enough, will need insulin
Recent survey found that the major patient barrier
to achieving optimal blood sugar control was
patient resistance to insulin
European Assoc for the Study of
Diabetes (EASD) Consensus Report 9-06
Clinical research shows that one half of patients
who are not at goal on oral medications are
delaying at least 4-6 years to add insulin
The new non-injectable insulin could be a way
to increase patient acceptance and thus lead to
better outcomes

NPH
Insulin Glulisine - Apidra
A rapid acting human insulin analog with
lysine for asparagine at B3 and glutamic acid
for lysine at B29 from Sanofi-Aventis
Appears to be similar to both insulin lispro
and insulin aspart
Limited data on mixing (NPH can be mixed
immediately before injection and draw up
glulisine first
Maybe less risk of line occlusion in pumps
and less variation is response with changes in
BMI?
Insulin Detemir - Levemir
A soluble, neutral insulin in which the B29
lysine residue has been covalently bound to a 14
carbon fatty acid and it binds extensively
(~98%) to albumin and has a bioavailability of
~ 60% from Novo-Nordisk (increased dosage
when changing insulins?)
Peak levels occur in ~ 4-6 hrs and duration is up
to ~ 20 hrs (dosed once or twice a day)
Should not be mixed with other insulins
Maybe less glucose excursions and weight
gain?

New UK Guidelines for Hypertension
NICE(Nat Inst for Health and Clinical
Excellence)/BHS (British Hypertension Soc)
Hypertension Guidelines issued 6/28/2006 omit beta
blockers for routine use including first, second or
third line for the treatment of patients with
uncomplicated hypertension
In patients 55 y/o or over or black patients of any
age, the first choice for initial therapy should be
either a thiazide type diuretic or CCB
In patients younger than 55, the first choice for
initial therapy should be an ACEI
If treatment with three drugs is required, the
combination of an ACEI, thiazide and CCB should
be used

Atenolol in HBP: Is It a Wise
Choice?
The authors conclude
“Our results cast doubt on atenolol as a suitable drug for
hypertensive patients. Moreover, they challenge the use of
atenolol as a reference drug in outcome trials in
hypertension.”1
A more recent editorial by ASCOT Investigator Dr
Beevers states
“Surely, the era of beta blockers for hypertension is
over.”2
Atenolol is also not a good once-a-day agent as
the
T1/2 is only about 6–7 hours

Beta-blockers for Hypertension
Cochrane Database of Systematic Reviews 2007, Issue 1, Art
No.:CD002003
The available evidence does not support the use of betablockers as first-line drugs in the treatment of
hypertension.
13 randomized, controlled trials in more than 91,000 patients
This conclusion is based on the relatively weak effect of
beta-blockers to reduce stroke and the absence of an effect
on coronary heart disease when compared to placebo or no
treatment. More importantly, it is based on the trend
towards worse outcomes in comparison with calcium
channel blockers, renin-angiotensin system inhibitors, and
thiazide diuretics.
Most of the evidence for these conclusions comes from
trials where atenolol was the beta-blocker used (75% of
beta-blocker participants in this review).
However, it is not known at present whether beta-blockers
have differential effects on younger and elderly patients or
whether there are differences between the different sub-
Nebivolol Bystolic by Forest
Labs
Nebivolol is the newest cardioselective
beta blocker that is also vasodilating but
not by way of also having alpha blocking
activity
A recent study from Italy (Hypertension
2007;50:652-6) demonstrates that nebivolol
stimulates nitric oxide production in the
heart and that this action is exerted by a
signaling pathway starting from the
activation of beta 3-adrenergic receptors and
leading to the over-expression of inducible
nitric oxide synthase.
Nebivolol Bystolic
INDICATIONS: Nebivolol is indicated
for the treatment of hypertension.
Nebivolol may be used alone or in
combination with other antihypertensive
agents. BP effects are similar to other
beta blockers
It also is under evaluation for use in the
treatment of heart failure.
Nebivolol Bystolic
SENIORS Trial (European Heart Journal 2005, 26(3):215-25)
2128 patients aged >/=70 years with a history of heart failure
(hospital admission for heart failure within the previous year or
known ejection fraction </=35%)
1067 to nebivolol (titrated from 1.25 mg once daily to 10 mg once
daily), and 1061 to placebo
The primary outcome was a composite of all cause mortality or
cardiovascular hospital admission (time to first event).
Mean duration of follow-up was 21 months
Mean age was 76 years (SD 4.7), 37% were female, mean ejection
fraction was 36% (with 35% having ejection fraction >35%), and
68% had a prior history of coronary heart disease
The mean maintenance dose of nebivolol was 7.7 mg and of
placebo 8.5 mg
The primary outcome occurred in 332 patients (31.1%) on nebivolol
compared with 375 (35.3%) on placebo [hazard ratio (HR) 0.86, 95%
CI 0.74-0.99; P=0.039]. NNT 24
Death (all causes) occurred in 169 (15.8%) on nebivolol and 192
(18.1%) on placebo (HR 0.88, 95% CI 0.71-1.08; P=0.21). NNT 44
Nebivolol Bystolic
A subsequent analysis of the SENIORS trial
(Am Heart J 2007;154:109-15) showed that
nebivolol reduced the risk of death or
cardiovascular (CV) hospitalization in elderly
patients with heart failure (HF) in a dose
related manner.
RESULTS: After adjustment, all-cause mortality or
CV hospitalization was significantly reduced in the
10 mg dose group compared with placebo (hazard
ratio [HR] 0.75, 95% CI 0.63-0.90) which was similar
to the medium dose group (HR 0.73, 95% CI 0.521.02).
The low dose group had an apparently lower benefit
(HR 0.88, 95% CI 0.64-1.20), whereas patients unable
to tolerate any dose of nebivolol had an increased
risk of death or CV hospitalization (HR 1.95, 95% CI
1.38-2.75).
Nebivolol Bystolic
It is available as 2.5, 5, and 10 mg unscored
tablets. Cost ~$60.00/30 tablets
Additional studies are needed to address the
long-term benefits of nebivolol for
hypertension, to compare nebivolol with
other beta-adrenergic blockers for heart
failure, and to investigate the clinical
relevance of nitric oxide-mediated
vasodilation
ALISKIREN
Tekturna ( Novartis )
Aliskiren is a direct renin inhibitor, decreasing plasma
renin activity and inhibiting the conversion of
angiotensinogen to angiotensin
Oral bioavailability is 2.6%.
The mean elimination half-life of aliskiren is 25 to 58 hours
INDICATIONS: Aliskiren is indicated for the treatment of
hypertension. It may be used alone or in combination with
other antihypertensive agents. (Use with maximal doses of
angiotensin-converting enzyme (ACE) inhibitors has not
been adequately studied)
Aliskiren has produced blood pressure reductions comparable with
angiotensin receptor blockers and ACE inhibitors. It has also
shown increased blood pressure–lowering effects in combination
with these agents.
Whether it has any effects on outcome measures such as heart
attack, stroke, or nephropathy is yet to be determined
Clinical Pharmacology:
Mechanism of Action (cont’d)
ALISKIREN-Tekturna
Pregnancy Category C for first trimester exposure and in
Pregnancy Category D for second and third trimester
exposure (box warning). Drugs that act directly on the
renin-angiotensin system can cause fetal injury or death
when used during the second or third trimesters
Hyperkalemia (serum potassium more than 5.5 mEq/L)
occurred infrequently with aliskiren monotherapy (0.9%
compared with 0.6% with placebo). Increases in serum
potassium were observed more frequently with use in
combination with ACE inhibitors in diabetic patients
(5.5%)
Coadministration with furosemide was associated with a
30% reduction in the furosemide AUC and a 50% reduction
in furosemide peak concentration. The therapeutic effects
of furosemide may be reduced upon initiation of aliskiren
therapy
ALISKIREN - Tekturna
The most common adverse reactions observed in aliskiren
studies included headache, dizziness, fatigue, and diarrhea
diarrhea was much higher in patients treated with aliskiren 600 mg
(9.5%) than in those treated with aliskiren 150 mg (1.2%), 300 mg
(2.3%), or placebo (1.2%)
Significant adverse reactions occurring less frequently
included angioedema, edema, rash, elevated uric acid,
gout, and renal stones.
Cough occurred slightly more frequently with aliskiren
(1.1%) than with placebo (0.6%)
150 mg tabs $74/30 and 300 mg tabs $94/30
Advantages over ACE inhibitors and angiotensin receptor
blockers have not been established. Until outcome data are
available, use should be reserved for those patients failing
to respond adequately to or tolerate agents from those drug
classes.

Select Information About GARDASIL
• GARDASIL is a vaccine indicated in girls and women 9 to 26 years of age for the
prevention of cervical cancer, precancerous or dysplastic lesions, and genital
warts caused by HPV Types 6, 11, 16, and 18.
• Individuals who were already infected with 1 or more vaccine-related HPV types
prior to vaccination were protected from disease caused by the remaining
vaccine HPV types.
• GARDASIL is contraindicated in individuals who are hypersensitive to the active
substances or to any of the excipients of the vaccine.
• Vaccination with GARDASIL does not substitute for routine cervical cancer
screening, and women who receive GARDASIL should continue to undergo
screening per standard of care.

ACIP Recommendations* for Zoster
Vaccine*
• Single dose of zoster vaccine for adults 60 years of
age and older whether or not they report a prior
episode of shingles
• Persons with a chronic medical condition may be
vaccinated unless a contraindication or precaution
exists for their condition
* Recommendations, October 2007
70
Screening for Zoster Vaccine Eligibility
• Screening for a history of varicella disease is NOT
necessary or recommended to administer zoster
vaccine to a person 60 years of age or older
• Persons born in the U.S. before 1980 can be assumed
to be immune regardless of their recollection of
chickenpox
• A trial is underway to evaluate the efficacy and safety in
patients 50-60 yrs of age

Reclast (zoledronic acid) Injection
• A randomized, double-blind, placebo -controlled,
multinational study of 7736 women aged 65-89 years
(mean age of 73) with either: a femoral neck BMD Tscore less than or equal to -1.5 and at least two mild or
one moderate existing vertebral fracture(s); or a
femoral neck BMD T-score less than or equal to -2.5
with or without evidence of an existing vertebral
fracture(s).
• The two primary efficacy variables were the incidence
of vertebral fractures at 3 years and the incidence of
hip fractures over a median duration of 3 years.

• Reclast demonstrated a 1.1% absolute reduction and
41% relative reduction in the risk of hip fractures over a
median duration of follow-up of 3 years. The hip
fracture event rate was 1.4% for Reclast -treated
patients compared to 2.5% for placebo -treated
patients.
76
Reclast (zoledronic acid) Injection
• A randomized, double-blind, placebo-controlled trial,
1065 patients were assigned to receive yearly
intravenous zoledronic acid (at a dose of 5 mg), and
1062 patients were assigned to receive placebo. The
infusions were first administered within 90 days after
surgical repair of a hip fracture. All patients (mean age,
74.5 years) received supplemental vitamin D and
calcium. The median follow-up was 1.9 years. The
primary end point was a new clinical fracture.

Reclast (zoledronic acid) Injection
• Results The rates of any new clinical fracture were
8.6% in the zoledronic acid group and 13.9% in the
placebo group, a 35% risk reduction with zoledronic
acid (P=0.001); the respective rates of a new clinical
vertebral fracture were 1.7% and 3.8% (P=0.02), and
the respective rates of new nonvertebral fractures were
7.6% and 10.7% (P=0.03). In the safety analysis, 101
of 1054 patients in the zoledronic acid group (9.6%)
and 141 of 1057 patients in the placebo group (13.3%)
died, a reduction of 28% in deaths from any cause in
the zoledronic acid group (P=0.01).
