Practical Pearls for
Primary Care
Evaluation and Treatment
of Hypertension
A 58 yo man is diagnosed with
hypertension. His BP’s are 160/96, 160/100,
and 158/96 on 3 outside readings. He has
been on a low sodium diet and he is not obese.
PMH- hyperlipidemia, GERD and gout. What
would be the most appropriate treatment?
A) Low salt diet and exercise
B) Hydrochlorathiazide
C) Doxazosin
D) ACE inhibitor
When Thiazides Are Not A
Good Choice
History of Gout
 Creatinine > 1.6
 Lithium use

Diuretic Choice
Strongly consider chlorthalidone
 Long acting, great data
 Major drawback has been hypokalemia

Pearls in the Treatment of Hypertension




Remember when not to use hydrochloathiazide:
renal insufficiency , gout
Chlorthalidone has longer half life, better efficacy
than HCTZ
Spironolactone avoids hypokalemia, avoid in
renal insufficiency, be careful if patient on an
ACEI or ARB. Remember gynecomastia
Losartan can lower uric acid
A 60 yo man presents for follow-up of
hypertension. He has been taking medication
(Lisinopril) for the past 3 months. His most recent
outside blood pressure readings are 156/94, 150/96,
158/92. PMH: Type 2 DM, GERD, depression. Meds:
Lisinopril 20mg qd, Rabeprazole 20mg qd, Sertraline
50 mg qd, Glyburide 10 mg qd.
What do you recommend?
A) No changes in therapy
B) Increase Lisinopril to 20 mg BID
C) Add Hydrochlorathiazide 12.5 mg qd
D) Add Amlodipine (Norvasc) 5mg qd
E) Add Clonidine .1mg BID
Combination Therapy



Low doses of thiazide can be very effective in
combination with ACE inhibitors (12.5 mg of
thiazide)
Thiazide ACE combination can be further
enhanced by moderate dietary salt restriction
ACE/Amlodipine combination may have CV
benefi slightly better than ACE/diuretic in high
risk diabetic paients
A 58 yo woman is seen for treatment of hypertension. She
has not ever had good control of her hypertension since
treatment was started 2 years ago. She has been taking her
medications faithfully. Meds: Felodipine (Plendil), Atenolol ,
Clonidine, and Losartan (Cozaar). On exam her BP is 200/106
P-55.Labs- BUN 30, Cr 2.0, Na 137, K 4.0. ECG- LVH
What would you recommend?
A) Increase felodipine from 10mg a day to 10mg BID
B) Increase losartan from 50mg BID to 100mg BID
C) Add hydrochlorathiazide 12.5 mg qd
D) Add hydrochlorathiazide 25 mg qd
E) Add furosemide 40 mg BID
Refractory Hypertension
Occurs in 5% of hypertensive patients
 Always carefully evaluate for medication
adherence.
 Worse with increasing obesity
 Think of secondary causes
 Sleep apnea
 Ingestion of substances that interfere with
treatment (especially NSAIDS)

Treatment of Refractory
Hypertension
Most have too much volume.
Furosemide extremely useful, especially
if renal insufficiency present
 Strongly consider using spironolactone
 Simplify regimens if possible to improve
adherence

How Can You Tell What
Kind Of Headache It Is?

A 29 yo woman is evaluated for headaches.
She reports having headaches about twice a
month. She feels pain behind her right eye
and frequently pain on her forehead. Her
headaches often get better with 550 mg of
Naprosyn. She has never had visual problems
or nausea with her headaches. The
headaches are worse with exercise. About
once a month the headache is bad enough to
force her to leave work early.
What is the Most Likely Type of
Headache?
A)Migraine
B)Cluster
C)Muscle tension
D)Nitrate headache
Clinical Features of Tension Type
Headache
Mild Headache
 Often described as tightness, vice like
 Neck to forehead can be involved
 Often helped by NSAIDS
 Worse during times of stress
 Not disabling

A 29 yo woman presents for evaluation. She reports
that she has frequent headaches over the past 12
months that include pressure pain on her forehead,
under her eyes and over her cheeks. She usually
has nasal congestion as well. She has not had any
fevers or purulent nasal discharge. What is the
most likely problem?
Cluster headaches
Migraine headaches
Sinus headaches
Tension headaches
“Sinus” Headaches Are Usually
Migraine Headaches



2991 patients screened who reported at least 6
headaches during the previous 6 months self
diagnosed or physician diagnosed as sinus
headaches
88% of these patients met IHS criteria for migraine
HA (80%) or migrainous criteria (8%).Most common
sx patients reported were sinus pressure (84%), sinus
pain (82%) and nasal congestion (63%)
Arch Intern Med 2004;164 (16): 1769-1772
Sinus, Allergy and Migraine
Study



100 patients recruited who believed they had sinus
headaches. All received a detail history and PE and
given headache diagnosis based on HIS criteria
Final diagnosis were as follows: Migraine with or
without aura 52%, probable migraine 23%, chronic
migraine with medication overuse HA 11%,
nonclassifiable HA 9%. 76% of migraine patients
reported pain in the distribution of the 2nd division of
the trigeminal nerve and 62% experienced bilateral
forehead and maxillary pain with their HA’s.

Treatment of Sinus Headache as
Migraine: The Diagnostic Utility of
Triptans



To determine the response rate to triptans in
alleviating “sinus headache” in patients with
endoscopy and CT negative sinus exams
Prospective study of patients with physician or patient
self diagnosed sinus headaches with negative
workup all treated with triptans
54 patients enrolled, 38 completed follow up. 31
patients (82%) had significant reduction in headache
pain with triptan use, 35 (92%) had a response to
migraine directed therapy.

Treatment Pearls for Migraine
Role of Metoclopramide
Good efficacy when combined with
NSAID. Equivalent to sumatriptan oral if
patient has nausea.

oral migraine treatments

Metoclopramide vs Hydromorphone


Retrospective cohort study to evaluate metoclopramide vs
hydromorphone for initial ED treatment of migraine
200 patients, 51 received IV or IM hydromorphone, 95
received IV metoclopramide and 54 received a different
medication.
Using a 1-10 pain scale, mean pain scale reductions were
2.3 for hydromorphone, 3.7 for metoclopramide and 2,8 for all
other meds (p<.001).
Less rescue meds and faster ED discharge with
metoclopramide
J Pain 2008;9 (1): 88-94.
Sumatriptan + Naproxen
Sustained pain free response 2-24 hours, the
combination is superior to either drug by itself
(p<.01) . Dose used 85 mg
sumatriptan/500mg naproxen (1)
 In patients with poor prior response to triptans,
the combination was significantly more
effective than placebo (p<.001) (2)
