Normal physiologic patterns of glucose and
insulin secretion in our body
30
How Is Insulin Normally Secreted?
31
  • The rapid early rise of insulin secretion in
    response to a meal is critical,
  • because
  • it ensures the prompt inhibition of endogenous
    glucose production by the liver
  • disposal of the mealtime carbohydrate load, thus
    limiting postprandial glucose excursions.

The time course of action of any insulin may vary
in different individuals, or at different times
in the same individual. Because of this
variation, time periods indicated here should be
considered general guidelines only.

Inhaled Insulin
Inhaled Insulin
  • Approved in the U.S. in 2006 for the treatment of
    type 2 diabetes
  • However, published studies to date have not
    demonstrated whether inhaled insulin can lower
    HbA1c to 7, either
  • As monotherapy or
  • In combination with an injection of long-acting
    insulin

Nathan DM et al. Diabetes Care 200629(8)1963-72.
54
Advantages of Insulin Therapy
  • Oldest of the currently available medications,
    has the most clinical experience
  • Most effective of the diabetes medications in
    lowering glycemia
  • Can decrease any level of elevated HbA1c
  • No maximum dose of insulin beyond which a
    therapeutic effect will not occur
  • Beneficial effects on triglyceride and HDL
    cholesterol levels

Disadvantages of Insulin Therapy
  • Weight gain 2-4 kg
  • May adversely affect cardiovascular health
  • Hypoglycemia
  • However, rates of severe hypoglycemia in patients
    with type 2 diabetes are low
  • Type 1 DM 61 events per 100 patient-years
  • Type 2 DM 1-3 events per 100 patient-years

The ADA Treatment Algorithm for
the Initiation and Adjustment of Insulin
64
Initiating and Adjusting Insulin
Hypoglycemia or FG gt3.89 mmol/l (70 mg/dl)
Reduce bedtime dose by 4 units (or 10 if dose
gt60 units)
Target range 3.89-7.22 mmol/L (70-130
mg/dL)
If HbA1c ?7...
If fasting BG in target range, check BG before
lunch, dinner, and bed. Depending on BG results,
add second injection (can usually begin with 4
units and adjust by 2 units every 3 days until BG
in range)
Continue regimen check HbA1c every 3 months
Recheck pre-meal BG levels and if out of range,
may need to add another injection if HbA1c
continues to be out of range, check 2-hr
postprandial levels and adjust preprandial
rapid-acting insulin
Continue regimen check HbA1c every 3 months
Nathan DM et al. Diabetes Care.
200629(8)1963-72.
65
Step One
Hypoglycemia or FG gt3.89 mmol/l (70 mg/dl)
Reduce bedtime dose by 4 units (or 10 if dose
gt60 units)
Target range 3.89-7.22 mmol/L (70-130
mg/dL)
If HbA1c ?7...
If fasting BG in target range, check BG before
lunch, dinner, and bed. Depending on BG results,
add second injection (can usually begin with 4
units and adjust by 2 units every 3 days until BG
in range)
Continue regimen check HbA1c every 3 months
Recheck pre-meal BG levels and if out of range,
may need to add another injection if HbA1c
continues to be out of range, check 2-hr
postprandial levels and adjust preprandial
rapid-acting insulin
Continue regimen check HbA1c every 3 months
Nathan DM et al. Diabetes Care.
200629(8)1963-72.
66
Step One Initiating Insulin
  • Start with either
  • Bedtime intermediate-acting insulin or
  • Bedtime or morning long-acting insulin

Insulin regimens should be designed taking
lifestyle and meal schedules into account
Nathan DM et al. Diabetes Care 200629(8)1963-72.
67
Step One Initiating Insulin, contd
  • Check fasting glucose and increase dose until in
    target range
  • Target range 3.89-7.22 mmol/l (70-130 mg/dl)
  • Typical dose increase is 2 units every 3 days,
    but if fasting glucose gt10 mmol/l (gt180 mg/dl),
    can increase by large increments (e.g., 4 units
    every 3 days)

Nathan DM et al. Diabetes Care 200629(8)1963-72.
68
Step One Initiating Insulin, contd
  • If hypoglycemia occurs or if fasting glucose lt
    3.89 mmol/l (70 mg/dl)
  • Reduce bedtime dose by 4 units or 10
    if dose gt60 units

Nathan DM et al. Diabetes Care 200629(8)1963-72.
While using basal insulin alone,never stop or
reduce ongoing oral therapy
69
After 2-3 Months
  • If HbA1c is lt7...
  • Continue regimen and check HbA1c every 3 months
  • If HbA1c is 7...
  • Move to Step Two

Step Two
Hypoglycemia or FG gt3.89 mmol/l (70 mg/dl)
Reduce bedtime dose by 4 units (or 10 if dose
gt60 units)
Target range 3.89-7.22 mmol/L (70-130
mg/dL)
If HbA1c ?7...
If fasting BG in target range, check BG before
lunch, dinner, and bed. Depending on BG results,
add second injection (can usually begin with 4
units and adjust by 2 units every 3 days until BG
in range)
Continue regimen check HbA1c every 3 months
Recheck pre-meal BG levels and if out of range,
may need to add another injection if HbA1c
continues to be out of range, check 2-hr
postprandial levels and adjust preprandial
rapid-acting insulin
Continue regimen check HbA1c every 3 months
Nathan DM et al. Diabetes Care.
200629(8)1963-72.
73
Step Two Intensifying Insulin
  • If fasting blood glucose levels are in target
    range but HbA1c 7, check blood glucose before
    lunch, dinner, and bed and add a second
    injection
  • If pre-lunch blood glucose is out of range,
  • add rapid-acting insulin at breakfast
  • If pre-dinner blood glucose is out of range,
  • add NPH insulin at breakfast or rapid-acting
    insulin at lunch
  • If pre-bed blood glucose is out of range,
  • add rapid-acting insulin at dinner

Nathan DM et al. Diabetes Care 200629(8)1963-72.
74
Making Adjustments
  • Can usually begin with 4 units and
    adjust by 2 units every 3 days until blood
    glucose is in range

When number of insulin Injections increase from
1-2..Stop or taper of insulin secretagogues
(sulfonylureas).
Nathan DM et al. Diabetes Care 200629(8)1963-72.
75
After 2-3 Months
  • If HbA1c is lt7...
  • Continue regimen and check HbA1c every
    3 months
  • If HbA1c is 7...
  • Move to Step Three

Nathan DM et al. Diabetes Care 200629(8)1963-72.
76
Step Three
Hypoglycemia or FG gt3.89 mmol/l (70 mg/dl)
Reduce bedtime dose by 4 units (or 10 if dose
gt60 units)
Target range 3.89-7.22 mmol/L (70-130
mg/dL)
If HbA1c ?7...
If fasting BG in target range, check BG before
lunch, dinner, and bed. Depending on BG results,
add second injection (can usually begin with 4
units and adjust by 2 units every 3 days until BG
in range)
Continue regimen check HbA1c every 3 months
Recheck pre-meal BG levels and if out of range,
may need to add another injection if HbA1c
continues to be out of range, check 2-hr
postprandial levels and adjust preprandial
rapid-acting insulin
Continue regimen check HbA1c every 3 months
Nathan DM et al. Diabetes Care.
200629(8)1963-72.
77
Step Three Further Intensifying Insulin
  • Recheck pre-meal blood glucose and if out of
    range, may need to add a third injection
  • If HbA1c is still 7
  • Check 2-hr postprandial levels
  • Adjust preprandial rapid-acting insulin

Nathan DM et al. Diabetes Care 200629(8)1963-72.
78
Premixed Insulin
  • Not recommended during dose adjustment
  • Can be used before breakfast and/or dinner if the
    proportion of rapid- and intermediate-acting
    insulin is similar to the fixed proportions
    available

Nathan DM et al. Diabetes Care 200629(8)1963-72.
79
Key Take-Home Messages
  • Insulin is the oldest, most studied, and most
    effective antihyperglycemic agent, but can cause
    weight gain (2-4 kg) and
    hypoglycemia
  • Insulin analogues with longer, non-peaking
    profiles may decrease the risk of hypoglycemia
    compared with NPH insulin
  • Premixed insulin is not recommended during dose
    adjustment

80
Key Take-Home Messages, contd
  • When initiating insulin, start with bedtime
    intermediate-acting insulin, or bedtime or
    morning long-acting insulin
  • After 2-3 months, if FBG levels are in target
    range but HbA1c 7, check BG before lunch,
    dinner, and bed,and, depending on the results,
    add 2nd injection (stop sulfonylureas here)
  • After 2-3 months, if pre-meal BG out of range,
    may need to add a 3rd injection
    if HbA1c is still 7 check 2-hr
    postprandial levels and adjust preprandial
    rapid-acting insulin.

81
  • Regimen 2

82
First calculate total daily dose of insulin
  • Body weight in kgs / 2
  • e.g an 80 kg person will require roughly about
  • 40 units / day.

83
Dose calculation..contd
  • Split the total calculated dose into 4 (four)
    equal s/c injections.
  • ¼ of total dose as regular insulin s/c half-hour
    ( ½ hr ) before the three main meals with 6 hrs
    gap in between.
  • ¼ total calculated dose as NPH insulin s/c at
    1100 p.m. with no food to follow.

84
Dose calculation example
  • For example in an 80-kg diabetic requiring 40
    units per day, start with
  • 0800 a.m. --- 10 units regular insulin s/c ½ hr
    before breakfast.
  • 0200 p.m. --- 10 units regular insulin s/c ½ hr
    before lunch.
  • 0800 p.m. --- 10 units regular insulin s/c ½ hr
    before dinner.
  • 1100 p.m. --- 10 units NPH/ lantus insulin s/c

85
Dose adjustment
  • For adjustment of dosage, check fasting blood
    sugar the next day and adjust the dose of night
    time NPH Insulin accordingly i.e. keep on
    increasing the dose of NPH by approximately 2
    units daily until you achieve a normal fasting
    blood glucose level of 80-110 mg/dl.

86
Control BSF by adjusting the prior the dose of
NPH
87
Dose adjustment.contd.
  • Remember that the BSL (Blood Sugar Level) at any
    given time reflects the insulin / meal taken
    before the reading, and therefore, a raised level
    of fasting blood sugar requires a change in the
    dose of previously administered night time
    insulin and will NOT be controlled by adjusting
    the next insulin injection.

88
Dose adjustmentcontd.
  • Once the fasting blood glucose has been
    controlled, check 6-Point blood sugar as follows
  • Fasting.
  • 2 hours after breakfast.
  • Before lunch (and noon insulin)
  • 2 hours after lunch.
  • Before dinner (AND EVENING INSULIN)
  • 2 hours after dinner

89
Control random sugar level by adjusting the prior
dose of regular insulin
90
Dose adjustmentcontd.
  • Now control any raised random reading by
    adjusting the dose of previously administered
    regular insulin.
  • For example a high post lunch reading will NOT
    be controlled by increasing the dose of next
    insulin (as in sliding scale), rather adjustment
    of the pre-lunch regular insulin on the next day
    will bring down raised reading to the required
    levels.

91
Examples
  • We need to increase the dose of NPH at night to
    bring down baseline sugar level (BSF) to around
    100 mg/dl after which the profile should
    automatically adjust as follows
  • Blood sugar fasting 100 mg/dl
  • Blood sugar 02 hrs after breakfast 170 mg/dl
  • Blood sugar pre-lunch 110 mg/dl
  • Blood sugar 2 hrs. after lunch 190 mg/dl
  • Blood sugar pre-dinner 120 mg/dl
  • Blood sugar 2 hrs. post dinner 180 mg/dl
  • For the following profile
  • Blood sugar fasting 180 mg/dl
  • Blood sugar after breakfast 250 mg/dl.
  • Blood sugar pre lunch 190 mg/dl
  • Blood sugar post lunch 270 mg/dl
  • Blood sugar pre dinner 200 mg/dl
  • Blood sugar post dinner 260 mg/dl

92
Examplescontd.
  • Blood sugar fasting 130 mg/dl
  • Blood sugar after breakfast 160 mg/dl
  • Blood sugar pre-lunch 130 mg/dl
  • Blood sugar post lunch 240 mg/dl
  • Blood sugar pre-dinner 180 mg/dl
  • Blood sugar 2 hrs. post dinner 200 mg/dl
  • This patient needs adjustment of pre-lunch
    regular Insulin which will bring down post lunch
    and pre dinner readings within normal limits.
  • 2 hrs post dinner blood sugar(200 mg/dl) will be
    brought down by adjusting pre dinner regular
    insulin.

93
Combinations
  • In types 2 subjects, once the blood sugar profile
    is normalized and the patient is not under any
    stress, the total daily dose (morning noon
    night NPH at 11 p.m) may be divided into two 12
    hourly injections of premixed Insulin

94
Examples.contd.
  • e.g-1 If a patient is stabilized on
  • 10U R 12U R 10U R 12U NPH
  • then he may be shifted to
  • 44/2 22 units of 70/30 Insulin 12 hourly s/c ½
    hr before meal.
  • e.g-2 If the adjusted Insulin is
  • 14U R16U R12U R8U NPH,
  • then split the total dose
  • 30 U 70/30 before breakfast and 20U 70/30
    before dinner to compensate for the high morning
    and lunch Insulin.

95
Combinationscontd.
  • Problem Remember that BD dosing usually fails to
    cover lunch, especially if it is heavy. So
  • Always check for post lunch hyperglycemia when
    using this regimen.
  • Solution
  • Patients can be advised to take their lunch
    (heavier meal) at breakfast and breakfast
    (lighter meal) at lunch.
  • Adding Glucobay with lunch some times provides a
    reasonable control.
  • An alternate combination to overcome the problem
    is regular insulin for morning and noon, with
    premixed insulin at night.

96
Example
  • 10U R before breakfast 12U R before lunch 22U
    70/30 before dinner.
  • Insulin will be injected exactly 6 hrs apart as
    in the QID regimen.

97
Choice of regimens
  • R R R L
  • R R R N
  • R R premixed insulin
  • BD premixed insulins

Adding basal insulin to oral agents is simple to
implement, well tolerated, and highly effective
-- particularly for patients with A1C levels
between 7.0 and 10.0

116
A usual starting dosage for patients with type 2
diabetes is 1 U of rapid-acting insulin for every
10 g of carbohydrate eaten plus an additional 1 U
for every 30 mg/dL above the target
self-monitoring blood glucose level of 100
mg/dL. For example, a patient who had a
premeal self-monitoring blood glucose level of
160 mg/dL, and was planning to eat a meal
containing 30 g of carbohydrate, would take a
prandial insulin dose of 5 U .
117
If the patient is uncomfortable counting
carbohydrates, the physician can recommend a
range of insulin dosages empirically based on the
size of the meal I.e, 5 U of a rapid-acting
analog for a small meal and 8-10 U for a large
meal plus additional units of insulin, if
needed, based on the pre -meal self-monitoring
blood glucose level reading
118
A simple way to introduce prandial insulin is to
start with 1 dose at the main meal (ie, 5-10 U).
119
Titration of regular insulin and analogues
120
You can increase or decrease the dose of regular
insulin and analogues by 20 i.e
If the patients is using, 1-10 units./- 2
unit 11-20 units/- 4 units 21-30
units/- 6units 31-40 units/- 8
units..

How to start pre mixed (70/30) Insulin
122
For pre mixed insulins(70/30 preparations) Step1F
irst calculate the total daily starting
requirement of insulin body weight(kg)/2 eg,
For a 60kg patient,total daily dose 30
units Step 2Then devide this dose into 3 equal
parts 101010 Step 3Give 2 parts in the
morning and 1 part in the evening Morning20U
Evening10 U
123
Dose titration of Pre-mixed(70/30) preparations
124
You can increase or decrease the dose of
pre-mixed insulin by 10 i.e If the patients is
using, 1-10 units./- 1 unit 11-20
units/- 2 units 21-30 units/- 3
units 31-40 units/- 4 units..
125
Advantages and disadvantages of pre- mixed
insulins
126
AdvantagesEasy to administer for the
physician.Easy to fill and inject by the
patient.Provides both basal and bolus coverage
with fewer number of injections.
127
DisadvantageNo dose flexabilityIf u
increase/decrease the dose of one component ,the
dose of other component is also changed un
desirably

How to solve the problem of nocturnal hypoglycemia
133
Somogyi phenomenon
  • Due to
  • excess dose of night time insulin, or
  • Night insulin taken early
  • Peaks at 300 a.m hypoglycemia
  • Counter regulatory hormones released in excess
  • Resulting in over correction of hypoglycemia
  • Fasting hyperglycemia
  • Solution
  • Check BSL AT 3 00 a.m
  • Give long acting at 1100 p.m so peak comes later
  • Reduce dose of night time insulin

135
Dawn phenomenon
  • Growth hormone surge at dawn raises insulin
    requirement.
  • Night time insulin taken early, fades out before
    dawn.
  • Fasting hyperglycemia
  • Solution
  • Give long acting insulin not before 11 00 p.m
  • May need to increase dose of night time insulin

Remember
  • Insulin
  • No miracle drug
  • Has definite indications
  • As delivery route follows reverse physiology
  • Good control is achieved only if residual
    pancreatic function is preserved to a certain
    extent i-e
  • Starting insulin on time is vital
  • (Concept of early insulinization)

143
Pearls for practice
  • Never try to control diabetes with oral
    hypoglycemic drugs / insulin without first
    ensuring strict diet control.
  • Always bring fasting sugar to normal before
    trying to control post prandial / random blood
    sugar.
  • Control any underlying infection/stressful
    condition vigorously.
  • Keep meal timings regular with 6 hrs between the
    three meals.
  • Do not inject NPH before 11 p.m.
  • Keep number of calories during the meals same
    from day to day. The quantity and quality of diet
    should be same at same timings.
  • Do not use sliding scale to calculate the dose of
    insulin.
  • Use proper technique to inject s/c insulin.
  • Ensure proper storage of insulin.

144
Common Problems
145
Problems can be avoided
  • Adherence to time table is all that is required
    to avoid problems
  • Regular meals
  • Regular injections
  • Regular excercise

146
Choosing an Insulin with a
Lower Risk of Hypoglycemia
  • Insulin analogues with longer, non-peaking
    profiles may decrease the risk of hypoglycemia

Injection Techniques
148
Sites of injection
  • Arms ?
  • Legs ?
  • Buttocks ?
  • Abdomen ?

149
Sites of injection.contd.
  • Preferred site of injection is the abdominal wall
    due to
  • Easy access
  • Ample subcutaneous tissue
  • Absorption is not affected by exercise.

150
Injection technique
151
Technique
  • Tight skin fold
  • Spirit. X
  • Appropriate needle size
  • 90 degree angle
  • Change site to avoid lipodystrophy

152
Injection technique.contd.
INSTRUCTIONS Keep the needle perpendicular to
skin in order to avoid variability in absorption
(fig-A) Insert needle upto the hilt
(fig-A) Distribute daily injections over a wide
area to avoid lipodystrophy and other local
complications (fig-B)
153
Storage
  • Injections refrigerate
  • Pens do not refrigerate

154
Shelf life
  • One month once opened
