Prescription for Diabetic Patient Using Pakistani Brand Medications by Blood Sugar Level

For adult diabetic patients in Pakistan, metformin remains the first-line medication regardless of blood sugar level, with treatment intensification based on glycemic control using sulfonylureas, then insulin, following a stepwise approach 1, 2.

Treatment Algorithm by Blood Sugar Reading (BSR)

Mild Hyperglycemia (Fasting: 140-200 mg/dL / Random: 180-250 mg/dL)

First-Line:

  • Tab. Glucophage (Metformin) 500mg - Start once daily with largest meal
  • Titrate to 500mg twice daily after 1 week, then 500mg three times daily (or 1000mg twice daily) based on tolerance 1

If inadequate control after 3 months (HbA1c >7%):

  • Add Tab. Amaryl (Glimepiride) 1-2mg once daily before breakfast OR
  • Add Tab. Diamicron MR (Gliclazide Modified Release) 30-60mg once daily before breakfast 2, 3

Moderate Hyperglycemia (Fasting: 200-300 mg/dL / Random: 250-350 mg/dL)

Dual Therapy from Start:

  • Tab. Glucophage (Metformin) 500mg twice daily with meals
  • PLUS Tab. Amaryl (Glimepiride) 2mg once daily before breakfast OR
  • Tab. Diamicron MR (Gliclazide) 60mg once daily before breakfast 1, 2

Alternative if sulfonylurea contraindicated:

  • Tab. Januvia (Sitagliptin) 100mg once daily (reduce to 50mg if eGFR 30-45 mL/min) 1, 4
  • Note: Sitagliptin/Metformin combination is most commonly prescribed in Pakistan 4

Severe Hyperglycemia (Fasting: >300 mg/dL / Random: >350 mg/dL)

Insulin Initiation Required:

Basal Insulin Regimen:

  • Inj. Insulatard (NPH Insulin) - Start 0.2-0.3 units/kg once daily at bedtime
  • OR Inj. Lantus (Insulin Glargine) - 0.2-0.3 units/kg once daily (preferred for lower hypoglycemia risk) 5, 2, 6

Continue:

  • Tab. Glucophage (Metformin) 500mg-1000mg twice daily (unless contraindicated) 1, 2

Titration: Increase basal insulin by 2 units every 3 days until fasting glucose 90-130 mg/dL 5, 6

Very Poor Control or Symptomatic (Any BSR with HbA1c >10% or symptoms)

Basal-Bolus Insulin Regimen:

Calculate total daily dose: 0.4-0.5 units/kg body weight 5, 6

  • 50% as basal insulin
  • 50% divided as prandial insulin (before each meal)

Example for 70kg patient:

  • Total daily dose: 28-35 units
  • Inj. Insulatard (NPH) 14-17 units at bedtime OR Inj. Lantus 14-17 units once daily
  • Inj. Actrapid (Regular Insulin) 5-6 units before each main meal 5, 6

Alternative Premixed Option (simpler but less flexible):

  • Inj. Mixtard 30/70 - Give usual morning dose at dinner, half the evening dose at pre-dawn meal 3

Supplemental (Correction) Insulin Scale

For patients on insulin, add correction doses based on pre-meal readings 5:

Blood Sugar (mg/dL) Inj. Actrapid (Regular Insulin)
141-180 2 units
181-220 4 units
221-260 6 units
261-300 8 units
301-350 10 units
>350 12 units + call physician

Critical Prescribing Considerations for Pakistani Context

Medication Availability Issues:

  • Newer agents (SGLT2 inhibitors, GLP-1 agonists) have limited availability and high cost in Pakistan 7, 8
  • Human insulin (Actrapid, Insulatard) more affordable than analogs but insulin prices increased 31.87% post-deregulation 8
  • Generic metformin widely available and cost-effective 4

Common Pitfalls to Avoid:

  • Never use sliding scale insulin alone - associated with poor control and 3-fold increased hyperglycemia risk 5, 6
  • Avoid premixed insulin in hospital settings - unacceptably high hypoglycemia rates 6
  • Reduce insulin dose by 20% if patient has poor oral intake or age >70 years 5, 9
  • Hold metformin during acute illness, dehydration, or renal impairment (eGFR <30) 1, 9

Dose Adjustments for Special Populations:

  • Elderly (>70 years): Start insulin at 0.2 units/kg; use lower sulfonylurea doses 5, 9
  • Renal impairment (eGFR <60): Reduce insulin to 0.2-0.3 units/kg; avoid glyburide; adjust DPP-4 inhibitors 1, 9
  • Ramadan fasting: Switch sulfonylurea dose to evening (Iftar), reduce morning dose by 50% 3

Monitoring Requirements:

  • Check fasting glucose weekly during titration
  • HbA1c every 3 months
  • Adjust doses if >50% of readings outside target over 1 week 5, 9

Cost Considerations:

  • Average prescription cost in Pakistan: PKR 3,404 (~$12.6 USD) 4
  • Metformin most cost-effective; insulin and combinations most expensive 4, 8
  • 2.51 days' wages needed for lowest-paid worker to afford one month of insulin 8

This prescription framework prioritizes medications available in Pakistan while following international guidelines, with specific attention to the high diabetes prevalence (9.6%) and economic constraints in the Pakistani healthcare system 10, 7.
