In the pharmaceutical industry, Oral Rehydration Salts (ORS) are classified as a therapeutic mixture of electrolytes and carbohydrates (usually glucose) used to treat dehydration. As a pharmacist and manufacturer, I view ORS as a “Life-Saving Essential” that serves as a non-invasive alternative to IV fluids for mild to moderate cases of fluid loss.
At your WHO-GMP facility in Mumbai, ORS sachets (typically 20.5g or 4.4g) are a cornerstone of any “Consumer Healthcare” or “Essential Medicines” portfolio for both domestic supply and international export.
Primary Clinical Indications
-
Acute Diarrhea & Gastroenteritis: The most common use, particularly in pediatric care, to replace fluids and salts lost during loose motions.
-
Cholera Management: A critical intervention to manage the rapid and massive fluid loss associated with Vibrio cholerae.
-
Heat Exhaustion: Replaces essential salts (sodium, potassium) lost through excessive sweating in tropical climates like India.
-
Vomiting & Physical Exertion: Rehydrates the body when oral intake of plain water is insufficient to restore the electrolyte balance.
Mechanism: The Sodium-Glucose Co-Transport
ORS works by exploiting a specific “pump” in the small intestine that continues to function even during severe illness.
The SGLT1 Protein: The lining of the small intestine contains the Sodium-Glucose Co-Transporter.
Coupled Absorption: For every molecule of glucose absorbed, one molecule of sodium is pulled with it into the bloodstream.
Osmotic Pull: This concentration of salts and sugar creates an “osmotic gradient,” which pulls water into the body 2 to 3 times faster than plain water alone.
The Pharmacist’s “Technical Warning”
As you build your digital presence, providing these precise instructions is essential for professional authority:
-
Standard Dilution: A standard WHO-formula sachet must be dissolved in exactly 1 liter (or the volume specified on the pack) of clean, boiled, and cooled water.
-
Technical Risk: If the solution is too concentrated (too little water), it can actually draw more water out of the body and into the gut, worsening the diarrhea.
-
-
No Boiling after Mixing: Never boil the solution once the salts are added, as this can break down the glucose and alter the electrolyte balance.
-
24-Hour Rule: Once mixed, the solution must be consumed or discarded within 24 hours to prevent bacterial contamination.
The Manufacturer’s Perspective: Technical & Export
From a production and B2B standpoint at your facility in Mumbai:
-
The “Low Osmolarity” USP: On your marketplace, highlight that you manufacture the WHO Low-Osmolarity ORS (245 mOsm/L). This formula is technically superior as it reduces stool output and the need for IV therapy compared to older, high-salt formulas.
-
Flavor Profiles: While the base formula is salty, offering Orange, Lemon, or Green Apple flavors significantly improves patient compliance, especially in pediatric markets.
-
Stability for Export: Utilizing triple-laminated aluminum sachets is the gold standard for maintaining a 36-month shelf life in Zone IVb tropical regions, preventing clumping and moisture ingress.
