The brand name Totilac refers to different medical products with distinct applications. The most prominent medical use, particularly in critical care, involves a hypertonic sodium lactate (HSL) solution administered intravenously for conditions like traumatic brain injury and post-cardiac surgery complications. Concurrently, another product under the TOTILAC brand name is an over-the-counter lactase enzyme supplement used to manage lactose intolerance. This diversity in application, coupled with potential confusion with other medications like lactulose, underscores the importance of correctly identifying the specific Totilac product and its intended purpose. Patients and clinicians must carefully distinguish between these formulations to ensure appropriate treatment.
Totilac as a Hypertonic Lactate Solution in Critical Care
In specialized clinical settings, Totilac is used as an intravenous hypertonic lactate solution. Its active components are hypertonic sodium lactate, potassium chloride, and calcium chloride. This unique formulation offers two key therapeutic benefits for critically ill patients:
- Intracranial Pressure (ICP) Management: In cases of traumatic brain injury (TBI) and other conditions causing increased intracranial pressure, the hyperosmolar nature of Totilac draws excess fluid from the brain tissue into the bloodstream. This fluid shift helps to reduce brain swelling and lower ICP. Studies have shown that it can be more effective than other hyperosmolar agents, such as mannitol, in achieving a prolonged decrease in ICP.
- Energy Substrate for Ischemic Tissues: The lactate content in Totilac provides an alternative energy source for cells in a state of ischemia (inadequate blood supply). During hypoxic periods, lactate can be actively oxidized by the brain, heart, and other organs to release energy, supporting cell function where glucose metabolism may be impaired.
Clinical Applications of Hypertonic Lactate
The hypertonic lactate solution has specific indications for use, primarily in emergency and post-operative care:
- Traumatic Brain Injury (TBI): It is used as a neuroprotective fluid to manage intracranial hypertension. By reducing ICP and providing an energy source for the injured brain, it helps prevent secondary brain injury.
- Cardiac Surgery Resuscitation: Following complex procedures like coronary artery bypass grafting (CABG), Totilac infusion has shown superior efficacy compared to standard Ringer's Lactate solution. It improves the cardiac index, indicating better heart performance, and requires a smaller total fluid volume for effective resuscitation.
- Fluid Resuscitation: In hemorrhagic shock, dengue shock, and other conditions requiring rapid restoration of intravascular volume, its hypertonic properties are beneficial. It helps improve hemodynamics by drawing fluid into the intravascular space, thus maintaining stable blood pressure.
Totilac as a Lactase Enzyme Supplement
Separate from its critical care application, the brand TOTILAC is also used for a lactase enzyme supplement. This product, often available in tablet form, is used by individuals with lactose intolerance.
- Mechanism of Action: The lactase enzyme in the supplement breaks down lactose, a sugar found in dairy products, into simpler, more digestible sugars like glucose and galactose. This prevents the undigested lactose from causing gastrointestinal symptoms.
- Clinical Use: Patients with lactose intolerance take the supplement orally right before consuming dairy-containing foods. This helps to reduce common symptoms such as abdominal pain, bloating, gas, and diarrhea. The dosage can be adjusted based on the amount of dairy consumed and the individual's degree of intolerance.
The Confusion: Totilac vs. Lactulose
Some online resources may incorrectly refer to a medication for constipation or hepatic encephalopathy as "Totilac". This is a common source of confusion. The medication used for these purposes is actually lactulose, a synthetic sugar that functions as an osmotic laxative.
- Lactulose for Constipation: It draws water into the colon to soften stools and promote bowel movements.
- Lactulose for Hepatic Encephalopathy: It reduces blood ammonia levels by facilitating its removal from the body through stool.
- Distinguishing the Products: The intravenous hypertonic lactate solution (Totilac) and the laxative lactulose are entirely different drugs used for unrelated conditions. The misassociation is likely due to the similar-sounding names and the presence of "lactate" in one product's name and the "lac" suffix in the other.
Comparison of Hypertonic Lactate and Mannitol for Intracranial Pressure
When managing increased ICP, medical professionals may choose between several hyperosmolar agents, primarily hypertonic sodium lactate (Totilac) and mannitol. While both are effective, they have different properties that may influence the choice of treatment.
| Feature | Hypertonic Sodium Lactate (Totilac) | Mannitol |
|---|---|---|
| Mechanism of ICP Reduction | Increases intravascular osmotic pressure, drawing fluid out of the brain parenchyma. | Increases intravascular tonicity, pulling water out of the brain parenchyma. |
| Additional Benefit | Provides an energy substrate (lactate) for the ischemic brain and heart. | Can improve cerebral blood flow by reducing blood viscosity. |
| Hemodynamic Effects | Considered superior in maintaining intravascular volume, improving cardiac output with less fluid volume. | May cause hypotension due to its diuretic effect, making it less ideal for hemodynamically unstable patients. |
| Electrolyte Balance | Prevents hyperchloremic acidosis. | Can cause electrolyte disturbances, including hyponatremia. |
| Potential Side Effects | Hypernatremia (high sodium), metabolic alkalosis. | Dehydration, electrolyte imbalances, and renal dysfunction with prolonged use. |
Conclusion
The question “What is the use of Totilac?” does not have a single, straightforward answer due to the existence of multiple products bearing the same or similar brand name. The most significant medical application is the intravenous hypertonic lactate solution (Totilac), used as a resuscitative fluid and intracranial pressure reducer in critical care settings, including cases of traumatic brain injury and post-cardiac surgery. Its dual function as an osmotic agent and an energy source provides specific advantages over alternative treatments like mannitol. Separately, an oral TOTILAC supplement exists for managing lactose intolerance by providing the lactase enzyme. It is crucial for healthcare providers and patients to be aware of these different products to prevent confusion and ensure safe and effective treatment. Always consult a healthcare professional for guidance regarding the appropriate medication for a specific condition.
