Acetylcysteine + Pyridoxamine dihydrochloride + Taurine

Usage

This combination is primarily prescribed as a nutritional supplement to support kidney health and manage diabetic nephropathy. It also exhibits antioxidant properties and offers cellular health, liver function, and immune system support.

• Pharmacological Classification: Antioxidant, Nephroprotective Agent.

• Mechanism of Action: Acetylcysteine and taurine act as antioxidants, scavenging free radicals and reducing oxidative stress, thus mitigating kidney damage. Pyridoxamine dihydrochloride, a form of vitamin B6, helps maintain energy balance. This combined action slows the progression of diabetic nephropathy and improves kidney function.

Alternate Names

• Renosave Forte
• Thiamin R Tablet (combined with other ingredients)
• Renopal
• Nefrosave
• Styletaurine

How It Works

• Pharmacodynamics: Acetylcysteine and taurine exert antioxidant effects by scavenging free radicals and protecting kidney cells from oxidative damage. Pyridoxamine enhances energy balance, supporting overall metabolic function.

• Pharmacokinetics: Acetylcysteine is readily absorbed orally. Taurine is also well-absorbed and distributed throughout the body. Pyridoxamine converts to pyridoxal phosphate, the active form of vitamin B6. Elimination is primarily renal.

• Mode of Action: The combination works by reducing oxidative stress and improving kidney function.

• Receptor Binding, Enzyme Inhibition, or Neurotransmitter Modulation: Taurine modulates certain brain receptors and can enhance insulin action.

Dosage

Standard Dosage

Adults:

One tablet containing Acetylcysteine 150mg + Pyridoxamine Dihydrochloride 75mg + Taurine 500mg once or twice daily, after meals. Other dosages of Acetylcysteine (300mg, 600mg, 1200mg) are available and can be adjusted according to medical condition.

Children:

This combination is not recommended for children under 18 years of age.

Special Cases:

• Elderly Patients: Dosage adjustments may be necessary based on renal function.
• Patients with Renal Impairment: Dosage reduction may be required.
• Patients with Hepatic Dysfunction: Caution is advised, and dosage adjustments may be necessary.
• Patients with Comorbid Conditions: Use with caution in patients with asthma, COPD, or stomach ulcers. Careful blood sugar monitoring is essential for diabetic patients.

Clinical Use Cases

Specific dosage recommendations for clinical settings such as intubation, surgical procedures, mechanical ventilation, ICU use, and emergency situations are not explicitly defined for this combination. Dosage is generally determined by the underlying condition (diabetic nephropathy, paracetamol poisoning, etc.) as directed by a physician. For instance, for paracetamol poisoning, a loading dose of 140 mg/kg, followed by maintenance doses of 70 mg/kg every 4 hours for a total of 17 doses might be used. For radiocontrast-induced nephropathy, 600-1200 mg/day for 2 days is sometimes recommended. Acetylcysteine can also be used as a mucolytic, where the dosage is three times a day.

Dosage Adjustments

Dosages should be adjusted for renal or hepatic impairment as per medical advice.
