Tromethamine

Aka: Tromethamine, THAM
  1. Indications
    1. Severe Metabolic Acidosis from Cardiac Arrest (alternative to Sodium Bicarbonate)
  2. Mechanism
    1. Weak base binds Hydrogen Ions and excreted renally
  3. Effects
    1. Unlike Sodium Bicarbonate which relies on CO2 exhalation to correct Metabolic Acidosis, THAM is renally excreted
      1. THAM may be preferred over Sodium Bicarbonate in the non-ventilated patient with Respiratory Acidosis
    2. Unlike Sodium Bicarbonate which lowers Serum Potassium, THAM does not alter Potassium levels
    3. Unlike Sodium Bicarbonate which increases Serum Sodium, THAM lowers Serum Sodium
  4. Dosing
    1. Dose = wtKg x baseDeficit x 1.1
  5. Precautions
    1. Avoid acidosis over-correction
  6. Efficacy
    1. As with Sodium Bicarbonate, no evidence of outcome benefit in correction of Metabolic Acidosis
  7. Adverse effects
    1. Slowed Respiratory Rate
    2. Hypoglycemia

Tromethamine (C0041175)

Definition (NCI) A member of the pyrrolo-pyrrole group of non-steroidal anti-inflammatory drugs (NSAID) with analgesic, anti-inflammatory, and anti-pyretic properties. Tromethamine inhibits both isoforms of cyclooxygenases (COX1 and COX2), thereby blocking the conversion of arachidonic acid to pro-inflammatory pro-prostaglandins. When inhibiting COX2, tromethamine may be effective in relieving pain and inflammation; when inhibiting COX1, this agent may produce unacceptable gastrointestinal side effects.
Definition (MSH) An organic amine proton acceptor. It is used in the synthesis of surface-active agents and pharmaceuticals; as an emulsifying agent for cosmetic creams and lotions, mineral oil and paraffin wax emulsions, as a biological buffer, and used as an alkalizer.
