Dosage of Mecomin in details

infoThe dose of a drug and dosage of the drug are two different terminologies. Dose is defined as the quantity or amount of medicine given by the doctor or taken by the patient at a given period. Dosage is the regimen prescribed by the doctor about how many days and how many times per day the drug is to be taken in specified dose by the patient. The dose is expressed in mg for tablets or gm, micro gm sometimes, ml for syrups or drops for kids syrups. The dose is not fixed for a drug for all conditions, and it changes according to the condition or a disease. It also changes on the age of the patient.


Mecomin, like other long-acting neuromuscular blocking agents, displays variability in the duration of its effect. The potential for a prolonged clinical duration of neuromuscular block must be considered when Mecomin is selected for administration. The dosage information provided below is intended as a guide only. Doses should be individualized. Factors that may warrant dosage adjustment include: advancing age, the presence of kidney or liver disease, or obesity (patients weighing ≥ 30% more than ideal body weight for height). The use of a peripheral nerve stimulator will permit the most advantageous use of Mecomin, minimize the possibility of overdosage or underdosage, and assist in the evaluation of recovery.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.


Initial Doses

When administered as a component of a thiopental/narcotic induction-intubation paradigm as well as for production of long-duration neuromuscular block during surgery, 0.05 mg/kg (2 × ED95) Mecomin produces good-to-excellent conditions for tracheal intubation in 5 minutes in approximately 90% of patients. Lower doses of Mecomin may result in a longer time for development of satisfactory intubation conditions. Clinically effective neuromuscular block may be expected to last approximately 100 minutes on average (range: 39 to 232) following 0.05 mg/kg Mecomin administered to patients receiving balanced anesthesia.

An initial Mecomin dose of 0.08 mg/kg (3 × ED95) should be reserved for instances in which a need for very prolonged neuromuscular block is anticipated. In approximately 90% of patients, good-to-excellent intubation conditions may be expected in 4 minutes after this dose; however, clinically effective block may be expected to persist for as long as 160 minutes or more (range: 110 to 338).

If Mecomin is administered during steady-state isoflurane, enflurane, or halothane anesthesia, reduction of the dose of Mecomin by one third should be considered.

When succinylcholine is administered to facilitate tracheal intubation in patients receiving balanced anesthesia, an initial dose of 0.025 mg/kg (ED95) Mecomin provides about 60 minutes (range: 9 to 145) of clinically effective neuromuscular block for surgery. For a longer duration of action, a larger initial dose may be administered.

Maintenance Doses

Maintenance dosing will generally be required about 60 minutes after an initial dose of 0.025 mg/kg Mecomin or 100 minutes after an initial dose of 0.05 mg/kg Mecomin during balanced anesthesia. Repeated maintenance doses administered at 25% T1 recovery may be expected to be required at relatively regular intervals in each patient. The interval may vary considerably between patients. Maintenance doses of 0.005 and 0.01 mg/kg Mecomin each provide an average 30 minutes (range: 9 to 57) and 45 minutes (range: 14 to 108), respectively, of additional clinically effective neuromuscular block. For shorter or longer desired durations, smaller or larger maintenance doses may be administered.


When administered during halothane anesthesia, an initial dose of 0.03 mg/kg (ED95) produces maximum neuromuscular block in about 7 minutes (range: 5 to 11) and clinically effective block for an average of 30 minutes (range: 12 to 54). Under halothane anesthesia, 0.05 mg/kg produces maximum block in about 4 minutes (range: 2 to 10) and clinically effective block for 45 minutes (range: 30 to 80). Maintenance doses are generally required more frequently in children than in adults. Because of the potentiating effect of halothane seen in adults, a higher dose of Mecomin may be required in children receiving balanced anesthesia than in children receiving halothane anesthesia to achieve a comparable onset and duration of neuromuscular block. Mecomin has not been studied in pediatric patients below the age of 2 years.


Y-site Administration

Mecomin Injection may not be compatible with alkaline solutions with a pH greater than 8.5 (e.g., barbiturate solutions).

Mecomin is compatible with:

  • 5% Dextrose Injection, USP
  • 0.9% Sodium Chloride Injection, USP
  • 5% Dextrose and 0.9% Sodium Chloride Injection, USP
  • Lactated Ringer's Injection, USP
  • 5% Dextrose and Lactated Ringer's Injection
  • Sufenta® (sufentanil citrate) Injection, diluted as directed
  • Alfenta® (alfentanil hydrochloride) Injection, diluted as directed
  • Sublimaze® (fentanyl citrate) Injection, diluted as directed
Dilution Stability

Mecomin diluted up to 1:10 in 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP has been shown to be physically and chemically stable when stored in polypropylene syringes at 5° to 25°C (41° to 77°F), for up to 24 hours. Since dilution diminishes the preservative effectiveness of benzyl alcohol, aseptic techniques should be used to prepare the diluted product. Immediate use of the diluted product is preferred, and any unused portion of diluted Mecomin should be discarded after 8 hours.

What other drugs will affect Mecomin?

Tell your doctor about all your other medicines, especially:

  • chloramphenicol;

  • oral diabetes medicine that contains metformin; or

  • medicines that reduce stomach acid, such as cimetidine, omeprazole, lansoprazole, Nexium, Prevacid, Prilosec, Zantac, and others.

This list is not complete. Other drugs may affect Mecomin, including prescription and over-the-counter medicines, vitamins, and herbal products. Not all possible drug interactions are listed here.

Drug Interactions (in more detail)

Mecomin interactions

infoInteractions are the effects that happen when the drug is taken along with the food or when taken with other medications. Suppose if you are taking a drug Mecomin, it may have interactions with specific foods and specific medications. It will not interact with all foods and medications. The interactions vary from drug to drug. You need to be aware of interactions of the medicine you take. Most medications may interact with alcohol, tobacco, so be cautious.

Antibiotics: The use of antibiotics may alter the intestinal microflora and may decrease the possible contribution of Mecomin by certain inhabitants of the microflora (eg, Lactobacillus spp) to the body's requirement for the vitamin. This may particularly be a problem for vegetarians. Garlic, onions, leeks, bananas, asparagus and artichokes, among other vegetables and fruits, contain inulins which promote the growth of certain colonic bacteria including Lactobacillus spp.

Cholestyramine: Cholestyramine may decrease the enterohepatic reabsorption of Mecomin.

Colchicine: Colchicine may cause decreased absorption of Mecomin.

Colestipol: Colestipol may decrease the enterohepatic reabsorption of Mecomin.

H2-Blockers (Cimetidine, Famotidine, Nizatidine, Ranitidine): Chronic use of H2-blockers may result to decreased absorption of Mecomin. They are unlikely to affect the absorption of supplemental B12.

Metformin: Metformin may decrease the absorption of Mecomin. This possible effect may be reversed with oral calcium supplementation.

Nitrous Oxide: Inhalation of the anesthetic agent nitrous oxide (not to be confused with nitric oxide) can produce a functional deficiency. Nitrous oxide forms a complex with cobalt in Mecomin, the cofactor for methionine synthase, resulting in inactivation of the enzyme.

Para-Amino Salicylic Acid: Chronic use of the anti-tuberculosis drug may decrease the absorption of Mecomin.

Potassium Chloride: It has been reported that potassium chloride may decrease the absorption of Mecomin.

Proton Pump Inhibitors (Lansoprazole, Omeprazole, Pantoprazole, Rabeprazole): Chronic use of proton pump inhibitors may result in decreased absorption, naturally found in food sources.
