Acetylcysteine is a derivative of the amino acid, cysteine. Mucomist® DT contains Acetylcysteine 600 mg. Mucomist® DT (dispersible tablet) is a new pharmaceutical form that ensures optimum stability, rapid dissolution, maximal absorption, high bioavailability in a perfectly calibrated dosage. Mucomist® Respirator Solution contains 20% or 200 mg/ml Acetylcysteine and available as sterile, unpreserved solution (not for injection). The 20% inhalation solution is given by nebulization or by instillation intratracheally.
Mucomist DT Dispersible Tablets
The dispersible tablet should be dissolved in 1/2 glass of water before use (preferably in the evening). The duration of treatment should be 5 to 10 days in the acute phase. It may be continued in the chronic state for up to 6 months or according to the advice of the physician.
As a mucolytic:
Adults: 600 mg daily as a single dose.
In Paracetamol overdose: Initially 140 mg/kg, followed by 70 mg/kg every 4 hours for an additional 17 doses. As an antidote, Acetylcysteine is reported to be very effective when administered within 8 hours of Paracetamol overdose, with the protective effect diminishing after this time. Initiation of treatment after a lapse of 15 hours has previously been thought to be ineffective, but recent studies suggest that beneficial results may still be obtained.
Acetylcysteine Respirator Solution:
The 20% solution may be diluted to a lesser concentration with either Sodium Chloride for injection, Sodium Chloride for inhalation, sterile water for injection, or sterile water for inhalation.
As a mucolytic:
5-10 ml of 10% or 20% solution by nebulizer every 6-8 hr PRN.
1-11 months: 1-2 ml of 20% or 2-4 ml of 10% solution by nebulizer every 6-8 hr PRN.
12 months-11 years: 3-5 ml of 20% or 6-10 ml of 10% solution by nebulizer every 6-8 hr PRN.
Below 12 years: 5-10 ml of 10/20% solution by nebulizer every 6-8 hr PRN.
Diagnostic Bronchograms: 1-2 ml of 20% or 2-4 ml of 10% solution 2-3 times by nebulization or by instillation intratracheally prior to procedure.
Nebulization tent or croupette: This form of administration requires very large volumes of the solution, occasionally as much as 300 ml during a single treatment period. If a tent or croupette must be used, the recommended dose is the volume of acetylcysteine (using 20%) that will maintain a very heavy mist in the tent or croupette for the desired period. Administration for intermittent or continuous prolonged periods, including overnight, may be desirable.
Direct Instillation: When used by direct instillation, 1-2 ml of a 20% solution may be given as often as every hour. When used for the routine nursing care of patients with tracheostomy, 1-2 ml of a 20% solution may be given every 1-4 hours by instillation into the tracheostomy.
