Asthma
Asthma

  • Most common chronic illness of childhood, affecting approximately 10% children.

  • Available preventive therapies for persistent asthma include inhaled

    delivery system containing corticosteroids and long acting beta agonists.

  • Adherence with inhaled therapies is poor in pediatrics.

  • Orally active leukotriene receptor antagonists are shown to be effective in pediatric patients.


Montelukast sodium
Montelukast sodium

  • Indications: Prophylaxis and treatment of asthma, exercise induced asthma, in Aspirin sensitive asthamatics.

  • Potent, selective and orally acting leukotriene receptor antagonist.

  • Acts by inhibiting physiological actions of LTC4, LTD4 and LTE4 at the Cystiene Leukotriene levels (Cys LT1 receptor).

  • Dose: Adults :- 10 mg OD Child 6-14 yrs:- 5 mg OD 2-5 yrs :- 4 mg OD

  • Rapid oral absorption with mean oral bioavailability of 64 %.


Objective of incevtigation
Objective of incevtigation

  • Formulation palatable mouth dissolve tablets of Montelukast Sodium.

  • Evaluate the efficacy of Ion exchange resin (Indion 414) as superdisintegrant over the extsting ones in mouth dissolve tablets.


Melt in mouth tablets
Melt in Mouth Tablets

These are solid dosage forms that dissolve or disintegrate within a

Minute in the oral cavity without the need of water or chewing and have a pleasant taste.

Advantages offered

  • Ease of swallowing

  • Ease of handling

  • Improved patient compliance

  • Line extension and lifecycle management.


Ion exchange resins
Ion Exchange Resins

  • Safe for oral consumption.

  • Indion 414 is a water insoluble, chemically crosslinked acrylic copolymer matrix with carboxylic acid as functional group (Potassium form).

  • Swelling property of ion exchange resins makes them ideal candidate as superdisintegrants.

UV Spectrophotometric method for analysis of Montelukast Sodium

Detection lmax 342 nm

Linearity range 10-50 mg/ml

Slope ± SD 0.0194 ± 0.0014

Regression coefficient 0.999


Formulation development
Formulation Development

  • Montelukast Sodium was mixed in geometric proportions with superdisintegrants, sweetners, diluent, flavors and lubricants. Various concentrations of superdisintegrants were employed to arrive at an optimum disintegration time.

  • Blend was screened through 40 #.

  • Compressed on Cadmach single station tablet press machine equipped with 9 mm flat beveled punches.

Conclusion
Conclusion Sodium

  • Patient compliant and palatable melt in mouth tablets of Montelukast Sodium having optimum physicochemical properties were formulated.

  • Ion exchange resin (Indion 414) could be successfully used as superdisintegrant, thus making the formulation cost effective.

  • The tablets exhibited an in-vitro disintegration time of 20 seconds.

  • The technology can also be easily employed for large-scale manufacturing.
