QuilliChew Active Ingredient

QuilliChew contains methylphenidate hydrochloride as its active ingredient 1.

Formulation Details

QuilliChew ER (methylphenidate hydrochloride extended-release chewable tablets) is a CNS stimulant formulation designed specifically for ADHD treatment 1. The product has several distinctive characteristics:

Composition

  • Only 15% of methylphenidate is present as methylphenidate hydrochloride salt
  • The remaining 85% exists as methylphenidate ionically-bound to sodium polystyrene sulfonate particles 1
  • The formulation contains approximately 30% immediate-release and 70% extended-release methylphenidate 1

Available Strengths

QuilliChew ER comes in three dosage strengths: 20 mg, 30 mg, and 40 mg 1. All dosage strengths are expressed in terms of methylphenidate hydrochloride equivalents.

Key Formulation Features

The chewable tablet is cherry-flavored and uses ion exchange technology to achieve its extended-release properties 1, 2, 3. This formulation was developed to improve adherence in patients who have difficulty swallowing tablets or capsules, while maintaining once-daily dosing convenience 2, 3.

Mechanism of Action

Methylphenidate blocks the reuptake of norepinephrine and dopamine into the presynaptic neuron and increases the release of these monoamines into the extraneuronal space 1. The d-isomer is more pharmacologically active than the l-isomer 1.
