Dosage form for Parkinson's disease, spasticity and muscle spasms

A dosage form for delivering a drug to a drug receptor, wherein the dosage form comprises:

• (a) a wall comprising at least in part a composition permeable to the passage of fluid, which wall surrounds:
• (b) a compartment;
• (c) at least one exit port in the wall that connects the exterior of the dosage form with the compartment;
• (d) a dispensing composition in the compartment comprising a maltodextrin comprising a 500 to 1,000,000 molecular weight and a degree of polymerization of 3 to 6,140;
• (e) 1 mg to 750 mg of drug in the dispensing composition for delivering the drug, by the combined operations of (a) and (b), through the exit port from the dosage form;
• and,
• (f) a push composition in the compartment comprising a hydrogel and an osmotically effective solute, which composition in the presence of fluid that enters the compartment increases in volume and thereby pushes the dispensing composition from the dosage form.
