Abstract

A solid dosage product having a tailored dissolution profile comprises a carrier block defining a plurality of compartments where each respective compartment is configured to receive one or more active pharmaceutical ingredient and the carrier block being digestible within an animal such that each respective active pharmaceutical ingredient is controllably released; and one or more coating layers applied to the carrier block. A method for manufacturing a solid dosage product having a tailored dissolution comprises manufacturing a digestible carrier block where the carrier block defines a plurality of compartments with each respective compartment configured to receive an active pharmaceutical ingredient; filling a respective compartment with a respective active pharmaceutical ingredient; and coating the carrier block with one or more coating layers.

Claims

1. A method for monitoring and calibrating each of a plurality of parallel production units in a global network of production units, each respective production unit manufacturing at least one solid dosage product, the method comprising:

a) manufacturing a calibration model block, the calibration model block being used to establish requirements for an acceptable final dosage form, wherein the acceptable final dosage form includes a first plurality of compartments, wherein at least two compartments of the first plurality of compartments have different dissolution properties;

b) at each respective production unit within the global network;

i) manufacturing a digestible carrier block, the digestible carrier block defining a second plurality of compartments which correspond to the first plurality of compartments, each respective compartment within the second plurality of compartments is configured to receive an active pharmaceutical ingredient;

ii) filling a respective compartment within the second plurality of compartments with a respective active pharmaceutical ingredient;

iii) coating the digestible carrier block with one or more coating layers to form the at least one solid dosage product;

iv) online real-time monitoring using Process Analytical Technology systems of;

a printing head responsible for manufacture of the digestible carrier block, wherein the monitoring includes comparing the dissolution properties of the digestible carrier block with the dissolution properties of the calibration model block,

a first filler head responsible for filling of each respective compartment,

the active pharmaceutical ingredient,

a second filler head responsible for each coating layer, and

each of the one or more coating layers; and

v) transmitting via a wired or wireless network to a central computing location results from the online real-time monitoring to establish online monitoring reports;

c) providing computer-executable instructions at the central computing location for comparing the online monitoring reports from each respective production unit with the established requirements of the acceptable final dosage form to identify non-complying production units; and

d) if needed, modifying each of the non-complying production units to thereby manufacture the at least one solid dosage product satisfying the established requirements for the acceptable final dosage form based in part on the calibration model block.

2. The method of claim 1 further comprising the steps of:

e) validating the at least one solid dosage product and the manufacturing process of step (b) to provide validation data; and

f) documenting, classifying and storing the validation data in a memory at the central computing location.

3. The method of claim 1 wherein the Process Analytical Technology systems include one or more sensors configured to perform one or more of:

Raman spectroscopy;

X-ray;

nuclear magnetic resonance (NMR);

terahertz pulsed imaging;

laser induced breakdown spectroscopy;

acoustic emission (AE);

air-coupled acoustic testing;

contact ultrasonic testing;

photo-acoustics testing including thermomechanical excitation and/or piezoelectric sensing;

near infrared (NIR);

or micro-thermal probing.

4. The method of claim 1 wherein comparing the dissolution properties of the digestible carrier block with the dissolution properties of the calibration model block includes use of one or more of:

cluster analysis, supervised machine learning, a neural network, genetic algorithms, principal component analysis, decision trees, or Bayesian statistics.
