Rheology methods for the formulation development of tablets

At Caleva we are known for our expertise in helping our customers in the pharmaceutical industry with extrusion, spheronization, and making pellets.

But we can also help with tabletting projects !

The Caleva Mixer Torque Rheometer (MTR) is widely used to measure the characteristics of a wet granulation to establish the correct endpoint and mix time for any given formulation.

The experiments and methods used by the MTR can also be applied to formulation development of tablets.

The process still involves the mixing of a wet granulation but with less liquid binder than the extrusion and spheronization process requires.

We all know R&D takes time and precious materials, but ask yourself how much of these expensive resources you could save by doing simple and fast experiments to establish your optimum binder addition and mix time, in small batches of 5 g to 50 g.

Changeover between experiments can be achieved very quickly!  Some of our customers have characterised up to 15 different formulations in a single day using the Mixer Torque Rheometer.

The ability to physically measure these characteristics gives you real data to work with, with an outcome of consistent, provable, and recorded data to fast track your tablet formulation development.

Opportunities for Mixer Torque Rheometry

Wet granulations are a useful precursor to many solid dosage formulations and as such are widely used in the pharmaceutical industry. Because of the diverse nature of pharmaceutical materials, granulation is often employed as an intermediate process to enhance flow and compaction properties and impr... Read More

How much product should be used in the MTR and how accurate is it?

How much product do you use?  The answer is that this is always product specific. This is demonstrated in this article.  In these experiments the MTR is used in the multiple addition mode whereby increasing binder content is automatically added to different masses of product.  The Caleva Mixer Torqu...

Can temperature during granulation influence formulation consistency?

The temperature of the mix during granulation processes is generally considered to be of minor significance in both formulation development and in large batch granulation despite the fact that in some locations ambient temperature can change significantly during the course of a working day. The MTR ... Read More

A Tool For Preformulation Assessment Of Excipients

  Excipients from different batches or vendors may be variable in quality and it is often necessary to perform pre-formulation assessment for each batch of excipient received. In some cases, excipients from different vendors require comparative assessment of their equivalent functionality. In this t... Read More

How long should I granulate my materials?

Variable Mix Time Test It is well-known that a minimum amount of mixing is required to ensure consistent and repeatable product characteristics. What is often less considered is the possibility of over-mixing the product so that the characteristics of the resulting formulation undergo a change. Read More

How do I ensure consistency during scale up?

Consistency Measurement A direct consistency measurement of a small sample (generally around 40 g) taken from a process as it is ongoing.  This allows for accurate comparisons to be made quickly, accurately, and repeatable way. Read More

Formulation development - determine optimum powder to binder ratio

Multiple Addition Test Binder liquid is added to a dry powder mix and the consistency is measured as the mixing and addition of binder progresses. The consistency of the mix is measured at regular periods so that the relationship between the amount of liquid binder added to the mix and the consisten... Read More

What characteristics should my extrudate have?

Extrusion and spheronization is not always completely straightforward.  A formulation required for spheronization needs to go through the following processes and achieve the following properties. Read More

How to produce consistent formulations from different mixers

Customer Quote: Mr. K.S (Aurobindo) "It is exciting to see the correlation between the two graphs and granulation end point".  With a major pharmaceutical manufacturer, together we characterised all their various mixers to produce a consistent formulation. To identify three important characteristics... Read More

Do excipients purchased from different vendors behave in the same way?

The Mixer Torque Rheometer can be used to assess the behaviour of excipients purchased from different suppliers. Background Excipients from different batches or vendors may be variable in quality and it is often necessary to perform pre-formulation assessment for each batch of excipient received.  I...
