Granulation has been widely used in the pharmaceutical industry since the 1950s. Whilst the science remains largely identical to that developed over 70 years ago, granulation techniques and equipment have improved to allow for a greater number of applications in both R&D and manufacture. Granulation is a process where primary powder particles are blended and … Read more

Tablets continue to be one of the most popular pharmaceutical dosage forms, as with the right tablet formulation you can achieve: ease of handling and administration for patients, stability convenient packing options, and well-established cost-effective manufacturing processes which produce consistent quality products.

Tablet dosage forms are one of the most popular dosage forms used in the pharmaceutical industry due to their ease of handling and administration for patients, stability, convenient packing options and well-established cost-effective manufacturing processes which produce consistent quality products. However, there are also disadvantages to presenting a drug as a tablet which can include: … Read more

The number of amorphous solid dispersions entering first in human (FIH) studies continues to increase, due to the growing number of novel APIs with a poor solubility profile, and associated bioavailability challenges. Spray drying is a useful technology for creating a form of amorphous solid dispersions called spray dried dispersions (SDDs). Spray drying a poorly … Read more

Currently approximately 9 out of 10 new drugs entering clinical trials will fail before reaching approval. Many of these drugs will fail due to problems with ADME (absorption, distribution, metabolism and excretion) rather than lack of efficacy. One of the more common issues associated with ADME is the need for increasing bioavailability. Therefore, it is … Read more

Pulmonary delivery is showing increased popularity as a viable dosage form for treating local airway diseases and offers additional potential for systemic drug delivery. Within this space there are a number of delivery approaches that can be undertaken. These include dry powder inhaled formulations (DPI) and pressurised metered Dose Inhalers (pMDIs). Each of these delivery … Read more

When customers initiate discussions with Upperton, one of the first questions we are asked is “which spray dryer(s) do you have and how much material can they produce?” Whilst these are very pertinent questions, the answer is not a simple one.
