Nasal delivery overview Drug administration via the nasal route can be used as an efficient method of administration for both local and systemic acting drugs. The nasal route offers a range of advantages including its relative ease of use as compared to injectable administration, patient acceptability and compliance. It also provides a suitable route for … Read more
By 2020, 58% of all therapeutics in development are injectable, 29% oral and 4% inhaled including nasal delivery, and while nasal delivery may not be one of the most explored routes, it has the potential to offer an alternative delivery method for therapeutics with some specific advantages. Nasal delivery of drugs has traditionally been via … Read more
With the continued expansion of our tablet formulation development services, Upperton currently have a number of tablet dosage form development projects completed or in progress. Theses tablet / solid dosage form projects have encompassed a wide range of development activities from Active Pharmaceutical Ingredient (API) characterisation and feasibility studies through the application of enabling technologies, … Read more
Stages of Tablet Compression Equipment Used During Formulation and Process Development Tablets are one of the most popular dosage forms used in the pharmaceutical, nutraceutical and veterinary industries due to their ease of handling and administration, stability, convenient packing options and well-established cost-effective manufacturing processes which produce consistent quality products. Developing a tablet formulation from … Read more
In this article, Upperton interviewed Dr Ian Lafferty, our Chief Technical Officer on the topic of developing spray dried dispersions (SDDs) into tablets. Ian has 25 years of technical and operational experience in early-phase pharmaceutical development encompassing the formulation design, development, process optimisation and manufacture of a wide range of dosage forms including oral solids … Read more
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. However, there are also disadvantages which can include: poor bioavailability, instability within the … 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
