Why Topical Formulation Development is Important in the Drug Manufacturing

Posted by TergusPharma on May 14th, 2021

When it comes to topical formulation, it has become highly important nowadays for the pharmaceutical industry. If we talk about topical delivery, it comes with numerous advantages that are mentioned following. 

• It includes a vast capability for delivering drug substances in a selective way to some particular sites.
• It improves compliance
• It includes intra and inter-patient variation
• It prevents drug level fluctuation
• It is appropriate for self-medication
• It improves sustainability for self-medication

As far as topical therapies’ benefits are concerned, these are something that generally relies on getting the best formulation. Even small topical formulation changes have a bigger difference in terms of the effectiveness of treatment in topical CDMO.

Moreover, the formulation indeed keeps a great importance for topical therapies. It keeps the same relevance as molecule since the vehicle interaction with the skin tends to impact penetrant efficacy. Apart from this, the formulation also works effectively when it comes to ensuring that drug substance gets delivered to those of the targeted sites, and also it is capable of maintaining those of dosage integrity, active duration, and also transportation of drug.

A perfect topical formulation development should include a pre-formulation analysis and study, skin penetration studies, cell line, IVRT, permeation enhancers, stabilizers, etc. The perfect selection of excipients or drugs is something that matters a lot and one should spend enough time for the same.

It goes without saying that drug substance is efficacious, but it can alter numerous things by interacting with excipients. 

• Its potential to permeate via skin
• Its capability of not metabolizing in skin
• Its ability to be stable with the help of shelf life
• Dissolving ability at defined concentrations
• Its ability to get the preferred release rates
