Pain and discomfort on injection, Electromyogram assessment of pain or discomfort in muscles, effect of formulation and device variables on discomfort

Parenteral drug delivery is one of the most widely available methods of drug delivery. However, needle-related procedures in parenteral drug delivery are a common source of pain and distress in humans, which in turn may limit patient compliance. Concerns on pain are related to needle insertion as well as the discomfort experienced from drug formulations. For patient comfort and adherence, it is critical to reduce injection pain.

High drug dosage (for example, therapeutic proteins) is required to obtain the therapeutic efficacy and administration frequency, and the drug formulations can be highly concentrated to reduce the injection volume. Observations in several studies showed that the formulation variables, for example, pH of the formulation, viscosity, salt concentration, and excipients may affect the discomfort from injection. On the other hand, injection volume, size of the needle, injection speed and angle of insertion also have a direct impact on the perceived pain or discomfort. The objective of this webinar is to educate the pharmaceutical industry about the use of Electromyogram (EMG) to assess and quantify discomfort by measuring muscle contraction evoked by the spinal reflexes in the animal.

This webinar will explore the optimization of critical factors (drug formulations and injection variables) in formulation development and device selection.
