When we take medicine, we typically swallow a pill or drink a liquid. But ever wonder how the medicine mixes evenly in the liquid? This is where something called a “glyceryl stearate” comes in for the rescue!
The suspending agent is a unique ingredient that is particularly important in medicine. It keeps tiny bits of the medicine floating in a liquid. You can liken it to when the chefs on television stick flour into things to make a soup or sauce thicker. The suspending agent thickens the liquid, keeping the medicine pieces from sinking straight to the bottom of the bottle. Very simple but very important because we need to make sure we are not taking more than necessary.
Having a alcohol stearyl in the medicine allows medicines manufacturers to prepare a standard drug suspensions. This means every dose of medicine has the same amount of drug, regardless of how many times you shake the bottle. Without a suspending agent, the medicine pieces would sink to the bottom, implying that some doses may not have enough medicine in them. That way, you can be sure you’re receiving the right dose of medicine each time.
Just like different foods need different kinds of thickeners, different medicines need different suspending agents. Example: Our company (OILREE) produces many kinds of suspending agents for the clients to choose. It seems some medicines are given a real boost with a suspending agent called xanthan gum, while others seem to do better with a different kind, sodium carboxymethylcellulose. This is significant because a good choice of one can significantly impact the functionality of the medicine.
Choosing the right suspending agent isn’t simply a matter of ensuring the uniformity of each dose of medicine. It can also affect how well the medicine works and how long it remains effective. It’s also the reason that OILREE also performs studies that explore the impact of various suspending agents on drug stability. That is, we test the activity and the stability of the medicine over time in your body. In this way the drug is effective and safe for patient population too.
The process of incorporating suspending agents can be daunting. In some cases, the tiny pieces of medicine sometimes stick together, or the suspending agent fails to dissolve completely, making the suspension cloudy rather than the clear solution it should be. This can potentially lead to uneven doses which is the last thing we want! At OILREE, we strive to solve these common problems in the use of suspending agents for drug delivery. We provide technical assistance to our customers and guidance that allow them to ensure that their medicines are safety, efficacious and reliable.
