How many tablets is too many tablets a day?
At Dow Wolff Cellulosics, we are leading the effort in controlled release technology. Our goal is simple: ensure the right amount of a drug’s active ingredient is released from a tablet in the right place and at the right time.
Controlled release medication can mean the difference between taking a tablet once a day rather than once every few hours.
Trust the Dow Wolff Cellulosics Advantage

METHOCEL™ Premium Controlled Release (CR) Grade products have the properties needed to formulate controlled release tablets. That’s why they are the brand of choice for these systems.
- Controlled Drug Delivery: Our CR polymers hydrate the outer tablet surface to form a gel layer on contact with water. The diffusion out of the gel layer or the rate of tablet erosion can be designed to control the overall drug delivery rate. Conversely, our water-insoluble ETHOCEL™ Premium polymers are used in film and bead coating. Combined with our water-soluble METHOCEL™ Premium CR products, they help to leave a non-continuous film on tablets.
- Consistency: METHOCEL™ Premium CR cellulose ethers are specially engineered for pharmaceutical controlled release applications to deliver a consistent drug-release performance. Our proprietary techniques mean you can develop robust formulations quickly and then rely absolutely on their performance.
- Trust: Our CR products are fully certified and have an excellent safety record. We’ll happily provide all necessary data.
