There are numerous commercially available cellulosic controlled release ethers that find applications in multiple industries; Hydroxy Propyl Methyl Cellulose (HPMC) is more commonly used to regulate active pharmacokinetics and pharmacodynamics parameters. Various physico-chemical properties of polymers with release rate retardation indicate an effect on the dissolution of a controlled release tablet. Extensive literature indicates that the primary factor influencing the release of the drug was the hydroxypropyl material. In deciding the grade of HPMC polymers, the number of monomers also plays a significant role and influences drug release. When in contact with water, HPMC swells and contributes to drastic shifts in the concentration of polymers and medications and increases the scale of the dosage type. The embedded drug dissolves and diffuses as time passes. The rate of release or breakdown is dependent on the length of the chain and the degree of HPMC substitution used. The major rate release controlling mechanisms are absorption, swelling and erosion. This analysis focuses on numerous factors that influence the release of the drug, including structural characteristics.
