Novel Drug Delivery System
Polymers are compounds with high molecular masses formed by monomers. In Greek, the word poly means 'many', and meros means 'units or parts'. Polymers play a major role in the development of drug delivery technolo…
1. Polymers used in colloidal drug carrier systems, consisting of small particles, show great advantage in drug delivery systems because of optimised drug loading and release properties. 2. A polymer (natural or synthetic) is a…
1. Drug Properties Drug solubility and dose are the most important factors to be considered in the design of ER matrices. In general, the extended-release formulation of an extreme drug solubilities coupled with a high dose is …
Physiological Properties (1) Aqueous solubility: Most of the active pharmaceutical moieties (API) are weakly acidic or basic in nature, which affects the water solubility of the API. Weak water-soluble drugs are difficult to d…
The primary objectives of controlled drug delivery are to ensure safety and to improve the efficacy of drugs as well as patient compliance. For conventional dosage forms, only the dose and dosing interval can vary, and for each d…
