Ocular Drug Delivery Systems

Ocular Drug Delivery Systems: Introduction

Ophthalmic treatments for eye diseases rely mostly on eye drop medication administered to the patients in an outpatient setting. Eye drop administration appears to be easy. However, patients with compromised eyesight may face difficulties. Additionally, drug action duration is shorter, requiring frequent administration (one to eight times a day). This results in the patients’ non-compliance, …

Intrauterine drug delivery systems

Introduction to Intrauterine Drug Delivery Systems

For a long time, the vagina was considered as an organ incapable of systematically absorbing drugs. The development of newer routes has made way to consider the vagina and the uterus as the administration routes. There are several benefits to it. These routes avoid the hepatic first-pass metabolism effect and allow female patients to self-administer …

Microencapsulation: Advantages and disadvantages

Microencapsulation means applying relatively thin coatings to small particles of solids or droplets of liquids or dispersions. It involves the coating of particles ranging from several tenths of a micron to 5000 microns in size. This technique is an effective means of converting liquids to solids by altering their colloidal and surface properties. It also …

Multiparticulate drug delivery systems

Constituents of multiparticulate drug delivery system

Multiparticulate drug delivery systems consist of three common constituents: microparticles, microcapsules, and microspheres. These microcarriers do not traverse through the interstitium and therefore produce local action. Multiparticulate Drug Delivery Systems: Major constituents Microparticles – These particles range from 1 to 1000 microns in size and are generally of spheroid shape. They have a well-known matrix or …
