it describes the controlled drug release by diffusion or dissolution or both or swelling or erosion and which kinetics it follows either zero,first , higuchi or peppas
“It is a process by which a drug leaves a drug product
& is subjected to ADME & eventually becoming
available for pharmacological action.”
It involves the study of drug release rate, dissolution
/diffusion/erosion studies and the study of factors
affecting release rate of the drug.
Pulmonary route used to treat different respiratory diseases from last decade.
The inhalation therapies involved the use of leaves from plants, vapours from aromatic plants, balsams, and myhrr.
Pulmonary drug delivery is primarily used to treat conditions of the airways, delivering locally acting drugs directly to their site of action.
Delivery of drugs directly to their site of action reduces the dose needed to produce a pharmacological effect.
Dissolution, factors affecting drug dissolution, methods to evaluate dissolution, advantages and disadvantages, recent approaches--these are the topics covered in this presentation.
Liposomes-Classification, methods of preparation and application Vijay Hemmadi
liposome preparation and application
A liposome is a tiny bubble (vesicle), made out of the same material as a cell membrane. Liposomes can be filled with drugs, and used to deliver drugs for cancer and other diseases. Membranes are usually made of phospholipids, which are molecules that have a head group and a tail group

Controlled Release Oral Drug Delivery System
Controlled drug delivery is one which delivers the drug at a predetermined rate, for locally or systemically, for a specified period of time.
These systems are capable of controlling the rate of drug delivery, sustaining the duration of therapeutic efficacy, and/or targeting the delivery of drug to a tissue. Depending upon the technical sophistication, these rate-control drug delivery systems can be classified into three major categories: (i) pre-programmed drug delivery, (ii) activation-controlled drug delivery, and (iii) feedback-regulated drug delivery.
