Abstract:
In the context of intraparenchymal delivery of therapeutic agents into brain parenchyma for the purpose of treating serious brain diseases, we present the scientific and medical need for infusion from a single source to cover a large area of the cerebral cortex, which we refer to as 'surface-contoured distributions' (SCD). The designs of two devices suitable for obtaining such SCD's are described, and the results of preliminary experimental studies with prototypes of them are reported. The studies were done in ex vivo samples of mammalian brain tissues, and histological sections of the brains confirmed that we had covered the large surface area desired. Work to test that the infusate penetrates the thickness of the cortex remains for the future.

Drug Delivery: Parenteral Route
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...
One-Compartment Model: IV Infusion
The one-compartment model for IV infusion uses mathematical equations to describe the rate of change in drug quantity in the body. At steady-state or infusion equilibrium, the drug input...
Routes of Drug Administration: Parenteral
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
