Pharmaceutics: Overview of Biopharmaceutics

The science of preparation of drugs, dosage forms, and drug deliver systems, taking an account of the physicochemical properties, pharmacokinetics, and pharmacodynamics of the drug.

• Biopharmaceutics

• pharmacokinetics

• pharmaceutics

deals with the interrelationship between the physicochemical properties, the dosage form and the route by which a drug is administered, on the rate and extent of drug releases from the dosage form, and its subsequent absorption in the body.

• pharmaceutics

• biopharmaceutics

• pharmacokinetics

involves both mathematical and descriptive expressions of how the body handles the drug after its administration (the fate of the drug in the body), through absorption, distribution, metabolism, and excretion (ADME) processes.

• pharmacokinetics

• biopharmaceutics

• pharmaceutics

how drug is broken down and released from dosage form

• pharmacokinetics

• biopharmaceutics

• pharmaceutics

After absorption

• pharmacokinetics

• biopharmaceutics

• pharmaceutics

mass transfer process that involves the movement of unchanged drug molecules from the site of absorption to the bloodstream

• absorption

• distribution

• metabolism/biotransformation

• excretion

the reversible mass transfer of drug molecules from the systemic circulation to other parts of the body.

• absorption

• distribution

• metabolism/biotransformation

• excretion

represents drug elimination through enzyme-catalyzed chemical reactions

• absorption

• distribution

• metabolism/biotransformation

• excretion

denotes the physical removal of the drug from the body into bile, urine, feces, sweat, and air.

• absorption

• distrubtion

• metabolism/biotransformation

• excretion

All drugs go through the ADME process.

• True

• False

Answer explanation

It depends on the route the products are administrated.
