Is soil a degradation?
Soil degradation is the physical, chemical and biological decline in soil quality.
It can be the loss of organic matter, decline in soil fertility, and structural condition, erosion, adverse changes in salinity, acidity or alkalinity, and the effects of toxic chemicals, pollutants or excessive flooding..
What are the 3 phases of drug action?
Drug action usually occurs in three phases: Pharmaceutical phase. Pharmacokinetic phase. Pharmacodynamic phase.
How can drug stability be improved?
Drug stability can frequently be improved though the use of buffering agents between pH 5 and pH 6. Oxidation is another destructive process that produces instability in drug products. Oxidation is the loss of electrons from an atom or a molecule.
How does moisture affect stability of drugs?
It has long been known that moisture affects the stability of some drug substances. This presumes that the drug substance is not particularly hygroscopic, since, otherwise, the capsule shell will provide an unwanted source of moisture. …
What is the cause of degradation?
The main causes of the land degradation includes climate change, land clearance and deforestation, depletion of soil nutrients through poor farming practices, overgrazing and over grafting. In India, water erosion is the most prominent reason of land degradation.
What is oxidation in metabolism?
Listen to pronunciation. (OK-sih-DAY-tiv meh-TA-buh-lih-zum) A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, aerobic respiration, and cell respiration.
How can we prevent drug degradation?
Use of surfactant-based systems such as micelles can reduce the hydrolysis of hydrophobic drugs. Alternatively, preparing a suspension reduces the amount of drug in solution and hence may increase stability. A lyophilized product will remove water and significantly reduce the rate of hydrolysis.
What is drug oxidation?
Drug metabolism is the term used to describe the biotransformation of pharmaceutical substances in the body so that they can be eliminated more easily. … Drugs are metabolized through various reactions including: Oxidation. Reduction. Hydrolysis.
How does temperature affect drug stability?
When a drug is stored in temperatures that are too high or too low, the drug’s chemical stability will likely be impacted. That means that the drug may degrade and form impurities. While these impurities may not be visually noticeable, this degradation can cause real problems when the drug is administered.
What are the factors affecting ship stability?
Stability is determined by the force of buoyancy provided by the underwater parts of a vessel, coupled with the combined weight of its hull, equipment, fuel, stores and load. These forces can also be adversely affected by the prevailing weather conditions and sea-state.
What are the types of stability?
8.1 Different types of stabilityFreeze and Thaw Stability,Bench-Top Stability,Long-Term Stability,Stock Solution Stability,Processed Sample Stability.
What affects drug stability?
The degradation of drugs and drug metabolites in samples can occur through either reversible or irreversible processes. Common factors that affect this stability include temperature, light, pH, oxidation and enzymatic degradation.
What degradation means?
Degradation is the act of lowering something or someone to a less respected state. A president resigning from office is a degradation. It’s also a downcast state. Once the president has resigned, he might feel degradation. The noun degradation is related to the verb degrade, which comes from the Latin degradare.
What is shelf life of drug?
Shelf life is the period of time, from the date of manufacture, that a drug product is expected to remain within its approved product specification while stored under defined conditions. Shelf life is typically expressed in units of months, i.e. 24 months, 36 months, to a maximum of 60 months.
What are the factors that affect stability?
Common factors that affect this stability include temperature, light, pH, oxidation and enzymatic degradation. Special considerations are also required when dealing with chiral molecules, deuterated internal standards and large biomolecules.
In which class of drug no Ivivc is expected?
For orally administered drugs, IVIVC is expected for highly permeable drugs, or drugs under dissolution rate-limiting conditions, which is supported by the Biopharmaceutical Classification System (BCS) [6,16].
What is an example of degradation?
Degradation is defined as the state of being lowered down in respect, status or condition. When a person has become disrespected and is looked down upon, this is an example of degradation. A general lowering of the earth’s surface by erosion or weathering. … The lowering of land surfaces by erosion.
Which body organ is the major site of drug metabolism?
liverExcretion involves elimination of the drug from the body, for example, in the urine or bile. Most drugs must pass through the liver, which is the primary site for drug metabolism.
