Prodrugs are big reversible derivatives of drug molecules that undergo an enzymatic and/or chemical transformation in vivo to release the active parent drug, which can then exert the desired pharmacological effect. In both drug discovery and development, prodrugs have become an established tool for improving physicochemical, biopharmaceutical or pharmacokinetic properties of pharmacologically active agents. About 5-7% of drugs approved worldwide can be classified as prodrugs, and the implementation of a prodrug approach in the early stages of drug discovery is a growing trend. Thanks to some Pharmaceutical company's, they gave their ability to rapidly create proprietary prodrug versions of each these cannabinoids, they stand to benefit from emerging data and increasing recognition from the medical community of the potent pain relief and anti-inflammatory effects of cannabinoids.
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
the work a machine does is the work output what it takes to do the work is the work input
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.

A prodrug becomes active when it is metabolized into its active form by the body's enzymes. This usually occurs after the prodrug is administered and travels to the site where it is converted into the active drug. Once activated, it can exert its therapeutic effect.
Prodrug for Phenobarbital.
A prodrug is a drug that is inactive when you take it (when it is administered), but then becomes active once your body starts to break it down (usually through metabolism). Stimulant simply refers to a class of drug. The opposite would be a non-stimulant. However, it is a different adjective describing the drug and is not part of "prodrug". That is, to be clear, the drug you're looking at is both a stimulant and a prodrug.

If the base hydrolysis mechanism is important, an electron withdrawing group can be attached to the prodrug. If the acid hydrolysis mechanism is important, an electron donating group can be attacked to the prodrug.
A prodrug actually has several biopharmaceutical benifits. First of all, it is important to understand the definition of a prodrug. A prodrug is a drug that is taken inactive, and through natural metabolic processes becomes active. One benifit is that a prodrug formulation actually increases the bioavailability of the drug. This means that if a drug is poorly absorbed by the body, a prodrug formulation of it can actually increase the amount of drug brought into the circulatory system (By making less polar/ionized). Next, this formulation can act as a vehicle to bring the drugs to specific areas of the body for usage. Drugs that need to pass the blood brain barrier for CNS affects can use a very lipid soluble vehicle bound to it to allow it to cross the barrier. Once the drugs gets to its target site, it is broken down by specific metabolic processes that present the active drug. Furthermore, a mutual prodrug is when both componants give pharmacotherapeutic affect. The Vigabatrin (GABA deaminase inhibitor), GABA (inhibbitory neurotransmitter), Fatty acyl ester (very lipid soluble) prodrug combination is a mutual prodrug in which the Vehicle takes the drug to the brain, the vigabatrin blocks the breakdown of GABA, and GABA is released. This prodrug is a treatment of Parkinsons disease as it increases the inhibition of the tremors and erratic movements associated with it. Finally, it also gives less side effects. Because of increased specificity (due to the fact only certain metabolic processes break down the prodrug, releasing its active componants at specific sites) their are a reduced amount of side effects. Hope this helps
Yes. It is a prodrug of an amphetamine.
Captopril is not used as a prodrug. It is an active drug itself, classified as an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension and heart failure by blocking the conversion of angiotensin I to angiotensin II.
The different types of carrier-linked prodrugs are bipartite, tripartite, and mutual. Bipartite structures consist of a carrier linked to a prodrug. Tripartite structues have a carrier linked to a drug via a linker. Mutual structures have two drugs linked to each other.
Yes, it is a prodrug of Phenmetrazine meaning a portion of it is converetd to Phenmetrazine by the liver. It has milder amphetamine like effects and therefore is less controlled as opposed to the amphetamines. Phenmetrazine and amphetamines are under strict Schedule II of the controlled substance act. Meanwhile Phendimetrazine is a less regulated Schedule III controlled substance. Yes it acts on the CNS like the amphetamines, but with less amphetamine like effects. An example of a milder Prodrug is Codeine. Codeine is a Prodrug of Morphine.
Psilocybin is a prodrug found in psilocybe (magic) mushrooms (along with psilocin and baeocystin). It is metabolized (dephosphorylated) into psilocin which the actual psychoactive.
