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.
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.
Balsalazide-azo-bonded prodrug, activated by bacteria in the colon
One example of a drug that is a prodrug activated by colonic bacteria when given orally is sulfasalazine. In the colon, bacteria cleave the molecule, releasing the active components, sulfapyridine and 5-aminosalicylic acid, which are then absorbed and exert their therapeutic effects in conditions such as ulcerative colitis and Crohn's disease.
dormant volcanoes. These volcanoes are not currently erupting but have the potential to become active again in the future.
No, since it has no surface, it has no geology.
No; Vyvanse is a prodrug that requires to be swallowed for the drug (dextroamphetamine) to become active. Smoking will produce no psychoactive effects and is dangerous for your health.
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.

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
cefpodoxime proxetil is a prodrug that is de-esterified in the GI tract. It becomes cefpodoxime free acid which is the active metabolite.

No, urine or blood cannot be used to activate Vyvanse for a high. Vyvanse (lisdexamfetamine) is a prodrug, meaning it must be metabolized in the body to become active. It is designed to be taken orally and converted into its active form through the digestive process. Attempting to use urine or blood in this manner is ineffective and dangerous.
Prodrug for Phenobarbital.

Yes. Although it is a "prodrug", meaning that it requires some metabolism in the body in order to become activated, Vyvanse is essentially an amphetamine compound.
No it's not a prodrug it works by acetylating the serine in the 530 position of COX and is then converted to salicylic acid which is inactive. It acts by preventing Arachadonic acid (AA) from entering the active site and forming PGG2, This is also true for COX2 even though it does allow AA to pass it doesn't form PGG2 instead forming 15-R-HETE.
