Dt = Dose (1 + 0.693 × t/t1/2)
Where,
Dt = Total dose,
Dose = Immediate release dose,
t = Total time period for which sustained release is required,
t1/2 = Half-life of drug.
Depakine 500 is an immediate-release formulation of sodium valproate, while Depakine Chrono 500 is a controlled-release formulation. This means that Depakine Chrono releases the medication slowly over time, providing a more consistent blood level compared to Depakine 500, which releases the medication more rapidly. Your doctor will determine the appropriate formulation based on your specific needs.
Controlled release OxyContin is designed to release the medication over a specific period to provide consistent pain relief, while modified release OxyContin may release the medication at different rates based on the formulation, but still provides extended pain relief. Controlled-release OxyContin is often used for chronic pain management where consistent blood levels are required, while modified-release OxyContin may be used for varying durations of pain relief.
HCL stands for hydrochloric acid, which is the chemical compound found in the stomach that aids in digestion. ER stands for extended-release, which refers to a medication formulation designed to release the drug over an extended period of time in the body. They are different in terms of their chemical composition and purpose.
CPCR (controlled-potency controlled-release) medications provide a consistent release of the active ingredient over time, maintaining a steady level in the body. TBCR (time-controlled burst-release) medications release the active ingredient all at once, providing a rapid onset of action followed by a decrease in concentration over time.
To determine the heat of combustion for a substance, one can conduct a calorimetry experiment where the substance is burned in a controlled environment and the heat released is measured. This heat release is then used to calculate the heat of combustion for the substance.
Matrix tablet is a specific formulation intended for slow/controlled/sustained release of drug at a desired location in gastro-intestinal tract.
Depakine 500 is an immediate-release formulation of sodium valproate, while Depakine Chrono 500 is a controlled-release formulation. This means that Depakine Chrono releases the medication slowly over time, providing a more consistent blood level compared to Depakine 500, which releases the medication more rapidly.

Most simply, they are two different drugs. Concerta is a sustained-release formulation of methylphenidate, and Adderall XR is an extended-release formulation of a mixture of amphetamine salts. It's like the difference between Ritalin and Adderall, which are the immediate-release forms. Both drugs are stimulants, usually prescribed for ADD/ADHD. Methylphenidate is said to not be as strong a stimulant as amphetamine, but is still controlled as tightly.
The Higuchi model is a mathematical model used in pharmacokinetics to describe drug release from a controlled-release formulation. It is based on Fick's second law of diffusion and describes drug release as a function of the square root of time. The model is commonly used to analyze drug release kinetics from matrix systems.
Journal of Controlled Release was created in 1984.
Bio-Melatonin is a branded product containing 3mg of melatonin in an immediate release formulation.
HCL stands for hydrochloric acid, which is the chemical compound found in the stomach that aids in digestion. ER stands for extended-release, which refers to a medication formulation designed to release the drug over an extended period of time in the body.

One is an adhesive and one is a hardener. None of them will release exact formulae.

Controlled release capsules usually have a coating that causes the medicine to enter the system, instantly, at a later time. Extended release drugs are actually released slowly.
