When is drug therapy used?

Treatment with any substance, other than food, that is used to prevent, diagnose, treat, or relieve symptoms of a disease or abnormal condition.

Are drugs or therapy better for mental health conditions?

For anxiety disorders, cognitive-behavioral therapy, antidepressant medications and anti-anxiety medications have all been shown to be helpful. Research generally shows that psychotherapy is more effective than medications, and that adding medications does not significantly improve outcomes from psychotherapy alone.

What is a therapeutic drug?

Therapeutic: Relating to therapeutics, the branch of medicine that is concerned specifically with the treatment of disease. The therapeutic dose of a drug is the amount needed to treat a disease..

What’s a therapeutic effect?

A therapeutic effect is a consequence of the medical treatment of any kind, the results of which are judged to be desirable and beneficial. This is true whether the result was expected, unexpected, or even an unintended consequence of the treatment.

What is adverse effect and side effect?

Side effects are unwanted symptoms caused by medical treatment. They’re also called “adverse effects” or “adverse reactions”. All medicines can cause side effects, particularly if you don’t use them as advised.

What is therapeutic range of a drug?

The therapeutic range of a drug is the dosage range or blood plasma or serum concentration usually expected to achieve the desired therapeutic effect. This does not mean that patients may not achieve benefit at concentrations below the minimum threshold, or may not experience adverse effects if kept within the range.

What is a good therapeutic index?

A higher therapeutic index is preferable to a lower one: a patient would have to take a much higher dose of such a drug to reach the toxic threshold than the dose taken to elicit the therapeutic effect….Therapeutic index.

What is narrow therapeutic range drugs?

Introduction. Narrow therapeutic index drugs are drugs where small differences in dose or blood concentration may lead to serious therapeutic failures and/or adverse drug reactions that are life-threatening or result in persistent or significant disability or incapacity.

What is half life of a drug?

What is a drug’s half-life? The half-life of a drug is the time it takes for the amount of a drug’s active substance in your body to reduce by half. This depends on how the body processes and gets rid of the drug. It can vary from a few hours to a few days, or sometimes weeks.

Which drug has the longest half-life?

However, there are numerous other drugs with very long half-life, examples are mefloquine 14–41 days (25), amiodarone 21–78 days (26), and oritavancin 393 h (27). Furthermore, what can be called “long half-life” is always relative to the length of the sampling period.

What made half-life so good?

Half-Life received acclaim for its graphics, realistic gameplay, and seamless narrative. It won over fifty PC “Game of the Year” awards and is considered one of the most influential FPS games as well as one of the best video games ever made.

What is Tmax and Cmax?

Cmax – the maximum concentration recorded. tmax – the time take to reach Cmax. AUC (Area Under the Curve) – a measure of the exposure to the drug. t1/2 (elimination half-life) – the time taken for the plasma concentration to fall by half its original value (shown in.

What does bioavailability mean in drugs?

More accurately, bioavailability is a measure of the rate and fraction of the initial dose of a drug that successfully reaches either; the site of action or the bodily fluid domain from which the drug’s intended targets have unimpeded access.[1][2][3] For majority purposes, bioavailability is defined as the fraction of …

What is flip flop phenomenon?

Flip-flop kinetics refers to when the rate of absorption of a compound is significantly slower than its rate of elimination from the body. Therefore, the compound’s persistence in the body becomes dependent on absorption rather than elimination processes. This sometimes occurs when the route of exposure is dermal.

How is C max calculated?

The Cmax can be determined in most statistical software packages by using the MAX function which selects the maximum value of a set of data. The Cmax is determined within the dosing interval.

What is the Cmax of a drug?

Cmax is the highest concentration of a drug in the blood, cerebrospinal fluid, or target organ after a dose is given. Related Term(s):

How is clearance calculated?

The clearance of substance x (Cx) can be calculated as Cx = Ax /Px, where Ax is the amount of x eliminated from the plasma, Px is the average plasma concentration, and Cx is expressed in units of volume per time.

How do you calculate the steady state of a drug?

The time to reach steady state is defined by the elimination half-life of the drug. After 1 half-life, you will have reached 50% of steady state. After 2 half-lives, you will have reached 75% of steady state, and after 3 half-lives you will have reached 87.5% of steady state.

How do you calculate the plasma concentration of a drug?

Maintenance dose rate (mg/hr) = [Cp (mg/L) x Cl (L/hr)] / F

  1. Cp represents the desired plasma concentration of drug.
  2. Cl represents the clearance rate of drug.
  3. F represents the bioavailability of drug (IV administration = 1)

How do you calculate blood concentration of a drug?

C (t) = C0 e – rt, where C (t) represents the concentration at time t (in hours), C0 is the concentration of the drug in the blood immediately after injection, and r > 0 is a constant indicating the removal of the drug by the body through metabolism and/or excretion. The rate constant r has units of 1/time (1/hr).

What is the steady state level of a drug?

Steady-state concentration is the time during which the concentration of the drug in the body stays consistent. For most drugs, the time to reach steady state is four to five half-lives if the drug is given at regular intervals—no matter the number of doses, the dose size, or the dosing interval.
