Wrong drug. This could occur when a patient is given medication that does not treat the patient's condition. Ex. A heart medication to treat an infection. [7] Dose too low. This could occur when a patient is given medication that is not strong enough to get beneficial or therapeutic effects. [7] Dose too high. This could occur when a patient is ...
Adverse effects, like therapeutic effects of drugs, are a function of dosage or drug levels at the target organs, so they may be avoided or decreased by means of careful and precise pharmacokinetics, the change of drug levels in the organism in function of time after administration. Adverse effects may also be caused by drug interaction. This ...
A pill splitter can be used to divide some tablets in half. This cuts the dose in half. Prescription drug doses are often based on body weight. [3] Drugs come with a recommended dose in milligrams or micrograms per kilogram of body weight, and that is used in conjunction with the patient's age and body weight to determine a safe dose.
As the drug is delivered to the site of action extremely rapidly with IV injection, there is a risk of overdose if the dose has been calculated incorrectly, and there is an increased risk of side effects if the drug is administered too rapidly. [25]
Therefore, if a drug has a bioavailability of 0.8 (or 80%) and it is administered in a dose of 100 mg, the equation will demonstrate the following: De = 0.8 × 100 mg = 80 mg That is the 100 mg administered represents a blood plasma concentration of 80 mg that has the capacity to have a pharmaceutical effect.
A few drugs such as alcohol are absorbed by the lining of the stomach, and therefore tend to take effect much more quickly than the vast majority of oral medications which are absorbed in the small intestine. Gastric emptying time can vary from 0 to 3 hours, [2] and therefore plays a major role in onset of action for orally administered drugs ...
It is the fraction of exposure to a drug (AUC) through non-intravenous administration compared with the corresponding intravenous administration of the same drug. [17] The comparison must be dose normalized (e.g., account for different doses or varying weights of the subjects); consequently, the amount absorbed is corrected by dividing the ...
Type A: augmented pharmacological effects, which are dose-dependent and predictable [5]; Type A reactions, which constitute approximately 80% of adverse drug reactions, are usually a consequence of the drug's primary pharmacological effect (e.g., bleeding when using the anticoagulant warfarin) or a low therapeutic index of the drug (e.g., nausea from digoxin), and they are therefore predictable.
