It is distinct from dose, which denotes a single, specific quantity of a drug or substance given at one time. [2] Dosage typically includes information on the number of doses, intervals between administrations, and the overall treatment period. [ 3 ]
The infectious dose of a pathogen is the number of cells required to infect the host. All pathogens have an infectious dose typically given in number of cells. The infectious dose varies by organism and can be dependent on the specific type of strain. [21] Some pathogens can infect a host with only a few cells, while others require millions or ...
The ED 95 is the dose required to achieve the desired effect in 95% of the population. In anaesthesia, the term ED 95 is also used when referring to the pharmacology of neuromuscular blocking drugs. In this context, it is the dose which will cause 95% depression of the height of a single muscle twitch, in half of the population.
In pharmacokinetics, a loading dose is an initial higher dose of a drug that may be given at the beginning of a course of treatment before dropping down to a lower maintenance dose. [ 1 ] A loading dose is most useful for drugs that are eliminated from the body relatively slowly, i.e. have a long systemic half-life .
A combination drug (or fixed-dose combination; FDC) is a product that contains more than one active ingredient (e.g., one tablet, one capsule, or one syrup with multiple drugs). In naturopathy, dosages can take the form of decoctions and herbal teas, in addition to the more conventional methods mentioned above.
Consideration has to be given to what is known as "drug loading" - the ratio of the active drug to the total contents of the dose. A low drug load may cause homogeneity problems. A high drug load may pose flow problems or require large capsules if the compound has a low bulk density.

In pharmacokinetics, a maintenance dose is the maintenance rate [mg/h] of drug administration equal to the rate of elimination at steady state. This is not to be confused with dose regimen , which is a type of drug therapy in which the dose [mg] of a drug is given at a regular dosing interval on a repetitive basis.
