Sustained-launch drug shipping and delivery systems obtain the slow release of the drug in excess of an prolonged period of time following administration of only one dose.
The therapeutic index (TI; also known as therapeutic ratio) can be a quantitative measurement on the relative basic safety of a drug. It is a comparison of the amount of a therapeutic agent that causes the therapeutic result to the quantity that triggers toxicity. A therapeutic window or protection window refers back to the array of doses that optimize amongst efficacy and toxicity, accomplishing the best therapeutic gain without having leading to unacceptable Unwanted side effects or toxicity [45].
