Which of the following forms of medication is typically used for quick delivery of drugs?

Injectable solutions are typically used for the quick delivery of drugs due to their ability to directly enter the bloodstream or targeted tissues bypassing the digestive system. This method allows for immediate therapeutic effects, which is especially crucial in emergency situations or when rapid onset of medication is required. Injectable solutions can include various forms such as intravenous (IV), intramuscular (IM), or subcutaneous (subQ) routes, each designed for different needs and speed of absorption.

In contrast, while creams, pills, and elixirs each have their own advantages and specific uses, they generally do not provide the same level of immediacy in drug delivery. Creams are often used for localized treatments, pills need to be digested and absorbed through the gastrointestinal tract, and elixirs, although liquid, still require time for the active ingredients to be metabolized and utilized by the body.
