Dosage form
Dosage forms are a mixture of active drug components and nondrug components (excipients). Depending on the method of administration they come in several types. These are liquid dosage form, solid dosage form and semisolid dosage forms. A Liquid dosage form is the liquid form of a dose of a chemical compound used as a drug or medication intended for administration or consumption. Common dosage forms include pill, tablet, or capsule, drink or syrup, and natural or herbal form such as plant or food of sorts, among many others. Notably, the route of administration (ROA) for drug delivery is dependent on the dosage form of the substance in question.
Various dosage forms may exist for a single particular drug, since different medical conditions can warrant different routes of administration. For example, persistent nausea and emesis or vomiting may make it difficult to use an oral dosage form, and in such a case, it may be necessary to utilize an alternate route such as inhalational, buccal, sublingual, nasal, suppository or parenteral instead.
