Dosage Form

A dosage form is the physical form of a dose of medication, such as a capsule or injection. The route of administration is dependent on the dosage form of a given drug.Various dosage forms may exist for the same compound, since different medical conditions may warrant different routes of administration. For example, persistent vomiting may make it difficult to use an oral dosage form; in this case, it may be advisable to use either an injection or a suppository. Also, specific dosage forms may be warranted for certain medications, since there may be problems with stability, e.g. insulin cannot be given orally since it is digested by the gut.
