Identifying Solid Dosage Forms
The question asked is which of the following is considered a solid dosage form. Looking at the options provided:
- Creams are semisolid emulsions that are not considered solid dosage forms. They can either be oil-in-water or water-in-oil and are typically used for their moisturizing effects or to aid in drug delivery through the skin.
- Emulsions are also not solid; they are a mixture of two immiscible liquids where one is dispersed in the other.
- Suspensions are heterogeneous mixtures where solid particles are dispersed within a liquid medium. Over time, these particles can settle out.
- Tablets, however, are a solid dosage form used for oral administration where the active ingredients are combined with excipients and compressed into a solid shape.
Therefore, the correct answer is d. tablet, which is recognized as a solid dosage form and is an effective means for delivering medication in a controlled dose.
