Syrups are primarily sugar-based solutions, offering a sweet taste and high viscosity. Elixirs, on the other hand, are hydroalcoholic mixtures with a lower sugar content and a smoother, less syrupy texture. Syrups are primarily used for their pleasant taste and ease of administration, while elixirs are preferred for their better solubility of certain drugs.

Semi-solid dosage forms are a diverse group with varying consistencies. They can be classified into four major categories: Ointments (oleaginous, water-in-oil emulsions), Creams (water-in-oil or oil-in-water emulsions), Pastes (thick, stiff preparations with high drug concentration), and Gels (hydroalcoholic or water-soluble polymers).

Fried's and Clark's formulas are empirical equations used to estimate the dosage of drugs for children based on their age. Fried's rule applies to children under 2 years old, while Clark's rule is used for children between 2 and 12 years. Both methods aim to determine an appropriate dosage by taking into account the child's age and weight.

The sedimentation volume is a measure of the degree of settling of particles in a suspension. It is defined as the ratio of the height of the sediment to the total height of the suspension. A higher sedimentation volume indicates a less stable suspension as particles settle quickly.

Suppositories are solid dosage forms designed for rectal administration. They usually have a conical or bullet-shaped form, melt at body temperature, and release the drug within the rectum. These are mainly used for systemic or local drug delivery in a convenient way.
