Pastills

Pastills, also known as lozenges, are solid oral dosage forms intended to be dissolved slowly in the mouth, delivering medication or other active ingredients locally or for systemic absorption. They are typically manufactured by compressing powdered or granular material into a smooth, often disc-shaped tablet. The primary purpose of a pastille is to provide a prolonged release of active substances, which can be beneficial for conditions requiring sustained relief, such as sore throats or coughs.

The formulation of pastills generally includes active pharmaceutical ingredients, excipients like binders, fillers, and flavorings, and a base material that allows for slow dissolution. Common base materials include sugars, gelatin, or gums, which contribute to the texture and dissolution rate. The slow dissolution process allows for extended contact of the active ingredient with the oral mucosa, facilitating local effects or absorption into the bloodstream.

Pastills are used for a variety of purposes. Medicated pastills can contain analgesics, antiseptics, antitussives, or decongestants to soothe sore throats, suppress coughs, or clear nasal passages. Non-medicated pastills may contain ingredients like zinc or vitamin C for immune support, or simply act as breath fresheners. The taste and texture are often designed to be pleasant, encouraging compliance with the dosage regimen. Their ease of use and portability make them a popular choice for self-medication and symptom relief.
