Study Notes
Solid Dosage Forms
- Solid dosage forms include powders, granules, capsules, and tablets designed for medicinal use.
- Powders are dry preparations composed of finely divided particles for internal or external application.
- Topical powders are used externally, oral powders for ingestion, and insufflated powders for body cavities.
- Granules consist of dry aggregates or particles that can contain active pharmaceutical ingredients (APIs) and other ingredients.
- Capsules are gelatin shells containing medicinal agents, suitable for bulky drugs, and easy for infants/children to swallow.
- Tablets are formed by compression or molding and require dissolution for effect; they offer a large surface area and rapid onset of action.
Divided Powders
- Divided powders are mixtures of finely divided solids used internally or externally.
- They can be prepared using the block & divide method.
Effervescent Granules
- Effervescent granules include medicinal agents with acids like sodium bicarbonate, citric, and tartaric acid, creating effervescence when mixed with water.
- They mask undesirable flavors of medicines through carbonation.
Particle Size Determination
- Particle size can be determined through sieving.
Advantages and Disadvantages of Powders
- Disadvantages include limited dispensing to non-potent substances and easy spillage.
- Advantages include ability to mix with beverages, easy dosage adjustments, and potential for rapid onset of action.
Ointments
- Semi-solid preparations for external application to skin or mucous membranes are classified as ointments.
- Types include oleaginous, absorption, water-removable, and water-soluble bases.
Hydrophilic Ointment
- A water-removable ointment used as a protectant, comprising ingredients like methylparaben and propylparaben for antimicrobial properties.
Ointment Filling Procedure
- Steps include filling the jar, using spatulas to fill crevices, revealing air pockets, and ensuring a professional finish.
Cold Creams
- Cold creams serve as emollients and cleansing ointments using a water-in-oil emulsion base.
Zinc Oxide Paste
- Known as Lassar's paste, it contains 2% salicylic acid and 98% zinc oxide, offering antibacterial and antifungal properties.
Sulfur Ointment
- A parasiticide and keratolytic agent used to treat skin conditions like psoriasis and scabies, containing precipitated sulfur and mineral oil.
Key Differences
- White Ointment USP differs from Yellow Ointment USP in ingredient composition, with yellow wax replaced by a white wax in the former.
Stabilizing Agents
- Emulsifiers stabilize emulsions, while humectants like propylene glycol retain moisture.
