This course builds a strong foundation for B Pharmacy Students all over the world.
Definition of Emulsifying Agents An emulsifying agent (or emulsifier) is a substance that stabilizes an emulsion by improving its kinetic stability. Emulsifiers work by reducing surface tension at the interface between the oil and water phases, making it easier to mix and stabilize the two phases. In pharmaceuticals, emulsifiers can also affect the bioavailability and … Read more
Definition of Emulsions Emulsions in pharmaceutics is a heterogeneous system consisting of two immiscible liquids (often oil and water), where one liquid is dispersed in the other as small droplets. Emulsion is typically unstable and require stabilizing agents (emulsifiers) to maintain the dispersion. Classification of Emulsions Oil-in-Water (O/W) Emulsion: Oil droplets are dispersed in a … Read more
Definition of Deflocculated suspension In a deflocculated suspension, solid particles remain discrete and uniformly dispersed throughout the liquid medium. While initially more uniform, these suspensions are prone to sedimentation and caking, making redispersion difficult. Preparation of Deflocculated Suspensions Particle size reduction: The solid drug is milled or micronized for proper dispersion, similar to flocculated suspensions. … Read more
Definition A flocculated suspension is one in which solid particles form loose, fluffy aggregates called flocs. These flocs settle quickly but can be easily redispersed upon shaking. Flocculated suspensions are preferred in pharmaceuticals due to their better stability and ease of redispersion. Preparation of Flocculated Suspensions Particle size reduction: The solid drug is milled or … Read more
Definition of Suspensions A suspension is a heterogeneous mixture in which finely divided solid particles are dispersed in a liquid medium. The particles in a suspension are larger than those in a solution and do not dissolve in the liquid. Over time, these solid particles settle out due to gravity, making suspensions distinct from solutions … Read more
Introduction to Biphasic Liquids: Biphasic liquids are systems consisting of two immiscible (non-mixing) liquid phases. These systems are commonly used in the pharmaceutical, cosmetic, and chemical industries. They are typically created when two liquids with different polarities, such as oil and water, are combined. Due to differences in polarity, these liquids do not mix and … Read more
1. Percentage Solutions: These are solutions where the concentration of a solute in a solution is expressed as a percentage. In pharmacy, this typically refers to: Weight/Volume (w/v) Weight/Weight (w/w) Volume/Volume (v/v) percentages. 2. Weight/Volume Percentage (w/v): Used for: Solid substances dissolved in a liquid. Definition: Expressed as grams of solute per 100 mL of … Read more
Lotions are liquid or semi-liquid preparations designed for topical application to the skin for various purposes, such as moisturizing, soothing, or medicating skin conditions. Preparation of lotions: Step-by-Step Preparation: Prepare Aqueous Phase: Heat water and dissolve any water-soluble ingredients (e.g., calamine or hydrocortisone) in the aqueous phase. Prepare Oil Phase: Heat the oil-based ingredients (e.g., … Read more
Liniments are liquid or semi-liquid preparations designed for topical application to the skin to relieve pain, inflammation, or muscle stiffness. They usually have a high concentration of active ingredients and are often applied with a massaging action to enhance absorption. Preparation of liniments: Step-by-Step Preparation: Select Base: Use oil (e.g., olive oil) or alcohol as … Read more
Elixirs are sweet, flavoured liquid preparations containing alcohol and used as a vehicle for administering oral medications. They are similar to syrups but have a lower viscosity and a higher alcohol content. Preparation of elixirs: Step-by-Step Preparation: Prepare Alcohol Base: Mix water and ethanol to form the hydroalcoholic solution. Dissolve Active Ingredients: Add the active … Read more
