These oral solid dosage forms cater to various patient needs, preferences, and therapeutic requirements. The choice of formulation depends on factors such as drug characteristics, desired release profile, patient compliance, and ease of administration. Pharmaceutical scientists carefully select the appropriate type of formulation based on these considerations to ensure optimal drug delivery and therapeutic efficacy.
TYPES OF INJECTABLE FORMULATIONS
Injectable formulations are pharmaceutical products that are administered through injection, typically via intravenous (IV), intramuscular (IM), or subcutaneous (SC) routes. These formulations are designed to provide a rapid and precise delivery of drugs. Here are some common types of injectable formulations:
– **Injectable Solutions:** Clear and homogeneous liquid formulations containing one or more active pharmaceutical ingredients (APIs) dissolved in a suitable solvent.

– **Injectable Suspensions:** Formulations containing finely divided drug particles suspended in a liquid vehicle. These may require shaking or mixing before administration.
– **Oil-in-Water (O/W) Emulsions:** A dispersion of oil droplets in an aqueous medium. Commonly used for certain lipophilic drugs.
– **Water-in-Oil (W/O) Emulsions:** A dispersion of water droplets in an oily medium. Less common in pharmaceuticals.
– Dry, solid formulations obtained by removing the water content through freeze-drying. These powders are reconstituted with a diluent prior to injection.
– Lipid-based vesicles that encapsulate drugs. Liposomes can improve drug solubility and bioavailability and can be used for targeted drug delivery
– Particles in the nanometer size range that may be used to encapsulate drugs, improving their stability and delivery characteristics
– Large-volume solutions administered through a vein, often over an extended period. Used for drugs requiring continuous infusion.
– Sterile solutions or suspensions administered into the muscle tissue.
– Sterile solutions or suspensions administered into the fatty tissue beneath the skin.
– Ready-to-use syringes containing a specific dose of drug. Enhances convenience and reduces the risk of dosing errors.
TYPES OF ORAL LIQUID DOSAGE FORMULATIONS
– Solutions containing a high concentration of sugar or sugar substitutes to enhance taste.
– Often used for paediatric and geriatric populations.
– Formulations containing finely divided, undissolved drug particles dispersed in a liquid vehicle.
– Require shaking before administration to ensure uniform distribution.
– Formulations consisting of small droplets of oil dispersed in an aqueous medium.
– Typically used for drugs with poor water solubility.
– Clear, sweetened, and hydroalcoholic solutions.
– May contain flavouring agents to improve taste.
– Alcoholic or hydroalcoholic solutions of drugs, often plant extracts.
– Typically used in herbal medicine..
– Homogeneous mixtures of one or more drugs dissolved in a liquid vehicle.
– Generally easier to manufacture compared to suspensions.
– Solutions delivered in drop-wise fashion using a calibrated dropper.
– Commonly used for paediatric dosing.
– Dry, powdered forms that require reconstitution with a specified volume of water or another liquid before administration.
– Particles containing the drug and other excipients, often in a sugar or flavoured base.
– May be taken directly or dissolved in water before administration.
– Contain a combination of citric acid and sodium bicarbonate that effervesces when dissolved in water.
– Provide a fizzy and palatable form.
– Concentrated, syrupy solutions, often containing therapeutic agents for respiratory conditions.
– May include soothing agents like honey..
– Liquid formulations designed for oral hygiene or treatment of local conditions in the mouth or throat.
– Highly concentrated liquid formulations administered in small drops.
