Drug Formulation Development

There're three main stages.

 

Pre-formulation studies

This stage involves the characterization of the physicochemical properties of the active pharmaceutical ingredient (API), similar as solubility, stability, particle size, and polymorphism. The thing is to identify the most suitable form of the API to use in the expression process. This stage also involves opting the excipients, similar as paddings, binders, disintegrants, and lubricants, which will be used in the expression.

 

Formulation design and optimization:

Once the pre-formulation studies are completed, the coming stage is to design a formulation that will ensure that the drug product meets the asked quality, safety, and efficacity conditions. This stage involves opting the applicable formulation strategy and optimizing the expression through several duplications of testing and analysis. The thing is to develop a formulation that's stable, bioavailable, and can deliver the needed cure of the API.

 

Drug delivery systems:

are designed to optimize drug delivery and ameliorate patient compliance. drug delivery systems can be classified into several categories based on their route of administration, similar as oral, transdermal, nasal, pulmonary, and parenteral delivery systems. The design of a drug delivery system involves opting the applicable dosage form and the system of drug release, similar as immediate release, sustained release, or targeted release.

 

 

 

Types of Drug Formulations

There are three main types of drug formulations solid, liquid, and semisolid dosage forms. Then are some exemplifications of each type:

 

Solid dosage forms

are the most generally used type of drug formulation. They're easy to administer, have a long shelf life, and are generally cheaper than other dosage forms. Some exemplifications of solid dosage forms include:

Tablets: Solid dosage forms that are made by compressing an admixture of API and excipients. Tablets can be carpeted to ameliorate their appearance, taste, and stability.

Capsules: Solid lozenge forms that are made by filling an external shell with a greasepaint or a liquid formulation. Capsules can be moreover hard or soft gelatine capsules.

Powders: Fine patches of API and excipients that can be administered orally or used topically. Powders: can be mixed with liquids, similar as water or juice, to form a suspense.

Granules: Small patches of API and excipients that can be used to make tablets or capsules. Granules can be coated to ameliorate their stability and bioavailability.

Sustained- release formulations: Solid lozenge forms that release the medicine over an extended period. Sustained- release formulations: can be designed to give a constant or shifting release rate.

 

Liquid dosage forms

Liquid dosage forms are used when the API cannot be formulated as a solid or when a rapid onset of action is needed.

Some exemplifications of liquid dosage forms include:

Solutions: Clear liquid formulation that contain the API and excipients. Solutions: can be administered orally, intravenously, or topically.

Suspensions:  Liquid formulation that contain undoable patches of API and excipients. Suspensions:  can be administered orally, intravenously, or topically.

Emulsions:  Liquid formulations that contain two immiscible liquids, similar as oil and water. Emulsions:  can be administered topically or intravenously.

Syrups: Liquid formulations that contain high concentration of sugar or other sweeteners. Syrups: can be administered orally.

 

Semisolid dosage forms:

are used when a medicine needs to be applied topically to the skin or mucous membranes. Some exemplifications of semisolid dosage forms include:

Creams: Semisolid formulations that contain a high percentage of water. Creams are used to deliver the medicine to the skin.

Ointments: semisolid formulations that contain a high percentage   of oil or petrolatum. Ointments are used to deliver the medicine to the skin.

Gels:  semisolid formulations hat contain a high percentage of water and a gelatinizing agent. Gels are used to deliver the medicine to the skin or mucous membranes.
