The difference between the dosage form of the preparation

In the chemical industry, the classification and selection of dosage forms is an important topic. Dosage form refers to the form formed after the drug or active substance is processed in a specific way, and its various forms directly affect the use effect, bioavailability and safety of the drug. This paper will analyze the differences, characteristics and applications of the dosage forms in detail.

Classification and Characteristics of Dosage Forms of 1. Preparations

1. Tablets Tablets are the most commonly used form of preparation and have direct contact properties. It is suitable for drugs with high absorption speed requirements, and the tablets are easy to process, store and transport. Apparent solubility and disintegration rate of tablets are the key indicators.

2. Granules Granules release the drug by dispersion control, suitable for long-term stable release of drugs. The controlled dispersion technology of granules can effectively prolong the use time of the drug while reducing gastrointestinal irritation.

3. Powder The powder has high apparent solubility and is suitable for bioavailability studies and controlled release studies. The powder has good fluidity and is suitable for various operations in the laboratory.

4. Liquid agent The liquid formulation has good biocompatibility and is suitable for broad-spectrum drugs. The administration route of the liquid formulation is flexible, and it is convenient to control the dosage and administration time of the drug.

5. Embryo Shell Clothes Formulation forms such as capsules and sugar coatings can control the release of drugs and are suitable for narrow-spectrum drugs. This formulation form has good stability and biocompatibility.

Key Factors in Dosage Form Selection of 2. Preparations

1. Drug properties and uses The physiochemical properties of different drugs determine the most suitable dosage form. For example, a drug with high bioavailability may require the selection of a controlled release formulation such as a powder or a sugar coating.

2. route of administration In intravenous administration, subcutaneous administration may require the choice of tablets or granules; while oral administration may require the choice of capsules or dragees.

3. � discredit

The choice of dosage form is also closely related to the administration needs of the patient. For example, the elderly or children may need to choose a preparation form that is stable and disintegrates slowly.

Case Analysis of Application of 3. Preparation Dosage Form

1. Application of Tablets in Lipid-lowering Drugs Tablets are often used in the preparation of lipid-lowering drugs because of their direct contact. Its apparent solubility and bioavailability are in line with the relevant standards, and it is a wide choice for clinical application.

2. Application of Granules in Antidepressant Drugs Granules can effectively delay the release of the drug through dispersion control technology, and are suitable for antidepressant drugs requiring long-term stability.

3. Application of liquid in antibiotics Liquid is one of the main forms of antibiotics because of its broad-spectrum action and flexibility of dosage control. Its high biocompatibility makes it suitable for use in a variety of clinical scenarios.

4. Summary

the choice of dosage form is a complex process, which requires comprehensive consideration of drug properties and uses, routes of administration and patient needs. Understanding the characteristics and application of different dosage forms is helpful to improve the efficiency of preparation development and application. In practical application, the most suitable dosage form should be selected according to the specific situation.
