Injections have become one of the most widely used dosage forms in clinical practice due to their rapid efficacy, accurate dosage and reliable action. Injections are generally divided into the following 5 categories: water-soluble injections, also known as water injections; oil-soluble injections, also known as oil injections; Emulsion type injection, also known as emulsion; suspension type injection; Sterile powder for injection, also known as powder injection.

In addition, a large dose of injection injected into the body by intravenous drip is also called an infusion.

The tablets are stable, the dosage is accurate, and they are easy to carry and apply, but infants and comatose patients cannot swallow them. In addition to the most common plain tablets, tablets also include coated tablets (divided into sugar-coated tablets and film-coated tablets), effervescent tablets, chewable tablets, multilayer tablets, dispersible tablets, sublingual tablets, oral tablets, implantable tablets, solution tablets and sustained-release tablets. For example, glycerinic tablets, acetaminophen film-coated tablets, aspirin enteric-coated tablets, vitamin C effervescent tablets, nitroglycerin sublingual tablets, compound borax mouthwash tablets, etc

It can also be made into compound tablets of two or more drugs to meet different clinical needs.

It is one of the commonly used oral dosage forms. It can be divided into hard capsules, soft capsules and enteric-coated capsules. Capsules can mask the bitter taste and special odor of the drug, and can also improve the stability and bioavailability of the drug, so that it can exert greater efficacy.

In addition, enteric-coated capsules do not dissolve until they enter the intestine, preventing stomach acid from destroying the drug's effect.

Including solutions, syrups, emulsions, suspensions, etc. The dosage of the liquid dosage form is easy to grasp and adjust, especially suitable for infants and elderly patients, and the drug is highly dispersed, absorbs quickly, and can exert its effect relatively quickly, but the liquid dosage form will be placed for a long time to reduce the efficacy or even invalidate, and it is easy to mildew, and it is inconvenient to carry.

Pharmaceutical dosage forms (abbreviated dosage forms) are different forms of administration prepared according to the needs of diagnosis, ** or prevention of diseasesSuch as powders, granules, tablets, capsules, injections, etc.

According to the different purposes and properties of the drug, different dosage forms of the drug can be prepared. Pharmaceutical preparations (abbreviated as preparations) are specific drugs, such as aspirin tablets, insulin injections, erythromycin ointment, etc. (generic name of the drug + dosage form).

The so-called pharmaceutical preparation, in a narrow sense, is a specific drug product prepared in a certain form, such as amoxicillin capsules, etc., in a broad sense, it is pharmaceutical preparation, is a discipline.

According to Article 102 of the Drug Administration Law of the People's Republic of China, the definition of drugs: drugs refer to substances used to prevent, diagnose and diagnose human diseases, purposefully regulate human physiological functions and stipulate indications, usage and dosage, including Chinese herbal medicines, Chinese herbal decoction pieces, and Chinese patent medicines.

Chemical raw materials and their preparations, antibiotics, biochemical drugs, radiopharmaceuticals, serum vaccines, blood products and diagnostic drugs, etc. Pharmaceutical preparations solve the problem of the usage and dosage of drugs.

Pharmaceutical preparations play a very important role in human beings. Pharmaceutical preparations are actually all around us. If we have a cold, we will take some cold medicine, some people take the capsule "Contec", and some people take the tablet "Gankang".

In fact, "capsules" and "tablets" are pharmaceutical preparations, and the effects of pharmaceutical preparations are generally divided into two categories.

Pharmaceutical dosage form: Any drug must be made into a form suitable for medical and preventive applications before it can be supplied for clinical use, and this form is called the dosage form of the drug, referred to as the drug. After the drug is made into different dosage forms.

It is convenient for patients to use and easy to accept, not only the dosage of the drug is accurate, but also increases the stability of the drug, sometimes reduces the toxicity, and also facilitates the storage, transportation and carrying of the drug. There are dozens of pharmaceutical dosage forms, and there are twenty or thirty commonly used ones.

Pharmaceutical preparations can reduce the pain for patients, and some people are sick and don't want to take medicine, because they hate the bitter taste of medicine, and the medicine is really bitter and hard to swallow. But once the medicine is made into a sugar-coated tablet, this is different, and the patient is not subjected to bitterness. Pharmaceutical preparations enable drugs to exert their effects and effects as "medicines".

Insulin is a protein that will be broken down and lose its effectiveness after being consumed by the human body, but insulin will be injected into the body of diabetic patients, which will play a leading role in diabetic patients.

Before any drug is supplied for clinical use, in order to meet different needs, it must be made into a form suitable for medical and preventive applications, that is, the raw materials are processed and manufactured into different forms, or appearances, so that they can act on different parts and play different roles, which is the dosage form, referred to as the drug.

The pharmaceutical dosage form is classified according to the substance form, namely: 1. Liquid dosage form: such as aromatic water agent, solution agent, injection, mixture, lotion, liniment, etc.

2. Gas dosage form: such as aerosol, spray, etc. 3. Solid dosage form:

Such as powder, pills, tablets, films, etc. 4. Semi-solid dosage form: such as ointment, suppository, paste, etc.

Before any drug is supplied for clinical use, in order to meet different needs, it must be made into a form suitable for medical and preventive applications, that is, the raw material is processed and manufactured into different forms, or appearances, in order to act on different large parts and play different roles, which is the dosage form, referred to as the drug.

The drug dosage form is classified according to the substance form, namely: 1. Liquid dosage form: such as aromatic water agent, solution agent, injection, mixture Liangmu, lotion, liniment, etc.

2. Gas dosage form: such as aerosol, spray, etc. 3. Solid dosage form:

Such as powder, pill, tablet, film, etc. 4. Semi-solid dosage form: such as ointment, suppository, paste, etc.

Analysis: Diagnosis, Sun Xumeng**, chemical substances that prevent disease, animal and plant products, minerals, etc. are called drugs or drugs

Drugs made from the above substances are called pharmaceutical preparations, or preparations for short.

The different forms, packaging states, and clinical uses of the preparations are called dosage forms, including: tablets, capsules, granules (formerly known as granules), solutions, injections (including injection injections, powder injections, lyophilized powder injections, etc.), suspensions, various external preparations, various ENT preparations, sustained-release and controlled-release agents, etc.

Pharmaceutical preparations mainly study the basic knowledge and skills of pharmacy, biopharmaceutics, industrial pharmacy, pharmaceutical preparation engineering, etc., and carry out the research and development, production, analysis, and quality inspection of pharmaceutical preparations. Common pharmaceutical preparations include sugar-coated tablets, enteric-coated tablets, capsules, ointments, sprays, injections, etc.

Extended information: The pharmaceutical preparation major cultivates senior scientific and technological talents with all-round development of morality, intellect, physique and aesthetics, with basic theoretical knowledge and basic experimental skills in pharmacy, pharmacy and pharmaceutical preparation engineering, and can be engaged in research, development, process design, production technology improvement and quality control in pharmaceutical preparations and fields related to preparation technology. Students in this major need to study physical chemistry, chemical engineering principles, medicinal chemistry, pharmaceutical analysis, pharmacology, physical pharmacy, pharmaceutical polymer materials, biopharmaceutics, industrial pharmacy, preparation equipment and workshop process design, etc.

1. Dosage forms are classified according to the route of administration

1. Transgastrointestinal administration of dosage forms has a first-pass effect on the liver, such as: oral administration.

2. There is no liver first-pass effect in non-gastrointestinal dosage forms, such as: injections, respiratory tract administration, ** administration, and mucosal administration.

2. Dosage forms are classified according to morphology: liquid dosage forms, gas dosage forms, solid dosage forms and semi-solid dosage forms.
