What does API Pharmacology mean

API Pharmacology refers to the active ingredient of a drug, which is the core part of the drug.API is the abbreviation of ActivePharmaceuticalIngredient, which translates to Active Pharmaceutical Ingredient in Chinese.API Pharmacology is the study of the chemical structure of a drug, its molecular composition, its metabolism, and its pharmacodynamics, and aims to investigate the problems of drug efficacy, safety, and stability. It aims to investigate the efficacy, safety and stability of drugs.

The active ingredient of a drug is the most important part of the drug, which determines the therapeutic effect of the drug. The process of drug preparation is carried out on the basis of API.API pharmacological research focuses on how to prepare high purity and high activity of active ingredients of drugs by chemical synthesis, extraction or biotechnology.

The study of API pharmacology is very broad, and it includes many aspects of knowledge, such as the physicochemical properties of drugs, pharmacokinetics, drug metabolism, and pharmacodynamics, to name a few. Researchers need to know about the molecular structure of drugs, drug metabolic pathways, drug toxicity and drug dosage in order to better prepare effective and safe drugs.

In short, API pharmacology is a very important part of the drug development process, which focuses on the core components of a drug and explores issues such as efficacy, safety and stability. Through in-depth study of API pharmacology, we can better understand the nature and mechanism of action of drugs and provide strong support for the development of new drugs.

What does pharmaceutical api mean

Pharmaceutical api refers to an active pharmaceutical ingredient (Activepharmaceuticalingredient)1, also known as an API, which is any substance or mixture of substances that is used in the manufacture of a pharmaceutical product and which, when used in the manufacture of a pharmaceutical product, becomes an active ingredient of the pharmaceutical product.

Introduction to api

Api, meaning API. Any substance or mixture of substances intended for use in the manufacture of pharmaceuticals.

What does API mean in the pharmaceutical industry?


API (ApplicationProgrammingInterface) is a set of pre-defined Windows functions used to control the appearance and behavior of various parts of Windows, from the appearance of the desktop to the memory allocated to a new process. Each user action triggers one or more of these functions to run in order for Windows to tell what’s going on.

This is in some ways like the natural code of Windows. Other languages simply provide a way to access the API automatically and more easily. VB does a lot of work in this area. VB does a lot of work in this area. It completely hides the API and provides a completely different approach to programming in a Windows environment.

This means that every line of code you write in VB will be converted by VB into an API function to pass to Windows. . VB will call the API function TextOut with certain parameters (provided in your code, or default parameters).

Similarly, when you click a button on a form, Windows sends a message to the form (which is hidden from you), and VB gets this call and analyzes it to generate a specific event (Button_Click).

API functions are included in the Windows system directory in the dynamic connection library files (such as User32.dll, GDI32.dll, Shell32.dll …). .

API Declaration

As mentioned in “What is an API”, API functions are contained in DLL files located in the system directory. You can enter the API function declarations yourself, but VB provides a simpler way of doing this using APITextViewer.

To declare an API function in your project, simply run APITextViewer, open Win32api.txt (or .MDB if you’ve already converted it to a database) and you’re ready to go. This will speed up the process. Note: Microsoft’s file has a lot of shortcomings, you can try the site to provide the download of api32.txt), select the “Declaration”, find the desired function, click “Add” and “Copy”, and then paste (Paste) into your project. The same goes for using predefined constants and types.

You’ll run into some problems:

Suppose you want to declare a function in your form module. Paste it and run it, and VB will tell you: Compile Error…. .Declare statements are not allowed as Public members in a class or object module… It looks bad, in fact all you need to do is to add a Private in front of the statement (e.g. PrivateDeclareFunction…) . –Don’t forget, but this will make the function available only in that form module.

In some cases, you will get the “unclear name” message, because the function. This is because the function, constant or whatever is sharing a name. Since most functions (or maybe all, I haven’t verified) are aliased, meaning you can use other names than their original names via the Alias clause, you can simply change the function name and it will still work.

You can get a detailed description of Alias by looking at VB’s Declare Statements help topic.


Well, by now you know what an API function is, but you’ve also heard of messages (and if you haven’t, you will soon) and wondered what they are. Messages are Windows’ basic way of telling your program what events have occurred or to request a particular action. For example, a message is sent to your form when the user clicks a button, moves the mouse, or types text into a text box.

All messages sent have four parameters – a window handle (hwnd), a message number (msg) and two 32-bit long parameters.

hwnd that is to receive the message of a window handle, msg that is the message identifier (number). The identifier is the type of action that triggered the message (e.g., moving the mouse), and the other two parameters are additional parameters for the message (e.g., the current position of the cursor when the mouse is moved)

But why can’t you see the message when it’s sent to you — as if someone were stealing your mail? Please don’t be annoyed, I’ll tell you.

The thief is actually VisualBasic. But instead of stealing your mail, it reads it and picks out the important stuff and tells you in a nice way. That way is the Event in your code.

This way, when the user moves the mouse on your form, Windows sends a WM_MOUSEMOVE message to your window, VB gets the message and its parameters and runs your code in Event MouseMove, and VB takes the second 32 bits of the message (which contains the x,y coordinates in pixels). Pixel, 16 bits each) into two single precision numbers in Twip.

Now, if you need a pixel representation of the cursor coordinates, however, VB has already converted it to a Twip, so you need to reconvert it to pixels. Here, Windows gives you what you need, but VB “kindly” converts it so that you have to convert it again. You may ask – can’t I just receive the message myself? The answer is yes, you can use a method called subclass handling (Subclass). You can use a method called subclassing, but you don’t want to use it unless you have to, because it’s a little bit contrary to VB’s safe program design. (Note: Subclass processing does have a great deal of risk, but if used properly, is very useful. However, there is one thing you must pay attention to, that is, never use VB’s breakpoint debugging function, which may lead to VB crash!)

What needs to be added is: you can send a message to your own window or other windows, just call SendMessage or PostMessage (SendMessage will make the window that receives the message to immediately process the message, and PostMessage is to send the message to a queue called the message queue queue, waiting to be processed! (it will return after the message has been processed, e.g. with some delay)). You have to specify the handle of the window that will receive the message, the number of the message you want to send (all message numbers are constants, you can find them in APITextViewer) and two 32-bit parameters.

Another meaning:

1: American Petroleum Institute (API: AmericanPetrolenmInstitute): the organization that sets standards for motor oil. Engine oils for automobiles must meet the standards proposed by the API.

2: API also has a meaning: air pollution index. [English airpollutionindex abbreviation]

3: In JAVA, API in addition to the application of the “program program interface” means, but also refers to the JAVAAPI description of the document, also known as the JAVA help file.

4. APIQ1 quality system certification is to prove to the user that you have a set of API-recognized perfect quality management system, some oil and gas equipment manufacturers produce products that are not currently applicable to the API standard product specification counterparts, but they would like to prove to the user that their products or services in line with the requirements of the API standard, so APIQ1 quality system certification can help you do. APIQ1 Quality System Certification is particularly applicable to oil and gas equipment manufacturers whose products do not have a corresponding API standardized product specification, or companies that provide services to the oil and gas industry.
