For decades, the regulation and control of new drugs in the United States has been based on the New Drug Application (NDA). Since 1938, every new drug has been the subject of an approved NDA before U.S. commercialization.  The NDA application is the vehicle through which drug sponsors formally propose that the FDA approve a new pharmaceutical for sale and marketing in the U.S.  The data gathered during the animal studies and human clinical trials of an Investigational New Drug (IND) become part of the NDA.

The goals of the NDA are to provide enough information to permit FDA reviewer to reach the following key decisions:

The documentation required in an NDA is supposed to tell the drug's whole story, including what happened during the clinical tests, what the ingredients of the drug are, the results of the animal studies, how the drug behaves in the body, and how it is manufactured, processed and packaged.  The following resources provide summaries on NDA content, format, and classification, plus the NDA review process:

The following resources have been gathered to provide you with the legal requirements of a new drug application, assistance from CDER to help you meet those requirements, and internal NDA review principles, policies and procedures.

Guidance documents represent the Agency's current thinking on a particular subject. These documents are prepared for FDA review staff and applicants/sponsors to provide guidelines to the processing, content, and evaluation/approval of applications and also to the design, production, manufacturing, and testing of regulated products.   They also establish policies intended to achieve consistency in the Agency's regulatory approach and establish inspection and enforcement procedures.  Because guidances are not regulations or laws, they are not enforceable, either through administrative actions or through the courts.  An alternative approach may be used if such approach satisfies the requirements of the applicable statute, regulations, or both. For information on a specific guidance document, please contact the originating office.

For the complete list of CDER guidances, please see the Guidance Index.  For information on a specific guidance document, please contact the originating office.

Guidance documents to help prepare NDAs:.

The mission of  FDA is to enforce laws enacted by the U.S. Congress and regulations established by the Agency to protect the consumer's health, safety, and pocketbook.  The Federal Food, Drug, and Cosmetic Act is the basic food and drug law of the U.S. With numerous amendments, it is the most extensive law of its kind in the world.  The law is intended to assure consumers that foods are pure and wholesome, safe to eat, and produced under sanitary conditions; that drugs and devices are safe and effective for their intended uses; that cosmetics are safe and made from appropriate ingredients; and that all labeling and packaging is truthful, informative, and not deceptive.

The final regulations published in the Federal Register (daily published record of proposed rules, final rules, meeting notices, etc.) are collected in the CFR.  The CFR is divided into 50 titles which represent broad areas subject to Federal regulations.  The FDA's portion of the CFR interprets the Federal Food, Drug and Cosmetic Act and related statutes.  Section 21 of the CFR contains all regulations pertaining to food and drugs.  The regulations document all actions of all drug sponsors that are required under Federal law.

These documents are approved instructions for internal practices and procedures followed by CDER staff to help standardize the new drug review process and other activities. MaPPs define external activities as well. All MaPPs are available for the public to review to get a better understanding of office policies, definitions, staff responsibilities and procedures.

MaPPS of particular interest to NDA applicants

On November 21, 1997, The President signed the Food and Drug Administration Modernization Act of 1997.  This legislation includes authorization for FDA to continue to collect three types of user fees from applicants who submit certain new drug and biological product applications.  FDA was first authorized to collect user fees under the Prescription Drug User Fee Act (PDUFA) of 1992.

Advisory committees provide independent advice and recommendations to the FDA on scientific and technical matters related to the development and evaluation of products regulated by the Agency.  CDER requests advice from advisory committees on a variety of matters, including various aspects of clinical investigations and applications for marketing approval of drug products.  Committee members are scientific experts such as physician-researchers and statisticians, as well as representatives of the public, including patients.  Although the committees provide recommendations to the Agency, final decisions are made by FDA.

The scope of the article

The article gives a basic understanding of the inversion of a number.

There are different methods to implement the same thing.

One needs a basic understanding of C/C.

Understand how loops and recursion work.

When reversing a number, you swap the digits so that the last digit of the number is first or second.

Let us use an example to understand the same.

The input is 56897

The reverse of the number would be 78265.

Since we know what it means to change a number, let's deepen our understanding.

First step. The given number is num. Consider the inverse number to be 0

The given formula will be used.

The rev_num is 10 and the num%10 is 10.

The number is 10

We can fit the last digit of the number into r ev_num by taking the last digit and dividing it by 10.

We'll divide num by 10 and keep that value in num.

The procedure will continue until the number is less than or equal to 0

We obtained our inverse number once we reached that stage.

After the fifth iteration, we'll get our inverse number, that is, 79865.

The modulo and division operator are used.


The reverse of the given number is represented by the symbol revnum.

If the number is represented by 'n', we will return our inverse number.

In all other cases, reversenumber will be called with updated values of n and k.


Humans can interpret many languages, but the computer only handles the numbers in a certain order. Positive and negative numbers have different representations.

If we apply the above method directly to a negative number, it will produce an incorrect answer. To avoid this, we will use the inverse number and the negative number to make it a positive number and then use the inverse number and the negative number again to make it a negative number.

The given code will help to understand this.
