Venkata Ramanaapparao.chinnam@gmail.comP. Sai Mounikaapparao.chinnam@gmail.com<p>Regulatory compliance is an organization's adherence to laws, regulations, guidelines and specifications relevant to its business. Violations of regulatory compliance regulations often result in legal punishment, including federal fines. The International Organization for Standardisation (ISO) produces international standards such as ISO/IEC_27002. The International Electrotechnical Commission (IEC) produces international standards in the electrotechnology area. Compliance is about more than prevention. It’s also about navigating opportunities. Regulatory compliance is not just about playing defence. It also offers an opportunity to consistently strengthen your organisation through strategic, proactive measures—such as best practices, employee training, internal controls, and benchmarking appropriate for your industry and size.</p>2023-10-30T00:00:00+00:00Copyright (c) 2023 https://ijpar.com/ijpar/article/view/732Role Of Regulatory Affairs In Marketing Of Pharmaceutical Products2023-10-31T17:13:20+00:00Ancy Andrewancyandrew07@gmail.comD. Venkata Ramanaancyandrew07@gmail.comP. Sai Mounikaancyandrew07@gmail.com<p>The primary purpose of the rules governing medicinal products is to safeguard public health. However, this objective must be achieved by means which do not hinder the development of the pharmaceutical industry or trade in medicinal products within the Community. The Marketing Authorisation Holder (MAH) of a medicinal product is responsible for the quality, efficacy and safety of its products. The marketing authorization procedure includes an assessment of a dossier, in which the future marketing authorization holder (MAH) evidences the safety, efficacy, and quality of the product. Furthermore, the indications, contraindications, dosage of the product, general classification for supply, as well as the package leaflet for the patient and proposed texts on the labelling of the medicinal products are assessed. The Summary of Product Characteristics (SPC) forms part of the marketing Authorization. It serves as the key source of information about the medicinal product for doctors and healthcare professionals. Generic medicines are those where patent protection has expired, and which may be produced by manufacturers other than the innovator company. Use of generic medicines has been increasing in recent years, primarily as a cost saving measure in healthcare provision. Generic medicines are typically 20 to 90% cheaper than originator equivalents. As the Pharmaceutical industry is expanding by leaps and bound no single country is capable of manufacturing all the drugs in required quantities at competing prices. Hence the Marketing Authorizations has become an essential part of Global Healthcare. Till sometime back Marketing Authorization procedures were country specific. The present study describes a brief review of Marketing Authorizations in various countries and regions around the world (WHO).</p>2023-10-31T00:00:00+00:00Copyright (c) 2023 https://ijpar.com/ijpar/article/view/734Chemical structure and reaction schemes using chemdraw2023-11-10T10:32:50+00:00Garamsandh Gandhi Velusamyyasothaselvan@gmail.comKamalakannan Dhanabalanyasothaselvan@gmail.comR.

However, their short circulating half-life and restricted absorption via a defined segment of intestine limits the therapeutic potential of many drugs. Such a pharmaco kinetic limitation leads in many cases to frequent dosing of medication to achieve therapeutic effect. Rational approach to enhance bioavailability and improve pharmacokinetic and pharmacodynamics profile is to release the drug in a controlled manner and site-specific manner. Hence only our current research work is to prepare Nifedipine microspheresusing Solvent evaporation method using different polymer ratio. FT-IR studies revealed that there was no chemical interaction between the drug and polymer. The in vitro mucoadhesion study was conducted for all the formulations and the results were found in the range of 73.05 to 99.72%.The average particle size of the optimized formulation was found to be 166μm.
