Introduction

Definition: Phytopharmaceutical drugs

"PhytoPharmaceuticals drug" is defined as "processed or unprocessed standardised materials derived from plants or parts thereof, or combinations of parts of plants, extracts or fractions thereof in a dosage form for internal or external use of human beings or animals and intended to be used for diagnosis, treatment, mitigation, or prevention of any disease or disorder in human beings or animals," according to a gazette notification dated October 24, 2013, but does not include administering.

Newphytopharmaceutical drug: As defined in the Act, bulk drug substance that has not been recognized as effective and safe by the licencing authority mentioned under rule 21 for the proposed claims and has not been used in the country to any significant extent under the conditions prescribed, recommended, or suggested in the labelling.

Herbalmedicinal products: Medicinal products that only contain herbal medication preparations as active ingredients, such as comminuted sections of plants, extracts, pressed juice, or distillates of plants.

Homeopathic medicinal goods, as well as isolated plant elements like digitoxin or menthol, are not considered herbal medicinal products.

Ayurvedic medicine: Ayurveda, or ancient Indian medicine, is based on ancient literature that emphasize a "natural" and holistic approach to physical and mental health.

Ayurvedic medicine is one of the world's oldest medical systems, and it is still practiced in India today, Ayurvedic treatment includes a combination of products (mostly from plants, but also from animals, metals, and minerals), diet, exercise, and way of life.

Ayurveda

Science of life: All objects and living organisms, according to Ayurveda's fundamental principles, are made up of five basic components known as the Pancha Mahabhootas:

• Prithvi (earth)

• Jal (water)

• Agni (fire)

• Vayu (air) and

• Akash (fire) (ether).

The Ayurvedic philosophy is founded on the basic relationship between the universe and man.

As a result, Ayurveda has placed a strong emphasis on environmental issues and has recommended a variety of steps to protect the environment as well as to avoid contamination of the air, water, and soil, Ayurveda follows the humoral theory of Tridosha, which consists of three physiological entities in living beings: Vata (ether + air), Pitta (fire), and Kapha (earth + water), which are responsible for all metabolic operations.

About Phytochemicals are organic substances produced by plants that have a low molecular weight. Polyphenols, carotenoids, and glucosinolates can be grouped into three classes based on structural properties. They're made by primary and secondary plant metabolism, and they have a variety of functions in plants.

Drug Development Process Components: Phytomedicine

1. Identifying and prioritising R&D requirements

2. Review of the literature

3. Formulation of a hypothetical rationale

4. Initiation of drug development (Quality Control, Quality Assurance)

5. Biological activity, stability tests, and preclinical research (With Standard Protocol)

6. Development of integrated protocols for clinical trials (GCP & traditional process)

7. Standard process for clinical trials of new drugs and regulatory authority approval.

Importance of Phytomedicines during Pandemic COVID-19

• Phytopharmaceuticals are herbal medicines that rely on one or more plant components or active elements for their effectiveness.

• They've been utilised to treat ailments from the beginning of time, today Phytomedicines has grown in importance and continues to improve for the betterment of human health.

• In contrast to current medical systems, herbal medicine plays a key role in the development of new medications. There has been a dramatic development in Phytomedicines around the world for more than a decade.

• Phytopharmaceuticals generated from medicinal plants could be investigated as major resources in the development of COVID-19 treatment, given their history of use in the treatment of viral infections such as HIV and influenza.

• In light of this, the present study looked at various phytoconstituents such as flavonoids, alkaloids, tannins, and glycosides that have antiviral effects against coronaviruses and have promise against SARS-CoV-2. The Ministry of Health and Family Welfare, Government of India, notified the regulatory standards for Phytopharmaceuticals, which contain scientific data on the quality, safety, and efficacy of a herbal medication, comparable to synthetic, chemical compounds.

• The pharmaceutical and cosmetic industries are drawn to plant-based natural products like as extracts, bioactive fractions, essential oils, phytomolecules, flavours, and perfumes.

• AYUSH and CDSCO have developed a set of recommendations for Phytopharmaceuticals medication manufacturing. In general, herbal pharmaceuticals are poorly regulated and supervised by health authorities, thus efforts are made to ensure that the component is analytically controlled and standardised for therapeutically safe medication.

• The new phytopharmaceuticals regulation stimulates and authorises the creation of plant-based medications employing improved solvent extraction, fractionation, potentiating processes, current formulation development, and other techniques.

• The advancement of Phytopharmaceuticals technology, as well as hopes for treatments for chronic diseases, sparked renewed interest among researchers in developing herbal medicine.

• Anti-cholinergic, anti-malarial, and ant-cholinesterase’s have been designed and synthesised using belladona alkaloids, quinine, physostigmine, cocaine, opiates, codeine, and salicylic acid as models.

• During the treatment of chronic diseases, the appearance of adverse effects following long-term use of synthetic medications is always feared.

• Following their expanded use in the food and cosmetic industries, the trade in plant products has increased. India is the leading supplier of psyllium and sandal wood oil, as well as opium alkaloids.

The Current State of Global Regulation

• In the United States, Phytopharmaceuticals are essentially the same as botanical medications.

• The regulatory environment for herbal remedies differs from one country to the next.

• Traditional usage, well-established use, and standalone/mixed application are the three types of herbal preparations in Europe.

• Botanical Drug Development Guidance from the FDA outlines proper development strategies for botanical medications that should be presented in new drug applications (NDAs) as well as specific submission requirements (INDs).

• Ayurveda, Unani, Siddha, and Homeopathy (ASU) medications are regulated by the Department of AYUSH in India.

• The Central Drugs Standards Control Organization, on the other hand, is in charge of PhytoPharmaceuticals regulatory standards in 2015 (CDSCO).

This gazette notification (Schedule Y, Appendix I B) establishes regulatory provisions for PhytoPharmaceuticals as well as regulatory submission requirements for scientific data on quality, safety, and efficacy in order to evaluate and permit the marketing of herbal drugs in the same way that synthetic, chemical moieties are marketed.

Phytopharmaceutical Distinguishing Features

• PhytoPharmaceuticals can come from any corner of the world and have a botanical origin, its plan complies with the law.

• Scientific evaluation in the United States, China, and other countries as well as data collection. It isn't just reliant on traditional methods.

• The idea of Phytopharmaceuticals would encourage inventing and developing novel medications based on botanicals.

• It would be done in a scientific manner, and it would boost drug reserch,invention, industry, and national laboratories development in India, as well as pharmaceutical research labs.

• As proposed above, adherence to the D and C Rules, as well as drug development technologies involving current solvent extraction, fractionation, and other procedures contemporary extraction, potentiating stages, add-back procedures methods (such as CO2) freezing, as well as a variety of other approaches.

• Ayurvedic pharmaceuticals are governed differently, and they must meet the conditions outlined in authoritative documents and be handled according to the timetable.

• The Phytopharmaceuticals leaders can have their origins not only in TMs such as ASU, but also in Traditional Chinese Medicine.

• Medicine, Kampo Medicine, Bhutanese Medicines, or a combination of the three Ethnobotany, indigenous medical practises, and other sources of information are available.

• Phytopharmaceuticals would have to be examined for safety, through well-conducted human trials, safety (toxicology) and efficacy, Clinical trials on the same lines as synthetic compound-based medications are being conducted.

• Ayurvedic medications are exempt from such legal regulations, it’s also necessary to have knowledge of potential mechanisms of action.

• Phytomedicines When certified by the Drug Controller General of India, will have the same marketing status as synthetic drugs a medication that is based on a chemical

These draughts were developed by a committee. The Drug Technical Advisory Board (DTAB) has established regulations -the drug law's statutory agency that advises the central government on drug-related technical issues, the government has made a recommendation.

Regulation of Phytodrugs: In India

• In contrast to AYUSH regulations, the Central Drugs Standards Control Organization is responsible for PhytoPharmaceuticals regulatory requirements in 2015. (CDSCO). This notice was published in the Gazette.

• Defines PhytoPharmaceuticals regulatory provisions and regulations governing the submission of scientific data on quality.

• To examine and allow the sale of a herbal product, researchers looked at its safety and efficacy.

• Medication that works in a similar way as synthetic chemical moieties when everything is dubious with traditional medications.

AYUSH PhytoPharmaceuticals is a well-balanced drug that trusts everything, strategy that trusts everything but emphasises the need for revalidation the plant's material specifications:

◊ Acts administered in the Indian system of medicine sector

◊ Central Council of Indian Medicine Act-1973

◊ Central Council of Homoeopathy Act-1973

◊ Drugs and Cosmetics Act-1940 and Rules there under

◊ Drugs and Magic Remedies Act-1954, 1955 and Rules there under

◊ Medicinal and Toiletries Preparation acts and Rules-1995.

Problems with regulation of herbal products:

◊ Quality control

◊ Safety of the herbal preparations

◊ Development of effective marker

◊ Clinical efficacy of marker

◊ Documentation

◊ Regulatory harmonization.

Regulatory Criteria for NDAS of Various Herbal Medication Classes

Botanical Drug Development Guidance from the FDA specifies appropriate development techniques for botanical medicines that should be included in new drug applications (NDAs), as well as specific recommendations for submitting investigational new drug applications (INDAs),The term botanical refers to plant materials, algae, microscopic fungi, and combinations of these, An IND must include enough information to prove that the treatment is safe for human testing and that the trial protocol is properly constructed for its intended aims, according to FDA standards (Bhatt, 2016).

There are additional needs for botanical pharmaceuticals to ensure their safety and quality, in addition to the standard regulatory requirements for an NDA, which include nonclinical pharmacology/toxicology investigations, clinical evidence of efficacy, and safety.

Phytopharmaceutical standardisation

The plant utilised for extraction and fractionation was identified, authenticated, and the source of the data was generated.

Extraction procedure followed by fractionation and purification Details of a PhytoPharmaceuticals drug's formulation, Formulation manufacturing process, and data on stability.

Checking harvest location, growth conditions, stage of plant growth at harvest, harvesting time, checking collection, washing, drying, and storage conditions, way of handling, garbling, transportation, grinding, pulverisation of plant material, sieving for uniform particle size of powdered plant material, followed by authentication of plant material, presence of phytotoxins, foreign matter, volatile matter, radioactive uranium, and other secondary processing information.

Standardized phytopharmaceutical

According to the Indian Pharmacopoeia of 2014, a standardized extract is one that has been adjusted to a given content of biomarker or chemical/ analytical marker within an acceptable tolerance.

Standardization can be achieved by combining one or more batches of extracts or modifying the extracts with permitted inert material.

According to the European Pharmacopoeia, standardization refers to the addition of excipients or the blending of herbal medications or herbal preparations to achieve a defined quantity of a constituent or a combination of compounds with proven therapeutic efficacy.

Regulatory Requirement of Phytopharmaceutical in Europe

• HMPC (Herbal Medicinal Products Committee) (EMA), National competent authorities of Member States can contact the HMPC for scientific and regulatory aspects of applications.

• Directive 2004/24/EC, which revised Directive 2001/83/EC's basic legislation, transformed the European Union.

• The purpose of this act was to ensure that such commodities would continue to exist and that specified features would be considered when evaluating their quality, efficacy, and safety, therefore it classified herbal medicines into two categories:

(a) HMPs with a long history of usage for which a marketing authorization can be given and

(b) Traditional herbal medical items that can be registered due to their long history of safe and effective use.

Marketing Authorization, Regulatory Pathway for Phytomedicine in EU

Centralized procedure

Submission of an EMA application, one marketing authorization obtained by the European Commission, valid throughout the EU, 210 days plus the time it takes the European Commission to make a decision, there is only one cost, European Community Regulation (EC) No 726/2004.

Decentralized procedure

Simultaneous authorization in more than one Member State, Directive 2004/27/EC, Directive 2001/83/EC, 210 days + 30 days (national phase) Fee per member state (RMS, CMS).

Mutual recognition procedure

Allows Member States to rely on each other’s scientific assessments, Directive 2001/83/EC ▪ 90 days + 30 days (national phase) Fee per member state (RMS, CMS).

National procedure

Authorization by a single MS, No existing MA in the EU, 210 days (Table 1).

European Union monographs

A European Union (EU) herbal monograph (formerly known as Community herbal monograph) contains the HMPC scientific opinion on safety and efficacy data about a herbal substance and its preparations intended for medicinal use.

Sections of an EU herbal monograph:

• Pharmaceutical form

• Clinical, pharmacological properties.

• Qualitative and quantitative composition

Legal framework

In 2004, the European Commission issued Directive 2004/24/EC (the Herbal Directive), which updated Directive 2001/83/EC and provided a simpler registration system for traditional herbal medical goods, Its purpose is to protect public health while simultaneously allowing free movement of herbal medical products across Europe, While the majority of herbal medicinal products are still regulated at the national level by Member States, the licensing process for herbal components and preparations is becoming more standardized across the EU.

The Herbal Directive allows all Member States to refer to a single set of information on a herbal ingredient or herbal preparation when reviewing marketing applications for herbal therapeutic goods from enterprises, Herbal medicines are being more widely used in primary healthcare for individuals and communities in many nations, owing to a growing interest in traditional and alternative medical systems, By enacting Directive 2004/24/EC, which updates Directive 2001/83/EC, the European Union (EU) has established a regulatory framework for herbal medical products (HMPs),On behalf of the European Medicines Agency, the Committee on Herbal Medicinal Products (HMPC) publishes scientific opinions on herbal compounds and preparations, as well as information on recommended uses and safe conditions (EMA) [1-7] (Table 2).

Conclusion

Importing or manufacturing a new PhytoPharmaceuticals drug in India requires a licence. Fill out Form 44, Import Registration & Marketing Authorization, which is required by D&C Rules, to obtain permission.

This application should be sent to the Drugs Controller General (India), Central Drugs Standard Control Organization, Directorate General of Health Services, Ministry of Health and Family Welfare, Government of India for assessment, together with the R&D data, CMC data, Non-Clinical & Clinical Data.

Herbal medicinal products are included in the European legal framework for medicinal products to ensure their quality, efficacy, and safety, Because of the unique characteristics of these drugs, a streamlined approach for ensuring pharmaceutical quality was developed, while maintaining the safety and efficacy standards set forth in the marketing authorization obtained.

A European Union herbal monograph contains all of the information needed to utilise a medical product that contains a specific herbal component or preparation.
