Pharmaceutics and Novel Drug Delivery Systems

Targeted drug delivery is a kind of drug delivery, a method of delivering medication to a patient in a manner that increases the concentration only in particular area of the body. The goal of a targeted drug delivery system is to prolong, localize and have a safe drug interaction with the diseased tissue. The advantages of the this drug delivery are 1. reduction in the frequency of the dosages taken by the patient 2. have an uniform effect of the drug, 3.reduction of drug side-effects 4. reduce fluctuation in circulating drug levels 5.maintain the optimum plasma and tissue drug levels in the body. A small portion of the medication reaches the affected organ in Chemotherapy  and roughly 99% of the administered drug does not reach the tumor site.

The following criteria must be taken into consideration while designing a targeted drug delivery: the drug property,the route of drug delivery, the targeted site, disease and the side effects of drug. There are two kinds- active targeted drug delivery such as antibody medications and passive targeted drug deliver such as the enhanced permeability and retention effect.

Drug delivery is the action of administering a medication into the body for a therapeutic effect through various routes. Drug delivery technology modifies drug release profiles, pharmacokinetic parameters to improve product efficacy as well as patient convenience. Conventional routes cannot deliver compounds such as proteins, antibodies, vaccine and gene based drugs because these routes are susceptible to enzymatic degradation or cannot be absorbed into the systemic circulation efficiently due to large molecular size and charge issues.

Technologies include controlled needle-free devices, sustained, controlled transdermal delivery technology and penetration matrix technology for non-invasive delivery. Many innovative technologies for effective drug delivery have been developed that includes implants, nanotechnology, cell and peptide encapsulation, micro fabrication, chemical modification.

Biotechnology advances are leading to develop medications to target diseases more effectively and precisely.

Nanotechnology delivers drugs to targeted cells by nanoparticles. The overall drug consumption and side-effects are lowered significantly by depositing the active drug in the particular site and preventing administration of booster doses. Nanotechnology based devices are less invasive. They can be safely implanted inside the body as biochemical reaction times are much shorter.

The goal of drug delivery systems is to deliver medications to specific target parts of the body through a medium that can control the therapy’s administration. To achieve this goal, researchers are switching to advances in the worlds of micro- and nanotechnology.

The recent advances in the peptide,protein drug delivery systems are PEGylation and Depo-foam technology. Cell-penetrating peptides (CPPs) act as cargo carriers and constitute current medical research. CPPs to transport hydrophilic macromolecules into cells, thus, assist to execute biological functions. CPPs do not destroy the integrity of the cell membranes so they are considered more efficient and provide new avenues for research and applications in life sciences.

Needle-free drug delivery systems are novel ways to introduce various medicines to patients. PowderJect Pharmaceuticals one of the first companies to develop a needle-free technology for injecting powdered drugs into the skin. Needle free devices can take the form of power sprays, edible products, inhalers, and skin patches

Transdermal patches are user-friendly, convenient, painless and offer improved patient compliance.

Nano drug delivery systems such dendrimers, fullerence, nano pores, nanotubes, nano shells, quantum dots, , nanovaccines, revolutionized drug delivery systems. Thus nanomaterial can be used for strategic development of new drug delivery systems and reformulate existing.

Anti-cancer drugs such as loperamide and doxorubicin bound to nanomaterial have been shown to cross the blood-brain barrier.

Nanoparticles are generally less than 100 nm in dimension and consist of different biodegradable materials such as natural or synthetic polymers, lipids, or metals. Nanoparticles are taken up by cells more efficiently than larger micromolecules. Nanoparticles have high surface area to volume ratio thus allowing many functional groups for attachement. The small size of nanoparticles allows them to accumulate at sites.    

Nano particles can (1) enhance the efficacy and minimize adverse reactions associated with drugs; (2) enable new classes innovations; and (3) encourage the re-investigation of pharmaceutically suboptimal but biologically active new molecules that were previously considered undevelopable.

Nanoparticles are used in drug delivery to improve the uptake of poorly soluble drugs.

As per BCC Research the global market for nanoparticles in the life science forecast to grow to more than $79.8 billion by 2019, to register a healthy compound annual growth rate (CAGR) of 22%.

Innovative, non-invasive delivery includes improvement of patient acceptability and compliance, improvement in public safety, decrease of administration costs and a reduction of adverse effects. Enzyme degradation, acid degradation, hydrolysis and low permeability of intestinal epithelium in the GI tract surfaces make oral administration a non-viable delivery method. Proteins are administered parenterally as oral administration cause low bioavailability in the GI tract. It has become a challenge to achieve consistent and adequate bioavailability levels for oral administration.

Economic and financial barriers also stand in the way of implementing nano medicine. The limited availability of reimbursement by public and private health insurers for expensive new diagnostic tests has emerged as a major impediment to the deployment of personalized medicine. Nanoproducts encounter even greater hurdles because of their costs and complexity,  cytotoxicity of nanoparticles are  main concern of future research.

Advances in medical science, research and development (R&D) are changing the dynamics of the life science industry which includes pharmaceuticals and healthcare. The development of new drugs enhances the development of different drug delivery systems, which is further driven by innovation in technology, R&D and scientific advancements. Advances in understanding human diseases and medical treatments are opening new opportunities in the pharma industry. A better technology for drug administration or delivery is in demand now.

One of the biggest challenges in the drug discovery and development for CNS disorders is to achieve significant blood–brain barrier (BBB) penetration.

Many drugs do not have high lipid solubility, low molecular size and positive charge to traverse BBB. The issues associated with the blood–brain barrier are 1. The drug produced allows only a small portion to pass through the barrier 2. Binding to other proteins in the body makes the drug ineffective or pass through the barrier with that adhered protein. 3. The presence of enzymes in the brain that could render the drug inactive. All of these problems must be addressed to deliver effective drugs to the brain.

Developed strategies enhance the capacity of drug to cross the BBB by modifying the drug or by coupling it to a vector for receptor-mediated or adsorption-mediated transcytosis.

Compounds using BBB technology in the clinical development would reach approximately eight by 2019. The global market for BBB technologies was valued at $38.7 million in 2014. The market is expected to grow to $471.5 million by 2019, and register a tremendous 64.9% CAGR from 2014 through 2019.

It is defined as the method by which a drug is delivered can have a significant effect on its efficacy i.e. the drug become more efficacient in order to minimize drug degradation, adverse effects and to increase the bioavailability to produce betterresult. NDDS covers various aspects like pharmacokinetics & pharmacodynamics, non-specific toxicity, immunogenicity, bio recognition, and drug’s efficacy based on preferable approaches that include polymer science, pharmaceutical technology, dispensing pharmacy, packaging technology, bio conjugate chemistry, and molecular biology.

A drug carrier enhances the selectivity, effectiveness and safety of drug administration. Drug carriers are mainly used to control the release of a drug into systemic circulation. This can be accomplished either by slow release of the drug over a long period of time (typically diffusion) or by triggering the release at the  target by stimulus, which include pH changes, application of heat and activation by light. Drug carriers improve the bioavailability of poorly water soluble drugs or membrane permeable drugs.

An ideal drug delivery vehicle must be non-toxic, non-immunogenic, biocompatible and  biodegradable Different methods of drug attachment to the carriers include adsorption, integration, encapsulation, and covalent bonding.

Peptides and proteins have more potential as drug delivery systems. Compared with the small size drugs, peptides and proteins can be highly selective as they have multiple contact points with their target. Increased selectivity results in decreased side effects and toxicity. Peptides can be designed to target a broad range of molecules and provide opportunities in oncology, infectious disease and endocrinology fields. The market for peptide and protein drugs is estimated to be greater than US$40 billion/year, or 10% of the pharmaceutical market .At present there are over 100 approved peptide-based drugs in the market. The pharmaceutical scientists have approaches to develop the protein and peptide delivery formulations by noninvasive routes.

Gene therapy is defined as incorporation of genetic material i.e, DNA or RNA, in the cellular gene regulation system, either to correct the expression of a malfunctioning gene or to modulate the cellular functions. Nanotechnology advances gave rise to the development of nanoparticle-DNA delivery systems. Gene delivery is an important part of genome evolution. Gene delivery utilizes non-immunogenic vectors capable of cell specificity that can deliver an adequate amount of transgene expression to cause the desired effect. Gene therapy advanceshave enabled a variety of new methods and gene targets to be identified for possible applications. Gene delivery has been utilized to generate a hybrid biosynthetic vector to deliver a possible vaccine.

Pharmacokinetics describes how the medicament gets influenced after administration, followed by absorption, distribution, metabolism mechanisms and excretion of the drug substance. Pharmacokinetic knowledge assists prescribers to adjust dosage accurately and precisely. Clinical kinetics is defined as the applications of pharmacokinetic principles in the safe and adequate management of individual patient. Toxic pharmacokinetics is defined as the applications of pharmacokinetic principles to the designation, behaviour and interpretation of drug safety evaluation studies.

Pharmacodynamics describes biochemical, physiological, and molecular effects of drugs on the body and involves receptor binding (including receptor sensitivity), post receptor effects, and chemical reactions. The pharmacological response depends on the drug binding to its target. The effect of drug presence at the site of action is measured by drug-receptor binding.

Drug discovery is the process in which potential new medicines are recognized and comprises an effective range of scientific disciplines, including biology, chemistry and pharmacology. The integration of pharmacodynamics and pharmacokinetic parameters in non-clinical pharmacology studies plays a key role in drug discovery for efficacy and safety assessment, in particular for translation from the non-clinical to clinical field and process of drug discovery include  the identification , synthesis, characterization, screening, and assays for therapeutic efficiency and modern drug discovery involves the identification of screening areas, medicinal chemistry and optimization of those areas to increase the affinity, selectivity, efficacy/potency, metabolic stability, and oral bioavailability.

FDA provides scientific and regulatory advice to bring new therapies to market. In 2018, FDA has approved 43 new drugs which are currently in the market. Every year, CDER approves series of new drugs and biological products. The availability of new drugs represents new treatment options for patients and advances in health care. Some of these are often innovative new products that never before have been used in clinical practice. A new chemical entity (NCE) is a drug that contains no active molecule that has been approved by the FDA in any other application submitted under the Federal Food, Drug, and Cosmetic Act.

Pharmacovigilance and Risk Management comprises set of pharmacovigilance activities designed to identify, characterise, prevent or minimize risks related to medicinal products which  includes the assessment of the effectiveness of their clinical interventions and combination therapies.

Pre-formulation studies are important for various phases of clinical trials. Pre- formulation studies act as the first step as well as the scientific foundation for formulation design and development. These studies provide guidance in selection of drug, excipients, to determine chemical composition, physical pattern and assist in adjustment of pharmacokinetic profiles. Improving public safety measures and intensifying product quality, safety, accuracy are the other characteristics.

The main purpose of pre-formulation studies is to improve compatibility with the other ingredients and develop stable, potent and safe dosage form. Physico-chemical parameters, drug solubility studies, partition coefficient, dissolution kinetics, polymorphism and stability profiles play a significant role in pre-formulation studies. These studies furnish the information regarding the degradation process, toxic effects and adverse conditions. So Pre-formulation is an interdisciplinary basis in drug development.

Formulation is defined as the process in which different chemical substances including the active ingredient are compounded to produce a final dosage form. Developed formulations should be stable, safe and acceptable to the patient.

Vaccine is a material that induces an immunologically mediated resistance to a disease. Vaccines are generally composed of killed or attenuated organisms or subunits of organisms or DNA encoding antigenic proteins of pathogens. Vaccines though exceptionally selective and specific in reacting with antibodies often fail to show reactions in circumstances such as shifts in epitopic identification center of antibody and are poorly immunogenic. These vaccines require boosting with agents called adjuvants in order to induce an effective immunity. Adjuvants potentiate the immunostimulatory property of the antigen and are non-immunogenic, nontoxic, and biodegradable in nature.

Conventional immunization regimen involves prime doses and booster doses. Immunization failed as patients neglect the booster doses. These reasons led the development of new generation of prophylactic and therapeutic vaccines to promote effective immunization. Vaccines allow for the incorporation of doses of antigens so that booster doses are no longer needed as antigens are released slowly in a controlled manner. Attempts are being made to deliver vaccines through carriers as they control the spatial and temporal movement of antigens to immune system thus leading to their sustained release and site targeting. Carrier systems such as liposomes, microspheres, nanoparticles, dendrimers, micelles and ISCOMs are being investigated and developed as vaccine delivery systems
