Pharmaceutical Manufacturing

Medicine manufacturing or pharmaceutical manufacturing is a process of research and development of medicinal products. It is solely aimed at providing life-changing and life-saving health products. The onus has always been on producing medicines that have zero side effects.

The pharmaceutical industry in the US has gained far-reaching influence and acclaim, for its cutting-edge research and development in this space. This is driven by the fact that a high volume of its revenue is siphoned to research and development activities.

The R&D process is complicated, multistage and with high permutations and combination. There are two main stages, called the primary and secondary stage. The primary stage is concerned with the manufacture of the drug, and the secondary stage is concerned with the viability and safety of the application of the drug.

Thousands of compounds are tested in combination over a period of time. The results are compared and contrasted to find compounds that promote prevention, cure, alleviation or any other medicinal benefit of a disease, ailment, illness etc. This is no easy task. To aid this, are state-of-the-art pharmaceutical and medical equipment.

Pharmaceutical products come in different sizes, shapes, and combination. Some of the notable pharmaceutical product forms are capsules, tonics, ointments, dispensers, tablets, and so on.

New research is being undertaken to bring in new drugs. Technological evolution has made it easier to study the behavior of animal and plant cells in controlled environments. There has also been substantial ground made in the field of regenerative therapy, which deals with regeneration of organs, and tissues.

The civilized world has seen so many ailments and diseases that have recently erupted, or have been around for centuries. Custodians and patrons of the pharmaceutical industry always abide by the rule of pro-action and not reaction. It has always been difficult to predict variations of diseases, and come up with a fast responsive approach of delivering life-saving medical products.

Drug design is an innovative methodology of finding new drugs or medicines based on bio-molecular data. In other words, drugs are essentially complementary molecules of a bio-molecule, and exhibit the same functions of a bio-molecule. A bio-molecule is produced naturally by living organisms. They could be lipids, vitamins, hormones, monosaccharide, DNA, RNA etc.

The intent of drug design is to enable drug molecules to bind successfully to bio-molecular targets. This means it is essentially the design and development of ligands. Ligands are substances with the ability to bind to bio-molecules. The binding is not permanent, and it can be dissociated. This means a drug design effort has to factor-in binding properties of a ligand. Strong binding of a ligand to a target bio-molecule is because of intermolecular forces. Binding affinity is not an indicator for the efficacy of the ligand though. Based on the binding there are two types: selective and non-selective binding. Selective binding ligands only bind to select bio-molecules, whereas non-selective binding ligands bind to any type of bio-molecule.

What was discussed till now is a ligand based approach to drug design. There is another approach to drug design called the structure-based approach. A three dimensional structural analysis is derived of a bio-molecule or a set of bio-molecules. Using this data, drug molecules are designed to combine with the bio-molecules. Special graphic software is used to aid this. The structural image is obtained by using crystallography techniques. X-rays are beamed into the target bio-molecule to get a graphical definition about the arrangement of atoms in it. Nuclear magnetic resonance spectroscopy (NMR) is another way to ascertain the structure of a bio-molecule.

These developments to map the structure of bio-molecules have lead to better drug design. It has enabled pharmaceutical manufacturers to better understand the nuances of providing receptor-specific ligands. Now the situation has progressed to add computer-aided processes as well. There have been huge strides made in the field of molecular mechanics that enable computational accuracy of drug-design fits with regards to ligands and bio-molecular receptors.

Nuclear Medicine

Nuclear medicine is a branch of traditional or mainstream health medicine. It deals with the analysis of a disease through medical imaging using radionuclides. Radionuclides are atoms with unstable nuclei. Radionuclides undergo radioactive decay. While doing so they exhibit gamma rays.

Nuclear medicine uses pharmaceutical compounds used in conventional health medicine with radionuclides. This combination is called radio-pharmaceuticals. Radio-pharmaceuticals fall under the umbrella of radio-pharmacology that deals with the study, evolution and application of radio-pharmaceutical health medicine.

Nuclear medicine has now progressed into a specialized branch of health medicine. Gamma cameras were used in the first advent of nuclear medicine as early as 1950s. A gamma camera is also known as an anger camera. The pattern now practiced is the use of radioactive chemicals in the body, to image a part of the body. They are inducted into the body orally or through an intravenous injection. They can also be administered by way of inhalation. Radioactive chemicals are nothing but radio-pharmaceuticals. They are called isotopes. They are prepared in such a way, that they localize at the target location. The tissue or organs absorb or accommodate the radio-pharmaceuticals. This area then exhibits or gives out gamma rays. The gamma rays are captured by a gamma camera. The gamma camera has a special functionality that converts the emitted gamma ray to an electric signal.

A computer processes the electric signal and an image is created. Iodine and technetium are the usually used substances for nuclear medicine. Modern computers aid nuclear medicine just as they aid the advancement of conventional health medicine. Radiologists and nuclear medicine physicians usually perform the imaging and analysis activities.

Nuclear medicine is a type of diagnostic health medicine that plays an excellent role in diagnosis and analysis of complex, surgical situations in the body. In other words, where normal radiology lacks the penetration and perfection of diagnosis, nuclear medicine has its calling. It can also be comparatively less expensive. Nuclear medicine is used extensively in bone scans, heart scans, liver scans, and a lot many more areas.

Pharmaceutical Nanotechnology

Nanotechnology is manipulation of matter at the atomic level. This means that measurement levels come down to nanometers. A nanometer is one billionth of a meter. Nanotechnology deals with matter at a size of 1 to hundred nanometers. Nanotechnology helps achieve molecular mechanics, and is instrumental in aligning or re-aligning molecules of matter in a desired manner. It holds a lot of importance in health medicine.

Pharmaceutics and health medicine rely on the efficacy of drugs. Huge drug molecules pose the problem of penetration and permeability. Nanotechnology is an answer to that. This need to involve minuscule-manufacturing has given rise to pharmaceutical nanotechnology manufacturing. Pharmaceutical nanotechnology in health medicine can improve the solubility; reduce the side effects, and enhance better dispensation of medicinal products. It will increase the therapeutic healing process manifold.

Pharmaceutical nanotechnology can provided more directed and accurate treatment of health conditions. Due to the reduced surface-area of drug molecules, they can be better managed; will consume less external and internal energy, and offer increased imaging capabilities for the most optimum diagnosis and treatment.

In health medicine, it has its applications in various spheres. It increases the absorption of the drug in the body. This is called bio-availability. Many times, orally administered health medicine will fail to be absorbed completely. It can also be due to first-pass effect. First-pass effect is the decrease in the concentration of an orally administered health medicine, before it arrives at the systematic circulation system of the body. When drugs or health medicine are swallowed, it most often than not loses a lot of its concentration in the digestive system. Now with pharmaceutical nanotechnology, orally administered health medicine will retain its concentration, because of its negligible surface area.

Pharmaceutical nanotechnology will have the greatest impact in cancer treatment. It can be used in chemotherapy to target only malignant cells, and leave normal cells alone. In the conventional chemotherapy being done now, both malignant and normal cells are being damaged, leaving the patient fatally fatigued.
