PARENTERAL PREPARATIONS

PARENTERAL PREPARATIONS INTRODUCTION Parenteral (Gk para enteron beside the intestine) dosage forms differ from all other drug dosage forms because they are injected directly into body tissue through the primary protective systems of the human body the skin and mucous membranes

What are the different routes of parenteral administration?
While many routes of parenteral administration are available, all of which bypass the intestinal tract, the intravenous, intramuscular, and subcutaneous routes of administration are the most commonly used. Table 1-1 lists various routes and locations of delivery of parenteral admin-istration.
Why is a standardized method important for parenteral medication administration?
It is important to follow a standardized method for parenteral medication administration. Agency policies on medication preparation, administration, and documentation may vary, so it is important to receive agency training on using their medication system to avoid errors.
What is a parenteral medication?
18.1. ADMINISTRATION OF PARENTERAL MEDICATIONS INTRODUCTION Administering medication by the parenteral route is defined as medications placed into the tissues and the circulatory system by injection. There are several reasons why medications may be prescribed via the parenteral route.
How to prepare a parenteral solution?
Preparation of Solution:- The various ingredients of the formulation of parental preparations are weighed and collected in the preparation room. the raw materials required in the preparation of parenteral products should be pure. water for injection free from pyrogens and microorganisms are used in preparation of parenteral products.

Objectives

This chapter provides an overview of the development of injectable (parenteral) drug products. Injectable drug products are relatively specialized and diverse, depending on both the location and type of disease to be treated in a patient. Developing an optimized formulation around a certain type of product will determine not only whether or not the

Terms

Buffer Capacity: the strength of a buffer system; the amount of acid or base that can be added before the solution pH shifts Buffer System: a weak acid and its conjugate salt that prevents the pH from shifting in a solution Emulsion: in colloid chemistry, a suspension of one liquid (oil) in another (aqueous) Endotoxin (Pyrogen): a lipopolysaccharid

Basic theory

Parenteral (para enteron—beside the intestine) administration is the introduction into the body of nutrition, medications, or other substances other than by the alimentary canal. Unlike taking medications orally or rectally, introducing a drug into the body by parenteral administration poses far greater risk since the body’s natural defenses are by

Injectable Suspensions

Suspensions are products where the active ingredient is extremely insoluble in the solution used to deliver it (the vehicle). Suspensions are formulated as such so when they are injected to a precise location, the drug crystals slowly dissolve, resulting in a controlled, slow release of the drug to the surrounding capillaries where it is absorbed i

Structured vehicle

The structured vehicle approach is based on the viscosity of the suspending solution (vehicle) and how the viscosity changes with shear force (shaking). The study of viscosity (Rheology) is an involved science, and liquids behave differently depending on their characteristics. Many fluids follow what is known as Newtonian Flow, which states that

Routes of Administration

A parenteral product may be administered via several different routes based on different criteria, including onset of action, bioavailability, and delayed release. The most common routes of administration are: subcutaneous – under the skin intramuscular – into a muscle intravenous – into a vein either by bolus (directly into a vein) or infusion (di

Specifications

Injectable drug products, like other drug products, must meet certain specifications in order to be released for sale to the public. Unlike oral drugs (tablets, capsules, etc.), injectable drug products have additional specifications that must be met due to these products bypassing the body’s natural defenses against microorganisms. Mandatory attri

Introduction

Formulation of a stable, safe, and effective injectable drug product is a sizable, challenging task involving many scientific disciplines and encompassing years of research and development. Once a drug is discovered and the first patent is filed, the company holding the patent has 17 years of market exclusivity for the drug before generic drug comp

Pre-formulation assessment

The pre-formulation assessment is an information gathering process to ensure that all of the required information is in place to begin the pre-formulation development studies. Having all of this information in place before starting pre-formulation development studies saves the development scientist both time and effort. Much of the information need

Pre-formulation development

The pre-formulation studies are designed essentially to find the conditions in which the molecule is most stable. Once these conditions are understood, the goal of the formulation development studies is to achieve these conditions through either the addition of excipients or how the product is processed (i.e., lyophilization). Pre-formulation devel

Solubility

The solubility of the drug can be a challenge for the development scientist. In some cases a bulk drug simply floats on top of the water used to dissolve it. In this case, solubility studies must be conducted. There are several ways to enhance the solubility of poorly soluble compounds; when doing so, the following questions should be addressed: Ca

Formulation development

The goal of the formulation development work is to establish the optimal conditions determined in the pre-formulation development studies. These conditions are achieved through procedures such as the addition of excipients, the control of oxygen, and the control of hydrolysis (through lyophilization). Additional information regarding the drug produ

Antioxidants, stabilizers, surfactants, and bulking agents

Occasionally additional steps must be taken to help stabilize unstable products. If the pre-formulation studies were performed correctly, the information regarding the damaging effects of factors such as light, temperature, water, and oxygen should all be known prior to starting the formulation development studies. If a drug is shown to be suscepti

Accelerated Stability Studies

During both the pre-formulation and formulation development studies, accelerated stability studies are conducted to determine the effects that different factors, such as excipients and processing, have on both the short- and long-term stability of the drug product. Typically formulations are prepared with variations, including pH, stabilizer, buffe

Process compatibility and scale-up

Once the final formulation has been developed, transferring the formulation, and requirements for filling and freeze-drying, to a manufacturing facility must be performed to ensure that the product can be made flawlessly while meeting the same release specifications that were established during the development studies. biomanufacturing.org

Scale-Up

Once the formulation is developed; the process compatibility studies are complete; and the batch record has been written and approved, the product is ready to be scaled up from a lab batch to a large batch prepared in production. This can be either a fairly simple process for small-molecule, water-based formulations or a relatively complex process
