Read on to discover all you need to know about bacteriostatic water for injections!
Bacteriostatic water is a sterile and non-pyrogenic solution designed for use in parenteral injections. It is made of sterile water and 0.9% benzyl alcohol, a natural preservative that halts the growth of bacteria to combat contamination. Its primary use is to dilute or dissolve substances for aqueous injection via intramuscular, intradermal, subcutaneous, and intravenous routes. With an average pH of 5.7 (4.5-7), it is manufactured and sold generically as Bacteriostatic Water for Injections, USP [1, 2].
The preservative in bacteriostatic water inhibits bacterial growth without killing bacteria. Therefore, the aseptic technique is required when handling this solvent to maintain its sterility. Aseptic measures include the use of sterile needles when accessing the solution, as well as proper storage.
When handled accordingly, bacteriostatic water may be stored and safely used within 28 days of opening. After 28 days, the benzyl alcohol is subject to degradation, increasing the likelihood of contamination. However, unopened vials of bacteriostatic water can remain sterile for several years [1, 2].
As a sanitary and convenient solvent, bacteriostatic water is favored among researchers and medical practitioners. Now, we will dive into its primary applications and the best handling practices as proscribed by experts.
Bacteriostatic water serves to dissolve or dilute substances that require aqueous suspension for delivery via injection. Due to its organic preservative content (0.9% benzyl alcohol), solutions made with bacteriostatic water can be used for multiple doses without contamination [1].
When handled following the aseptic technique, a vial of bacteriostatic water remains sterile for approximately four weeks after opening. Solutions made with bacteriostatic water accordingly have extended shelf lives and a reduced risk of contamination in comparison to other solvents. Because the injection of contaminants increases the likelihood of infection, the use of bacteriostatic water is considered a prime safety measure in clinical settings [1].
Beyond safety and convenience, the pharmacodynamics of this solvent add to its popularity among researchers and medical practitioners. It provides great solubility for most substances and interacts minimally with the majority of medications. Plus, it maintains a favorable safety profile when correctly handled [1].
The specific applications of bacteriostatic water are [1]:
Qualified researchers often use bacteriostatic water for the reconstitution of experimental substances, namely [3]:
It is suited to these injection routes, contingent on the solute, the condition of the subject, and target rates of diffusion and metabolization [1]:
Handlers are advised to follow all manufacturer indications and precautions. Bacteriostatic water is contraindicated for use in certain populations, including neonates and subjects with benzyl alcohol allergies.
Further, it is not safe for use in spinal injections or administration without a solvent, respectively linked with neurotoxicity and hemolysis. Adverse reactions are uncommon and may include fever, injection site irritation, or venous thrombosis. If these occur, discontinue use and seek medical attention [4, 5, 6].
Qualified researchers most often choose bacteriostatic water as their preferred sterile solvent when working with various therapeutic substances for injection. In this capacity, the primary experimental solutes are peptides and hormones.
Here, we will explore why bacteriostatic water is best suited to injecting these beneficial compounds, as well as guidelines for proper use.
Peptide therapeutics is an emerging pharmaceutical field that involves the administration of peptides and peptide-based drugs in a range of clinical contexts. Studies have shown numerous benefits of synthetic peptides, including the treatment of inflammatory and cardiovascular diseases, as well as cognitive health. Peptides in most cases present positive safety profiles and multiple therapeutic outcomes [7].
The primary mode of peptide delivery is via injection. This is the most bioavailable route due to the relatively low stability of most peptides in gastric juices and nasal mucosa. Peptides for injection are typically sold in the form of lyophilized powder for safe storage and transport. As such, they are to be reconstituted using sterile solvents before injection [8, 9].
In most cases, bacteriostatic water is the optimal solvent when reconstituting peptides for injection. The pharmacodynamics of the organic preservative agent provide optimal solubility without damage to the peptides, as well as reduced risk of contamination. Solutions made with bacteriostatic water can be accessed for multiple doses to facilitate various courses of therapy. Aseptic handling methods and proper storage procedures must be used [10].
In rare cases, a stronger solvent may be required to dissolve a peptide powder. While there are several other solvents to choose from, specialists recommend against sodium chloride water when reconstituting peptides for injection due to its tendency to create residues [10].
The standard method for reconstituting lyophilized peptides and other compounds intended for aqueous injection is the following [11]:
an growth hormone (HGH), also called somatotropin, is produced in the pituitary gland. This hormone is vital to healthy growth and development from birth and is of ongoing importance in numerous physiological functions through adulthood. These include the regulation of cardiometabolic processes, as well as physical composition and bone density [12, 13].
Low levels of HGH are associated with many unpleasant symptoms, such as fatigue, excess body fat, muscle weakness, and cardiovascular risk. Pathologically low HGH levels may be diagnosed as growth hormone deficiency (GHD), known to cause impaired growth in children and various problems into adulthood. Hormone replacement therapy using exogenous HGH is a common method to address low levels of this hormone. HGH injections have many therapeutic outcomes, such as improved physical performance and body composition, as well as the treatment of GHD in diverse populations [12, 13].
For use in hormone therapy, HGH is available with a prescription and is occasionally available in lyophilized powder form, requiring reconstitution for aqueous injection. Medical practitioners recommend bacteriostatic water as the best solvent for HGH injections due to its reduced risk of contamination and the convenience of multi-dose vials. Having ready-made solutions on hand is advantageous to keep up with the daily dosage requirements. As with most peptides, bacteriostatic water also provides great solubility without compromising the purity of the HGH molecules [14].
The procedure for HGH reconstitution with bacteriostatic water mirrors the process described above. HGH solutions are delivered via subcutaneous injection into fatty areas of the body, such as the waist, abdomen, and thigh. For proper storage measures, consult the accompanying product literature. HGH is not to be used without a prescription and must be handled using the aseptic technique [14].
Human Chorionic Gonadotropin (HCG) is also popular in hormone therapies. The polypeptide hormone affects fertility in both men and women. It is produced in the human placenta and is nearly identical to the pituitary luteinizing hormone (LH). In males, it has an androgenic effect, while in females it is involved in the ovulatory process as well as implantation [15, 16, 17].
HCG therapy entails the subcutaneous injection of exogenous HCG to increase male and female fertility. It is also indicated in the treatment of male hypogonadism and prepubertal hormonal imbalance, commonly prescribed as a complement to testosterone replacement therapy (TRT). While ongoing research suggests further benefits, these are the uses currently under the approval of the US Food and Drug Administration (FDA). HCG is strictly available on a prescription basis [15].
Supplied in lyophilized powder form, HCG must be reconstituted before injection. HCG prescriptions often include bacteriostatic water , the preferred solvent due to its safety and provision of multi-dose vials. The correct method of HCG reconstitution is identical to the process described above. For exact storage and dosage guidelines, always consult the manufacturer's indications. Use only as directed by medical professionals [15].
While bacteriostatic water may sometimes be available under prescription for medical use, qualified researchers can legally purchase it over the counter for educational purposes. Prescription Bacteriostatic Water for Injection, USP is strictly for use in parenteral injections as directed by a doctor. In all cases, it should be purchased from a legitimate source and handled using aseptic techniques according to safety guidelines [1].
When purchased for investigational purposes, bacteriostatic water is strictly to be handled by qualified researchers. These individuals must have ample experience in the topic of study, deep knowledge of all technical and safety procedures, as well as familiarity with the latest relevant peer-reviewed literature. Great care and attention to detail should be applied when handling all substances. Handlers must be able to analyze data sets and modify research methods accordingly.
A legitimate retailer of bacteriostatic water for research purposes should adhere to these measures:
When purchased by qualified individuals from trusted retailers, bacteriostatic water is safely available for research use.
Bacteriostatic water does not require refrigeration and should be stored at 60-80 degrees Fahrenheit away from direct light. A cabinet or closet is ideal. Handlers should be careful not to place items on top of bacteriostatic water vials. Damage to the vial could compromise the contents and lead to contamination. The storage requirements are subject to change when bacteriostatic water is mixed with a solute. Researchers should store reconstituted solutions according to manufacturer guidelines. Whether sealed or opened, bacteriostatic water should never be used past the expiration date [1].
Bacteriostatic water and sterile water are both classed as sterile solutions for use in injections. Like bacteriostatic water, sterile water is a popular solvent in research and medical contexts. While these substances are related, they differ in some important regards. Here, we will discuss these points of similarity and difference and, most importantly, the reasons why these solvents are not considered interchangeable [1, 18].
Sterile water is made of aseptic water that has been distilled and purified according to certain procedures. It has no preservative additives and an average pH of 5.5 (5.0-7.0). Available as a medical solvent or diluent under the label Sterile Water for Injection, USP, it is intended for parenteral injections. Because it is preservative-free, sterile water cannot be safely stored after opening. Therefore, it is marketed in single-use vials [18].
The notable similarities between bacteriostatic water and sterile water are as follows [1, 18]:
Here are the key differences between bacteriostatic water and sterile water [1, 18]:
This comparison illustrates the superiority of bacteriostatic water overall. It is longer-lasting, more sanitary, and altogether more suitable for use in therapeutic injections unless otherwise indicated by a medical professional.
For the safe reconstitution of peptides and hormones, it is important to have sterile syringes and alcohol wipes in addition to high-quality bacteriostatic water. Researchers may be unsure of where to source the best bacteriostatic water and accompanying items.
