Quagen Promethazine Hydrochloride And Codeine Phosphate Oral solution

In the landscape of pharmaceutical research, precision and reliability are paramount. For professionals seeking to study specific antitussive and antihistamine combinations, the Quagen Promethazine Hydrochloride And Codeine Phosphate Oral solution represents a subject of significant interest. This formulation, a prescription-grade combination therapy, offers a controlled and consistent medium for investigational purposes. At Psychedelic Hive, we connect you to the highest-quality research materials, ensuring your studies are built on a foundation of authenticity.

What Is This Product?

The Quagen Promethazine Hydrochloride And Codeine Phosphate Oral solution is a pharmaceutically manufactured combination product. Each 5 mL of this purple, raspberry-flavored syrup contains two primary active pharmaceutical ingredients (APIs): 6.25 mg of Promethazine Hydrochloride and 10 mg of Codeine Phosphate . Marketed by Quagen Pharmaceuticals LLC, this solution is classified under the DEA as a Schedule V (CV) controlled substance, indicating it has a recognized medical use but also a potential for abuse, which is a critical data point for researchers studying addiction medicine or controlled substance protocols .

How It Works in a Research Context

For researchers, understanding the pharmacodynamics of this solution is key.

• Codeine Phosphate is an opioid agonist. It acts on the mu-opioid receptors in the brain. In a clinical setting, it is utilized for its analgesic and cough-suppressant effects by depressing the cough reflex in the medulla . Researchers studying neurology or respiratory pharmacology often analyze this mechanism of action.

• Promethazine Hydrochloride is a phenothiazine derivative and first-generation antihistamine. It works by blocking histamine (H1) receptors and acting as a central nervous system (CNS) depressant . In this combination, it also serves to enhance the cough-suppressing effects of codeine while providing mild sedative properties .

Benefits and Advantages for Research

Utilizing the Quagen brand formulation provides distinct advantages over generic or unverified alternatives:

1. Consistency: As an FDA-approved Abbreviated New Drug Application (ANDA) product, every batch meets strict purity and dosage standards (10 mg/5 mL codeine phosphate and 6.25 mg/5 mL promethazine hydrochloride) .

2. Composition Integrity: The inclusion of specific inactive ingredients—such as anhydrous citric acid, D&C Red No. 33, FD&C Blue No. 1, alcohol, glycerin, and natural/artificial raspberry flavor—ensures the stability of the active moieties during the product’s shelf life .

3. Regulatory Benchmarking: Because it is a listed drug with the FDA (NDC: 70752-139-06 for 4 fl oz, and NDC: 70752-139-12 for 16 fl oz), research findings involving this compound can be benchmarked against established safety and efficacy data .

Longevity and Storage Life

To maintain the chemical integrity of this oral solution for research, strict storage protocols must be observed. Based on the official prescribing information, the solution should be stored at a controlled room temperature, between 20°C and 25°C (68°F to 77°F) . It is vital to protect the amber bottle from light to prevent photodegradation of the active ingredients. The bottles must be kept tightly closed and dispensed only in tight, light-resistant containers as defined by USP/NF standards . When stored correctly, the solution remains stable for the duration indicated on the manufacturer’s packaging, ensuring reliable long-term study parameters.

Usage Areas for Research Purposes

This product is strictly intended for research and analytical method development. Common areas of investigation include:

• Toxicology Studies: Analyzing the metabolic pathways of codeine and its conversion to morphine via CYP2D6 polymorphism .

• Respiratory Research: Studying the depressant effects of opioid-antihistamine combinations on the central nervous system .

• Analytical Chemistry: Developing HPLC or mass spectrometry methods for the detection of phenothiazines and opioids in biological matrices.

• Formulation Science: Evaluating the stability of syrup vehicles containing alcohol, sucrose, and sodium benzoate as preservatives .

Safety and Responsible Usage Considerations

At Psychedelic Hive, we advocate for the highest standards of laboratory safety. Researchers must be aware of the boxed warnings associated with this product. It is contraindicated in specific populations (e.g., pediatric patients under 12 years) due to the risk of life-threatening respiratory depression . Handling should be performed in a certified fume hood using personal protective equipment (PPE), as the product carries risks of addiction, abuse, and CNS depression .
