Pharmaceutical Lab Testing: from API Inspection to QA

Pharmaceuticals are developed, designed, and commonly manufactured in laboratory settings. Laboratory testing is an essential need in almost every stage of pharmaceutical production and R&D, from the inspection of incoming raw materials to dosage-form quality control (QC).

Along with analyzing the actual product and its ingredients, pharmaceutical laboratory testing is frequently performed to identify manufacturing problems that could present harm to human health.

This article from Jordi Labs examines the most common types of pharmaceutical laboratory testing, from manufacturing quality assurance (QA) to the inspection of bioactive pharmaceutical ingredients (APIs).

Pharmaceutical lab testing of APIs

After being introduced into the body, drugs produce a pharmacological effect as a result of the unique mechanism of action of the product’s biologically active components. Tablets and pills are sometimes known by their API.

For example, the bioactive constituent of aspirin is acetylsalicylic acid, which is widely known as aspirin. However, patients can find it difficult to identify the API in their medication as drugs are more commonly marketed with brand names.

Analyzing incoming APIs in a pharmaceutical laboratory is crucial for complying with international regulatory requirements in the healthcare and pharma industries. The techniques for analyzing these components vary significantly, given the broad range of physical and chemical forms that APIs can take.

High-resolution mass spectrometry and gas and liquid chromatography techniques are among the most important methods for API impurity/purity and toxicology screening.

Pharmaceutical lab testing of excipients

Excipient materials are usually manufactured alongside APIs to increase thermodynamic stability, extend shelf-lives, control drug release rates, and control pharmacokinetics.

The absorption abilities of dosage form pharmaceuticals can establish the rate at which they travel from dissolution in vivo into the bloodstream, where they begin to exhibit pharmacological effects.

While technically inactive, excipients play an essential role in dosage-form pharmaceuticals, frequently making up the majority of the end product. Pharmaceutical laboratory testing is performed to evaluate how excipients influence the process of assimilation in APIs to enhance recipes for preferred therapeutic effects.

Certain excipients can be included to slow dissolution for drugs where a fast release could harm delicate tissues and produce internal irritation. Others are designed to provide efficient relief from symptoms by disintegrating quickly.

GPC is frequently employed to analyze polymeric excipients as the rate of drug release is often directly related to the molecular weight of the polymer. When it comes to excipient laboratory testing, the broad selection of freely available excipients (polymeric and small molecule) demands a flexible mindset.

Pharmaceutical lab testing of contact materials

The dosage form products and raw materials must be tested separately and together to ensure significant equivalence in new drug development research or to guarantee batch-to-batch consistency.

Further quality assurance and control must be performed on packaging materials and finished goods to guarantee that residues, particulates, leachables, and extractables that can contaminate products are eliminated from market circulation.

Tablet impurity characterization

Fourier-transform infrared spectroscopy microscopy (FTIR) with energy-dispersive X-ray spectroscopy scanning electron microscopy (SEM-EDS) are two of the main techniques for the identification of contaminants in pharmaceutical tablets.

These techniques offer information on chemical composition for both inorganic and organic impurities and help to rectify issues such as particulate identification or tablet discoloration.

Jordi Labs recently discussed the importance of characterizing particulates and residue in pharmaceuticals in further detail.
