Farmaceutische equivalenten

Pharmaceutical equivalents deliver the same amounts of active pharmaceutical ingredients or APIs over a similar dosing period.

Generic drugs are pharmaceutically equivalent to the reference drug when they contain the same amount of active pharmaceutical ingredient and have the same dosage form.

They must adhere to compendial standards for potency, content uniformity, disintegration time, and dissolution rate.

Drug content variations are permitted in modified-release dosage forms if the delivered drug amount remains identical to that of the innovator product.

However, different salt forms or prodrugs of the same API are not considered pharmaceutical equivalents under the FDA's definition.

Pharmaceutically equivalent products may contain different excipients or allowable impurities and may also vary in shape, packaging, labeling, and physical attributes.

API characteristics like particle size, polymorphism, purity, stability, and stereochemistry influence pharmaceutical equivalence.

Drug delivery systems, the dosage form’s physical attributes, sterility, overage, and manufacturing processes also affect its equivalence.
