| Summary: | Recently, controlled release (CR) pharmaceutical products have become a very useful tool in medical practice, offering a wide range of actual and perceived advantages to the patient. A CR product requires numerous considerations, like drugs suitable for CR formulations, techniques of fabrication and evaluation, factors affecting bioavailability of the parent drug, before it can actually be claimed to provide the purported benefits. Such complex considerations fall under the domain of pharmaceutical experts and clinicians, naturally, are not sufficiently aware and updated about these products and their biological consequences. Various CR formulations used in neurological practice are discussed in the present review. The clinical studies of the conventional and CR dosage form of the drugs used in neurology practice reflect the advantages of prescribing CR formulations over the conventional dosage forms.
