Key services


Pharmaceutical Development

SRC offers a full spectrum of pharmaceutical development services from pre-clinical stage through early-phase & late-phase clinical studies to commercial manufacturing. Our mission is to provide on-time delivery of superior quality formulations in the right quantities at the best price to our customers. From early phase development to ANDA formulations, we bring decades of global expertise and state-of-the art facilities to meet our client specifications with punctuality, precision and rigor.


Formulation & Analytical Development

Formulation Development
Our expertise in formulation development extends to the development of all conventional dosage forms. Our strategic alliances broaden the scope to consider many Novel Drug Delivery Systems (NDDS), including transdermal & liposomal delivery systems. We consider multiple approaches to improve the bioavailability of drugs. We are constantly expanding our capabilities, including in our repertoire additional modules and suites to develop a CACO-2 cell membrane permeability study laboratory.

Collectively, we have the experience to formulate oral solids, dermatologicals, ophthalmic suspensions and ointments, expertise in improving delivery of poorly soluble/ permeable drugs and the capability to screen potentially innovative drugs based on pharmacokinetic properties. We possess pelletization, drug-layering, particle-coating and other technologies to achieve extended release profiles for tablets or capsules.

Analytical Development
Our analytical development services include assay and RS method development and validation, dissolution method development and validation, stability studies as per ICH guidelines, polymorphic form characterization (DSC/TGA/XRD/Microscopy), cleaning validation studies and HPLC to UPLC method conversions.

Semler Research Center recognizes pre-formulation as a critical phase in the drug development cycle and has developed a basket of services that ranges from scientifically justified experiments for salt selection to establishing chemical specifications for the active pharmaceutical ingredient (API).

Physicochemical tests conducted during discovery and lead optimization using advanced analytical techniques – DSC/TGA/XRD and so on - enable rational decisions for compound, salt or polymorph selection that maximize the probability of compound success and are essential to the establishment of a sound intellectual property position.

Upon thorough understanding of the physico-chemical properties of the API, the development routine will include characterization of API – excipient mixtures, materials of construction effects, process variables that affect API or formulation attributes.
