This formula also may be used when parenteral drug dosages are calculated. Join ResearchGate to find the people and research you need to help your work. Parenteral solutions are required to be isotonic with blood serum or other body fluids. The principal mechanism of action of memantine is believed to be the blockade of current flow through channels of N-methyl-d-aspartate (NMDA) receptors--a glutamate receptor subfamily broadly involved in brain function. Preformulation studies were reported to play a very important role to anticipate formulation problems and identify a logical path in the formulation of liquid, semisolid, and solid dosage forms.

This three-volume set of Pharmaceutical Dosage Forms: Parenteral Medications is an authoritative, comprehensive reference work on the formulation and manufacture of parenteral dosage forms, effectively balancing theoretical considerations with the practical aspects of their development. Pharmaceutical active compounds and the excipients are in contact with each other a period of time before the pharmaceutical formulation is used by a patient; hence, the storage conditions are very important—humidity and temperature can trigger interactions between a drug and an excipient and these interactions may affect drug bioavailability and even drug safety. In view of the importance of simplifying antibiotic treatment of critically ill newborns before they reach health facilities, this article focuses on CTX preformulation studies of solid and liquid non-parenteral drug dosage forms for further pharmaceutical development. Parenteral-applied through the skin ... 1.5 General Considerations in Dosage Form Design Preformulation studies Drug and Drug Product Stability For rational design of the dosage forms, preformulation is an important development step used to characterize the properties of drug substance and also to understand the challenges that a particular compound may possess during the formulation. Most synthetic drugs are either weak bases (~75%) or weak acids (~20%), and will generally need to be formulated as salts. Preformulation studies. We present the thermal and spectroscopic study of drug/polymer physical mixtures containing ibuprofen (IB), clindamycin hydrochloride (CD), metronidazole (MZ), as the active pharmaceutical ingredient (API) and hydroxypropyl methylcellulose (HPMC K100M), Poloxamer 407, polyethylene oxide (PEO 1105) and polycarbophil (Noveon AA1) as excipients, defined as prototype formula.
