Co-crystals consists of API and a stoichiometric amount of a pharmaceutically acceptable co-crystal former. Pharmaceutical Co-crystals are nonionic supramolecular complexes and can be used to address physical property issues such as solubility, stability, and bioavailability in pharmaceutical development without changing the chemical composition of the API. Cocrystal is a crystalline entity formed by two different or more molecular entities where the intermolecular interactions are weak forces like hydrogen bonding and π- π stacking. Super porous systems, biodegradable hydrogel systems. Co-crystallization alters the molecular interactions and composition of pharmaceutical materials and is considered a better alternative to optimize drug properties. Co-crystals offer a different pathway, where any API, regardless of acidic, basic, or ionizable groups, could potentially be co-crystallized. This aspect also helps complement existing methods by reintroducing molecules that had limited pharmaceutical profiles based on their nonionizable functional groups. The article gives a brief review of the co-crystallization, its difference from other states and its importance as an alternative over slat formation. The review also highlights the current FDA...

Spirulina platensis, planktonic blue-green algae, has been used as a source of protein (60-70%) and vitamin supplement for more than 15 years without any unknown adverse events. Traditionally, Spirulina platensis has been used as an antioxidant agent. However, no pharmacological work has been done to evaluate the anti-anxiety activity. The present study was premeditated for the evaluation of the anti-anxiety activity of Spirulina platensis. Elevated plus maze (EPM) and light-dark models were used to evaluate the anti-anxiety potential of Spirulina platensis in Swiss albino mice. Albino mice were treated orally with diverse doses of the Spirulina platensis (i.e., 300 and 400 mg/kg). Diazepam (2 mg/kg, IP) was used as a standard drug. In conclusion, 400 mg/kg dose of Spirulina platensis showed significant anti-anxiety activity (P<0.05) while the control group was near to standard group. It concludes that Spirulina platensis could be useful as an anti-anxiety agent for...

Objective: To investigate the patient’s knowledge of hypertension fact with validated Morisky questionnaires and management of drug adherence. Materials and Methods: The aim of one present study was undertaken 100 patients attending the cardiology, outpatient department in various private sector hospitals in southern Tamilnadu and to assess the patient’s medication knowledge and drug adherence on hypertension with validated questionnaires method. Results: Out of 100 hypertensive patients (17%) of the subjects had adequate, (21%) of the patients had moderate medication knowledge about hypertension or maximum while (62%) were categorized as poor medication and adherence 35% of the people are in medium adherence only 3% are in high adherence. Conclusion: The disease knowledge of subjects’ rate was low, and patients were unsure of the benefits of continuous medication use and resulted in non-adherence. Educating hypertensive patients clarifying doubt regarding the benefits of adherence, medication uses, and control...

The present study was carried out to investigate the protective effect of ethanolic extract of Madhuca latifolia (Roxb.) bark (MLE) and aqueous extract of Madhuca latifolia (Roxb.) bark (MLA) in aspirin-induced gastric ulcer. In both extract, acute toxicity performed according to guidelines for the selection of doses. The oral administration (400 mg/kg) of MLE & MLA extract reduced the ulcer index and prevents the development of gastric lesions by 76.57% and 81.14% (% of protection), respectively. The present studies provide preliminary data on the antiulcer potential of bark and support the traditional uses of the plant for the treatment of gastric...

Aripiprazole is an anti-psychotic drug used in the treatment of psychosis, including schizophrenia, and during process development for Aripiprazole, we observed two related substances. This paper describes the preparation, identification and proposed structures of the impurities 7-(4-(4-(2-chlorophenyl) piperazine-1-yl) butoxy) – 3, 4 – dihydroquinoline – 2(1H) – one and 7- (4-(4-(3-chlorophenyl)piperazin-1-yl) butoxy)-3,4-dihydroquinoline-2(1H)-one formed during reaction of 7-(4-bromobutoxy)-3, 4-dihydroquinoline-2(1H)-one with 1-(2, 3-dichloro phenyl) Piperazine Hydrochloride to form...
