Nonsteroidal anti-inflammatory hydrophobic drugs (NSAIDs) are amongst the most commonly given categories of drugs worldwide in the treatment of pain, irritation and some of them even fever in many conditions. Critical micelle concentration of NSAIDs with Naproxen sodium (NS) and its mixture with non-ionic surfactants i.e. Tween 20, Tween 40 and Tween 60 was investigated at 293 K, 303 K, 313 K and 323 K at different concentrations using surface tension and dynamic laser light scattering (DLS) techniques. Due to amphiphilic behaviour in aqueous solution NS form aggregates at sufficiently high concentration. Thermodynamic/adsorption properties like free energy of micellization (ΔGmic), enthalpy of micellization (ΔHmic), entropy of micellization (ΔSmic), Γmic and area per molecule (A2) of NS in the presence of surfactants were also measured at different temperatures. The results showed that the presence of surfactants favoured the ΔGmic and become more enhanced with increase in temperature. Further the solubility of drug is more favourable with increase in polyethylene chain in basic surfactant molecules i.e. 20–60, which indicates that Tween-60 enhanced the solubility of NS more comparatively to Tween-40 and Tween-20 and may be applied as best additive for solubilisation of NS.

Hepatitis C virus (HCV) leads to liver cirrhosis and carcinoma worldwide. The data of HCV cirrhotic patients were collected from hospitals of Peshawar in the period from 2015 to 2018. A total sample of 267 patients, in the age limit (>19 and <87 years) were found to be cirrhotic and HCV positive. The samples were analyzed through different tests, that is, raised alkaline phosphatase (410 IU/L), aspartate aminotransferase (209 U/L), and reverse transcription-polymerase chain reaction (PCR) viral load (>5,000,000 IU/mL). The mean and standard deviation (SD) of alanine transaminase and alpha fetoprotein were noted, (121.46 -29.23) and (43.09 -28.08), respectively. Samples of HCV cirrhotic patients (59.6% males and 40.4% females) were included and their mean age and SD of the patients was 49.62 -12.65 years. The Child-Turcotte-Pugh Score system was assessed on the base of liver disease. High blood pressure was observed in 26.2%, low in 40.8%, and normal in 33% of patients. The ascites was recorded high in 59% patients (male 38.6%, female 20.6%) and the level of albumin was abnormal in 64.5% patients. Furthermore, multiplex PCR was run to determine HCV genotypes. The frequency of HCV genotype 3a was 47.9%, 2a and 3b was 11%, 1a was 6%, and 1b was 1%; 4.1% were mixed genotypes and 18.7% were untypable genotypes in these patients. The HCV genotype 3a was found a major prevalent genotype in Khyber Pakhtunkhwa patients and it was observed that the HCV cirrhosis issue was significantly increased in the province.
