In vivo anticonvulsant activity of 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine in pilocarpine and strychnine induced-seizure models

An imbalance between inhibitory (GABA) and excitatory (Glutamate) neurotransmission contribute to the development of epilepsy. Earlier studies reported that dysregulation of GABA and glutamatergic activities resulted in status epilepticus (SE) and ultimately support the development of temporal lobe epilepsy (TLE), a type of resistant epilepsy. In the earlier work, 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine demonstrated anticonvulsant activity against pentylenetetrazole (PTZ)-induced seizures. Apart from the PTZ-induced TLE, the dysregulation muscaranic receptors and glycine receptors are also widely reported phenomena in the development of temporal lobe epilepsy. Keeping the role of these two receptors in epilepsy, the present work investigated the effect of 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine in pilocarpine-induced and strychnine-induced seizure models. Our results demonstrated that 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine significantly delayed the onset of seizure with maximum protection from SE in pilocarpine-induced seizure model. However, the test compound did not revealed any effect on strychnine-induced seizures in mice. Based on these observations, we suggest that 2-propanone-1,3,5,5-trimethyl-2-cyclohexen-1-ylidine could be a potential candidate in reduction of SE and treatment of temporal lobe epilepsy (TLE) in future.

Adverse drug reactions (ADRS) reporting: awareness and reasons of under-reporting among health care professionals, a challenge for pharmacists

OBJECTIVES

To measure awareness about adverse drug reaction (ADRs) reporting among doctors, pharmacists and nurses and to determine reasons of ADRs under-reporting in Pakistan.

METHODS

In present study, a self-administered questionnaire was used to measure the awareness level about ADRs reporting among health care professionals (HCPs) of Pakistan. This was a cross sectional study.

RESULTS

Out of the respondents 51 % were physicians, 29.7 % pharmacists and 19.3 % were nurses. 65.5 % of HCP population observed ADRs, out of which only 57.4 % reported these in their respective hospitals. About 77.3 % of population understood the importance of reporting ADRs while 67.3 % of population agrees that pharmacists are chief personnel for the development of system. 71.8 % of HCPs agrees that ADRs are not reported because Community pharmacy lacks legally qualified pharmacists. Only 14.3 % of HCPs population knows that there is any ADR reporting organization in Pakistan.

CONCLUSION

The study recommends the need of such reporting system and more than half of the studied population agreed that pharmacists are required in developing such system.
