Drug Name Anafranil

The site and mechanism of action of barbiturates, antihistamines, and chloral hydrate are incompletely understood. All hypnotics shorten the time spent in the REM stages (B). With repeated ingestion of a hypnotic on several successive days, the proportion of time spent in REM vs. non-REM sleep returns to normal despite continued drug intake.
To ensure a reasonably long-lasting local effect with minimal systemic action, a vasoconstrictor (epinephrine, less frequently norepinephrine or a vasopressin derivative;) is often co-administered in an attempt to confine the drug to its site of action.

 

Effexor XR (Venlafaxine HCl) Extended-Release Capsules are indicated for the treatment, in adults, of Depression, Generalized Anxiety Disorder (GAD), Social Anxiety Disorder (SAD), and Panic Disorder (PD) with or without agoraphobia.
Only when monotherapy with different agents proves inadequate can changeover to a second-line drug or combined use (“add on”) be recommended (B), provided that the possible risk of pharmacokinetic interactions is taken into account (see below). The precise mode of action of antiepileptic drugs remains unknown. Some agents appear to lower neuronal excitability by several mechanisms of action.
