Nytol is a brand of sleeping pill produced by Prestige Brands. The active ingredient is diphenhydramine hydrochloride, a sedative antihistamine. GlaxoSmithKline acquired the product in 2001 with the purchase of Block Drug. GSK sold a number of OTC brands in 2011 to Prestige Brands. Iphenhydramine enters the brain in significant quantities and causes drowsiness. It decreases the time taken to fall asleep and increases the depth and quality of sleep. This makes it helpful for the temporary relief of sleeping difficulties. In the United Kingdom and Canada it is available over the counter.

Wellbutrin , Bupropion , Anfebutamona, Aplezin, Zyban, is a drug primarily used as an antidepressant and smoking cessation aid. Marketed as Aplenzin, Budeprion, Elontril, Wellbutrin or other trade names, it is one of the most frequently prescribed antidepressants in the United States. Although in many English-speaking countries, including the United Kingdom, Australia and New Zealand, this is an off-label use. Marketed in lower-dose formulations as Prexaton, Voxra, Zyban, or other names, it is also widely used to aid people who are trying to quit smoking. It is taken in the form of tablets, and in the United States and most other countries it is available only with a prescription. Clinically, bupropion serves as an atypical antidepressant fundamentally different from most commonly prescribed antidepressants such as selective serotonin reuptake inhibitors (SSRIs). It is an effective antidepressant on its own, but is also popular as an add-on medication in cases of incomplete response to first-line SSRI antidepressants. In contrast to many other antidepressants, it does not cause weight gain or sexual dysfunction. The most important side effect is an increase in risk for epileptic seizures, which caused the drug to be withdrawn from the market for some time and then caused the recommended dosage to be reduced.
