Aspirin is a nonsteroidal anti-inflammatory drug. Aspirin is unique in this class of drugs because it irreversibly inhibits both COX-1 and COX-2 activity by acetylating a serine residue (Ser529 and Ser516, respectively) positioned in the arachidonic acid-binding channel, thus inhibiting the synthesis of prostaglandins and reducing the inflammatory response. The drug is used either alone or in combination with other compounds for the treatment of pain, headache, as well as for reducing the risk of stroke and heart attacks in patients with brain ischemia and cardiovascular diseases.

Methyl salicylate (or methyl 2-hydroxybenzoate), also known as wintergreen oil, is a natural product and is present in white wine, tea, porcini mushroom Boletus edulis, Bourbon vanilla, clary sage, red sage and fruits including cherry, apple, raspberry, papaya and plum. Methyl salicylate is topically used in combination with methanol and under brand name SALONPAS to temporarily relieves mild to moderate aches and pains of muscles and joints associated with: strains, sprains, simple backache, arthritis, bruises. The precise mechanism of action of methyl salicylate is not known, but there is suggested, that it cause dilation of the capillaries thereby increasing blood flow to the area.

Nomifensine was developed by Hoechst AG as a potent inhibitor of noradrenaline, dopamine, and 5-HT uptake displayed antidepressant activity. It was first marketed in the UK in 1977 for the treatment of depression. Between 1977 and 1982 there were reports of hemolytic anemia in association with the drug, and this suspected adverse reaction was included in the 1981 edition of the data Sheet Compendium. FDA published a notice of its determination that Merital capsules were removed from the market for safety reasons.

Methaqualone is a depressant that modulates the activity of the GABA receptors in the brain and nervous system. It promotes relaxation, sleepiness and sometimes a feeling of euphoria. It causes a drop in blood pressure and slows the pulse rate. These properties are the reason why it was initially thought to be a useful sedative and anxiolytic. Common side effects of Methaqualone include dizziness, nausea, vomiting, diarrhea, abdominal cramps, fatigue, itching, rashes, sweating, dry mouth, tingling sensation in arms and legs, seizures and its depressant effects include reduced heart rate and respiration. The drug became banned in many countries and was withdrawn from many markets in the early 1980s.

Propoxyphene is a centrally acting opiate analgesic. Propoxyphene is an odorless, freely soluble in water, white crystalline powder with a bitter taste. In vitro studies demonstrated propoxyphene and the metabolite norpropoxyphene inhibit sodium channels (local anesthetic effect) with norpropoxyphene being approximately 2 fold more potent than propoxyphene and propoxyphene approximately 10 fold more potent than lidocaine. Propoxyphene and norpropoxyphene inhibit the voltage-gated potassium current carried by cardiac rapidly activating delayed rectifier (hERG) channels with approximately equal potency. It is unclear if the effects on ion channels occur within therapeutic dose range. Propoxyphene is indicated for the relief of mild to moderate pain.

Pipradrol (Meratran) is a psychoactive agent and a central nervous system stimulant useful in the field of psychiatry. In vitro study has shown that pipradrol inhibits the reuptake of and stimulates the release of dopamine and norepinephrine. In these pharmacodynamic actions it is less potent than d-amphetamine. It was shown that pipradrol conditioned place preference (CPP) was blocked by selective D1 dopamine antagonist SCH23390 suggesting that a rewarding effect of pipradrol establishment of a CPP may involve activation of D1 dopamine receptors. Pipradrol was initially used as an adjunct in the dietary management of obesity as well as for the treatment of dementia. There have been a number of reports on the properties of pipradrol showing its favorable effects in the treatment of depression and fatigue status as well as a variety of other conditions including narcolepsy, spasmodic torticollis, schizophrenia and in geriatric practice. Pipradrol has a definite cerebral stimulating effect without affecting the blood pressure or respiration and has been used to counteract post-anasthetic and chlorpromazine depression in man. Structurally related to -phenylmethylamphetamine, a potent stimulant with a long half-life, pipradrol differs from amphetamine in that its action is more intense at higher centres, it lacks pressor activity, there is no post-excitement depression, and it does not depress the desire for food as occurs with amphetamine. The drug however is enhancing the existing pathologic behavior such as exacerbating pre-existing anxiety and is considered the drug of abuse. Meratran has certain indications and contraindications. Indications are schizophrenics without delusions having restriction of interest and activity and with depressant features, psycho-motor retardation and/or blocking of communication, long-term hospitalized schizophrenics with severe deterioration while contraindications are patients with delusions, anxiety, disturbed patients with cerebral arteriosclerosis. Pipradrol was made illegal in many countries in 1970s due to its abuse potential. It is classified under the Misuse of Drugs Act as a Class C substance. The combination of pipradrol with multivitamins and minerals marketed as Alertonic Elixir is used as adjunctive therapy in combating fatigue resulting from emotional or nutritional causes.

VINBARBITAL, a barbiturate derivative, is a hypnotic drug. Also, it was used for analgesia and anesthesia in obstetrics.
