Nitroglycerin is used in the treatement of angina pectoris and perioperative hypertension.

Nitrous Oxide

Nitrous oxide is an oxide of nitrogen. It is used in surgery and dentistry for its anesthetic and analgesic effects. It is known as "laughing gas" due to the euphoric effects of inhaling it, a property that has led to its recreational use as a dissociative anesthetic. It is also used as an hybrid oxidizer in rocketry and in motor racing to increase the power output of engines. At elevated temperatures, nitrous oxide is a powerful oxidizer similar to molecular oxygen.

Novata 299 PH

Novata 299 PH are white to slightly yellowish, brittle pellets which are used for the production of suppositories. On account of the higher hydroxyl value range, active agents can be integrated which react with hydroxyl groups.


Oxymetazoline was developed from xylometazoline at E.Merck Darmstadt by Fruhstorfer in 1961. It is used to treat epistaxis and eye redness due to minor irritation.

Oxymorphazone is an opioid analgesic drug related to oxymorphone. It is a potent and long acting μ-opioid agonist which binds irreversibly to the receptor, forming a covalent bond which prevents it from detaching once bound. This gives it an unusual pharmacological profile, and while oxymorphazone is only around half the potency of oxymorphone, with higher doses the analgesic effect becomes extremely long lasting, with a duration of up to 48 hours. However with repeated doses, tolerance to the effects develops rapidly, as chronically activated opioid receptors are rapidly internalised by β-arrestins, in a similar manner as occurs with non-covalent binding by agonists with extremely high binding affinity such as lofentanil.


Pentamorphone is a semi-synthetic opiate derivative related to compounds such as morphine, hydromorphone and oxymorphone. Developed in 1984, it is a potent opioid analgesic several times stronger than fentanyl, and with a similarly fast onset of effects and short duration of action. It was found to produce relatively little respiratory depression compared to other potent opioid agonists, but its analgesic effects were somewhat disappointing in human trials, and while pentamorphone had some slight advantages over fentanyl these were not sufficient to warrant its introduction into clinical use.


Pentobarbital is a short-acting barbiturate that was first synthesized in 1928. Pentobarbital's FDA-approved human uses include treatment of seizures and preoperative (and other) sedation; it is also approved as a short-term hypnotic.
