Diphenhydramine is an antihistamine and works as a topical anti-allergic and analgesic by blocking the releases of histamine at its sources. Zinc is used as a skin protectant.

Donepezil Hydrochloride is a centrally acting anticholinesterase agent. It binds reversibly with acetylcholinesterase and inactivates it, thus inhibiting hydrolysis of acetylcholine. As a result the concentration of acetylcholine increases at choline...

Dopamine is a preparation of Dopamine hydrochloride which can stimulate α, β and dopamine receptors. It is a natural catecholamine formed by the decarboxylation of 3,4-dihydroxyphenylalanine (DOPA). Dopamine is a precursor to norepinephrin...

Doxorubicin hydrochloride is a cytotoxic, anthracycline topoisomerase IIinhibitor. The cytotoxic effect of Doxorubicin HCl on malignant cells and its toxic effects on various organs are thought to be related to nucleotide base intercalation and cell...

Doxycycline Hydrochloride is a semisynthetic tetracycline antibiotic with broad spectrum activity. It is primarily a bacteriostatic antibiotic. It has a similar spectrum of activity to other tetracyclines but in particular is more active against Stap...

Drotaverine HCl is a new potent synthetic antispasmodic drug which is readily absorbed from the intestine. Like papaverine, it acts directly on the smooth muscle fibers exceeding however, the antispasmodic effect of the standard preparations. Drotave...

Duloxetine Hydrochloride is a selective serotonin and norepinephrine reuptake inhibitor (SSNRI) for oral administration. Duloxetine is a less potent inhibitor of dopamine reuptake. Duloxetine has no significant affinity for dopaminergic, adrenergic,...

Eperisone is centrally-acting skeletal muscle relaxant used to improve myotonic symptoms.

Nandrolone Decanoate is an injectable anabolic preparation. The pharmacologically active substance is nandrolone. The decanoate ester gives the preparation duration of action of about three weeks after injection. Nandrolone Decanoate is chemically re...

Pazopanib is a multi-tyrosine kinase inhibitor of vascular endothelial growth factor receptor (VEGFR)-1, VEGFR 2, VEGFR-3, platelet-derived growth factor receptor (PDGFR)-α and -β, fibroblast growth factor receptor (FGFR)-1 and -3, cytokin...

The efficacy of Paroxetine is presumed to be linked to potentiation of serotonergic activity in the central nervous system resulting from inhibition of neuronal reuptake of serotonin (5-hydroxy-tryptamine, 5 HT). Studies at clinically relevant doses...

Paracetamol has analgesic and antipyretic properties with weak anti-inflammatory activity. Paracetamol (Acetaminophen) is thought to act primarily in the CNS, increasing the pain threshold by inhibiting both isoforms of cyclooxygenase, COX-1, COX-2,...

Oxymorphone is an opioid agonist whose principal therapeutic action is analgesia. Like all pure opioid agonist
analgesics, with increasing doses there is increasing analgesia, unlike with mixed agonist/antagonists or non opioid analgesics, where...

Oxymetazoline Hydrochloride is an imidazoline derivative sympathomimetic amine. It is a direct agonist at α-adrenoceptors but has no action on β- adrenoceptors. It is used as a topical agent on the nasal mucosa, produces a rapid and long a...

Oxybuprocaine is a local anaesthetic. It may be less irritating than tetracaine, and the onset and duration of action are similar to tetracaine. Oxybuprocaine binds to sodium channel and reversibly stabilizes the neuronal membrane which decreases its...

Olopatadine, an antihistamine, works by blocking the action of histamine in the body, which reduces allergy symptoms. Olopatadine hydrochloride treats sneezing, itching, runny nose, and other nasal symptoms of allergies.
