Moricizine Action Pathway

Homo sapiens
Moricizine is an antiarrhythmic used to treat arrhythmias (irregular heartbeats) and to maintain normal heart rate. it acts on heart muscles by inhibiting inward sodium channels. This results in a slowed atrioventricular nodal and His-Purkinje conduction, which decreases excitability conduction velocity, and automaticity. It decreases the maximum rate of phase 0 depolarization, but it does not affect action potential amplitude, sinoatrial (SA) nodal or intra-atrial conduction, or maximum diastolic potential. It minimally effects sinus cycle length and sinus node recovery time.

Moricizine Drug Metabolism

Homo sapiens
Moricizine is a drug that is not metabolized by the human body as determined by current research and biotransformer analysis. Moricizine passes through the liver and is then excreted from the body mainly through the kidney.

Moroctocog Alfa Action Pathway

Homo sapiens
Moroctocog alfa also known as Refacto AF and Xyntha, is a B-domain deleted recombinant factor VIII similar to the endogenous coagulation factor VIII. Moroctocog alfa is administered intravenously used to treat hemophilia A to control bleeding. It acts by replacing coagulation factor VIII which is deficient in those with hemophilia, this allows coagulation factor IX and X to be activated and facilitate the clotting cascade.

Morphine Action Pathway

Homo sapiens
Morphine exerts its analgesic by acting on the mu-opioid receptor of sensory neurons. Binding to the mu-opioid receptor activates associated G(i) proteins. These subsequently act to inhibit adenylate cyclase, reducing the level of intracellular cAMP. G(i) also activates potassium channels and inactivates calcium channels causing the neuron to hyperpolarize. The end result is decreased nerve conduction and reduced neurotransmitter release, which blocks the perception of pain signals.

Morphine Action Pathway Xuan Demo

Homo sapiens
Morphine is a class of drugs known as opioid (narcotic) analgesics. It can help to relieve moderate to severe pain, which by changing how your body feels and responds to pain. Morphine will activate mu-type opioid receptor, which the later will activate the G-proteins (guanine nucleotide-binding proteins). G proteins regulate metabolic enzymes, ion channels, transporter proteins. In this pathway, G proteins activate potassium voltage-gated channel (GIRK) as well as inhibit calcium voltage-gated channel and SNARE proteins. SNARE proteins mainly mediate the vesicle fusion. In this pathway, the synapse vesicles are required to be fused into cell membrane in order to release the neurotransmitter from brain cell. Inhibition of SNARE proteins deregulates the fusion of synapse vesicles which make neurotransmitter unable to be released as result. In order words, the pain signal (as in the neurotransmitters) won't be able to pass across the brain. Therefore, the pain is relieved in some extent.

Morphine Opioid Agonist Action Pathway

Homo sapiens
Morphine is an opioid agonist used for the relief of moderate to severe acute and chronic pain. Morphine can be administered orally as a capsule or tablet, intravenously, intrathecally, or as an epidural. Morphine-6-glucuronide, a metabolite of morphine, is responsible for approximately 85% of the response observed by morphine administration, however morphine may have greater analgesic efficacy. Morphine binds to mu opioid receptors, stimulating the exchange of GTP for GDP on the G-protein complex. As the effector system is adenylate cyclase and cAMP located at the inner surface of the plasma membrane, opioids decrease intracellular cAMP by inhibiting adenylate cyclase. Subsequently, the release of nociceptive neurotransmitters such as GABA is inhibited. Opioids close N-type voltage-operated calcium channels and open calcium-dependent inwardly rectifying potassium channels. This results in hyperpolarization and reduced neuronal excitability. Morphine acts at A delta and C pain fibres in the dorsal horn of the spinal cord. By decreasing neurotransmitter action there is less pain transmittance into the spinal cord. This leads to less pain perception. Morphine also binds to delta and kappa opioid receptors in the nucleus accumbens where the reward pathway is activated.
