Mechanism of Action

How Реметан Works: Mechanism of Action

The compound Реметан (Mirtazapine) acts by directly engaging and modifying key neurotransmitter systems in the brain. Its action involves two primary, interconnected mechanistic domains, characterized by a dual action on chemical signaling and central arousal.

️ Disinhibition of Norepinephrine and Serotonin Signaling

This domain describes the compound's action as an antagonist on presynaptic alpha2-adrenergic autoreceptors . By blocking these feedback mechanisms, Реметан triggers an enhanced release of both Norepinephrine and Serotonin into the synaptic gap. This mechanism contributes to increased signaling activity within circuits that process physiological responses.

Selective Receptor Modulation and Central Histamine Blockade

Реметан modulates its action by also acting as an antagonist on specific postsynaptic Serotonin receptors (5-HT2 and 5-HT3). This action functionally redirects the increased Serotonin to the 5-HT1 receptors. Simultaneously, the compound blocks the central Histamine H1 receptor, a mechanism that results in decreased signaling through the central arousal pathway, which constitutes a component of the compound's overall physiological action.

Dosage and Administration Information

How Реметан is used: Official Administration Guidelines

Реметан (Diclofenac) is administered through several officially approved routes, including oral (tablets, capsules, solutions), topical (gels or solutions), and parenteral (intravenous or intramuscular injection). The core principle governing all use is to apply the lowest effective dose for the shortest duration necessary.

For oral administration in chronic conditions such as Osteoarthritis, the typical daily dose may range from 100 mg to 150 mg, administered in two or three divided doses. Certain extended-release formulations are dosed as 100 mg once daily. The specific dosage form dictates the frequency of intake, with immediate-release forms requiring multiple daily doses.

Specific instructions define how formulations must be handled. For instance, delayed-release tablets must be swallowed whole and must not be crushed, chewed, or divided to maintain their release properties. The powder for oral solution must be mixed only with water and ingested immediately on an empty stomach for acute pain.

The parenteral (IV) route is restricted to short-term, acute pain management, generally involving doses of 37.5 mg every six hours, not to exceed 150 mg per day. Furthermore, treatment for older adults is typically initiated using the lowest effective dosage available to align with population-specific considerations.
