In the pharmaceutical industry, Pyridoxine Hydrochloride 25 mg is the therapeutic form of Vitamin $B_6$. As a pharmacist and manufacturer, I view this 25 mg strength as a high-precision dose used both for correcting nutritional deficiencies and as a critical adjunct in managing the side effects of other potent drugs.

At your WHO-GMP facility in Mumbai, Pyridoxine 25 mg is a vital SKU, particularly for export to regions where it is co-prescribed with anti-tuberculosis medications.

Primary Clinical Indications

• Prevention of Peripheral Neuropathy: Specifically used in patients taking Isoniazid (INH) for Tuberculosis. Isoniazid depletes $B_6$ levels, and 25 mg is the standard protective dose to prevent nerve damage (numbness and tingling).

• Pregnancy-Induced Nausea: Often used as a first-line, non-pharmacological approach for “morning sickness,” frequently combined with Doxylamine.

• Sideroblastic Anemia: Used to treat certain types of anemia where the body cannot properly incorporate iron into hemoglobin.

• Premenstrual Syndrome (PMS): Sometimes utilized to alleviate mood-related symptoms and bloating.

• Metabolic Disorders: Management of $B_6$-dependency syndromes like homocystinuria or primary hyperoxaluria.

Mechanism: The Co-Enzyme Catalyst

Pyridoxine is not just a vitamin; it is a catalyst for over 100 enzymatic reactions in the body.

Neurotransmitter Synthesis: It is essential for the production of Serotonin, Dopamine, and GABA, which regulate mood and neurological stability.

Heme Production: It acts as a co-factor in the synthesis of heme, the oxygen-carrying component of red blood cells.

Isoniazid Interaction: Isoniazid binds to Pyridoxine, creating a complex that the body excretes. Taking 25 mg “replaces” this loss, ensuring the nervous system remains protected.

The Pharmacist’s “Technical Warning”

As you promote your firm on digital platforms, providing these technical nuances is essential for clinical authority:

• The Paradoxical Neuropathy: While used to treat nerve pain, chronic overdose (typically >200 mg daily) can actually cause sensory neuropathy. At 25 mg, this risk is virtually non-existent, but it is a vital “Pharmacist’s Note”.

• Levodopa Interaction: Pyridoxine can reduce the effectiveness of Levodopa (used for Parkinson’s) by speeding up its breakdown before it reaches the brain. It is usually avoided in these patients unless they are also taking Carbidopa.

The Manufacturer’s Perspective: Technical & Export

From a production and B2B standpoint at your facility in Mumbai:

• The “TB-Kit” USP: On your marketplace, market the 25 mg tablet as the “Essential TB Companion.” In international health tenders for Africa and SE Asia, Pyridoxine is almost always requested alongside anti-TB drugs.

• Stability for Export: Pyridoxine is stable but highly light-sensitive. Utilizing Alu-Alu blister packaging or Amber-colored PVDC is critical to ensure a 36-month shelf life in Zone IVb tropical regions.

• Dossier Support: We provide full CTD/eCTD Dossiers to support your firm’s registration in international health tenders and global aid organization bidding.
