Ranitidine Hydrochloride: Classification and Identity

Ранитидин Софарма is an antisecretory medicine whose active substance is Ranitidine Hydrochloride (INN: Ranitidine), a compound clinically recognized for its role in managing conditions associated with excess stomach acid. The drug is definitively classified as a Histamine H2-receptor antagonist (or H2-blocker), due to its specific method of pharmacological action on parietal cells in the stomach. This classification indicates that the medicine functions by blocking the action of histamine at specific receptors, which in turn leads to the inhibition of acid secretion. This substance is a synthetic small molecule drug, manufactured chemically, and is structured as a single active ingredient product (Monopreparation). The manufacturing entity, Софарма AD, is based in Bulgaria.

Pharmaceutical Forms and General Therapeutic Purpose

The medicine is supplied in various pharmaceutical forms for patient administration, including film-coated tablets for oral ingestion and a sterile solution for injection for parenteral (intravenous or intramuscular) use. These forms contain the active Ranitidine Hydrochloride alongside necessary pharmaceutical vehicles, such as water for injection for the liquid form, ensuring stable delivery. Ranitidine's pharmacological class is widely recognized for its general ability to manage symptoms associated with hyperacidity, confirmed through decades of clinical practice. The core purpose of the drug is to achieve a significant reduction in the secretion of hydrochloric acid within the stomach. By performing this function, the medicine generally helps to relieve discomfort and pain associated with hyperacidity and creates a reduced-acid environment that supports the natural healing and integrity of the digestive tract lining.

What side effects are possible with Ранитидин Софарма?

The safety profile of Ranitidine Hydrochloride is defined by official regulatory documentation, classifying possible adverse reactions by frequency and the body system affected. This section adheres strictly to the findings published by governmental health authorities.

Frequency and System-Organ Classifications

Adverse reactions are classified based on the estimated frequency observed in clinical use. Common reactions (affecting up to 1 in 10 patients) primarily affect the Nervous System and the Gastrointestinal System, typically including headache, diarrhoea, or constipation. Uncommon reactions include transient, reversible alterations in liver function tests, indicative of effects on the Hepatobiliary System.

Rare adverse reactions include acute pancreatitis, acute interstitial nephritis, and serious Hypersensitivity Reactions such as urticaria and fever. Liver inflammation (hepatitis), which may present with or without jaundice, is also documented as a rare event.

Serious Adverse Reactions and Population Notes

Events classified as Very Rare (affecting up to 1 in 10,000 patients) include severe, acute hypersensitivity (anaphylactic shock) and severe disorders of the Blood and Lymphatic System, such as agranulocytosis and pancytopenia. These serious haematological and hepatic effects are generally considered reversible upon cessation of exposure.

Population-Specific Considerations are noted in official labeling. Mental confusion and hallucinations are reported to occur more frequently in older adults and severely ill patients. The long-term use of the medicine has also been associated with the very rare development of gynecomastia (enlargement of breast tissue in males).

Overdose and Emergency Response

Overdose and When to Seek Help — Official Regulatory Information

The official overdose information for Ranitidine Hydrochloride emphasizes that while specific problems are generally not expected following overdosage with oral formulations, certain severe manifestations have been documented, and immediate medical action is required.

This profile dictates that immediate professional medical help must be sought in all cases of suspected overdose to allow for necessary cardiac monitoring and symptomatic supportive care.

Therapeutic Uses of Ранитидин Софарма

What Ранитидин Софарма Treats: Main Uses and Benefits

Ранитидин Софарма is a pharmaceutical product used in managing conditions related to excess stomach acid. The therapeutic applications are focused on addressing and relieving the associated discomfort.

The primary uses include the treatment and prevention of ulcers in the gastrointestinal tract, such as duodenal and gastric ulcers. It is also used in the management of gastroesophageal reflux disease (GERD), which involves the backward flow of stomach acid into the esophagus, commonly causing heartburn. Furthermore, this medication is indicated for treating conditions that cause the stomach to secrete an excessive amount of acid, such as Zollinger-Ellison syndrome.

The benefit of using this product is the reduction of gastric acid secretion, which helps in the healing process of ulcers and provides reliable relief from symptoms like persistent heartburn, stomach pain, and related discomfort. The treatment helps to alleviate symptoms and reduce the frequency of relapse for these acid-related issues.

Eligibility and Restrictions for Use

Who Can and Cannot Use Ranitidine Sopharma

Eligibility for using Ranitidine Sopharma (Ranitidine Hydrochloride) is strictly defined by regulatory guidelines concerning patient demographics and pre-existing conditions.

Contraindications and Prohibited Use

Category Population / Condition
Absolute Contraindication Patients with a known hypersensitivity to ranitidine or any component of the formulation.
Absolute Contraindication Patients with a history of acute porphyria, as use is avoided in this population.

Restricted and Conditional Use

Category Restriction
Renal Function Use in patients with severe renal impairment (creatinine clearance < 50 mL/min) is restricted and requires a mandatory dosage adjustment.
Hepatic Function Caution should be observed in patients with hepatic dysfunction.
Comorbidity The possibility of gastric malignancy must be excluded before initiating therapy, especially in middle-aged or older patients with new dyspeptic symptoms.
Age Threshold Safety and efficacy in new-born patients (under 1 month) have not been established.
Reproductive Status Use during pregnancy and lactation is only recommended where it is considered essential.

Approved Age Groups

Ranitidine is generally approved for use in adults and adolescents (12 years and over). Use is also established in children aged 3 to 11 years and infants aged 1 month to less than 3 years for approved indications under medical guidance.

What should I know about interactions with other medicines?

The official interaction profile for Ranitidine Hydrochloride is defined by its pharmacokinetic effects on co-administered medicines and formal restrictions on combination therapy.

Interactions Altering Drug Exposure

The reduction of gastric acid secretion by Ranitidine may alter the systemic absorption and consequently reduce the exposure and effectiveness of products that require a low gastric pH for proper uptake. This interaction is formally documented for pH-dependent medicines, including specific antifungals, antivirals, and kinase inhibitors such as Atazanavir, Dasatinib, and Ketoconazole.

Conversely, some substances may increase exposure: Propantheline slightly delays and increases Ranitidine's peak plasma levels. Official data shows that co-administration with Triazolam results in increased Triazolam exposure, with mean Area Under the Curve ( AUC) values rising by up to 28%.

Restrictions and Timing Rules

Interaction restrictions include a prohibition on combining Ranitidine with other H2-receptor antagonists to avoid therapeutic duplication. Simultaneous administration of high-potency antacids is officially documented to decrease Ranitidine's absorption, requiring administration separation.

Coagulation and Food

While formal pharmacokinetic studies showed no interaction with Warfarin, reports exist of altered prothrombin times (increased or decreased) during concurrent use. The product's absorption is not significantly impaired by food.

Mechanism of Action

How Ранитидин Софарма Works

The action of Ranitidine is a process of targeted receptor blockade that acts directly on the signaling pathways regulating gastric acid secretion.

Selective Blockade of the Histamine H2 Receptor

Ranitidine acts as a competitive antagonist at the Histamine H2 receptor located on the gastric parietal cell membrane. By occupying this receptor, the drug prevents the natural chemical messenger, histamine, from initiating the molecular cascade that stimulates acid secretion.

Modulating the Basal Acid Secretion Pathway

The drug's antagonism suppresses the intracellular signaling cascade (involving cAMP) that normally activates the final Proton Pump ( H^+/ K^+-ATPase). The mechanism demonstrates greater influence on the basal and nocturnal production of acid, resulting in an altered physiological output: a reduction in the hydrogen ion concentration and overall volume of gastric secretions.

Mechanistic Constraints on Total Acid Output

The H2 blockade mechanism does not interfere with acid secretion signals driven by gastrin or acetylcholine, which are active especially after meals. This means the drug modulates the acid output rather than eliminating it entirely, which establishes the physiological constraint of the mechanism.

Dosage and Administration Information

The administration of Ranitidine Hydrochloride follows strictly defined regulatory guidelines covering the approved routes, standardized dosage, frequency, and specific context of use.

Administration Routes and Forms

The medicine is available for both oral administration using film-coated tablets, and parenteral administration via a solution for injection. Parenteral administration, which includes intramuscular (IM) and intravenous (IV) injection (as a bolus, intermittent, or continuous infusion), is generally reserved for short-term use in clinical settings where the oral route is not feasible.

Standard Dosing and Frequency

For the treatment of active conditions, the standard oral regimen is 150 mg taken twice daily, or alternatively, 300 mg administered as a single dose once daily. Prophylactic maintenance therapy typically involves a lower, 150 mg oral dose once daily. The injectable dose is 50 mg administered every 6 to 8 hours. Official instructions specify that the total IV or IM dose should generally not exceed 400 mg within a 24-hour period.

Contextual Use and Adjustments

Specific guidance exists for administration timing: the once-daily oral dose is instructed to be taken either after the evening meal or at bedtime. For IV administration, the injection solution must be diluted to specific concentrations depending on the method (bolus or infusion) prior to use. A mandatory dosage reduction is required for patients with documented renal impairment (creatinine clearance less than 50 mL/min). In these cases, the oral dose is typically reduced to 150 mg once daily. The duration of treatment for active conditions is typically 4 to 8 weeks, though maintenance regimens may be extended up to one year.

Recent Clinical Evidence

Research evidence / Overview of studies for Ранитидин Софарма


Evidence for the Treatment and Prevention of Duodenal and Gastric Ulcers

The research examining the use of this medicine for stomach and intestinal ulcers was studied for across numerous short-term Randomized Controlled Trials. The main outcomes monitored included the objective endoscopic documentation of ulcer healing rates and patient-reported outcomes describing perceived discomfort. Findings describe patterns observed in the studies related to the duration over which healing outcomes were measured. Research explored whether healing outcomes measured in these studies had a longer required treatment duration compared to those measured in studies of certain other drug classes. Further research explored long-term controlled follow-up settings, which monitored patients for patterns related to ulcer recurrence.


Evidence for Gastroesophageal Reflux Disease (GERD) and Heartburn

Studies focusing on conditions characterized by fluctuating manifestations like GERD have included short-term clinical trials and systematic reviews. Research examined outcomes related to physical discomfort, primarily focusing on the frequency and severity of heartburn. Other studies monitored the healing of physical lesions in the esophagus. Studies reported measurements of symptom change in some patients during the study period. Comparative research has explored whether certain other drug classes show different patterns in the speed and completeness of symptom change. High-quality randomized data focusing on infants and children is generally less numerous compared to the adult population.


Evidence for Conditions of Pathological Gastric Acid Hypersecretion

This medicine was studied for conditions involving the stomach secreting an excessive amount of acid, such as Zollinger-Ellison Syndrome. The research utilized historical clinical trials, case series, and dedicated acid secretory studies. Outcomes monitoring physiological strain included the objective measurement of Basal Acid Output (BAO) and the ability to maintain a sustained increase in intragastric pH to target levels. Studies consistently reported measurements describing the change in volume and acidity of gastric secretions in the observed populations. Due to the rarity of certain hypersecretory conditions, evidence often relies on smaller patient cohorts and observational data, leading to evidence that is limited and heterogeneous in scope.


Long-Term Research and Durability of Response

Research exploring long-term outcomes included studies monitoring patients for patterns related to ulcer recurrence, with follow-up durations sometimes lasting up to several years. These studies monitored the maintenance of healing outcomes and the frequency of recurrence in patients on maintenance regimens. Findings describe group patterns related to ulcer recurrence measurements in maintenance treatment cohorts compared to un-treated groups. It is important to note that the follow-up durations were limited in many studies, and comprehensive long-term outcomes are not fully established beyond the specific periods studied. Furthermore, comparative evidence is lacking for the long-term durability of this medicine against alternative modern treatments used today.
